What to Plant Under Lilac Tree: A Comprehensive Guide

Lilac trees are beautiful and fragrant additions to any garden, but there's one challenge that comes with planting them: finding the right plants to grow underneath them. The shade and shallow roots of lilac trees can make it difficult for other plants to thrive. However, with careful selection and planting, you can create a stunning flowerbed that's both colorful and complementary to your lilac tree. Here's a guide on what to plant under lilac tree.

Consider the Light Conditions

The first thing to keep in mind when selecting plants to grow under a lilac tree is the amount of light they need. Lilac trees grow tall and wide, and as they mature, they provide a significant amount of shade. This means that the area underneath the tree won't receive as much sunlight as other parts of your garden. You'll want to select plants that are shade tolerant, but also don't require full shade. Opt for plants that need partial shade or dappled sunlight, and choose a spot under the tree where they will receive the right amount of light.

Choose the Right Plants

The next thing to consider when selecting plants to grow under a lilac tree is their root systems. Lilacs have shallow roots that extend out from the tree trunk, and this can make it difficult for other plants to grow near them. However, there are several types of plants that are well-suited for growing under lilacs. These include groundcovers such as hostas, ferns, and lily of the valley, as well as shade-loving perennials like astilbes, bleeding hearts and columbines. You can also consider adding some colorful annuals like impatiens, begonias or caladiums for added color.

Consider Companion Planting

Another way to make the most of the space underneath your lilac tree is to use companion planting. Companion planting is the practice of growing two or more plants together, where one plant helps to benefit the other. In the case of a lilac tree, you might consider planting some herbs or vegetables under the tree, such as basil, lettuce, or spinach. These plants can benefit from the lower temperatures and extra moisture under the tree, and in turn, their root systems can help to improve the soil and prevent erosion. Just be sure to select plants that are compatible with each other and have similar growing requirements.

Provide Adequate Water and Nutrients

Finally, it's important to make sure that the plants growing under your lilac tree are getting enough water and nutrients. Lilacs need a lot of water, and their shallow root systems can make it difficult for other plants to get enough water. Be sure to water regularly, especially during dry spells, and consider adding a layer of mulch around the base of your plants to help retain moisture. It's also a good idea to fertilize your plants regularly, using a balanced fertilizer that's appropriate for the types of plants you're growing.

Closing Thoughts

With the right selection of plants and careful planting, you can create a beautiful and thriving flowerbed under your lilac tree. By choosing shade tolerant plants, using companion planting, and providing adequate water and nutrients, you can make the most of the space under your tree and create a stunning garden display. So roll up your sleeves, put on your gardening gloves, and get ready to dig into this exciting project!
