English Name

Water Mold Root Rot

Description

Most fungi love wet conditions, and overwatering can produce such conditions. When the soil your bush is planted in is overwatered and it has poor drainage and water stands too long at the base and around the roots, then your bush is at risk of developing water mold root rot, a condition that is caused by a variety of fungi.

Infects

Shrubs

Tips

For heavily infected soils, try solarization.

Symptoms

The fungi start a rot that invades the roots and then it works its way up the plant. After that the rot is established you will see dark discolorations in the plant's roots and stems. The leaves look dull and some are even yellowing and wilting.

Control

There is no cure for this disease, so once the bush is infected there is little you can do but remove it. Before you plant another bush in its place, make sure the area drains properly. Good drainage will prevent the wet conditions the fungi love.

The world's tallest-growing tree is the coast redwood (Sequoia sempervirens), which grows along the Pacific Coast of the United States, mainly in California. Interestingly enough, it's not the world's oldest-growing tree; that award goes to a bristlecone pine (Pinus aristata).
