Finally, March is here.  Our amount of daylight is increasing.  Daylight Saving Time kicks in March 8.  Spring is here March 20.  All sounds good to me, especially after the snowfall we just experienced.  Now, is Mother Nature on our side to delivery us a mild March?  Do you remember last March?  We had a cold, wet, and wintry March = not great for spring gardening.  Let’s all hope for a great gardening month this year.  Regardless of what happens we still have garden chores to do in March.  Here are a few March gardening tips:
  1. Remember to apply the pre-emergent crabgrass preventer when theforsythia shrubs are in bloom.
  2. Now is a good time to pinch back your winter hardy pansies and feed them.  As we warm in March pansies will put on a spectacular show of color.
  3. After pussy willow catkins have passed their prime, prune the plant drastically to encourage long branches and large catkins for next year.
  4. Cut back your liriope, monkey grass, and your ornamental grasses now before new growth emerges.
  5. March is a great month in which to plant cool season veggies such as broccoli, lettuce, spinach, cauliflower, collards, carrots, peas, and others.
  6. March is a good time to apply a fresh inch or two of mulch.  Do not build the mulch up too high at the base of your plants.
  7. Now is the time to trim your boxwoods.  The proper method of trimming is to thin out branches that will allow sunlight to reach the center of the boxwood.  DO NOT SHEAR JUST THE OUTSIDE!  This is bad practice.
  8. Take some of your boxwood trimmings.  Strip the bottom half of the cutting of leaves and stick the stem into some rooting hormone powder.  Then take the cuttings and place in a rooting medium.  Keep the soil moist and protected from the wind and direct sunlight.  You will soon have roots growing on the cutting.  And, you have just created some new boxwood plants.
  9. March is the month to prune your evergreen hedges such as bayberry, ligustrum, laurels etc. to get them in shape for the upcoming growing season.
  10. Now is the time to prune fruit trees just before they bloom.   And, before they leaf out you should spray your fruit trees with a dormant oil spray or with lime sulfur to kill any insects living on the tree trunk or branches.

Thanks for the tips. I really appreciate your informing customers about when to put down the crabgrass treatment. With the winter being so cold I was not sure when to put it down.
