1. Understand the tree’s root system.
Before you start planting, it’s essential to understand the root system of the tree you want to plant under. Trees have large, deep roots that suck up water and nutrients from the soil, which means planting too close to the trunk can disrupt the tree’s health. You should also avoid planting anything too shallow, as the roots can quickly absorb any nutrients and water meant for your plants.
2. Choose the right plants.
Choosing the right plants for planting under a tree is key to creating a successful garden. You want to select plants that can handle shade, as most trees will block a significant amount of sunlight from reaching the undergrowth. Ferns, Hostas, and groundcovers such as Creeping Thyme and Ivy are great options. Additionally, consider choosing plants that won’t require a lot of water. Since the soil under trees is typically drier than other areas of the garden, plants that don’t require a lot of water will be more successful.
3. Prepare the soil.
Once you’ve chosen the right plants, you need to prepare the soil for planting. Begin by removing any grass or weeds from the area you want to plant. You can do this by using a spade or a hoe, or by spraying the area with an herbicide. Be sure to follow the instructions on the herbicide, as some products can be harmful to tree roots.
Next, loosen the soil with a garden fork or cultivator. This will help to improve drainage and create space for your plants’ roots to grow. If the soil is particularly dry, you can add some organic matter such as compost, peat moss, or aged manure to help retain moisture.
4. Planting.
When you’re ready to start planting, be sure to space your plants accordingly. You’ll want to put the smallest plants closest to the tree, with the larger plants towards the surrounding areas. Make sure you dig a wide hole and avoid damaging any tree roots, as this can harm the tree’s overall health.
5. Mulching.
Mulch is essential for planting under a tree. It helps to retain moisture, prevent weeds, and insulate the soil. However, you need to be careful when mulching around trees. Ideally, you should create a mulch-free area around the trunk of the tree. Too much mulch around the trunk, referred to as “mulch volcanoes,” can cause the bark to rot, which can damage the tree.
6. Maintenance.
Finally, maintain your garden regularly by weeding and watering as needed. If your plants are struggling, consider using a slow-release fertilizer specifically designed for trees. However, be careful not to over-fertilize, as this can also harm your plants and the tree.
In conclusion, planting under a tree can be a challenge, but with careful planning and preparation, it’s entirely possible. By understanding your tree’s root system, selecting the right plants, preparing the soil, and maintaining your garden regularly, you can create a beautiful and thriving garden space that you and your tree can enjoy for years to come.
