How to Fertilize Mulberry Trees
Fertilizing mulberry trees is a process that should be done on an annual basis. The best time to fertilize mulberry trees is in the early spring or late winter before new growth starts.
Step 1
The best fertilizer for mulberry trees is a low-nitrogen, time-released, granular fertilizer, that is specifically made for fruit trees. You should sprinkle the fertilizer around the base of the plant in early spring just as the weather starts to warm up or when you see new leaf buds emerge.
You’ll want to apply the appropriate amount of fertilizer around the drip line of your mulberry tree’s trunk, and then gently rake the time-released fertilizer into the top layer of soil.
Step 2
After you apply the fertilizer, water them with at least 2 inches of water so some of the fertilizer can seep deeper down into their roots to get the plant going for springtime.
Step 3
Mulberry trees start to slow their growth in the fall and winter. Apply more fertilizer halfway through the growing season, but be mindful that you don’t apply too much fertilizer since mulberry trees don’t take up as many nutrients towards the end of the season.
Mulberry Tree Problems
Why Are My Mulberry Leaves Turning Yellow
Mulberry leaves are often yellow when they are experiencing a nitrogen deficiency. Nitrogen is an essential nutrient in plant growth and reproduction that tends to be lacking in most soils. To rectify a nitrogen deficiency, it must come from other sources – typically fertilizer.
Why Are My Mulberry Leaves Turning Brown
If your mulberry tree is turning brown your tree could be suffering from bacterial blight, Leaf Spot, or Canker disease. It might also be a problem with too much water, fertilizer, or excess sun exposure early in your mulberry tree’s life.
Why Is My Mulberry Tree Losing Leaves
Mulberry trees can lose their leaves from problems such as bacterial leaf scorch, leaf spot, and nutrient deficiencies. Bacterial Leaf Scorch causes the leaves on newly emerging shoots to die prematurely with a distorted venation pattern that’s lighter in comparison to the surrounding healthy leaf tissue. And these symptoms are usually more dramatic when mulberry trees are grown in damp wet conditions
Lack of fertilizer is another common cause of leaf loss in mulberries because they have heavy feeding requirements that might not be adequately satisfied by endemic soil nutrients.
My Mulberry Tree Leaves Are Curling
Mulberry tree leaves can curl for a variety of reasons, one of which is if there is a spider mite or aphid infestation.
Spider mites feed on the sap that moves through the leaf which will cause it to curl and wither away.
Aphids can also remove all the sap from the leaves causing them to curl down due to a lack of internal pressure.
However, in some cases, curling leaves can also be related to chemicals such as herbicides or excess fertilization.
Why Is My Mulberry Tree Not Fruiting
A mulberry tree that is not fully mature may not yet be ready to fruit. Some trees are seen to produce their first crop at 2 years old, whereas it can take up to 5 or 6 years for other varieties.
The best way to tell would be to compare the age of your tree with similar trees in the area and see when they began fruiting.
Why Are My Mulberries So Small
A common cause of small mulberries is that your trees are getting too much nitrogen and not enough phosphorus and potassium. The plant typically responds to excess nitrogen by increasing the size of its leaves which leads to a lush green tree with lots of smaller fruits.
