Dealing With Clay Soil
Saturday, December 6th, 2008When moving to a new home, or when deciding to tackle your yard or backyard for the first time, it is important to note certain aspects of the garden, such as which areas get most daylight. This is one of the reasons why professional gardeners advise studying a garden for 12 months before designing anything new. One area where you can get to work immediately is improving your ground and this is especially important when dealing with problematic situations such as when you have clay soil.
Clay soil can make a gardeners life a misery as the ground is heavy and easily becomes waterlogged. Sadly there are no real quick solutions to the problem of too much clay but, on a brighter note, by hard work you will end up with seriously fertile, good quality, loam by following a few simple steps.
If you have moved into a newly built house it is important to remember that the soil in the area will be somewhat compacted and it will need double digging immediately. Make sure you do not disturb the subsoil but dig as deep as you can removing any rubble, bricks and other debris. As you work your way across your plot dig in as much organic matter as possible.
Adding organic matter will improve the drainage and add air but it also helps create the correct environment for most garden plants and clay soil is, potentially, highly fertile. While many trees and shrubs will grow well in a heavy soil they too will benefit by the addition of humus and compost. When it comes to annuals and herbaceous plants clay can cause problems (plus you will need to dig up and divide some perennials).
When you dig clay soil for the first time I strongly advise that you add a great deal of compost and other organic matter, about eight inches across the whole surface would be perfect. However you should not over dig the soil as this can compound the problem, especially if the ground is wet.
After your first double dig and in following years you should continue to add organic matter to the ground but there will be no need for any double digging. You can place the organic matter across the surface of the soil and, by the work of worms and weather, it will eventually mix in nicely.
In certain areas of the United States there are unique aspects of clay which necessitate the addition of certain chemicals or maybe a some other substances. I may address some of these problems in a later article.
