Although lawns benefit greatly from a late fall fertilizer, trees and shrubs do not. The fertilizer, which is mainly nitrogen, encourages new shoot growth in woody plants. Encouraging new growth at the end of the growing season may allow a greater chance of winter damage. Late fall pruning is also not recommended, unless the branches are damaged or my break to a heavy snow load. Grass clippings do not make good mulch for roses.

organic or time-release fertilizer balanced in all three elements: nitrogen, phosphorus and potassium (N-P-K). We use Nature's Turf 15-1-6, Turf Saver 4-3-4 and Tree Saver 3-0-20 from John Deere's natural line.

It is a good idea to fertilize your lawn at least 4 times a year. The first application should be in early spring and your schedule should end in late fall. Shrubs only need to be fertilized twice a year to keep them healthy. Applications should be in early spring and late fall.

We recommend using Jirdon’s Tree and Shrub fertilizer. It is formulated specifically for trees and shrubs in the Rocky Mountain region. You should apply a light application around May 15, June 15, and July 31. If you are fertilizing less often shoot for May 15 and July 15. You don’t want to fertilize after the first part of August. You don’t want to push too much new growth late in the season.

Fall fertilizer is considered by many turf experts to be the most important feeding of the year. By feeding in the fall, the root system is strengthened and builds a reserve of carbohydrates. This will help the grass to survive the cold winter months and help get your lawn off to a fast start in the spring, which builds a healthier, thicker lawn.

This is a tough one to answer, because fertilization is so tremendously tied to water quality, potting medium, temperature, light and a variety of other factors. However, if you just have a few plants, and don't want to fuss around a lot learning about the intricacies of water and fertilizer, I'd simply suggest you get any reasonably balanced 'orchid' fertilizer, that is low in urea, and use it at approximately 1/4 to1/2 the label strength every other watering.

Trees often require fertilization at some point in their life span. Remember, most tree’s natural environment is the forest. There nutrients are continually recycled as leaves and other plant, and even animal material, fall and decompose on the forest floor. When you put a tree in a landscape setting it is usually deprived of these nutrients. One thing you can do is try to recreate the tree’s natural environment by providing mulch rings. See Mulches.

Injections made in the fall are limited by how long the tree will translocate (absorb chemicals). This will differ for each part of the country, however it is usually a lot earlier than people think. As the tree starts shutting down for the year, the cambial zone starts to dry up. Injections made after this occurs may fail to control that year, as the cambial zone will not retain the chemical. You may also see some phytotoxicity by injecting late in the season that would otherwise not occur.

Phosphorus from fertilizers runs off lawns and ends up in area wetlands, ponds, and lakes where it promotes algae growth. Algae can damage or kill the water body's eco-system. The make-up of all fertilizers is indicated by a series of three numbers on the package. The middle number indicates the amount of phosphorus the fertilizer contains. Look for a middle number of "0" to be sure you are buying a phosphorus-free fertilizer.

A: It really depends on the type of fertilizer being used. Water soluble (Like Miracle Grow) can be used anytime until the end of July. Spikes or slow release granulars are best applied early spring. Any fertilizer applied past July should be low nitrogen to promote root growth as opposed to foliage growth.

With so many climates and so many grasses used in Alabama, it is difficult to give blanket recommendations. In order to properly fertilize your lawn, it is important to know what kind of grass you have (or wish to have). If you need help identifiying the grass in your lawn, contact your local Extension office. There are some basic rules of thumb to fertilizing a lawn. For warm season grasses (the majority of grassed grown statewide, including bermudagrass, centipedegrasss, St.

Citrus are usually fertilized three times a year - Valentine's Day, Memorial Day and Labor Day. newly planted trees do not need fertilizer the first 1-2 years. Use Ammonium Sulfate, Ammonium Phosphate or Citrus Food fertilizer. The amount of fertilizer need per year depends on the age, the size, and the type of tree. For example, a medium-sized adult tree 5-6 years after planting needs 6.2 pounds of Ammonium Sulfate per year (split into three applications).

Thrice is nice. That's the recommendation on a bag of citrus fertilizer from Arizona's Best. And it makes sense if you think about it. First feeding comes near the end of winter which means February while the tree is somewhat dormant possibly looking a little under the weather because of a number of unexpected freezing nights so the leaves look a bit dried and discolored.

Cool season grasses such as bluegrass, fescue and ryegrass should be fed once in the spring and two or three times in the fall during the months of September, October, November and December. Warm season grasses such as zoysia, (which turns a tan color from October – April) should be fed one or two times per year from May-August. We recommend using Merrifield Premium and Merrifield Select Lawn Foods, which have been custom blended for the conditions in this area.

BOB: While there are a few trees (Oaks and "fleshy rooted" trees) that should only be dug in the spring, most plants today are containerized or balled-and-burlapped (B+B) and can be planted anytime of the year. [More about shrub planting and tree planting]
