A copper based clean up spray is the most effective way of controlling leaf curl. When bud burst in the spring, spray in autumn and winter using a copper fungicide and oil. Compost as this will encourage the growth of the fungus, and collect up any leaves that fall and burn or dispose of.
Copper fungicides are available from most garden centres and garden shops and can be purchased as a spray or as an aerosol. The spray should be applied to the affected area as soon as possible after the bud has burst. It is best to apply the spray in the morning and leave it on for a few hours to allow the copper to penetrate the leaf tissue.
This will kill any fungus that may be growing on the leaves. If you have any doubts about the safety of this product, please contact your local garden centre or garden shop and they will be able to advise you on whether or not the product is suitable for your area.

Why are my lemon tree leaves curling up?
The under-watering can cause the tree to Curl. If you have a healthy tree, you should not see any signs of disease. However, if your tree is in poor condition, it may not be able to produce fruit. You can check the condition of your trees by looking at the foliage.
If the leaves are yellow or green, the tree may be in good condition. But if they are brown or black, then it’s time to take action to prevent further damage.
What deficiency causes curling of leaves?
Calcium is needed by plants to produce new growing points and root tips. Symptoms of deficiency include new foliage, buds and roots. Leaf curl is caused by low levels of calcium in the plant’s diet. Leaves curl downward and turn brown. Leaves turn yellowish-green and die.
Symptoms can be mild or severe depending on the level of deficiency. This is called “leaf curl” and is a sign of low calcium levels.
How often should you water citrus trees?
Newly planted young citrus trees need to be deeply water about once or twice per week for the majority of the year. When the weather is hot and windy, water is more likely to be found in sandy soils. During the hot summer months, reduce the frequencies to weekly in clay soils. Citrus trees should be planted in a well-drained, sandy soil with good drainage.
If the soil is not well drained, the trees will not be able to root properly and will be more susceptible to disease and insect damage. This is a good starting point for citrus tree root development. It is important to water the tree regularly, especially in the spring and summer, to prevent root rot and other problems that can result from too little water.
Citrus tree roots are very sensitive to soil moisture, so watering too often can cause the roots to dry out and become brittle. In addition, too much water can damage the root system, which is why it is so important not to over-water a tree. A tree that has not been watered for a long period of time may not have the necessary root structure to withstand the stresses of a hot, dry climate.

leaves. The leaves on the tree will begin to droop like they aren’t strong enough to support the leaf. New leaves appear to be forming but die off quickly. You can see this in the picture above. The leaves are starting to droop. This is a good sign that the root system is weak and needs to be re-established.
If the roots are weak, they will not be able to hold the weight of the new growth and the plant will die. In this case, you will need to cut back on the amount of water you are giving your plant to make sure it is getting the nutrients it needs.
It is important to note that this is not the same as overwatering, which is when you give too much water to a plant and it over-waters and dies. Over-watered plants are more susceptible to root rot and other problems that can be caused by too little water.

Pruning is the process of cutting off the branches and twigs that are no longer needed. It’s important to remember that you don’t have to cut off every branch or twig, just the ones that aren’t needed anymore.
