What are the nutrients that trees need in the Southeast?
Trees in the Southeast region are a little different. They can be lacking the macro-nutrients mentioned above, but they’re also often faced with a micro-nutrient deficiency, meaning essentials like potassium, magnesium, manganese or boron are in short supply. Scientists at The Davey Institute created Arbor Green Xtra plus B to address that. It combines all the nutrients—both macro and micro—that Southern trees need to look and grow their best.

Young shrubs and trees in landscape beds often benefit from fertilization. Fertilizers can stimulate growth and improve the color and appearance of plants. The three primary nutrients contained in most fertilizers are nitrogen, phosphorus and potassium.
What are the deficiencies in landscape plants?
Besides nitrogen, phosphorus and potassium, minor nutrients such as iron, magnesium or manganese are sometimes deficient in landscape plants. These deficiencies can be diagnosed by plant symptoms, soil tests and/or leaf tissue analyses. Problems caused by planting too deep, drought, over-watering, disease or mechanical damage may cause symptoms similar to nutrient deficiencies. Fertilizer applications will not correct cultural problems.
Why is nitrogen important for plants?
Nitrogen is the fertilizer nutrient that plants use in the largest amount, and fertilizing with nitrogen causes plants to green up and increase growth rate. Established plants that are putting on very little new growth each year or whose leaves are small and light in color may be showing signs of nitrogen deficiency. Unfortunately, there is no lab test for nitrogen because it has many forms and can be converted or lost quickly in the soil environment. Nitrogen recommendations are based on research and experience with how plants respond to added nitrogen.
How to recycle organic matter?
It is estimated that leaves which fall from a tree and decompose in place recycle at least a pound of nitrogen per 1000 square feet of surface area. You can allow several inches of leaves to naturally accumulate in the fall (and serve as mulch) in shrub beds and tree areas, if there are not ground cover plants underneath. If you prefer to rake up leaves and trimmings, shred and compost them and reapply the finished compost to the planted areas.
What causes dead tissue on leaves?
The amount should be determined by a soil test. Areas of dead tissue along leaf edges may be a symptom of potassium deficiency (but may be caused by drought or other factors). Besides nitrogen, phosphorus and potassium, minor nutrients such as iron, magnesium or manganese are sometimes deficient in landscape plants.
What happens when phosphorus is carried into freshwater?
In addition, the effects of diseases, insects or environmental stresses may be more severe on heavily-fertilized plants.
How does phosphorus affect water quality?
Excess phosphorus in the environment may be carried by stormwater runoff into nearby surface waters, where it can contribute to water quality degradation. Potassium is generally low in our soils, so can be included in routine annual fertilization along with nitrogen. The amount should be determined by a soil test.
How to help perennials survive winter?
The same logic applies to your shrubs, trees and perennials: give them a nutritional boost before winter to help them bounce back vigorously in the spring. Fertilize your plants, shrubs, trees and lawn to stimulate root growth, which will help your plants survive the winter and recover earlier in the springs.
Why is nitrogen important for plants?
Nitrogen is important because it promotes foliage growth. “P” stands for phosphorous, and it’s the chemical that triggers root growth in plants. While the cool fall temperatures make it look like your plants are dead or dormant, there is still a lot going on under the ground —mainly root growth. Fertilizer high in phosphorus promotes strong, ...

Not all shrubs, bushes and trees need to be fertilized , but if they have undersized or pale green leaves, or are showing dead branch tips, dieback or insect damage then they probably do. Newly planted items need to establish roots first, as do plants showing damage from being transplanted or from construction, for example. Also, older, more established trees and bushes don’t need to be fertilized every year. Remember, in these larger specimens, the roots can spread out, so make sure the entire surface area is fertilized, out to 1.5X the diameter of the plant’s branches.
