Hi, last year our lemon tree was full of leaves but few flowers and lemons. This year it is absolutely covered in flowers but many of the leaves have fallen off. Should we reduce the number of flowers and why are the leaves dropping. Thanks.

Hi Cotsilinis, you don't say whether your tree is established or newly planted, also whether it is in the garden or a pot. The main reason citrus will drop their leaves is because the are stressed, and some of the causes of this are below. 

• Unseasonal weather and temperature fluctuations of hot to cold, or frost. Citrus are a sub tropical fruit tree and can withstand some frost once established.
• Wind, they really don't like wind, provide some sort of protection if it is a windy site.
• The tree has dried out or got too wet. Over watering or under watering are also possible causes, ensure it is planted in a well drained soil or potting mix, adjust watering to the weather conditions, especially if planted in a pot.
• Over feeding or under feeding. If too much fertiliser is applied it can burn the roots and plants will drop their leaves. If the tree needs feeding it may also drop its leaves.
• If it is in a pot and root bound it can drop its leaves, it needs repotting into a bigger pot.
• Is there any sign of insects or disease? They can get a root rot disorder if drainage is poor.

Applying Tui Seaweed Plant Tonic every week at a rate of 70-100ml per 9L watering can until the tree recovers. Move the tree if you think it is in the wrong position with too much wind and not getting enough sun or the soil is poorly drained. It is natural for citrus to shed flowers and fruit it is it too much for the tree to support, don't be surprised if the flowers or small fruit fall off, this is natural. As for the leaves, the tree will bounce back, you will find it will come back into leaf. Lianne.
