How quickly is miracle grow absorbed. Due to neglect, my containered cherry tomatoes were greatly in need of water and fertilizer. I gave them the proper dosage, and 12 hours later we had a heavy rain come through.
A stump grinder uses a spinning blade fitted with carbide tipped teeth that scrape away at the stump. Bear in mind that a stump grinder can only work to a limited depth, normally up to 10-12 inches. If you feel up to it, stump grinders can be hired by the day at most local hire shops. If you decide to use a contractor to do the work for you, expect to pay a minimum of around Â£65 plus VAT for the smallest of stumps.
BTW....when I first got my stump grinder, the first job I did was for free, so I could get a little experience with the machine, and get an idea of what I needed to charge to make money with it. And if I tried to charge $3-4/ square inch, I'd never have to grind a single stump.
