You can improve clay soil’s structure by adding a mix of 80% gypsum and 20% dolomitic lime. Use an ounce of this mix per square foot of soil in spring and again in fall. This may be repeated for a second year, while also adding as much organic matter as possible. Adding calcium m...
Wheat is grown in many areas of the world with environmental conditions similar to those in southeastern Kansas. Rainfall averages 100 cm year 1 and the subsoil has a high clay content, which probably impedes percolation and drainage. Much of the rainfall occurs over winter when the wheat is...
Plant in well-drained soil! If soil is heavy, add roughage such as pine bark mulch (Make sure it's ground BARK not ground WOOD). Do not overwater, especially in clay soil. This can lead to root rot. Do not plant too deeply. Plant at the same depth as the height of the root bal...
The amount should be about 1/3 to 1/2 of the volume of the soil removed from the hole. See Improving Clay Soil for ways to fix drainage issues in clay soil. For Sandy Soils: Use straight garden compost, composted manure, or a combination of the two. Again, the amount should be ...

New roots establish more quickly in a hole that is roughly twice the diameter of the root balland no deeper than necessary to let the tree stand at the same level as the surrounding soil—or higher, if the tree is to be planted atop a mound for proper drainage. The base of the tree...
The plastic or HDPE drainage board are made from HDPE(high-density polyethylene), using high pressure to inject plastic to form hole-lump-shaped shell, with stereo space and support level; in the top of the shell, covering with non-woven as filtering level for water percolatio...
Layer a bed of clay pebbles along the bottom to increase drainage. Cover with a little potting soil mixed in with garden soil together. Remove the tulip tree from its pot and break the clump up to free the roots. Settle the root ball in the hole and position a stake as close to the...
The trick for growing carrots in clay soil is to improve soil porosity and drainage, and break up all the heavy clods. See Improving Clay Soil for more information.Since this is so much work, you’ll have much better success with Nantes, Chantaney, or “Mini” varieties when growing ...
