Whether you are troubleshooting yellow leaves, choosing between potting mixes, or wondering how often to water a self-watering planter, this page gathers the questions we hear most from readers. Browse by topic, or reach out directly if your situation needs a closer look.
Straight answers about soil, watering, light, and keeping indoor plants alive without the guesswork.
Self-watering pots work through capillary action, so the soil stays evenly moist rather than cycling between dry and soaked. Check the reservoir every five to seven days and refill when it runs low. In winter, most indoor plants need less, so let the top layer dry slightly before topping up. The key is watching the plant, not the calendar.
A light, well-draining mix works best for basil, mint, and parsley. Combine two parts coco coir, one part perlite, and one part compost. This holds enough moisture without turning soggy, which is the main cause of root rot in small containers. Avoid garden soil, as it compacts quickly indoors and can carry pests.
Yes, especially in rooms with north-facing windows or short winter days. A full-spectrum LED placed about 20 to 30 centimeters above the foliage gives leafy greens and herbs the light they need to grow steadily. Run it for 10 to 12 hours a day and keep a consistent schedule. Without enough light, plants stretch and lose their color.
Fungus gnats usually appear when the soil stays too wet. Let the top two centimeters dry out between waterings and use a layer of coarse sand or fine gravel on the surface to block adults from laying eggs. Yellow sticky traps catch the flying ones, while watering from the bottom helps keep the surface dry.
Leafy greens like lettuce, spinach, and arugula grow well on a bright windowsill or under a grow light. They need about 12 hours of light and a pot at least 15 centimeters deep. Choose compact varieties and harvest outer leaves regularly to keep the plant producing. Root vegetables are trickier indoors, so stick to greens for reliable results.
When roots start circling the bottom or poking through drainage holes, it is time to move up one pot size, roughly two to four centimeters wider. Spring is the best moment, as plants are entering their active growth phase. Gently loosen the root ball, add fresh potting mix, and water well after repotting.
Straight answers to the questions that usually come up when you start growing herbs, leafy greens, and ornamentals in small spaces. No vague advice, just the practical details that make a difference on a windowsill or balcony.
It means the plant receives plenty of light but not direct sun rays hitting the leaves for more than a couple of hours. On a south-facing window, that usually means placing the pot a foot or two back from the glass or behind a sheer curtain. On an east or west sill, morning or late-afternoon sun is often fine without protection. If the leaves look pale or the stems stretch toward the window, the spot is too dark; if the edges turn brown or crisp, the sun is too harsh.
Check the water reservoir rather than the soil surface. Fill it only when the indicator shows it's low or when the top inch of substrate feels dry to the touch. In a cool room with low light, that might be every 10 to 14 days; in a warm, bright spot, it could be every 4 to 5 days. The capillary system keeps the root zone evenly moist, so you don't need to follow a fixed schedule. Just avoid letting the reservoir sit completely empty for more than a day.
It's not a good idea. Garden soil is dense, often contains weed seeds, and can carry fungi or insects that thrive indoors. It also compacts quickly in a container, which suffocates roots and leads to poor drainage. For potted plants, use a mix of peat-free compost, perlite, and coarse sand or fine bark. This keeps the structure airy and lets water flow through without waterlogging. If you want to use your own compost, sieve it and mix it with perlite at a ratio of about 2:1.
Leggy seedlings are almost always reaching for more light. They stretch upward, become pale, and have long, weak stems. Move them to a brighter spot or add a grow light placed just a few inches above the leaves. Also, avoid starting seeds too early in the season when daylight is still short. A simple fix is to brush your hand over the seedlings a few times a day; this mimics wind and encourages sturdier growth. Keep the soil evenly moist but not soggy.
Not immediately. Most nursery pots are fine for the first few weeks, and repotting right away can stress the plant, especially if it's flowering or in bud. Wait until the roots start circling the bottom of the pot or growing out of the drainage holes. Then choose a container only one or two sizes larger, and use fresh potting mix. If the plant looks root-bound or the soil smells sour, repot sooner. Otherwise, give it a week to adjust to your home before doing anything.
