  • March garden tips & tasks

    If your fescue lawn looks a little skimpy, overseed early this month. Fescue grows best when the weather is still cool.

    Clip dead stems from perennial herbs – thyme, sage, lavender, rosemary. Pruning encourages vigorous new growth.

    Prune nandinas, flowering quince and other airy shrubs by reaching in and removing about a third of the branches at ground level.

    Remove mulch or leaves that may be covering perennials in garden beds.

    Prepare a new garden bed: Have the soil tested (check with your county’s Extension service). Remove grass and dig or till soil 8 to 10 inches deep and mix with soil amendments and organic matter to improve drainage.

    Add fertilizer lightly to perennials as soon as you see new growth. Too much fertilizer may result in lanky growth.

    Herb transplants that don’t mind cool weather -- parsley, cilantro, sage, oregano – can go in the ground now.

    When you cut daffodils to bring inside, cut the stems at an angle and place them in water right away. Change the water in the vase daily to keep them fresh longer.

Replace landscape plants in fall and winter

We have lost many of the shrubs around our home. How late can we replant all of the landscaping around our residence? Is November too late?

ball burlap treesIf you are planting shrubs and trees, November is actually a good time to replant. Trees and shrubs planted when they are dormant have an easier time establishing good root systems before they begin actively growing again next spring. They will need to be watered at planting time and throughout the season, but not as often as you would have to provide water in spring or summer.

Here are general guidelines from UT/TSU Extension for planting balled-and-burlapped and container-grown trees and shrubs:

-Choose your location and begin by digging a wide hole, two or three times the width, but no deeper than the height of the root ball.

-Handle the trees carefully before you plant. Never pick up or carry a tree by its trunk, especially a balled-and-burlapped tree, due to the weight of the root ball. If they can’t be planted right away, water the trees well and place them in an area away from direct sun.

-Water a plant in a container before you take it out of the pot. After you remove the plant, cut any roots that circle the ball of soil (if the roots and soil don’t come out easily, cut the plastic away from the root ball. Don’t pull the plant out by its trunk). Use a sharp knife to make two or three vertical cuts, and gently loosen the ball to expose more roots to the soil.

-Place the plant in the hole so that the top of the root ball is an inch or two above the soil line. Remove any nails or rope lacing and cut away the burlap, leaving the burlap at the bottom of the root ball. If there is a wire basket, cut as much of it away as you can without disturbing the root ball.

– Backfill the hole with the soil that was removed from the hole, watering when the hole is about half full and again after you finish backfilling. Rake over the soil to even it out with the ground, and cover the area with 2 or 3 inches of mulch (keeping the mulch away from the shrub’s trunk.

-Don’t forget to provide water to newly planted shrubs and trees if the weather is dry.
