What are the disadvantages of natural fertilizers?
A disadvantage of natural fertilizers is that usually the concentration of nitrogen, phosphorus and potassium are lower. Therefore, a greater amount of a natural fertilizer must be applied to provide the same amount of nutrients that can be obtained with a lesser quantity from a synthetic nutrient source.
What is the difference between slow release and fast release fertilizer?
Two kinds of fertilizers are available: fast-release and slow-release. Fast-release or water-soluble fertilizers are less expensive than slow-release products, which release nitrogen over an extended period; however, the nutrients in a fast-release fertilizer may leach quickly through the soil.
How do plants produce food?
Plants produce their own food in the form of sugars through photosynthesis. The minerals or nutrients supplied by fertilizer provide the ingredients needed for photosynthesis and growth. When minerals are lacking or absent in the soil, fertilizer can be added to maintain an adequate supply.

For example, a 15-5-10 fertilizer contains 15% nitrogen. Fifteen into 100 equals 6.6, therefore, apply 6.6 (rounded off to 6.5) pounds of this fertilizer per 1000 square feet. Twice as much, or 13 pounds, would be required to provide two pounds of nitrogen per 1000 square feet.
Why do leaves have dead tissue?
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.
What is the pH of NH soil?
Unaltered NH soils commonly range in pH from 4.5 to 5.5. A standard soil test will determine your soil pH level and recommend the amendments needed to raise or lower pH to provide the optimum environment for trees and shrubs growing there.
Why You Should Use Shrub Fertilizer
Plant fertilizers contain the essential elements for shrub nutrition. Providing a balanced amount of nutrients helps shrubs grow and thrive. In addition, fertilizing shrubs helps ensure that the plant’s root system is robust and healthy, making them resistant to pests.

Nutrients in Shrub Fertilizer
The three essential nutrients for shrubs are nitrogen, phosphorus, and potassium. Nitrogen is the vital nutrient that shrubs need for fast growth. Potassium and phosphorus are crucial for flowering shrubs. But shrub fertilizers may also contain micronutrients like calcium, copper, zinc, magnesium, iron, molybdenum, sulfur, and boron.
Recommended Evergreen Shrub Fertilizer
Evergreen shrubs tend to require fertilizer that contains more nitrogen than potassium or phosphorus. This is because many evergreen coniferous shrubs have fast growth and require nitrogen to develop lush, green foliage.
Recommended Flowering Shrub Fertilizer
The best fertilizer for flowering shrubs should have a higher proportion of potassium to phosphorus and nitrogen. This is because blooming takes a lot of energy from the shrub.

Do conifers need to be staked?
Conifers generally don’t require staking, but there are three exceptions: Those used in very windy locations may need to be staked, but for no more than a year, long enough for anchor roots to develop sufficiently to support the plants. Staking is also beneficial for weeping or pendulous plants that are not yet self-supporting. Finally, if you want to espalier plants, they should be supported.
What is the best conifer for shady areas?
Some species naturally grow in the understory of large canopy trees. These do quite well in places of low light. Chamaecyparis, Taxus and Tsuga are the best conifer species for shady locations. Remember to consider growth rate when placing your conifer; fast growing selections will need space to expand.
What is a conifer?
Conifers are woody plants, which means that they have stems and trunks of wood, which are covered with bark. They have woody stems even if they are ground covers or tiny miniatures that grow a fraction of an inch a year. Most of us think of trees when we hear ‘woody plants’ but there are thousands of shrubs, groundcovers and vines that are included in the category. Growing and caring for conifers and other woody plants is generally the same.
How long does it take for a golden conifer to burn?
Some of the golden cultivars will burn in full sun until established, which can take 2-3 summers. A few never burn in full sun.

What is the problem with B&B conifers?
B&B conifers have an unique set of issues: The soil is often clay, and the clay ball often buries the root flare. There is often much more root trauma involved with digging and preparing these trees, which means more transplant shock and a greater need for supplemental irrigation. Adventitious roots grow into the soil above the flare.
How to get rid of woody roots in pot?
You can use pebbles or other inorganic materials to increase drainage in the mound, if necessary. Remove any excess soil above the root flare, then loosen the roots, especially roots that wind around the inside of the pot and especially girdling roots near the trunk.
How are woody plants grown?
Woody plants are grown in one of two ways: in containers or the field. Container-grown plants are much more likely to be root-bound than those that are field grown, however their entire ‘history’ is evident in the container, and it is relatively easy to get a look at the roots.
Where is the flare on a conifer?
It’s critical for a conifer’s root flare (the point at which the roots begin to “flare out” from the trunk) to be visible at the soil surface. Many woody plants are buried far too deeply. The plant must be ‘excavated’ so that the flare is visible.
