 fact sheets - Citrus
CITRUS PROBLEMS

Citrus are an important part in our diet. Sometimes we tend to throw away a crop because we think it is unpalatable.

CITRUS WITH A HINT OF GREEN ON THE OUTSIDE.
The greenish tinge can caused in two ways:-
Temperature is one controlling reason in the appearance of citrus.Warm days and cool nights are necessary for the fruit to turn a bright colour. But now and then the nights remain warm, depriving the crop of the cool temperatures that contribute to the orange or yellow colour. As the fruit ripens, it remains slightly green on the outside, while developing perfectly on the inside.
The second influence is a natural process called "regreening." In the spring, trees have an extra supply of chlorophyll to help form the new fruit. The trees can maintain both ripe fruit and blossoms at the same time. As the chlorophyll spurts up to the new growth, it is also absorbed by the skin of the ripe fruit, giving it an extra dose of green. Despite its greenish skin, the developed fruit is still palatable and delicious on the inside.

HOW TO IMPROVE YOUR FRUIT TREES

There is nothing more enjoyable than going out into your garden and picking fresh home grown fruit. It is important for us to have a healthy body and the food we put in our mouths must be nourishing and rich in minerals.

FEEDING CITRUS TREES
Like most plants, citrus trees need foods which contain essential nutrients for green healthy foliage and large juicy fruit. It is recommended for use on lemons, oranges, grapefruit, mandarins, limes and cumquats etc, to use a Fruit & Citus Food. Spread the fertiliser 30 cm away from the trunk covering the whole area outwards to the edge of the foliage drip line (where the foliage ends). Water the fertiliser immediately into the ground after application.
NEVER apply more than is recommended. If you want to play safe, apply half the recommended rate and repeat three to four weeks later.

HOW TO MAKE CITRUS FRUIT SWEETER
Mix 20 grams of Sulphate of Potash in 9 litres of water, stir in well and apply over 2 square metres around the foliage area of the tree.

THICK SKIN ON CITRUS FRUIT
SYMPTOMS
When you have thick skin on the fruit of a healthy citrus tree it is usually an indication of a nutritional imbalance. This is normally caused by too much nitrogen and not enough potash. This is a common problem where animal manure has been completely substituted for a complete fertilizer.
RECTIFICATION
Apply 250g of sulphate of potash immediately and a further 250g with 1kg of super-phosphate in autumn. Then next spring apply 1kg of complete fertilizer.

IRON DEFICIENCIES
Iron deficiencies are quite common in our lime rich soils, therefore the term 'lime induced chlorosis'. Foliage applications of iron can help as do applications of iron in the chelate form. For Iron chlorosis in Citrus plants use Iron Chelates.
There has been successes in using sulphate of iron by placing the fertiliser under individual drippers where there is a drip irrigation system in place.
Where shallow soil exists over limestone, further soil management is essential. Little cultivation to the soil around the citrus will allow surface mulch to build up and develop into a rich compost is advisable. This permits the plants roots to grow nearer the surface where the pH is lower. Applications of organic MULCHES
will help improve the soil texture and encourage worms to come into the area
Controlled watering is very important, to prevent the soil from becoming water-logged.
For more information see Mulching and Water Saving..

ZINC DEFICIENCIES
Zinc is not very mobile in the plant so a thorough foliage cover spray is essential to enhance fruit set. Citrus trees suffering deficiency in zinc will certainly follow with a decline in the yield. Zinc sprays should be applied prior to fruit set for maximum benefit.
