In any gardening guide, you’ll often see the terms like “good drainage” or “well-drained soil” or “plants in poor soil drainage”. A good soil drainage is a vital requirement for almost any plant to flourish well. But what do the terms “well drained” and “good drainage” actually mean? Are there plants that do well with poor soil drainage?
A well-drained soil is the type of soil where excess water caused by unchecked watering or heavy rain dissolves quickly. Contrarily, if you see a large splash of water on the ground after a hard rain shower, your soil is not draining efficiently. This may cause plant roots to sit deep in water for long periods and prevent them from carrying on adequate respiration to their stalks and leaves. This could slow their growth or even kill them by rotting.
When growing plants in pots, the prime cause of poor drainage are the use of containers having no drainage hole. At least, one hole should be in the pot’s base to allow unnecessary water to drain away.
