Spring-Autumn · Indoors

Feed with houseplant food monthly

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 sequestrol

If plants are acid loving and grown in soil with little acidity, or in a container, or are watered with limey tap water an annual feed with sequestrol (iron chelate) is highly beneficial. Follow guidelines on the packet. Will also 'blue-up' hydrangeas.

For hydrangeas that have good blue flowers in acid soil, this product can be used with alkaline soil to turn the flowers blue. This is most effective when the soil is neutral or just slightkly alkaline.

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.

Spring-Winter · Outdoors

Keep the leaves dry

The leaves should be kept dry, so avoid splashing them while watering.

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.

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, and fine bark.
