Why do trees lose nutrients in the summer?
A: Trees and shrubs in the Midwest often lose nutrients during the summer months which will cause them to grow more slowly and have underdeveloped root systems. Two of the most common nutrient problems that RYAN Pros see in the soil are low nitrogen levels and high pH (alkaline) levels.

Do all trees need fertilizer?
Q: Do ALL trees and shrubs need fertilizer? A: No. Not all trees are good candidates for fertilization and not all may need deep root feeding. In some cases, fertilization can cause damage to root systems, increase a tree’s susceptibility to certain pests or even cause a tree to decline faster.
Can you kill a tree with too much fertilizer?
A: Yes, you can actually kill a tree if you apply too much fertilizer or if your mix of nutrients has too much potassium and phosphorus. Too much of these elements can create an intolerable amount of sodium or soil salts. That’s one reason why evergreens planted near roads that are treated with salt in the winter may die as the salt spreads to the roots of the evergreen.

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.

Most deciduous trees and shrubs do best within a soil pH range of 5.5 to 6.8. Red maples, oaks, junipers and most conifers (pines, firs and hemlocks) prefer a pH of 5.5 to 6.0. Some conifers can tolerate higher levels; for example, yews and arborvitae prefer a pH of 6.0 to 7.0.
Can fertilizer be applied indiscriminately?
Do not apply fertilizer indiscriminately. Lawn and landscape fertilizers, if not managed properly, are a contributing source of nutrients associated with water quality degradation. Excess nitrogen can leach through soil and pollute ground water; it is also of high concern in estuarine systems.

Fertilizer applications will not correct cultural problems. A soil test is useful in determining and adjusting pH, which is important for the availability of soil nutrients. A standard soil test includes pH, phosphorus, potassium, calcium and magnesium.
Why do perennials slow down in the fall?
As the cooler temperatures of fall settle in , the growth of a perennial plant begins to slow dramatically. Blooms and bloom cycles rarely occur, and in many cases, stop entirely. In addition, plants cease trying to grow any new branches, stems or foliage as well. This all occurs as naturally, as the plants begin to prepare for the winter ahead.
What happens to perennials in winter?
Fertilizing perennial plants at this point stops that process. As winter approaches, perennials shift nearly all of their resources underground to their roots. Water and nutrients that were being used to power blooms and foliage now begin to help build strong, healthy roots.
Do perennials grow in the winter?
When perennials receive a late-season boost of energy, it actually fools them into a spring-like growth mode. One where they stop sending resources to roots, and instead attempt to grow foliage and even produce blooms. Unfortunately, that late growth then leaves perennials vulnerable to the shock and cold of winter.
Can perennials freeze out?
The result is a plant whose roots are damaged easily, and in some cases, freeze out completely.
Is fertilizing perennials bad for them?
Not only is it unnecessary, it can actually be harmful to the long-term health of perennials. In fact, in some cases, it can even lead to them perishing over winter. Fertilizing perennials as they begin to fade in the fall can lead to major problems as they prepare for winter.
