Spring-Winter · Indoors

Soak completely when watering

Water until water comes out of the bottom of the pot. Leave for 30 minutes or so until the compost is fully moist, then pour away the excess water so the plant pot is not standing in water. (This avoids waterlogging which can cause "root rot".)

Spring · Planting

Trim foliage

Trim foliage in spring to induce new growth and keep the plant looking fresh.

Compost · Planting

Loam based houseplant compost for repotting

Buy container or house plant compost that is loam based if possible (i.e. is based on John Innes compost number 2 or 3. This contains more fertiliser and is better suited to established plants.

John Innes no. 1 has the lowest level of fertiliser and is used for seedlings and young plants, so is generally used where plants will be 'potted on' after a number of weeks.
