Citrus

Citrus trees have glossy green foliage year round, sweetly scented white flowers and beautiful colourful edible fruit. Lemons, Limes, Oranges, Mandarins, Grapefruits and Cumquats are the most popular forms of citrus.

There are a number of varieties of citrus which are available to purchase that have been grafted onto dwarfing rootstocks, this makes them more suited to container growing or smaller gardens.

Citrus are also available as multi grafts ie. two varieties of citrus grafted onto the one rootstock – this also enables multiple citrus trees to be grown in the one pot or smaller gardens.

USES:      
Citrus are mainly ornamental and practical plants for the garden and are commonly used as both a feature and for their produce.

PLANTING TIPS:   
Prefer an open sunny position with excellent drainage. Happily grown in pots and containers.

SOIL TYPE:
Open free draining soils are best, clay soils are also ok, but ensure you raise the garden bed up to improve drainage, add gypsum and plenty of organic matter to the soil to improve drainage. Soil pH levels should be neutral to acidic. Citrus are shallow rooted trees and therefore require regular watering and will benefit from a thick layer of organic mulch – avoid too much mulch around the trunk to avoid collar rot.

ASPECT: 
Citrus prefer to grow in a full sun position, however can grow well in sheltered part shade, but often produce more foliage and less flowers and therefore less fruit. Protect your citrus from frost and hot dry winds, especially while young. Citrus are not deep rooted and therefore do require regular deep watering in the warmer months and whilst fruiting.

PRUNING: 
Citrus can be pruned quite heavily if required. Best way is to pick the fruit by taking a small amount of stem with the fruit, however if you need to improve shape or remove damaged/pest affected foliage, the plant will recover quite well and re-shoot on older branches. Citrus can also be pruned and shaped into espaliers and standards very successfully.

WATER REQUIREMENTS: 
It is always advisable to water citrus well when they are setting fruit and throughout the fruit growing and ripening stages. If plants dry out it often results in fruit drop and the citrus is less juicy and thick skinned.

FEEDING:
Citrus love food. A variety of different fertilisers can be used including organic manures (cow, horse or chicken) or the popular inorganic fertilisers. Citrus should be fed 3-4 times per year and if growing in pots/containers it is often recommended to feed your citrus every 6-8 weeks. We suggest Richgro's Fruit & Citrus Premium PLUS

PESTS & PROBLEMS:
Citrus Leaf Miner, Scale and Sooty Mould - Treat with a Pest Oil / White Oil. We suggest Yates Pest Oil and Yates White Oil
Ants - Usually occur as a direct result of Sooty Mould. See above for Sooty Mould treatment and once it is cleared, the Ants should disappear also.
Aphids - Application of Pyrethrum or Confidor will eradicate them or can simply be squashed with your fingers. We suggest Richgro's Natural Pyrethrum Insecticide and Yates Confidor
Citrus Gall Wasp (lumps, bumps and swellings) - Prune off any damaged or disfigured foliage, preferably before August when the new wasp will emerge and be ready to lay eggs and start the cycle again. We suggest Go Natural Insect Traps.

Please read and follow all instructions before using any form of natural or chemical pesticides.

MINERAL DEFICIENCIES: 
Yellowing leaves - especially of new growth and with the veins standing out in green is a sure indication of Iron Deficiency. An application of Iron Chelates sprayed over the foliage and/or watered into the root zone will correct the imbalance.

The use of a complete Fruit & Citrus Food should solve any other possible deficiencies.
