Why Is My Olive Tree Shedding Yellow Leaves

When established water deeply and less frequently.
Why is my olive tree shedding yellow leaves. A young tree needs lots of water at first. This should not be a problem in sandier soils. Trees suffering from a nitrogen deficiency have yellow tinged leaves and poor growth. If the trees get too much water the leaves may yellow and drop.
Yellow leaves are usually indicative of under or over watering. If the leaves are yellow with brown spots your tree may be infected with olive peacock spot. Heat and drought stress will cause the tree to lose leaves that it cannot support with the available soil moisture. Good drainage is essential.
If falling leaves are well distributed throughout the tree and result in a general thinning of the leaves the problem is not serious. Olive trees require plenty of bright light. Keeping your potted olive tree in a sunny window will help provide adequate light. Symptoms of deficiency will often disappear by early summer.
Olive trees have few pest problems but one that can cause excessive leaf drop and stunting of growth are nematodes. Transferring it to a sunny porch or patio during the summer may help enhance its growth and appearance. Trees will often set more leaves in the spring than they can support during the summer. Nitrogen is a macronutrient easily leached from the soil by water.
This deficiency is most prevalent in heavy soils during cold and wet weather when nitrogen is less available. Nutritional deficiency nitrogen is most frequently lacking nutrient in olive trees. Top dressing your olive tree with manure or a commercially available high nitrogen fertiliser once a year in the spring can eliminate the yellowing of your olive leaves. Plants with nitrogen deficiency show a yellowing of the leaves from bottom to top.
The usual nematode is the root knot nematode the same one that damages many vegetables fruit trees ornamental trees and shrubs.
