Ampelopsis

Spring-Autumn · Indoors

Feed with houseplant food monthly

Give the plant a balanced houseplant feed monthly while in growth.

Where food elements are listed as three numeric values on the label representing in order Nitrogen(N)-Phosphorus(P)-Potassium(K), with percentage values for each, choose one where the values are more or less equal.

Spring-Autumn · Indoors

Water regularly during growth

Water regularly while in growth.

Adopt a regime that means the plants are thoroughly watered every week so that they do not become dessicated. In hot weather watering may need to be more frequent, but less often in cool or moist conditions.

Spring-Winter · Indoors

Don't water while dormant

Keep the compost or the plant tuber, rhizome or bulb completely dry when the plant is dormant.

The plant requires a rest period in order to thrive. Watering at this time may prevent dormancy, or may induce rot or disease.

Spring - late · Outdoors

Feed with slow release fertiliser

Apply a general purpose slow release fertiliser, spreading it around the root area of the plant as it is coming into growth. (Or apply a liquid feed at regular intervals throughout the growing season.)

This is a simple way to provide a nutrient boost as a single annual procedure.

Spring-Autumn · Outdoors

Water in dry periods

Established plants in the ground can cope with 7-10 days of dryness, and shrubs often manage 2 to 3 weeks. Water one section of the garden thoroughly each day rather than a little everywhere. Check plants in pots more often, especially in hot weather.

Winter - late · Planting

Prune to maintain the plant

Remove and dead or damaged branches or any growth that looks very untidy. Trim the plant back if necessary to keep it within bounds.

Outdoors

Water some varieties differently

Some plants within this genus have additional requirements for water. It is best to look up your specific plant, or the species it belongs to for watering guidance.

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.

Indoor temperature · Planting

15C minimum temperature

This plant requires a minimum temperature of 15 Centigrade.

Indoor plant · Planting

Position in indirect light indoors

Give the plant a position that is cool and light, and away from direct sunshine.
