The Monthly Gardner – February 2013

pruneing-rose
Where to prune a rose.

This has been an unusually cold and wet winter, which means that while January is the ideal time to prune, February is still a good time to get those shears out and prune what you probably did not do last month. But don’t wait till March, particularly if the weather turns hot and dry. And keep up with the harvest of cool-season crops, such as peas, lettuces, and spinach. It will encourage more production.

Pruning

Roses can still be pruned. Take out all crossing canes, dead canes, or any that look diseased. If any canes have grown below the graft union or bud union, get rid of them. And prune mature bushes to around 18 to 20 inches in height.

Cut back woody and overgrown perennials. If in doubt, look at the base of the plant. If it is sending up fresh growth there, you can safely cut off the dead or old plant material now. Cut back old foliage from ornamental grasses, liriope (monkey grass) and mondo grass to just a few inches high. And evergreens may still be pruned, but avoid pruning them later on this spring and summer.

 Bare-root Planting

Now is the perfect time for bare-root planting (plants without a root ball) There’s a whole host of bare-root plants available through mail order, but if you’re buying locally, roses, berry bushes, artichokes and ornamental trees should be available. For information on how to go about planting bare-root stock, also know as dry-root, check out my January 17, 2012 blog on the subject.

 Fertilizers

Fertilize roses and perennials at the end of the month and keep them watered. You can use chemical fertilizers (follow package directions on amount and frequency) or organic fertilizers, such as compost, fish emulsion, and others.

In the low desert and other hot areas, feed citrus, avocado, and deciduous trees now, but wait till next month in cooler coastal or higher zones.

Weed Killer

To greatly reduce weeds, apply a pre-emergent weed killer to beds and borders. It works by preventing seeds from germinating, so don’t apply anywhere you’re planting seeds.

The Monthly Gardner – March

Facebooktwittergoogle_pluslinkedinrssyoutubeFacebooktwittergoogle_pluslinkedinrssyoutubeby feather

March and April are the ideal times to get your garden planted. This includes most summer annuals and perennials, warm-season and cool-season lawns, some cool-season and warm-season vegetables, and almost all permanent garden plants, such as trees, shrubs, ground covers and vines. But I would hold off planting tropicals for a couple of months until the weather warms up. So get in gear and get your garden in shape!

And since there is so much that needs to be done, here is list of things you should consider:

Purchase & Plant:

  • Drought-resistant plants
  • Trees, shrubs, vines, ground covers
  • Flowerbeds with warm-season flowers
  • Perennials
  • Tigridias, gladioli, tuberous begonias
  • Cuttings: herbaceous and softwood
  • Citrus, avocado and macadamia trees
  • Fuchsias from cuttings
  • Lawns
  • Summer vegetables plus green beans, potatoes, artichokes, tomatoes, culinary hers and edible flowers

Trim, Prune, Mow, Divide:

  • Prune begonias, cannas, ginger, ivy, pyracantha and Sprenger fern
  • Dethatch warm-season lawns
  • Deadhead annual and perennial flowers
  • Tie into knots the floppy leaves of bulbs until they turn brown
  • Prune camellias, tropical hibiscus and epidendrum
  • Pinch fuchsias to make them bushy
  • Propagate bamboo
  • Mow all grass lawns

Fertilize

  • Citrus trees, avocado trees and macadamia trees
  • Fuchsias
  • Ornamental trees, bushes, lawns and ground covers
  • Container-grown flowers with liquid fertilizer
  • Cool season flowers if growth slows
  • Roses
  • All lawns
  • Treat blue hydrangeas with aluminum sulfate.

Water (when there isn’t sufficient rain)

  • All garden plants according to their needs
  • Fuchsias
  • Roses
  • Spring-flowering bulbs
  • Don’t let azaleas dry out

Control of Pests, Diseases & Weeds

  • Control slugs and snails
  • Check roses for pests and diseases
  • Control cutworms
  • Pull weeds
  • Spray cycads for scale
  • Control giant whitefly

Do Something Special

  • Plant herbs in a window box or garden

December’s Gardening Tips

Facebooktwittergoogle_pluslinkedinrssyoutubeFacebooktwittergoogle_pluslinkedinrssyoutubeby feather

Here are few suggestions:

Tulips

Transplant: it’s a great time to transplant, but be sure to keep new transplants well-watered if the weather is mild and dry. In warmer regions, now through February, after a killing freeze or a frost, is a good time to move a rose. Transplant it with as much of the roots as possible and keep well-watered.

Roses: don’t fertilize or water roses this month. they need to harden off for winter.

Bulbs: plant pre-chilled spring bulbs, such as tulips and hyacinths.

Plant: bare-root trees, shrubs, roses, and vegetables such as artichokes, asparagus, beets, broccoli, Brussels sprouts, cabbage, carrots, cauliflower, celery, greens, kale, kohlrabi, lettuce, peas, potatoes, and radishes now.

Hyacinths

Prune: deciduous fruit trees once they’ve gone dormant and dropped their leaves.

Smart Pruning

  • In those areas where frosts are just an occasional thing, keep plantings well-watered so whenever a freeze threatens, plants are more likely to survive. A “turgid” well-hydrated plant is better-equipped to recover than a dehydrated plant.
  • If a plant is damaged by frost, resist the urge to prune the damaged parts. They may well protect the rest of the plant during the next frost.
  • Cut back dormant grapevines. A bonus: The cuttings make great wreaths!
  • Stimulate wisteria by cutting it back now. Cut back the long, thin branches that appeared this season alongside or entangled with the older wood. Leave two or three buds at the base of the branch.

Lawn: if you’ve overseeded your lawn and there are bare spots, feel free to scatter a bit more seed to fill in. Also, if the weather is warm and dry, you may need to water the lawn.

Happy gardening.
