Primula obconica

Autumn · Planting

Remove offsets to create new plants

Offsets are small plants or shoots that develop around the parent plant. They should have developed a root system of their own before they are detached. They can be planted directly, or grown in pots if so small they could be 'lost' in the garden.

Spring-Autumn · Indoors

Feed with houseplant feed

From spring until autumn feed weekly with a half strength balanced houseplant fertiliser.

Where food elements are listed as three numeric values on the label representing in order Nitrogen(N)-Phosphorus(P)-Potassium(K), choose one where nitrogen has a high value.

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-Autumn · Outdoors

Water to keep the soil moist

For best results, this plant needs soil that is always moist. Water deeply and regularly as soon as soil appears dry. Even for established plants in the ground, a dry week can cause problems with some soils. Check plants in pots more often, especially in hot weather. Or install an automatic irrigation system which will do the hard work for you, even when you are away on holiday.

Without regular watering some plants never fully regain their beauty.

Winter · Indoors

Water lightly during dormancy

The soil should be kept just moist during the plant's rest period.

Outdoors

Water with rain water

This plant needs rain water or soft water (the minerals in alkaline or "hard" water are harmful). This is especially important for plants in pots.

Compost · Planting

Loam based compost for repotting

Repot using any good quality standard compost.

Alternatively prepare a special compost that is best suited to the plant's needs: mix equal amounts of loam (John Innes no. 2 or 3), leaf mould, sand or grit and perlite.

Indoor temperature · Planting

0C minimum temperature

This plant requires a minimum temperature of 0 Centigrade.

Compost · Planting

Multi-purpose compost

Use a good quality peat-free multi-purpose compost when growing in pots and containers.

Indoor plant · Planting

Position in indirect light indoors

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