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.

Citrus is to be fertilized three times per year: February or March, May or June, and October or November at the rate of one pound per year of the tree's age with a maximum of thirty pounds per year application. A 6-6-6 or 4-6-8 citrus special with minor elements or trace elements would be the recommended analysis. Apply the fertilizer to the entire rooting area, which extends from the trunk out to several feet beyond the drip line of the tree. See similar questions...

The trees should be fertilized at least three times a year in October, February and June. For any type of citrus, measure the circumference at the base of the trunk and calculate one pound of citrus fertilizer for every inch measured. Then divide this amount into three applications. Keep the area underneath the tree clear of all grass, weeks and mulch. See similar questions...

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. See similar questions...

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. See similar questions...

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. See similar questions...

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. See similar questions...

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. See similar questions...

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. See similar questions...

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.

Start with what you like. If you like oranges pick a naval, blood, or Valencia. If you like grapefruit pick the white Marsh or a pink Ruby. What you really need to consider is where your citrus is going to be grown. Some are more susceptible to frost damage than others. And although there is always talk about covering citrus trees to get them through the cold nights of winter it's a lot of work. See similar questions...
