Treating pest is an all organic method to handle the olive fruit fly.
Here are our tips for preventing and treating Olive Tree Pests & Diseases.
An Ounce Of Prevention Is Worth A Pound Of Cure
While this is a bit of an old wive’s tale, it is true that prevention is better than a cure when it comes to pest or disease. If your Olive Tree picks up a nasty pest, you could spend a lot of time (and money) trying to remove all traces. So if your plants in good condition, you should be able to avoid any major problems. To do this, we recommend you follow the tips:
1) Keep your Olive Tree well fed
This isn’t essential but will help prevent disease. Just add a bit of liquid feed or mix in some fish blood and bone to the soil twice a year and there will be plenty of nutrients for you Olive Tree to fight of disease.
2) Olive trees Do Not like wet feet
To keep an Olive Tree healthy, it does not need to have moist soil. Instead, dig a couple of inches into the soil to see if the soil is moist enough. If it’s dry, give it a good water. Just make sure there is enough drainage for the excess water to escape.
3) Prune your olive tree
It is very important to prune. Pinching out young shoots can encourage growth and help the Olive tree to remain strong and healthy. In the late Spring and early Summer, make sure that branches are thinned out to allow light into the centre of the Olive tree, enough so a bird can fly through.
4) Give it some sunshine
Olive Trees love sunlight. The more you can give them, the better! This will not only keep your tree healthy, this will also keep the foliage dry, which will help prevent mildews and fungus building up.
5) Act quickly
If you do spot something, look it up or contact us, seek advice from a local knowledgable source. You’ll see some common issues below but if you’re not sure, it’s best to ask someone.
6) Remove diseased fruit
California is ideal for growing olives. Some areas in the cooler climates near the coastal regions of Northern California, can sometimes attract the olive fruit fly. If you spot any damaged fruit, you should remove the offending fruit and properly discard it. Keeping your trees at a manageable height will help with your overall harvesting and crop management.
