When thuja trees start turning brown, it’s time to take action. Home remedies are all you need

A beautiful thuja hedge is a highlight of many gardens. While some of us often prefer deciduous trees, this traditional option remains very popular. It’s no wonder, as thuja trees offer many advantages. For one thing, they stay relatively green all year round, and for another, they create a screen that looks nice and ensures plenty of privacy. Often, however, they start to turn brown, which is very unpleasant. At this point, we need to tackle the browning. How? Using home remedies. It’s easy to handle.

Why do arborvitae turn brown, and what does the brown color indicate?

In some cases, arborvitae begin to dry out and turn brown. It’s not exactly pleasing to the eye, but the main concern is the health of the tree itself. The brown color often indicates a serious infection that we certainly shouldn’t underestimate. But thuja trees turn brown for other reasons as well. The brown color can also easily be related to insufficient hydration. Simply put, thuja trees also need to be watered occasionally during dry periods. Thuja trees are also bothered by excessive fertilization. That is also undesirable. Pests may also be to blame. Aphids, for example.

How to make a protective spray for thuja trees using garlic?

Garlic is an excellent insecticide and is undoubtedly suitable for thuja trees in the form of a spray. Simply peel two heads of garlic, crush the cloves, and pour a liter of water over them. This homemade mixture is then left to stand and steep for about a day. After that, strain it, pour it into a spray bottle, and apply it to the arborvitae. We should use this mixture until the arborvitae turns green again.
