Best Trees for Rain Gardens
In addition to enhancing the looks of most houses, appealing landscaping elements like rain gardens also have significant environmental advantages.When constructed appropriately, rain gardens can hold and collect a sizable amount of rainwater, which will then soak into the soil over the following several days. This aids in avoiding some of the issues that large volumes of runoff water frequently bring about. Additionally, the water gathered can be utilised to sustain trees and plants, especially some that ordinarily need more water than the region regularly provides.
Although there are many various methods to build a rain garden, the majority of them involve excavating a small to medium-sized depression and then installing a channel that feeds the garden with rainfall gathered from a downspout or gutter. The depression is subsequently filled with plants, and different gravels and soil additives are added to promote effective percolation. Remember that rain gardens are not ponds; a few days after the rain stops, there shouldn't be any standing water left in the depression.If you want to offer the trees the best chance of prospering, you must choose species that can adapt to the circumstances present in or close to the rain garden.The many microhabitats found in rain gardens often support a variety of tree species. While the raised portions around the perimeter of the rain garden will include drier soil, which is better suited for trees with modest water requirements, the soil in the lowest part of the depression will remain reasonably wet, making it suitable for trees with high water requirements.
Trees of all kinds can be utilised in rain gardens, including:
Rain gardens naturally suit the bald cypress. Bald cypresses grow well when given enough water, and they'll do well in the lowest parts of your rain garden. The main difficulty posed by bald cypresses is their size when fully grown; they are substantial trees that can grow to heights of 60 to 80 feet.
Goodding's willow is among the greatest willow species to employ, although many different willow species make excellent selections for rain gardens. A number of bird species can also find food and refuge in the Goodding's willow. Goodding's willow may grow to a height of around 25 to 30 feet, thus small rain gardens shouldn't use it. The majority of the rain garden, including the depths of the depression, will support Goodding's willow.
Another tree that thrives in woodlands is the red maple. Red maples may be planted in almost any area of your rain garden since they do well in soils with different moisture contents. The rather dry soils in the upper levels will not be a problem for them to adapt to. Red maples offer stunning colour in the spring and, to a lesser extent, the fall. Because of their potentially invasive roots, it is best to keep them away from hardscapes like sidewalks.
4. Chinese Fringe Tree
A kind of moisture-loving tree that does well in the centre of your rain garden is the Chinese fringe tree. The Chinese fringe tree is a small to medium-sized tree that normally grows to heights of 10 to 20 feet and is well-known for its spectacular, white blossoms. Note that this tree may not be a suitable choice for rain gardens that are situated close to bedroom windows, rear porches, or front doors since it may create allergy issues for certain individuals.
