Bougainvillea glabra

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 - 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-Winter · Outdoors

Water regularly

Water regularly at all times.

Adopt a regime whereby 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-Autumn · Planting

Prune after flowering

Generally reduce the plant in size by cutting back all the spreading branches and shoots, so there are only 3 or 4 buds on each stalk.

Summer-Autumn · Indoors

Mist the plant in warm weather

Revive plants in warm or hot weather by misting the foliage, preferably using soft or rain water which doesn't mark the foliage. Don't mist when the plant is in full sun. The plant can be misted twice daily if you notice the process revives it.

If leaves are covered in water drops when sun is on them, the droplets can act as little magnifying glasses and cause foliage scorch.

Winter-Spring · Indoors

Water lightly in winter

The soil should remain just moist during the cold months when the plant is not in growth. Trickle a little water onto the soil surface every couple of weeks if the soil is dry. Do nothing if it is moist.

The roots remain active in winter and benefit from small amounts of moisture so they don't become completely desiccated.

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
