  • MARCH Week 1

    Fertilize pansies

    Fertilize pansies. Since the soil is warming, use any water soluble houseplant fertilizer, one half pint to one pint of solution per plant.

    See Success With Pansies

    Trim liriope

    Cut most of the green foliage off of tattered liriope. A mower, set to its highest setting, is the best tool for large areas.

    Add lime to your lawn

    If you haven’t spread lime on your lawn in a year, it’s time once again. Use 40 pounds per 1000 square feet.

    See How to Soil Test

    Seed tomatoes and annuals

    Prune boxwood

    Prune boxwood – but not with shears. Use a hand pruner to make foliage “holes” in the greenery so light can penetrate to the trunk.

    Spray your fruit trees

    Spray a fungicide (Captan, etc.) on apple and peach trees while the blooms are on the tree.

    see Fruit Spray Guide

    Prune your hollies

    Now is the time to prune giant holly shrubs back to a manageable size. Don’t be shy – you can cut them to eighteen inches tall and they will come back.

    Check for insects

    Camellia cleaup

    Remove spent camellia blooms from the bush and from the ground. You’ll prevent camellia petal blight.

    Prune roses

    Last chance to prune bush roses to approximately one half their present size.

    see Rose General Care

    Repot houseplants

    Repot houseplants you plan to move outdoors. Their roots will need more room as they grow rapidly in the sun.

    Hold off on the caladiums

    Wait to plant gladiolus, canna and caladium bulbs until mid-April – they all need warm soil in which to grow.

  • MARCH Week 5

    Plan before you build

    Building near a tree? Be careful – ninety percent of the tree’s roots are in the top twelve inches of soil.

    Pruning

    Forsythia, quince and winter honeysuckle can be pruned to a smaller size after flowering.

    Fertilize shrubs

    Fertilize shrubs: 1 tablespoon of 10-10-10 (or shrub fertilizer) per foot of height.

    Mower maintenance

    Sharpen your mower blade or replace it with a new one.
