Fertilizing in the Fall
Fall can also be an excellent time to fertilize shrubs and trees. In our opinion, all trees and shrubs require fertilizer, simply because the majority of them are situated in mulch beds that use up nitrogen as they decompose. Additionally, each and every fall we rake leaves off these beds, starving plants of the nutritional requirements that decomposing leaves would traditionally release. To compensate, we suggest applying one to 3 pounds of slow-release nitrogen per 1,000 square feet of bed and cultivating lightly.
To determine the precise quantity of fertilizer you will need, calculate the square footage of one's beds and seek advice from a Certified Arborist. We prefer fertilizing trees in late September and early October to promote root development. These nutrients will still be in the soil come spring when plants begin to develop. When you have a tree or shrub that doesn't flower nicely, a dose of super phosphate will assist and promote flower development. Nevertheless, when the plant isn't situated in the correct spot, all of the super phosphate in the world will not make it flower.
