Use Fabric Mulch
If summer weeds are a constant problem in shrub beds or around trees despite a 2-inch layer of organic mulch, consider weed barrier cloth. Now, while new weeds are small and easy to pull, clean out around the plants and install this fabric mulch under a new organic blanket.
Watch for Brown Patch on Lawn
The bane of St. Augustinegrass is brown patch fungus -- irregularly shaped brown areas that appear and grow in wet weather, then shrink in drier times. The fungus is also favored by excess nitrogen fertilizer, so don't feed the lawn in an effort to regrow the grass.
Keep Feeders Full
Whether they migrate through or stay the winter, birds are hungry now. Berries are gone, and the new feeder you filled in December is long emptied. Clean it now and refill with fresh seed. Store sacks of birdseed in plastic containers to keep them dry and safe to use.
Keep Fertilizing Annuals
Fertilize pansies, snapdragons, candytuft, violas, and other winter annuals with a soluble flower formula every other week. Especially when rainy weather patterns dominate, soluble fertilizer can too soon wash out of the root zone entirely and must be replaced. Even slow-release products like Osmocote can be diluted in rainy seasons.
Finish Planting Deciduous Plants, Potatoes, and Corn
The window is fast closing for several annual chores. Potato planting should wrap up by month, with corn planting well underway. Finish planting roses, shrubs, and trees by this month, especially if you are transplanting from one place to another or installing bare-root roses and other plants.
