With all the rain we’ve had lately, you may be wondering how this excess water affects our plants! For areas that drain well, our rainy periods shouldn’t have a negative effect. However, heavy clay soils that are not amended with organic material (like compost) can prevent easy drainage. Why is water a problem? Excess water in the soil forces out air. When there is less air available, the oxygen is rapidly used and becomes inadequate for good root growth. Adding compost is a great way to loosen clay soil and improve drainage. Adding a trench to divert water away from plants works well too.
