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.
The test holes should be round and at least 6 inches, but no larger than 8 inches, in diameter. Dig each test hole as deep as you intend to excavate the soil treatment trench. The bottom of the percolation test hole must be at least 3 feet above the level of seasonally saturated soil or bedrock. A clam shell-type posthole digger can be used (Figure 2). If you use a 6-inch auger, it's a good idea to drill a pilot hole with the 3-inch auger.
