Willows can grow in well-drained soil if they are provided with additional water. In dry areas, clay soil is better for weeping willows than sandy soil because it does not drain quickly and retains more water. Weeping willows tolerate many types of soil, including alkaline, clay, sandy and clay soils. However, their preference is for moist, well-draining and slightly acidic soils.
If your soil is too alkaline, you can make it more acidic by modifying it with sulfur. Because weeping willows can reach 50 feet tall and wide, they need a wide strip of grass or patio to stretch out. They work well in areas that are naturally quite humid, but tend to lose a lot of leaves and twigs, so avoid planting them where falling branches can cause damage or injury. Weeping willows tend to grow in sandy soils with at least four hours of direct sunlight.
It thrives in areas with moisture, making it common to find it around ponds and lakes. These trees are also drought tolerant and can withstand high temperatures and humidity. Yes, my mother had a huge willow tree and her soil was very heavy clay. In fact, she had so much clay that she could have an unlined pond on her property.
The only time the pond dried up was during an extremely severe drought; and that was partly due to the fact that she drew water from the pond to water the rest of her garden. During the ice storm of '98, the tree was severely damaged when a huge sugar maple broke in half and fell on it. As a result, the maple and willow were removed, but the logs were allowed to remain. In 2004, a full-size willow tree had grown from the trunk.
So yes, a willow will not only grow on clay soil, but will also thrive on it. Probably native to China, the weeping willow is a dioecious tree that has male and female flowers. Oaks are one of the most common species of deciduous trees, not to mention that they top the list of the best-known trees. To minimize problems, provide adequate water to keep the tree healthy, as healthy trees are better able to defend themselves from disease.
When the tree enters the ground, you'll end up with some thinned foliage because those roots will no longer be able to support the top of the tree. Planting a weeping willow in your garden can bring a lot of enjoyment to your landscaping, but it's essential to research this tree before planting it. Good drainage around the crown of the roots of the tree is important, as well as access to moisture is necessary for the survival of the tree. You will want to cut all the branches, which will make the tree grow new branches, giving it an exquisite look.
If the leaves of the tree have yellow tips, apply 1 cup of tree and shrub fertilizer to the root area of the willow tree for every 1 inch of trunk diameter.
