Do you know what Fertilizer burn on rose bushes is?
Do you know what to do to avoid plant burn? Defined as -Leaf scorch- resulting from over-fertilizing- refers to excess nitrogen salts.
Simply put, this is caused by too much of a good thing- or adding to much fertilizer. Symptoms of Fertilizer burn,is the leaves turning yellow, brown, and wilting. Excessive amounts of fertilizer can actually cause the plant to die, as not only the leaves but the roots, and the whole plant is affected.
The excessive build up of salts dehydrates the plant, causing plant burn.
Over-fertilizing interferes with the plants ability to absorb water, and even pulls water directly from the plant.
This can also happen if you fertilize the right amount, but don't give the plant enough water. It is Very important to water the soil around the plants well before applying fertilizer, and then again after fertilizing. The water keeps the fertilizer from burning the feeder roots, that are close to the surface. I like to fertilize when I know it's going to rain the next day (but I still water the fertilizer in).
Plant burn from over fertilizing will sometimes appear right away, but often it can take up to several weeks for symptoms to appear.
Remove any fertilizer still present. Water heavily to flush excess salts from the soil.
Always pay careful attention to the recomendations on the label of the product you are using. You don't want to take chances. More is NOT better when fertilizing!
Even fertilizer applied directly to the leaves (foliar feeding) can burn plants if not used as directed. Never use a foliar fertilizer when temperatures reach 8o degrees/F or 27 degrees/C. If you do use any foliar feeding, be sure to do it at a time of day, when the leaves will have time to dry off completely before night time. When rose leaves stay wet for any length of time, it gives disease spores a chance to take hold.
Consider using organic fertilizer when fertilizing roses, to help you avoid plant burn.
Organic fertilizers are the best fertilizer for roses, because they are derived from the remains of living organisms. These naturally occuring materials sustain the natural life of the soil. Because they have a low percentage of nitrogen, they release their nutrients slowly, and are unlikely to cause burning from the fertilizer. Examples of organic fertilizers include; Bone meal, cottonseed meal, blood meal, fish emulsion and cow manure.
