Avocado tree

Hi Anastasia

It's a bit difficult to diagnose your tree's ailment because you haven't uploaded a picture, the age of the tree, and the circumstances surrounding the current affliction of your avo tree.

If your guacamole tree is less than one year old it might be due to infrequent watering especially during summer. Water it weekly with 3-4 gallons including the surrounding native soil if planted in the ground. If its in the pot you should water it until the H2O leaches at the bottom of the pot.

If the tree is already established, it might be due to too much chloride in your water, especially town water. Why, because the chloride accumulates at the tip of the leaves and over time it becomes toxic and starts killing the leaves starting at the tip.

How to correct this problem? The easier solution is use rainwater. There is barely any chemicals on it. If you don't have a rainwater tank, install a chemical filter in your irrigation system to filter out harmful chloride in your town water. Another solution is to overwater every month to leach out the built up chemicals around your avo tree. Some avo farmers turn on the sprinkler or drip irrigation system for 24 hours every month to leach/wash out the accumulated chemicals. You can do it weekly too by overwatering a bit everytime you do your weekly sprinkling.

Happy Gardening :-)

Under watering is just as fatal as overwatering. Check regularly for both. Avocado roots have mycorrhiza that fix nutrients and nitrogen from the air into the roots to feed the tree. So your tree is reliant on root health and fungus health. A solid soil is nowhere near as good as a porous soil that allows air into the soil. Though not too coarse.Also necessary is decaying or decayed organic material to feed the mycorhriza. A straight compost is a bit too rich. The mix needs to be balanced.
