Hydrangea shrubs have a densely woven, fibrous root system that soaks up the moisture in the soil. The roots of the hydrangea shrub are fragile compared to trees and other larger plants, so they will often lose when put into root competition with a tree in the area.
Are hydrangea roots destructive?
Hydrangeas are considered caning shrubs or those that develop new growth/stems – the canes – directly from the root crown and that can over time significantly increase the size of the shrub. So while they can sometimes spread, they are not invasive.
How aggressive are hydrangea roots?
Hydrangeas planted under a tree often fail to thrive. This is because trees roots are very aggressive and are drawn to the rich, moist soil usually provided for hydrangeas.
Do hydrangea roots spread?
Typically, your hydrangeas need between 3 and 10 feet of space between each plant, depending on the variety. The roots commonly spread to the plant’s drip line and slightly beyond. This wide spacing provides ample access to critical moisture and nutrients that may not be in the hydrangea’s immediate vicinity.
Do hydrangea roots grow deep or wide?
Hydrangea roots don’t usually extend deeper than six inches, but you want to be thorough, so dig down about eight inches just to be safe. Once you’ve made your cuts in a complete circle around the plant, start digging in toward the center and loosening up the soil.
How do I stop my hydrangea from spreading?
Edge the area you want to keep intact. Use a sharp spade to cut through the rhizomes (underground root-like stems) to disconnect the hydrangeas you want to keep from those you want to remove. Continually prune the unwanted stems to ground level whenever they appear. Over time these stems should weaken and die.
Do hydrangeas have deep or shallow roots?
Because hydrangeas have shallow root systems, mulch well to prevent them from drying out.

How do I get rid of hydrangea roots?
Using a spading shovel, dig a shovel-deep ring just outside of the leaf line of the plant at a 45-degree angle. Make only a single cut, disturbing the roots as little as possible. Keep the plant watered thoroughly the next few days so the roots have time to recover.
