The time has come. If you live near Stockton GCC and have yet to put down your seasonal crabgrass pre-emergent, then try to get to it very soon. The recent wave of warmer days will raise the temperature in the soils around Stockton and crabgrass will be poppin' in no time.

I normally disregard the degree day model, going more on history and current weather patterns. I have applied pre-emergent as late as April 15th in some years, but this time around I'll be going a month earlier. Our long summers result in a long germination window for crabgrass so two applications may be necessary. Read the label of the product you are using and follow the instructions closely.

Crabgrass is very difficult to remove from your lawn, so prevention is the key.

Finally, be careful not to over-fertilize your lawn during the 'Spring Green Up' promotion at your local garden supplier. Two-thirds of the nitrogen applied to your lawn should be put out during the fall months. That is the time of year when the plant builds up its roots. Spring comes with a growth flush that is mostly top growth. The reserves are being used to push the plant up and most of the nitrogen will do the same.

Lowe's and Home Depot benefit from 'Spring Green Up' much more than your lawn. A little fertilizer this time of year will go a long way.
