Bermuda grass blades turning yellow.

Some types of grass appear yellow during seasonal temperature changes when they enter a dormant or resting phase. When excess water moves nutrients out of the soil the grass may turn yellow or light green and need more than the usual 1 pound of nitrogen per 1 000 square feet each year. Or wait until spring when the grass will return to its growth season green. For example bermuda grass is a warm season grass that goes dormant in winter.

Have mowed last week for the second time about 3 inch down to 1 inch. If dormancy makes your grass yellow you can try over seeding with another grass type. Iron another reason for discoloration could be lack of iron in your soil. Improper mowing exacerbates the buildup of thatch on lawns especially on bermuda grass fescue and bluegrass lawns.

In fall and winter bermuda grass can turn especially yellow because bermuda is a warm season grass. Your grass will have shallow roots and will suffer from poor uptake of nutrients oxygen and even water itself causing the lawn to start turning yellow. Too much water leads to a limited supply of oxygen in the soil due to waterlogging. The thatch turns beige in color and shades the grass plant s sheath and lower leaf blade.

Overwatering causes your grass to have poor root development. Grass cycling leaving grass clippings on your lawn after mowing adds nitrogen naturally to the lawn. Before mowing it s all green after mowing some patches turns yellow. Exposing thatch makes a low look beige to yellow again the result of mowing too short or at too long of intervals as the grass grows.

Check for irregular light yellow patches in the lawn as well as small yellow flecks on individual grass blades. These flecks enlarge as the disease progresses causing a rupture of the blade s surface and the release of yellow orange powdery spores that stick to everything from shoes and pant legs to mowers and pets. Some of the more common areas of the yard that you might find turning yellow from iron deficiency are those adjacent to things made of concrete. Avoid cutting more than 1 3 of the grass blade after your first cut of the year.
