Citrus x aurantium

Autumn · Planting

Reduce fruit to prevent branches breaking

Inspect the tree as fruit grows - reduce the numbers of fruit at the ends of branches to prevent branches breaking under their weight. This will also increase the size of remaining fruit. This is especially needed for young trees.

Spring-Autumn · Indoors

Water regularly during growth

Water regularly while in growth

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 · Indoors

Feed with citrus plant food

Feed citrus plants a high nitrogen citrus Summer food from March to October, and a citrus Winter food November to February.

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.

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.

Winter · Outdoors

Water sparingly during dormancy

In its dormant period give very little water, keeping the soil barely moist. Dormancy is likely to be during the winter and the plant recommences growth in early to mid spring.

When a plant enters dormancy the leaves fade, go yellow and then brown. Eventually the whole plant may 'disappear' or unadorned stems may remain.
