What are the signs of poor drainage in a garden?
Poor drainage in a garden can be identified by several signs. One of the most obvious indicators is the presence of standing water after heavy rain. If puddles linger for hours or even days in your garden, it’s a clear sign that water is not draining properly. Additionally, you may notice waterlogged soil, which can lead to root rot in plants, balding patches of grass, or a muddy mess that prevents you from using certain areas of your garden.
Another sign to watch for is the growth of water-loving plants or algae in areas where water tends to accumulate. Weeds tend to thrive in poorly drained areas, and excessive moisture can lead to plant diseases, making your garden less healthy overall. Observing these signs can help you determine if your garden needs drainage improvement.
How can I improve drainage in my garden?
There are several effective methods to improve drainage in your garden, starting with the modification of soil composition.
