What was this fertilizer?
Several years ago, my mother-in-law brought us several bags of rose fertilizer that were unlike anything I've seen before or since. It came in large clear bags, was brownish green and looked like little rabbit pellets about 1/2" long.
For each rose, you took about 1 cubic foot of the stuff and made a mound around the rose directly against the stem (these were tree roses). There was no mixing into the soil or watering required nor did it burn the roots. We did this at the start of the season and the mounds lasted at least three months. It worked great and seemed to do a really good job of enriching the soil as well.
Does anyone have any idea what this might be? I don't need a specific product name, I'm just wondering what it was and how I can find more of something like it.
(If you're wondering why I don't just ask her, it's because as soon as I did, she would insist on buying it for us and doing all the work herself. Helpful people can be so annoying :)
