I don't think there's one "correct" answer to this one. The general rule of thumb is for Paphiopedilums to fertilize every 1 to 2 weeks at 1/2 the strength of the recommended dosage for other orchids such as Cattleya's and Phals. I haven't had any problems following that guideline and my plants grow quickly and strongly. For Phragmipediums I've ended up cutting back to 1/4 strength doses at most, as I've been developing a lot of fertilizer burn on the leaf tips recently.

Again, this is specific to the plant and the environment but generally, during the spring, summer, and fall (the growing season) use a house plant fertilizer per package directions. An excellent strength is a fertilizer comprised of a 9-6-9 ratio.

Granular fertilizers are more persistent in the soil; they are absorbed more slowly and last longer. They can be incorporated into the soil at planting or they can also be broadcast onto the surface of the soil of existing plants. Super phosphate, frequently lacking in western soils, is essential for plentiful flowers and strong root growth. Grow Power is an excellent all-purpose fertilizer especially for lawns. It should be worked into the soil when planting turf and ornamental grasses.

Orchids must be fertilized on a regular basis! For best results, use Norman~s Optimal Orchid Nutrients every other week. It is recommended to pre-water plants before applying the diluted nutrient solution if the potting media is dry.

Definitely, fertilizer toxicity can have an adverse effect on your plants directly or may cause environmental damage. Major nutrients like nitrogen, potassium and sulfur in excess will cause marginal leaf burn. Excessive levels of phosphorus, calcium and iron will interfere with the availability of other nutrients. Minor nutrients like zinc, copper, and boron will cause leaf drop if over applied.

There is some dissention about whether it is recommended or not to fertilize an extensive greenroof – I believe the answer is yes, as most German roof greening professionals recommend. Use encapsulated slow release fertilizer twice during the first year of establishment in the early spring and fall, and then yearly thereafter for the next 4 years or so.

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.

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).

Because bonsai trees are cultivated in limited amounts of soil, adequate feed is very important. As a general rule, a small amount of feed is given in the spring and a larger amount in the fall. Feed for bonsai should contain three principle ingredients: nitrogen, phosphoric acid, and potash. It is also a good idea to use a fertilizer containing chelated iron. Water before fertilizing your tree and then apply at half the strength recommended by the brand's manufacturer.

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.

If you have a seedling, it can't handle full strength fertilizer. Many people use 1/2 strength and less often than a larger plant. Research this further before doing it. I fertilize my larger plants each time I water. I switch up between....Miracle Grow, Seaweed extract, or another high quality fertilizer. This species loves to be fed, but too much at one time isn't a good idea....you can burn the roots.

Spray your plant on all surfaces, top and bottom, as you would for normal watering. Do not soak your plant in fertilizer. Shake off any excess. See general care - fertilizing for more information.

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.
