Vigoro is a time released product with the following:
Total Nitrogen = 15% (7.31% Ammoniacal Nitrogen and 7.69% Urea
Nitrogen

One thing we in this hemisphere should be thinking about is the end of summer. Now is NOT the time to be putting time-release fertilizer on our plants, because the release is temperature-mediated. That stuff will sit there all winter long, creating a tim
ebomb for next spring, when it will solubilize too quickly, causing a salty soil and a release of ammonia (note those nitrogen sources above; urea breaks down to ammonia). Ammonia vapor is very toxic to plants, and in a cold frame or hoop house could caus
e severe phytotoxicity before you know it.

So if you need to fertilize, use some liquid form.


Brrrrrrr- I had frost last night!!!!!

Thanks again Nina.

Never thought of that heat release/time bomb issue.
Good reason for not using time released fertilizer.
Guess I'd better stick with Muracid.

Again ... I'm not terribly concerned about fertilizing the trees, just
providing them with nice acidic conditions rather than my hard well water.
