lozza2271 starts with ... Hi can you please help identify what is going on with my avocado tree. I found an infestation of grasshoppers and have managed to get a handle on them but the avocado is suffering. Im not sure if its the grasshoppers that weakened the tree like this or if it is another problem. They ate the top leaves and then the bottom started going brown. Can you identify if there is a second issue and what I can do to try and save it. I only purchased and repotted it a few months ago. Thanks in advance.

lozza2271 says... Not sure how salt burn would be possible. We are off the coast a bit and on rainwater only.. No other plants seem to be affected. It was the same time as the grasshopper attack so Im not sure if they attacked it because it was already weak or caused it or neither. I've let it rest and moved in into shade. Looks like some new growth coming on now and another source recommended possibly too much water and maybe used old moldy coffee grinds... | About the Author lozza2271 MACLEAN,2463,NSW 7th December 2018 7:04pm #UserID: 19092 Posts: 2 View All lozza2271's Edible Fruit Trees |

Danny333 says... Hi Lozza2271, Potassium deficiency can cause leaf tip and margin burning is older leaves. I get a little of this from time to time and a bit of potassium sulfate helps clear it up. The tree may also have an underlying root problem so make sure the the soil is free draining with lots of organic matter. I’d steer clear of coffee grinds as they hold a lot of water and may suffocate the roots if used in large amounts. Keeping the tree in part shade will also help it recover. Hope this helps save your tree.

Markmelb says... I think Julie meant fertiliser salt burns non organic fertiliser you mix with water like aquasol or miracle grow cause a buildup of those salt in leave tips. Try slow release for a few years lots of worm casting compost and 200gm gypsum twice a year which helps absorb those salts ~ won't improve overnight. | About the Author Markmelb MOUNT WAVERLEY,3149,VIC 9th December 2018 7:31am #UserID: 7785 Posts: 1192 View All Markmelb's Edible Fruit Trees |
