Houseplant Care FAQ — Frequently Asked Questions
A collection of frequently asked questions about houseplant care, covering watering, lighting, repotting, pest control, and more
How often should I water houseplants?
The basic rule is to water thoroughly when the soil surface feels dry. Water until it drains from the bottom and always discard excess water from the saucer. In spring–autumn, water once or twice a week; in winter, wait 2–3 days after the soil dries. Overwatering causes root rot, so when in doubt, err on the dry side.
Where is the best place to put houseplants?
Most houseplants prefer bright indirect light. A windowsill behind a sheer curtain is ideal. Avoid direct sunlight (causes leaf scorch) and direct air conditioning (causes dryness). Low-light-tolerant species can grow further from windows.
What houseplants are best for beginners?
Pothos, Sansevieria (Snake Plant), Pachira (Money Tree), Monstera, and Ficus microcarpa are great choices. All are hardy and easy to maintain. Start with 1–2 pots. Browse listings in the Houseplants category.
When and how should I repot houseplants?
Spring (April–June) is best, and repot every 1–2 years. Use a slightly larger pot with drainage stones and houseplant potting mix. Keep the plant out of direct sunlight for 1–2 weeks after repotting. For repotting tips, consult a grower in the Houseplants category.
How can I deal with pests on houseplants?
Common pests include spider mites, scale insects, whiteflies, and aphids. Prevent them by regularly misting leaves. Remove scale insects physically with a toothbrush. For indoor plants, physical removal and environmental improvements are preferred over chemicals. If you need help, contact us.
Why are my houseplant leaves turning yellow?
The most common cause is root rot from overwatering. Other causes include insufficient light, over-fertilizing, cold damage, and natural leaf turnover. Identify the cause and adjust your watering schedule or placement accordingly.
How should I care for houseplants in winter?
Keep room temperature above 10°C (50°F). Move plants away from cold windowsills at night. Reduce watering and stop fertilizing in winter. Mist leaves regularly to counteract dry air from heating systems.
How can I propagate houseplants?
Methods include stem cuttings, division, water propagation, and air layering. Pothos and Philodendron root easily in water. Success rates are highest during the spring–summer growing season. For propagation tips, ask a grower in the Houseplants category.

How should I fertilize houseplants?
Fertilize during the growing season (April–October) and stop in winter. Apply slow-release granular fertilizer every 2 months, or liquid fertilizer every 2 weeks. Do not fertilize right after repotting or when the plant is weak. Always follow the recommended dosage.
