Frequently asked questions about plant care

How often should you water a houseplant?

There is no one-size-fits-all answer. The frequency depends on the plant species, the season, the pot, and the environment. The general rule: check the soil with your finger (or a moisture meter) before watering. If the soil is still moist on the surface, wait. It’s better to underwater than to overwater.

How can I tell if my plant is getting enough light?

Signs of insufficient light: stems stretching toward the window, pale foliage, stunted growth, and lower leaves dropping off. Signs of too much light: scorched leaves, yellow mottling, and rapid drying of the soil. Check your plant’s care guide for its specific needs.

When should you repot a houseplant?

The best time to repot is in the spring (March–May), when the plant starts growing again. Signs that it’s time: roots poking out the bottom of the pot, soil that dries out very quickly, and a plant that seems “cramped.” Young plants are generally repotted every 1 to 2 years, while mature plants are repotted every 3 years.

My plant is losing its leaves. What does that mean?

Leaf drop can be caused by a variety of factors: temperature shock (moving, drafts), water stress (too much or too little water), changes in light levels, pests, or simply the natural shedding of older leaves. Identifying the cause requires observing the rate, location, and appearance of the fallen leaves.

Which plant should I choose if I'm just starting out?

Some reliable choices: Pothos, Zamioculcas (Zanzibar Gem), Sansevieria (Snake plant), Philodendron and Dracaena. All of them are forgiving if you forget to water them, adapt to different light levels, and clearly signal when they need care.

My plants have gnats. What should I do?

Fruit flies (sciarid flies) are almost always caused by overly moist potting mix. Reduce watering, allow the surface of the potting mix to dry completely between waterings, and add a thin layer of sand, clay pellets, or our decorative moss to the surface. For stubborn infestations: spray with Super Neem Oil.
