Why are my plant leaves turning yellow?

Yellow leaves are usually a sign of overwatering, dry air from radiators, or hard water build-up, so you need to check the soil moisture and the leaf texture to pinpoint the exact cause. If the soil is soggy and the roots feel mushy, you are likely dealing with root rot, but if the soil is dry and the air is very hot, the plant is probably thirsty. Identifying the pattern of yellowing will tell you exactly which of these environmental shocks is happening and how to adjust your routine.

My plant’s soil feels like a swamp, what do Do?

A heavy pot that feels like a brick is a classic sign of waterlogging, which invites root rot and can kill your plant if you keep watering it. You should stop watering immediately and let the soil dry out completely, or gently remove the plant to inspect the roots for any that have turned brown and mushy. If the roots are healthy, simply repot the plant in fresh, well-draining compost to give it a fighting chance. Full details in our guide to How to Save an Overwatered Plant from Root Rot.

The tips of my leaves are crispy and brown, is that underwatering?

Crispy brown tips are often caused by low humidity rather than a lack of water, especially in British homes where radiators dry the air out quickly. You can tell the difference by checking the soil; if it is bone-dry and the leaf feels papery, the plant needs a drink, but if the soil is moist and the edges are curling, the air is too dry. In winter, central heating can dry the air three times faster than the soil dries out, so you end up with a well-watered plant that still looks scorched.

My houseplant is drooping, should I water it immediately?

Drooping leaves usually mean your plant is thirsty, but if the soil is still wet and the leaves feel limp with a faint mouldy smell, you are likely dealing with root rot instead. You need to check both the soil moisture and the leaf texture to get it right, as misting or watering more will only make a rotting plant worse. The honest answer is that you need both soil and leaf clues to decide whether to give it a drink or let it dry out. Full details in our guide to Why Is My Houseplant Drooping?

Why are my succulent leaves falling off?

Succulent leaves falling off are almost always caused by overwatering, extreme dryness from radiators, or a lack of light during the winter months. You can usually bring them back if you catch it quickly by checking if the stem is squishy (indicating rot) or if the leaves are wrinkled (indicating thirst). If the stem feels like a damp sponge, it is likely a goner, but if the base is firm, you can often revive it with a change in care.

There is white fluffy mould on the surface of my soil, is my plant dead?

White, cottony fluff on the soil is usually a harmless saprophytic fungus feeding on decaying matter, but it is a massive warning sign that your soil is staying too wet or lacking airflow. It does not attack the plant itself, but it indicates that your living conditions are off, so you need to dry the surface and improve ventilation to stop it coming back. In a typical UK flat, this often happens because the soil is retaining moisture from the air or hard water build-up. Full details in our guide to Why Is My Houseplant Getting Mould on the Soil?.

Why are my plant leaves curling up?

Curling leaves are a classic stress signal reacting to dry air, hard tap water, or a cold draft, so you need to run a quick check on your soil moisture and the temperature around the pot. If the radiator is blowing hot air straight onto the plant, the air is likely too dry and sapping moisture from the leaves faster than you think. A simple move to a spot with better airflow or a little extra humidity can often sort this out within 48 hours. Full details in our guide to Why Are My Plant’s Leaves Curling? UK Causes & Fixes.

My plant looks like it’s dying, what is the first step?

Most dying houseplants in British homes are suffering from winter overwatering, radiator-scorched air, or hard tap water, so you should start by checking the soil to see if it is wet and smells sour. If the soil is soggy, stop watering immediately and trim away any brown, mushy roots to stop the fungal infection from spreading. You can usually bring them back from the brink by identifying exactly which of these environmental shocks is happening and adjusting your routine.

How do We know if my plant has root rot?

Root rot is usually identified by a sour smell coming from the soil and roots that feel brown, mushy, and slimy rather than white and firm. You can confirm this by gently teasing a few roots out of the pot; healthy roots are firm and white, while rot-affected roots turn dark and give off a faint, unpleasant odour. That smell is the silent killer of many UK houseplants, especially when the heating goes on and you instinctively water more often to compensate for the warm room.

Is misting my plant a good way to fix crispy leaves?

Misting feels like the obvious fix for crispy leaves, but in a typical British home, it is often about as useful as a chocolate teapot because the radiator just sucks the moisture straight back out. You need to determine if the issue is underwatering or low humidity by checking both the soil and the leaf texture to get it right. If the soil is moist but the leaf edges are curling and crispy, the air in your room is too dry and needs a more permanent solution than a quick spray.

Why are the bottom leaves of my plant turning yellow?

Yellow leaves at the base of the plant are usually the plant shedding old foliage or a sign of underwatering, but you need to look at the texture of the leaf to be sure. If the leaves are yellow and dry, the plant is likely just getting older, but if they are yellow and limp, it could be a sign of overwatering or early root rot. You should inspect the leaf margins and feel the soil to see if it stays soggy for days or dries out quickly to diagnose the problem.

My plant is drooping even though I watered it, what’s wrong?

A drooping plant that has been watered might be suffering from root rot rather than thirst, so you need to check the soil moisture and the leaf texture to get it right. If the soil is wet and dark and smells faintly of a damp pond, the roots are likely suffocating and need to be repotted in fresh soil. If the soil is bone-dry and crumbles, the plant is simply thirsty, but you need both clues to decide on the correct course of action. Full details in our guide to Why Is My Houseplant Drooping?
