Normal winter rest
A plant that has stopped growing between roughly October and March because day length and temperature have fallen, and which is otherwise in perfect health. It is the commonest reason a houseplant 'stops doing anything', and it is not a fault. Growth resumes on its own in spring without any intervention at all — and the interventions people reach for meanwhile, principally feeding and repotting, are the two most likely to cause a real problem.
What brings it on
Growth stalling from mid-autumn and restarting in early spring, on a plant whose existing leaves are firm and well-coloured. British winter daylight is a small fraction of midsummer's and reaches a plant indoors through glass and at a low angle, so even a bright windowsill supplies far less than it did in July. Most tropical foliage plants simply stop rather than decline.

Preventing it
Ordered by how much difference each measure actually makes, not by how often it is repeated.
- Nothing to prevent. Recognising it is the entire point, because the two standard responses to a plant that is not growing — feed it and pot it on — are both actively harmful to a resting plant. Fertiliser it cannot take up accumulates as salts around the roots, and fresh wet compost around a root ball that is not drawing water is the classic route to root rot.

Dealing with it once it is there
- Water less, feed not at all, and wait. Check the compost before watering rather than on a schedule — a resting plant in a cool room may go two or three weeks between waterings where the same plant in July needed it twice a week. Hold off repotting until growth restarts in spring.

- If you want growth through winter rather than a rest, the variable to change is light rather than food. More light in December will do something; feeding in December will not.

On sprays and treatments
GrowingHQ does not tell anyone what to apply, at what rate, or how often. Pesticide approvals differ by country, change without notice, and the product label is legally binding — it is also the document you are holding. What is described here is cultural and physical control, which is what a home grower can act on without a label in front of them.
