You can cut the taproot of a plant, and it won't harm it. When the taproot of a plant is cut, it will start to regrow secondary roots. The secondary roots will be capable of supporting the plant but won't be as strong as the original taproot.
If you are transplanting a plant with a root-bound taproot, there is an opportunity to fix it. When the plant's roots are exposed, you can cut away the twisted part of the taproot. Cutting off the twisted part of the taproot will give the plant a chance to grow new roots downward.
There are a few ways to encourage deep taproots to help your plants be more drought resistant and stable. Let's look at the best ways to encourage deep taproots and learn how they function.
Deep watering is when you allow water to work its way deep into the ground. When the water is deep in the ground, the roots will grow towards it.
Appling fertilizer to your plant will encourage deeper taproots. It's vital that whatever fertilizer you use contains all three of the essential nutrients for plant growth.
Root pruning is another way to encourage a plant to grow deeper taproots. Start by exposing the upper root mass of your plant. Not entirely removing the plant from the ground is vital, as doing so can damage the taproot.
