Ideally, rising timber must be fertilized all year long however a bit otherwise as timber age. A tree wants bigger quantities of nitrogen (N) based mostly fertilizer through the rising season. Nitrogen-based options must be utilized through the early spring and summer season months.
A number of gentle functions a 12 months are most well-liked because the tree will get older to a degree the place they want little or no fertilizer. A soil check could also be wanted to find out the quantities of phosphorus (P), potassium (Okay). Learn the label for correct ratios and software charges of N, P, and Okay for timber.
Vital Age Issues
Right here is how it’s best to fertilize a tree because it ages:
- Newly planted tree part – these timber are nonetheless infants and will have solely minimal functions of a fast launch fertilizer and extra of a sort that releases slowly. Excessive nitrogen launch charges on newly planted timber will burn roots and leaves on contact. Word: Liquid and absolutely composted fertilizers have the quickest launch charges whereas gradual launch varieties are typically granular and fewer water soluble.

Natural fertilizers are tougher to seek out than inorganic fertilizers and infrequently dearer however they’re the least dangerous and fewer exacting when making use of. The most effective natural fertilizers are cottonseed meal, bone meal, manure and hen litter. Learn the label (if packaged) for software strategies and quantities to make use of.
Inorganic fertilizers are cheap and are probably the most steadily used fertilizers for timber. Inorganic nitrogen based mostly tree meals sources are sodium nitrate, ammonium nitrate, and ammonium sulfate.
Normal objective fertilizers are full with N-P-Okay which is often outlined because the ratio of nitrogen, phosphorus, and potassium within the combination. You should utilize these glorious fertilizers however do not overdo. Use high-ratio nitrogen merchandise except a soil check suggests an absence of different vitamins. Inorganic fertilizers can are available slow-release, liquid or water-soluble for foliar software.
Learn the label for software charges.

The best worth of most natural supplies is within the change they convey to soil construction. Do not forget that chemical fertilizers don’t have any constructive bodily impact on soil construction.
Peat moss, leaf mould, aged pine bark, or sawdust and steady manure can enhance the soil whereas including vitamins. These amendments enhance the fertilizer and water-holding capability of many soils. Mulching with these amendments aids in root improvement.
