Tuck plants in for a cold winter nap



When the temperature bottoms out, many plants fall into such cold, hard times they don't bounce back. Before the temps hit sub-zero this weekend, however, there's still time to give these plants the TLC they need to survive the bitter cold.

Start by grabbing hold of Saturday to water the lawn one more time. Give plenty of water to slopes and south and west facing areas because these will be the driest areas. This moisture is not only good for the sod, but will also deal with mites that thrive in dry turf. Moisture is one of the best and easiest remedies for these pests. After watering, remember to un-hook the hose.

Next job: seek out your most tender plants to give them extra protection against the cold. Bear in mind that many of our low-water plants that thrive in the dry summer may not be cold hardy in near-zero temps.

To protect these plants, mulch the bases either with straw or shredded wood mulch. Straw and shredded mulch are loose and fluffy and less apt to create the wet and soggy conditions we need to avoid.

Common landscape plants to protect include:

• Grapes which need protection from the root crown and to about 18 inches up the canes. Because the mulch will be stacked high, wrap the pile with burlap to hold it in place.
• Other perennials such as: pansies, roses--including Meidiland and miniature roses, mums of the less cold-hardy varieties, hibiscus and some penstemon.
• Non-native or less hardy ornamental grasses such as Mexican feather grass, northern sea oats, Japanese forest grass, blood grass and pampas grass also need mulching, but the grasses will need to be cut down to about 6 to 12 inches before applying the mulch. Cover the mulch with burlap to keep it in place.

More about grasses. The more cold hardy grasses common in our landscapes include Karl Foerster and native grasses such as blue avena, blue fescue, little blue stem and switch grass. They are generally left uncut during the dormant season to provide winter interest. However, if grasses get broken down by heavy snow, you may need to be cut them back before spring.

Enjoy your Saturday outdoors before the deep freeze hits. As the thermometer drops, take heart in knowing that temps around zero eliminate certain landscape pests we're better off without. There's a warm silver lining in that cold, gray cloud!
