Quick answers

What do houseplants need to survive?

Every houseplant needs the right amount of light, water when its soil dries to the right depth, a pot with drainage, an airy potting mix and temperatures that suit it, usually between 60 and 80°F (15 to 27°C).

Is it better to water houseplants from the top or bottom?

Both work. Water from the top until it drains out of the hole, or bottom-water by letting the pot soak up water from a tray for 15 to 30 minutes. Always empty any water left standing in the saucer.

When should I repot a houseplant?

Repot in spring or early summer when roots grow out of the drainage holes or circle the pot, or when water runs straight through. Go up only 1 to 2 inches in pot size.

Do houseplants need fertilizer?

Yes, during the growing season. Feed with a balanced liquid fertilizer at half strength every 2 to 4 weeks in spring and summer, and stop or cut back in autumn and winter.
