A “complete” fertilizer — one that supplies the macronutrients nitrogen (N), phosphorus (P), and potassium (K) — is often recommended. A fertilizer analysis of 10-8-15 means the fertilizer has 10 percent nitrogen, 8 percent phosphorous, and 15 percent potassium.
Evergreens grow best in acid soils and some nutrients may be unavailable to the tree if the soil is too alkaline. Early spring, April, is the best time to fertilize, before new growth begins. Fertilizer can be applied until mid-July, but any later may cause late growth that would be damaged by frost.
Research in woody plant nutrition has shown however that nitrogen is the element that yields the greatest growth response in trees and shrubs. For this reason, high nitrogen fertilizers with N-P-K ratios of 4-1-1, 3-1-1 or 3-1-2 are generally recommended for feeding established woody plants.
Evergreens. I fertilize evergreens in the early spring. I use one pound of 10-10-10 per inch of trunk diameter. If the diameter is over six inches, I use two pounds of 10-10-10 per inch of trunk diameter.
Fertilizing about 2-3 times a season is the norm for evergreens, however, applying nutrients later on in the season, especially after about mid-July is detrimental.
You gear up for taking care of your lawn in the early spring but did you know that fall is a great time to take that same caring approach by fertilizing your evergreens, trees and shrubs?
Feeding your evergreen trees can help them be what evergreens should be: gorgeous, strong, and vibrantly coloured. Nourish them all season long with Miracle-Gro® Evergreen Plant Food Spikes 12-6-12. These spikes deliver essential nutrients above the soil, and feed beneficial microbes below the soil, too.
Damage due to excessive fertilizer or rock salt applications generally appears as marginal leaf browning (brown edges or leaf tips) or leaf scorch on deciduous plants (they drop their leaves at the end of the season). On evergreen trees and shrubs needle tips will turn brown and become brittle.
A granular, slow-release fertilizer is the best option for fertilizing pine trees. Several formulations designed for evergreens are available. An organic granular fertilizer such as Espoma Evergreen-Tone 4-3-4 will provide a slow-release, well-balanced supply of nutrients in addition to beneficial soil microbes.
Recommended for root development of all types of plants. Normally is selected for feeding trees and landscaping plantings. Recommended for root development of all types of plants.
Epsom salt can improve the blooms of flowering and green shrubs, especially evergreens, azaleas and rhododendrons. Work in one tablespoon of Ultra Epsom Salt per nine square feet of bush into the soil, over the root zone, which allows the shrubs to absorb the nutritional benefits.
For example, adding coffee grounds or organic matter around your evergreens' soil is a good place to start if you need to increase your soil's acidity.
Trees and shrubs, especially newly planted ones and evergreens, need ample water in their root systems as they go into winter. Continue to water as long as you can.
Winter's dryness leads to leaves lacking water when the roots aren't able to take up moisture and replace what's missing. Worst case scenario, the evergreen will drop needles and branches will die. You can try to avoid winter burn by keeping the plant adequately watered as winter approaches.
If you are looking to nourish your pine tree through and through, the Miracle Gro'N Shake feed is an excellent option.
Since most of a tree's roots can be found in the top foot of soil, broadcast the fertilizer evenly with a rotary or drop-type spreader over the root zone area to fertilize the tree. Water after application to make the nutrients available to the roots.
Make sure that you water your trees regularly in order to maintain moist soil. These evergreens don't need much fertilizer just plenty of sunshine and water. However, if you choose to fertilize these trees, you can use a tablespoon of balanced tree fertilizer and sprinkle it on top of the ground around each tree.
Trees and shrubs that should not be fertilized include newly planted specimens and those with severe root damage from recent trenching or construction. The root systems of these plants need to re-establish before fertilizers are applied. Older, established trees do not need to be fertilized every year.
MG is so strong that if used incorrectly, the fertilizer will actually burn the leaves and roots of your plants (you may have already experienced this). Imagine what it's doing to the healthy bacteria, fungi and other soil microbes that are working so hard to provide the nutrients your plants need.

The main issue with this fertilizer is that it contains a lot of nitrogen. This component comes from synthetic materials, which produce chemicals potentially harmful to the soil and the plants that aren't listed as active ingredients.
