Bloom Food?

onederwMarch 14, 2013

Okay, I'm officially Confused. (Nothing new there.)

From what many here have posted, I was under the perhaps mistaken impression that a dose of high nitrogen fertilizer would would serve as a "kick in the pants" for roses to explode into glorious bloom. When I look at what is marketed as "Bloom Food," however, I'm noticing that many of them are not high N, but rather high P--P as in phosphate.

In the back of my mind I'm hearing Karl Bapst remind me (yet again-I'm a slow learner about this) that "roses can't read," but still, which is it that jumpstarts bloom--Nitrogen or Phosphate?

Phosphorous.

Too much nitrogen will tell the plant to grow stems and leaves at the expense of flowers.

Ground rock phosphate is a good choice. But roses also like all the nutrients, including the micro.

Fish emulsion is the kick in the pants for me. Every year some one wants to take pictures of my roses and I am known as the rose lady on the hill(per the neighbors ref.) But then I live in a desert area, so any flowers are treat.
