Fertilizer Burn

on Rose Bushes

Simply put, this is caused by too much of a good thing- or adding to much fertilizer. It causes the leaves to turn yellow, brown, and wilt. 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 plants well after fertilizing. I like to fertilize when I know it's going to rain the next day (but I still water the fertilizer in).

Fertilizer burn will sometimes appear right away, but often it can take up to several weeks for symptoms to appear.

Solutions to the Burn

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. 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.
