When to fertilize leyland cypress trees?

Fertilize Leyland cypress in early spring, before new growth begins. Spread a general-purpose, fertilizer around the tree's drip line.

Accordingly, how much fertilizer does a Leyland cypress need?

To determine the amount of fertilizer needed for one tree, measure the trunk of your Leyland cypress 4 1/2 feet above the ground. If the trunk is less than 6 inches in diameter, apply up to 2 2/5 ounces of nitrogen. If the trunk is more than 6 inches in diameter, apply up to 5 ounces of nitrogen.

With allowance for this, how do I make my Leyland cypress thicker?

Leyland Cypress pruning changes once the tree reaches the desired height. At that point, annually trim the top 6 to 12 inches (15-31 cm.) below the desired height. When it regrows, it will fill in more thickly.

In like manner how do you fertilize a cypress tree?

Cypress trees growing in a regularly fertilized lawn don't generally need additional fertilizer once established. Otherwise, fertilize the tree every year or two with a balanced fertilizer or a thin layer of compost in fall. Spread a pound (454 g.) of balanced fertilizer for each inch (3 cm.)
