We have two olive trees in pots. One tree has sections where the leaves are turning brown and dry. The branches are dry and dead too. This is happening to both old and new leaves. The tree itself is growing many new healthy leaves too.

It is difficult to know what is happening to your trees without a little more information. There is an insect which does attack olive trees called an Olive Lace Bug. This insect feeds on the underside of the leaf sucking sap and causing yellow mottling of the leaves which then go brown and fall. This insect is active in summer so the leaves that have gone brown and fallen from your trees could have been last year's damage. If it is this insect that has caused the damage, it is important to detect this insect early this year and control it before it does any more damage. Those branches that are dying back could be pruned off to encourage new growth. You could also apply a fertiliser such as Yates Thrive Natural Citrus & Fruit Pelletised Plant Food. It's enriched with Dynamic Lifter and has added nitrogen, phosphorus and potassium to give your fruiting plants the right balance of nutrients for their growing needs. Hopefully your trees will improve. If the problem continues, you could always send us a photo which will help us to diagnose further. Good luck
