Today and tomorrow the Dallas Arboretum staffers are busy planting bulbs snug in the grounds and covering them with petunias. As the below-freezing temperatures approach Saturday night, here are some suggestions from Dallas Arboretum VP of Gardens Dave Forehand,
- Water before it freezes: Watering material before the threat of frost protects the plant root zone. Water acts like a blanket insulating the roots. This makes the plant stronger against a freeze. When plant cells are full of water, they are less likely to be subject to frost damage. If possible, water a day or two before a freeze and make sure to water the entire root zone of the plant. This is especially important in newly planted trees and shrubs. Try watering early in the day so plants have time to absorb water before a freeze. If at all possible, avoid watering the foliage. If you have an irrigation system, hand watering might be the best option for certain locations. Keeping water off the foliage prevents the formation of ice on leaf material which can cause breaks and more damage.
- Use frost cloth: Frost cloth acts as a blanket and helps trap heat. Make sure that you secure the cloth entirely around the plant and tighten to the soil using fabric pins or bricks (anything that will hold it down firmly will work). Frost cloth is made from a product that “breathes,” and this cloth helps against burn caused by other materials. Purchase frost cloth months in advance. When the threat of a freeze is coming, frost cloth sells out quickly. Do not use frost cloth when there is a chance of snow. Otherwise, it will cause more damage breaking plants from the weight of the snow.
- Check plant health: The healthier your plants are, the more prone they are to handle stress. Proper water and maintenance throughout the growing season will help in the winter months. It is also important to select the right plant for your area. Check to make sure that the plant material you select is appropriate for your location. Check out USDA plant hardiness zone map to see what zone you live in. This information will help you purchase the best plant material for your zone.
So, if you’ve finished your uber shopping, then why not take advantage of this advice from a man-who-knows? Come spring you’ll be the standout among your neighborhood of cottages.
