Improving Heavy Soils
What is adobe? What kind of plants will grow best in adobe? In this
Redwood City I find clay-like soil which looks very dark and heavy. What
kind of plants will grow best in this soil?
The term adobe does not mean any particular kind of soil. It is applied
locally to clay and clay-loam soils indiscriminately. It generally
signifies the heaviest, stickiest, crackingest soil in the vicinity.
Most plants will grow well on heavy soils if they are kept from getting
too dry and too full of water. This is done by using plenty of stable
manure and other coarse stuff to make the soil more friable, which
favors aeration, drainage, root extension and plant thrift. Friability
is also promoted by the use of lime and by good tillage. The particular
soil to which you refer is a black clay loam which can be improved in
all the ways stated. It is a good soil for most flowers and vegetables
if handled as suggested. You can get hints of what does best by studying
your neighbors' earlier plantings.
