Types of Fertilizers for Italian Cypress Trees

There are different types of fertilizers that can be applied to Italian Cypress trees; however, it is important to understand how these fertilizers work before deciding on which to buy and not buy. The knowledge of how fertilizer works would help you know which fertilizer is best for the Italian cypress tree and when to apply it. Here is it:

1) Slow-release fertilizer

Slow-release fertilizer is one of the best choices for the Italian Cypress. These fertilizer types release nutrients slowly into the soil over a long period. The frequency of usage of this slow-release fertilizer is usually low, about twice a year because of its longevity in the soil. Examples of slow-release fertilizers are compost, vermicompost, animal manure, and organic wastes.

One of the benefits of applying a slow-release fertilizer to Italian Cypress trees is that these fertilizers won’t overwhelm the tree plant and will provide nutrition gradually over time. It enhances a lush and healthy landscape. Slow-release fertilizers are applied using the top dressing or band placement method of fertilizer application.

A recommended dosage of this fertilizer is applied near the root zone of the Italian cypress tree. After application, it is covered with the topsoil. It is advisable to water Italian cypress trees weekly, starting when they go into their growth spurt, and during the fall, before the trees go dormant. This helps to activate the fertilizer for nutrient release.

2) NPK Fertilizers

The NPK fertilizers are specially formulated fertilizers that contain Nitrogen, Phosphorus, and Potassium in different proportions to meet and correct nutrient deficiency. These fertilizers are rapid in action and do not last long in the soil like slow-release fertilizers. NPK fertilizers are available in different formulations depending on the needs of the plant

A balanced NPK fertilizer, like 10:10:10 or 15:15:15, is best for the Italian cypress trees during the vegetative growth stage. This fertilizer supplies nitrogen, phosphorus, and potassium in equal proportion. This NPK fertilizer can be applied in a ring formed around the Italian cypress trees. The fertilizer granules are poured into the ring before covering it with the top soil.

The difference between the NPK fertilizers and slow-release fertilizer is the mode of action. NPK fertilizer gives an instant response to the nutritional needs of Italian cypress trees; they are fast-releasing and do not stay in the soil for a longer period like slow-release fertilizers.
