How to Keep Tree Roots from Killing Garden Plants

When planting a garden in the vicinity of a tree, it is important to take precautions to ensure that the tree roots do not harm the garden plants. Tree roots can compete with other plants for water and nutrients, and may even release chemicals that inhibit the growth of nearby plants. Here are some tips for keeping your garden plants safe from tree roots:

1. Plan Your Garden Wisely

Before planting a garden near a tree, it is important to consider the tree’s root system. Some trees have shallow roots that spread out wide, while others have deep roots that can penetrate deep into the soil. If you are planning to plant a garden near a tree with shallow roots, it is recommended that you choose plants with shallow roots as well. You may also consider using raised beds or containers to keep your plants out of harm’s way.

2. Create a Barrier with Landscape Fabric

Landscape fabric can be used to create a physical barrier that will prevent tree roots from encroaching on your garden. Simply lay down the fabric on the soil before planting your garden and cut holes in the fabric for your plants to grow through. The fabric will prevent the roots from growing through the soil and competing with your garden plants.

3. Use Mulch to Smother Tree Roots

Mulch can be used to smother tree roots and prevent them from growing towards your garden. Simply cover the soil around your garden with a layer of mulch, making sure to keep it away from the stems of your plants. As the mulch breaks down, it will release nutrients into the soil, benefiting your garden plants while also preventing tree roots from growing through the soil.

4. Water and Fertilize Regularly

By regularly watering and fertilizing your garden plants, you can help them develop strong roots that can compete with tree roots. Water your plants deeply and infrequently, rather than giving them frequent shallow waterings. This will encourage them to grow deep roots that can reach water deep in the soil. Additionally, fertilize your plants regularly with a balanced fertilizer to help them grow strong and healthy.

5. Prune Tree Roots

If you are experiencing problems with tree roots invading your garden, you may consider pruning them back. However, this should only be done by a professional arborist, as pruning tree roots can be dangerous and may harm the tree if not done properly.

With these tips, you can ensure that your garden plants remain safe and healthy despite the presence of nearby trees. By planning your garden wisely, creating a barrier with landscape fabric, using mulch to smother tree roots, watering and fertilizing regularly, and pruning tree roots if necessary, you can enjoy a beautiful and fruitful garden without worrying about the harmful effects of tree roots.
