If
you want to prevent crabgrass this summer, now is the time. I know it
sounds strange but we have to prevent the seeds from germinating before
the soil reaches 50-55 degrees. Apply a pre-emergent herbicide that
contains Dithiopyr, (brand name Dimension) now and you will be blessed
with protection from this grassy weed for several months. Now is also a great time to fertilize your lawn. You can usually find fertilizer mixed with crabgrass prevention in the local home stores right now. Just remember, these products effectively stop seeds from germinating.
If you were planning to over seed any bare spots in your
lawn, do not use. The cool weather in January is also the best time to
hard prune your rose bushes. They can safely be dramatically trimmed
back now. Prune away any crossing branches, dead wood, and shape them.
Plant bare root trees and roses in the garden, and if you are feeling
really ambitious, plant winter blooming annual flowers now too. You will
be rewarded with the showiest yard on the block.
