• March: Apply Dormant Oil

    To eliminate any overwintering insects and diseases on fruit trees, apply dormant oil spray as directed on the package.

  • March: Prune Shrubs and Vines

    Hard to believe when the ground is thick with snow and the air is frigid, but spring is not far away at all. Now is the time to prune out any damaged, diseased or tangled / crossed branches and stems of summer-flowering shrubs and vines before they leave dormancy.

  • March: Winter Wounds on Young Trees

    The arrival of spring may show a vertical ‘split-like’ wound in the bark on the west or southwest side of a young or newly planted tree.  This wound, sometime called sun scald, is the result of the sun heating up the bark and stimulating cambial activity.  The cold temperature that follows kills the active tissue and a split occurs.  Clean the wound by cutting out the bark that is loosened and damaged.  Healing will begin on its own when the growing season starts.

  • March: Selecting Lettuce Seed

    Students at the Colorado State University studied varieties of lettuce seeds to determine which were most resistant to bolting.  Batavian lettuce varieties, a cross between leaf lettuce and head lettuce,  came out on top.  The most resistant Batavian cultivars were Nevada, Sierra and Tahoe.  Butter lettuce varieties also showed good resistance to bolting.   The study also showed that red romaine lettuces were good for individual leaf harvest and picking as baby leaves.

     

  • March: Starting Seeds Indoors

    A wide variety of containers can be used to start seeds indoors – the containers that your salad greens came in, yogurt containers, pots that you have saved from last summer, purchased pots and cell packs from the garden centre.  The important thing is that the container has drainage, sufficient depth for good root development and is very clean.  If re-using a container, wash it in a solution containing bleach.

  • March: Tuberous Begonias

    Start tuberous begonia tubers indoors about 6 weeks before the last frost date.  Place them in a shallow container filled with a growing medium that is porous but moisture retentive and does not contain fertilizer or manure.  Coarse sphagnum moss, peat moss or a good potting mix will all work.  Completely cover the tubers with the growing medium.  Keep the growing medium moist but not soggy.  Place the container in a warm spot with filtered sunlight.

  • March: Feeding Houseplants

    Now that the days are getting longer, it is time to start to feed your houseplants. Give them half the recommended dosage of plant food every other week rather than full strength every month.  Be sure that the growing medium is damp before you apply the plant food.

  • March: Late Winter/Early Spring Pruning

    Late winter/early spring is a good time to prune your deciduous plants for structure, or to remove damaged, diseased and dead branches. The structure of the plant is more visible during the dormant season, which allows you to make more effective cuts. Cut the branch just above an outward-facing bud, behind the point of injury, if any
