When to water houseplants: let the soil decide, not the calendar

Check the soil first

For most common houseplants, push a finger two to three centimetres below the surface. If the mix is still damp and cool at that depth, wait before watering.

When the mix is dry, the plant has no other warning signs, and the pot feels noticeably lighter, water it evenly. Empty excess water from the cachepot or saucer after a short while.

• Check below the surface, not just the dry top layer.
• Do not let water stand around the roots for long periods.
• Note the date after watering and compare the plant's condition next time.

The interval changes through the year

In warm summer weather by a bright window, the potting mix dries faster than it does in winter. The same plant may need checking after a few days in summer and after two weeks in winter.

Do not increase watering simply because the usual interval has passed. Check the soil first and adapt to the conditions in your home.

Overwatering can look like thirst

Yellowing or drooping leaves do not always mean too little water. In an overwatered plant, the mix stays wet for a long time, the pot feels heavy, and the roots do not get enough air.

If you are unsure, do not add more water. Let the mix partly dry, check the drainage hole, and watch new growth.

Frequently asked questions

How often should I water houseplants?

There is no single correct interval. Check the potting mix regularly and water only when it suits the needs of that species.

Frequently asked questions

Is it better to water in the morning or evening?

For houseplants, the condition of the soil matters more than the exact time of day. Water when you can check on the plant afterwards.
