Why shrubs turn brown

Instead, leave the branches with brown needles in place so that the green needles will come back next year. The green needles will grow on top of the brown needles, which is why the branches do not need to be cut. Green needles will begin to grow on their own as early as the following year; however, there are things you can do along the way to help the process.

Once the green needles have begun coming through the next year, you will want to cut away any of the brown branch tips that still remain. Cutting off these brown branch tips will allow new buds to grow quicker and fuller the following year. A sturdy bypass pruner would be a suitable tool for this exercise. Prevention is one of the best practices you can put into place to keep your evergreen from turning brown. Even though healthy evergreens can turn brown naturally due to lack of water or a cold, dry winter, you can prevent this from happening with just a little bit of work.

Each fall, you will want to water the evergreen more than normal. The evergreen will store the extra water to use throughout the winter. This will keep the evergreen from turning brown in the winter months when the ground is frozen, and water is scarce.

New growth can come in as brown if the tree has used the water supply from the winter to hydrate the already present growth on the evergreen. This is known as spring dryness. If you see that new growth is coming in brown, you should immediately start to water the evergreen. We recommend watering the evergreen with about 1 inch of water each week. Do this until the brown needles begin to turn green. Preventing your evergreen from turning brown is not the same as maintaining or recovering your evergreen.

Actively taking steps each year to keep your evergreen green is prevention. Prevention should be done each year to ensure that the evergreen does not turn brown, to begin with. Prevention means that you will sufficiently water the evergreen each fall before the winter begins. As soon the weather turns cold and the ground freezes, the evergreen will not be able to absorb water as it does during the warmer months.

Prevention is ineffective at this point as the ground will be too cold for the evergreen to absorb any sufficient amount of water to keep the needles from turning brown. Nothing feels better after a hard day at work than sitting in a comfortable place with the family, admiring the beauty of nature all around you. But what if something is wrong? Bushes play an important role in creating a beautiful home.

Whether evergreen or deciduous, bushes play a vital part in any landscaping plan. However, bushes can take years to reach their full potential.

Often additional watering or erecting some type of shade can help younger plants cope with temperature swings.

The affected bush or bushes will usually return to a healthier look as soon as the temperatures become more normal for the region.

Often the weather extremes will make the bush more susceptible to damage from insects or disease. An insect infestation can cause plant leaves to turn brown or appear damaged. While geographic location and time of year has much to do with the pest causing the damage, a good starting point is to look for bag worms, spider mites, aphids, wood borers and leaf mites.

Rabbits, squirrels, deers and other animals can also cause damage leading to brown leaves.
