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). See similar questions...

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...

Yes, bonsai receive regular applications of fertilizer throughout the growing season. Because the grower is not attempting to "boost" the plant's growth rate, fertilizer is given at a rate that will insure healthful growth, but not encourage excessive growth. Common water-soluble fertilizers, such as one might use on houseplants, are fine. Slow release organic fertilizers will also work well. Use at the label rate. 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...
