How do You Germinate Calendula?

Calendula (also called pot marigold) is one of the easiest flowers to grow from seed. You can start your seeds indoors 6–8 weeks before the last frost or sow them directly in the garden after the soil warms up. Just a few simple steps will give you bright, cheerful blooms that attract pollinators and even have edible petals.
Are Coffee Trees Evergreen?

Yes, coffee trees are evergreen. They keep their dark, glossy leaves throughout the year instead of dropping them all at once like deciduous trees. This evergreen nature is one of the reasons coffee plants can produce fruit and flowers on the same branch at the same time. ## What Does It Mean for a Plant to Be Evergreen? Evergreen plants keep their leaves for more than one growing season. They shed old leaves gradually, so the plant always looks green. This is different from deciduous plants, which lose all their leaves in autumn or during a dry season. Coffee trees are broadleaf evergreens. Their leaves are thick and waxy, which helps them hold onto water. That is useful because coffee grows best in mild, rainy climates where the soil stays moist but drains well. A common mistake is to think evergreen means the plant never loses leaves. It does lose leaves, just not all at once. Old leaves near the bottom of the tree turn yellow and fall off, often during the dry season or after a heavy fruit harvest. ## Are Coffee Trees Considered Evergreen or Deciduous? Coffee trees are firmly in the evergreen group. In nature, they grow under taller trees in tropical forests. The canopy above protects them from strong sun, and the evergreen leaves help them photosynthesize all year. The two main coffee species, Coffea arabica (arabica) and Coffea canephora (robusta), are both evergreen shrubs or small trees. Arabica is more common for home growing and commercial coffee, while robusta is hardier but less flavorful. There is no deciduous coffee tree. If you see a coffee plant that loses all leaves at once, it is likely suffering from cold stress, root rot, or a pest problem. Healthy coffee trees stay green year-round in the right climate. ## Do Coffee Trees Lose Their Leaves? Yes, but not dramatically. Coffee trees shed old leaves gradually, especially from the lower branches. A mature tree might drop a few leaves each week. You might notice a layer of dry leaves under the tree, but the upper part stays full and green. Heavy leaf drop happens after a big harvest. The tree puts energy into growing coffee cherries, so some older leaves fall off as the fruit ripens. This is normal. If you see leaves turning yellow or brown quickly and falling in large numbers, check for overwatering or poor drainage. One thing that surprises new coffee growers is that the tree can hold leaves for two to three years. Each leaf lives a long time before it is replaced. That is why the coffee canopy remains dense. ## What Does the Coffee Tree Look Like Year-Round? The coffee tree looks like a small, bushy tree or large shrub. In the wild it can grow 15 to 30 feet tall, but on farms it is pruned to 6 to 8 feet for easy picking. - Leaves: Dark green, glossy, oval-shaped, with pointed tips. New leaves are lighter green and slightly reddish. They grow opposite each other along the branches. - Flowers: Small, white, fragrant blooms that appear in clusters. They look a bit like jasmine flowers and smell sweet. - Fruit: Called coffee cherries, they start green, turn yellow, then ripen to bright red or dark purple. - Bark: Smooth, light brown to gray, with a slightly cracked texture on older trunks. Because it is evergreen, you can see all these parts on the same tree: flowers, green cherries, ripe cherries, and old leaves. That is unusual for fruit trees. For example, an apple tree flowers before leaves come out and loses leaves after harvest. A coffee tree never goes bare. ## How Does Being Evergreen Affect Coffee Growth and Harvest? Being evergreen gives coffee trees an advantage. They can photosynthesize and store energy all year. This is key for a plant that needs to produce a crop every year. Coffee cherries take about 9 months to ripen, sometimes longer for arabica at high altitudes. The tree needs a steady supply of energy from sunlight during those months. Evergreen leaves provide that. The tree also uses its leaves to store carbohydrates. When the tree is producing lots of fruit, it can draw energy from older leaves. That is why a heavy crop often causes some leaf drop afterward. Because coffee is evergreen, it does not need a winter dormancy period like many fruit trees. It grows continuously, though growth slows during the dry season. This means coffee can be harvested once a year in most regions, but flowering and fruiting can happen across several months. ## Can Coffee Trees Grow Indoors? Yes, with the right conditions. Coffee trees make popular houseplants because of their shiny leaves and compact size. But remember: they are evergreen and need consistent care to stay healthy indoors. For an indoor coffee tree, you need: - Bright, indirect light: No direct sun, which can scorch leaves. A spot near an east or west window works well. - Humidity: Coffee trees love humidity above 50%. Use a pebble tray or mist the leaves regularly. In dry winter air, leaves may develop brown edges. - Well-draining soil: A mix of potting soil, perlite, and a little sand or coconut coir helps prevent root rot. - Consistent moisture: Water when the top inch of soil feels dry. Do not let the plant sit in water. If you want to try growing coffee indoors, a young coffee plant is a good start. Many home gardeners buy a small plant online or at a nursery. Indoor coffee trees rarely produce cherries unless you have good light and hand-pollinate the flowers, but the plant itself is beautiful. To help you keep track of soil moisture, you might like a simple moisture meter that tells you when to water. Overwatering is the top killer of indoor coffee trees. Check out affordable moisture meters on Amazon. ## What Kind of Care Do Evergreen Coffee Trees Need? Coffee trees are not hard to care for if you mimic their natural environment. Here is a simple checklist for a healthy coffee tree: | Care Need | What to Do | |-----------|------------| | Light | Bright, indirect light. Avoid full afternoon sun. | | Water | Keep soil evenly moist but not soggy. Water when top inch is dry. | | Soil | Acidic, well-draining potting mix (pH 6–6.5). | | Fertilizer | Use a balanced, slow-release fertilizer every 2 months during growing season. | | Pruning | Prune in early spring to shape the tree and remove dead branches. | | Temperature | Ideal 60–80°F (15–27°C). Do not let it drop below 40°F. | | Repotting | Repot every 2 years in a slightly larger pot to refresh soil. | Pruning is important for shape and airflow. Use sharp pruning shears to make clean cuts. Dull tools can tear the bark and invite disease. Find quality pruning shears on Amazon. Fertilize regularly but lightly. Coffee trees are not heavy feeders, but they need micronutrients like iron and zinc, especially if grown in pots. A liquid fertilizer made for acid-loving plants works well. ## Where Do Coffee Trees Grow Best? Coffee trees grow best in the "bean belt" around the equator, between the Tropic of Cancer and the Tropic of Capricorn. That includes parts of Central and South America, Africa, and Asia. Key conditions: - Temperature: Average 60–75°F year-round. No frost. - Rainfall: 60–100 inches per year, with a dry season of about 3 months. Too much rain can cause root disease. - Altitude: Arabica grows best at 2,000–6,000 feet. Robusta grows at sea level up to 2,000 feet. - Shade: In many regions, coffee is grown under taller trees like banana or citrus to protect it from sun. If you live in a cooler climate, you can still grow coffee as a houseplant or in a greenhouse. The evergreen nature makes it a great candidate for containers because you can move it indoors when temperatures drop. ## Are There Different Varieties of Coffee Trees? Yes, there are many varieties within the two main species. All are evergreen. Here are a few common ones: - Typica: The original arabica variety. Tall, high-quality beans, but low yield. - Bourbon: A natural mutation of Typica. More productive, with sweet flavor. - Caturra: A dwarf variety from Brazil that stays small, good for containers. - Catuaí: A hybrid of Caturra and Mundo Novo, resistant to wind and heavy rain. - Robusta: Hardier, tolerates lower altitudes and more pests, but beans are stronger and less aromatic. For home growing, dwarf varieties like Caturra or Catuaí are easier to manage because they stay under 6 feet tall. Their evergreen leaves still make them attractive year-round. If you want to start from seed, you can buy green coffee beans that are raw and untreated. But be patient: coffee seeds take 1 to 2 months to germinate. Shop for coffee tree seeds on Amazon. ## How Long Do Coffee Trees Live? Coffee trees are long-lived for a fruit tree. They produce well for 15 to 20 years, and can live 30 to 50 years in the wild. The oldest known coffee tree in a botanical garden is over 100 years old. Productivity declines after about 20 years. Farmers often replace trees or prune them hard to rejuvenate growth. But as an ornamental evergreen, a coffee tree can be a lifelong companion in your home or garden. The tree's age does not change its evergreen habit. Old trees still hold leaves through all seasons. They just grow slower and produce fewer cherries. Remember that a coffee tree in a pot will have a shorter lifespan than one in the ground. Container roots get pot-bound over time, which limits growth. Regular repotting helps extend its life. ## What Are Common Problems with Evergreen Coffee Trees? Even though coffee trees are tough, a few issues can make them lose leaves or look sick. - Leaf yellowing: Often from overwatering or poor drainage. Let the soil dry a bit between waterings. - Brown leaf tips: Low humidity or salt buildup from fertilizer. Use filtered water and flush soil occasionally. - Drooping leaves: Can be under-watering or too much direct sun. Move to a shadier spot. - Pests: Aphids, scale, and spider mites can attack indoor trees. Wipe leaves with a damp cloth or use insecticidal soap. Because coffee trees are evergreen, leaf problems are easier to spot. A healthy tree always has a full, rich green look. If you see bare branches, something is wrong. A good way to prevent issues is to use a balanced liquid fertilizer formulated for evergreens or acid-loving plants. This gives the tree the nutrients it needs to stay glossy and strong. See top-rated liquid fertilizers on Amazon. ## Does the Evergreen Nature Affect Coffee Flavor? Not directly, but it does affect how the tree handles stress. An evergreen tree can store reserves in its leaves, which helps it survive dry spells and produce consistent crops. Consistent crops mean consistent bean development, which translates to better flavor. When coffee trees are stressed from drought or poor soil, they may drop leaves and reduce fruit quality. Because they are evergreen, they can recover faster than deciduous trees. They do not need to regrow all leaves from scratch. Some specialty coffee growers believe that trees grown in shade with lots of leaf cover produce slower-ripening cherries, which leads to higher sugar content and better flavor. The evergreen canopy itself provides that shade. ## Would You Recommend Growing a Coffee Tree? If you want a beautiful evergreen houseplant that also produces coffee cherries (with some patience), a coffee tree is a great choice. It requires moderate care but rewards you with glossy leaves and fragrant flowers. Even without fruit, it adds a tropical feel to any room. For outdoor growing, check your local climate. Coffee trees are hardy only in USDA zones 10–11. Anywhere else, keep them in pots and bring them inside when temperatures drop below 40°F. Coffee trees are not high-maintenance, but they do need consistent attention. If you travel a lot, consider setting up a simple drip irrigation timer for potted trees. They do not like being forgotten. In short, yes, coffee trees are evergreen, and that is part of what makes them such adaptable and long-lived plants. Whether you grow one for the beans or just for the look, you will enjoy its year-round greenery.
How do Plants Release Oxygen into the Air?

Plants are natural oxygen factories. Through photosynthesis, they use energy from sunlight, water, and carbon dioxide to make food and release oxygen as a byproduct. This process is essential for most life on Earth, including humans.

Do Little Gem Magnolia Trees Lose Their Leaves?

Little Gem magnolia trees are semi-evergreen, meaning they lose some leaves but never go completely bare. They drop older leaves gradually throughout the year, with a heavier shed in late spring and sometimes after cold weather. So yes, they do lose leaves, but it's a normal process and not a sign of a dying tree.
How do You Get Rid of Black Mold in Soil?

Black mold in soil is usually a harmless saprophytic fungus that feeds on organic matter, not the toxic Stachybotrys mold found in damp buildings. Getting rid of it mostly means drying out the soil, improving air flow, and removing the surface mold. The simplest fix is to scrape off the mold, let the soil dry, and add a light sprinkle of cinnamon or baking soda to prevent regrowth.
Are Sunflower and Pumpkin Seeds Good for You?

Sunflower seeds and pumpkin seeds are tiny nutrition powerhouses packed with healthy fats, protein, fiber, and essential minerals. Eating a handful of these seeds regularly can support heart health, improve digestion, and help you feel fuller longer—making them a smart addition to most diets.
Are Ants Good for My Lawn?

Ants can be both helpful and harmful to your lawn. In small numbers, they aerate the soil and break down organic matter, which benefits grass roots. But when ant mounds become large or ant populations explode, they can smother grass and attract other pests. Understanding the balance will help you decide whether to leave them alone or take action.
Do Orchids Like to Be Rootbound?

Orchids are unique plants that don't follow the same rules as most houseplants. While they do enjoy being snug in their pots, they do not actually like being fully rootbound in the way many people think. Instead, orchids thrive in a tight but not completely packed environment that still allows air to circulate around their roots. What does it mean for an orchid to be rootbound? A plant is rootbound when its roots have completely filled the pot and started circling around the inside. For most houseplants, this is a problem because the roots choke themselves and can't get enough water or nutrients. But orchids are different. They are epiphytes, which means they naturally grow attached to tree bark or rocks, not in soil. Their roots are designed to grip onto surfaces and get moisture and air from the environment. When you put an orchid in a pot, it naturally wants to wrap its roots around the bark chunks or the pot walls. That snug feeling actually mimics how they grow in the wild. So a pot that is slightly tight feels normal to them. But if the roots are so packed that they can't breathe or if they start pushing the plant upward out of the pot, then the orchid is too rootbound and needs help. Do orchids like to be rootbound or not? The short answer is: orchids like a tight fit, but they do not like being completely rootbound. There is a difference. Think of it like wearing a comfortable shoe that fits well versus wearing a shoe that is so tight your toes are crushed. Orchids prefer a pot that is just big enough for their roots to hold onto. They actually bloom better when their roots are a little crowded. That's because the tight space tricks the plant into thinking it is running out of room, which often triggers it to produce flowers. However, if the pot is too small and the roots are completely tangled with no space for air, the roots can rot or suffocate. So the goal is to keep your orchid in a pot that is cozy but not strangled. Many orchid experts say that a Phalaenopsis orchid (the most common type) is happiest when its roots completely fill a clear plastic pot but still have tiny gaps for air. How can you tell if your orchid is rootbound? You do not have to guess. There are clear signs that your orchid is getting too cramped. Look for these clues: Roots growing out of the pot: If thick white or green roots are crawling out of the drainage holes or over the top rim, the plant is looking for more space. The pot is cracking or bulging: As roots multiply, they can push outward and distort a plastic pot. The orchid is unstable: If you tap the pot and the plant wiggles or feels loose, it may be because all the space is taken by roots and the bark has broken down. Water runs right through: When a pot is packed solid with roots, water has nowhere to go except straight out the bottom, and the bark doesn't hold moisture anymore. Leaves are wrinkled or wilted: Even with regular watering, a severely rootbound orchid can't absorb enough water because there is no healthy potting medium left. If your orchid shows one or two of these signs, it is rootbound. If it shows three or more, it is urgently rootbound and needs repotting soon. When should you repot a rootbound orchid? You should repot your orchid when it becomes too rootbound, but timing matters. The best time to repot an orchid is right after it finishes blooming. Repotting while the plant is in flower can cause the buds to drop. Also, wait until you see new root growth starting — usually in the spring. New roots are more resilient and will adjust faster to a new pot. Here is a simple guideline: If roots are crawling out but the plant looks healthy and is blooming, wait until the blooms fade. If the potting bark has broken down into mushy pieces, repot immediately even if it means losing some buds. If the roots are rotting or have black spots, you need to repot as soon as possible to save the plant. Most orchids need repotting every 1 to 2 years. Some may need it sooner if they are fast growers. If you see roots completely filling a 4-inch pot and starting to circle, it is time. What happens if you leave an orchid rootbound too long? Leaving an orchid rootbound for too long can cause several problems. First, the potting medium breaks down over time. Orchid bark chips decompose into smaller particles that hold too much water. That can lead to root rot, which is the number one killer of orchids. Second, when roots are packed tightly, they have no air circulation. Orchid roots need air — they get oxygen from the air, not from soil. Without air, they suffocate and die. Third, a very rootbound orchid may stop growing leaves and stop blooming. It will just survive, not thrive. In severe cases, the roots can girdle each other, strangling the main stem. Eventually, the plant may become so unstable that it topples over. So while a little tightness is fine, leaving your orchid rootbound for years is harmful. It's like living in a closet — you might survive, but you won't be happy. How to properly repot a rootbound orchid Repotting a rootbound orchid is not hard if you follow the right steps. You will need a few supplies: new potting bark, a clean pot (only one size larger), and sterilized shears or scissors. Here is a step-by-step guide: Remove the orchid from its old pot. Gently squeeze the pot to loosen the roots. If the roots are stuck, cut the pot away with scissors. Do not pull hard on the plant or you may break healthy roots. Clean the roots. Shake off all the old bark and debris. Rinse the roots with lukewarm water to see them clearly. Healthy roots are firm and green or white. Rotten roots are mushy and brown or black. Trim dead roots. Use sterilized pruning shears to cut away any rotten, hollow, or dried-out roots. Leave only healthy roots. Do not cut green roots even if they are long and tangled. Choose the right pot. You want a pot that is about 1 to 2 inches wider in diameter than the old one. Do not go too big — a huge pot stays wet too long. A clear plastic pot with good drainage holes is ideal because you can see the roots. Add bark and position the orchid. Put a layer of fresh orchid bark in the bottom of the pot. Set the orchid so the base of the leaves sits just at the rim. Then fill in around the roots with more bark, tapping the pot to settle it. Do not pack the bark down hard — you want air gaps. Water sparingly for a week. After repotting, wait 5-7 days before watering. This gives any cut roots time to callus over and reduces the chance of rot. Then resume your normal watering routine. Clear orchid pots with side drainage slots are excellent for keeping roots healthy because they let light in (which helps roots photosynthesize) and allow air flow. Also consider using a good quality premium orchid bark mix that includes charcoal and perlite for better drainage. What kind of pot is best for orchids? The best pot for an orchid is one that provides good drainage and airflow. Orchids do not like sitting in water. Plastic pots are common, but they must have plenty of holes. Clear plastic pots are popular for Phalaenopsis orchids because you can see the roots and monitor their health. When roots are green, they have enough water. When they turn silvery, it is time to water. Terracotta pots can also work, but they dry out faster and can attach roots to the clay, which makes repotting harder. Avoid pots without drainage holes — those are death traps for orchids. Also, skip the idea of putting a layer of stones at the bottom. That does not improve drainage; it just reduces pot depth. Use a pot with holes all over the sides if possible. Many specialty orchid pots have slits or netting.

That helps the plant bounce back faster. How to tell when your orchid is just the right snugness You want the pot to be full of roots, but not packed so tight that you cannot see any bark. When you remove the orchid from its pot, the root ball should hold together but still have visible chunks of bark. You should be able to gently pull the root mass apart with your fingers without breaking roots. If the roots are so tangled you need to cut the ball, it is too rootbound. If you can pull the plant right out and see loose roots, it is not snug enough. The ideal is that the roots have naturally wrapped around the bark but there is still air between them. Many experienced growers say that an orchid should be repotted when the root ball is about the size of the pot and the roots are starting to crawl around the inside edge. That is the sweet spot—the orchid is happy and will likely produce a flower spike soon. Can you prevent your orchid from getting rootbound? You cannot stop an orchid from growing roots, and you shouldn't try. Roots are good. But you can control how quickly it becomes rootbound. The main trick is to use a pot that is only slightly larger than the root ball. If you start with a pot that is too big, the roots will grow slowly and the medium will stay wet too long, leading to rot. Also, use a chunky bark mix that does not break down quickly. High-quality bark lasts 1-2 years. Cheaper mixes turn into mush in months. Finally, repot on a regular schedule every 1-2 years, even if the plant doesn't look rootbound yet. That way you replace the bark before it degrades and remove any circling roots before they cause problems. If you catch it early, your orchid will stay healthy and bloom reliably.
Does Ivy Plant Have Flowers?

Yes, ivy plants do have flowers, but they only appear on mature vines that are several years old. The blossoms are small, greenish-yellow, and often hidden among the leaves, followed by dark berries that birds love. If your ivy never seems to bloom, it is likely still in its juvenile growth stage.
Do You Feed Houseplants in the Winter?

Yes, you do feed houseplants in the winter, but much less often than in spring and summer. Most indoor plants enter a resting period when days are short and light is weak, so they need very little extra food. Overfeeding during winter can damage roots and cause weak, leggy growth.
