Your houseplant is losing leaves – here’s what helps

By PlantlySources checked on 23 October 20264 min read

In short

Another leaf on the windowsill? An occasional older leaf is usually nothing to worry about if the plant otherwise looks healthy. If lots of leaves suddenly fall, look in the pot first: dry soil and persistent wetness need different responses. A new position, drafts or pests could also be involved.

In this guide

One fallen leaf is not an emergency

Even healthy houseplants do not keep their leaves forever. An older leaf near the base may occasionally yellow and fall while the rest of the plant looks well. That is often normal leaf turnover.

If the plant quickly becomes bare or starts wilting too, take a closer look: are only the oldest leaves affected, or younger ones as well?

Feel the soil before reaching for water

Lift the inner pot and gently feel a few centimetres down into the mix. Is the pot heavy and the mix still damp? A dry surface can be misleading. Pour away any water collected in the outer pot.

The following steps are for ordinary potting mix. How far it should dry depends on the species: succulents need drier conditions than many tropical foliage plants. Orchids in bark and plants grown without soil need different routines.

The soil is wet, but the leaves still droop

It looks like thirst, but the roots may be struggling. Damaged roots cannot supply the leaves properly even when water is available. Adding more water will not help.

If the root ball stays wet and the plant wilts further, gently ease it out of the pot. Soft, mushy roots or a soft stem base are warning signs. Our guide to rescuing an overwatered houseplant explains what to do next.

The pot feels light and the mix is dry

Dry mix, an unusually light pot and curled leaves or crisp edges are consistent with a lack of water. Water slowly until it runs out below, then let the pot drain thoroughly.

If the mix has pulled away from the pot’s sides, water may simply run around it. Several slow applications may be needed to help the mix take up moisture again. Empty the outer pot afterwards.

Has the plant moved?

From a bright balcony to the living room, or from the window to a shelf: that can be a big change in light. A weeping fig, Ficus benjamina, for example, may shed a lot of leaves when it receives less light.

Choose a position that suits the species. A plant from a dark corner needs a gradual introduction to stronger light. If you are unsure how bright the new spot really is, our guide to light for houseplants will help.

Warm radiator, cold window

A spot can be warm in the morning and suddenly cold when you open a window. Some houseplants struggle with those temperature swings. Right beside a radiator, it may also become too hot.

Notice what happens around the plant over the course of the day. Protect it from cold airflow and direct heat. The right temperature depends on the species.

It is worth looking under the leaves

Watering and light are not the only reasons for leaf loss. Gently turn a leaf over and look where the leaf stalk meets the stem too.

Fine webbing with pale speckles points towards spider mites. White, cottony clusters suggest mealybugs; sticky leaves can be a sign of sap-feeding insects. A magnifying glass helps. If you find pests or suspicious signs, keep the plant apart from others and identify the pest before treating it.

When a little patience helps

After coming indoors in autumn, the plant needs time. If its pot and foliage otherwise look healthy, suitable, steady conditions help. Avoid moving it every day.

Is the leaf drop easing? Good. If the plant wilts further or develops fresh damage, revisit the clues above. Warning signs need attention.

Your checklist

Tick off what you have already checked. Nothing is saved.

Are only occasional old leaves falling, or is the plant quickly becoming bare?
Feel below the surface of the mix and lift the inner pot.
Empty any water collected in the outer pot.
Think back to a recent move, heating coming on or open windows.
Look under leaves and along stems for pests and webbing.
Inspect the roots if the root ball is wet and wilting is getting worse.

Frequently asked questions

How long can leaf drop last after bringing a plant indoors?

Adjustment may take several weeks. Iowa State gives roughly one to two months for the move from outdoors to indoors. That is not a reason to wait when there are warning signs: wet mix with worsening wilt, a soft base or pests need attention sooner.

Do I need to repot the plant now?

Leaf drop alone does not call for repotting. What you find in the pot matters. Rotten roots or persistently unsuitable potting mix may need addressing. An otherwise healthy plant that has recently moved often mainly needs appropriate conditions.

Should I cut off damaged leaves?

You can remove completely dead leaves with clean tools. Keep leaves that are still mostly green for now, as they continue to help the plant. Cutting it back hard is not a general treatment for leaf drop.

A photo today makes the next comparison easier

In Plantly’s plant journal, save a photo and a short note about a change in location. The next photo makes it easier to see which areas were already bare and whether anything has changed.
