![]() Live oaks: All foliage will be lost which would have been lost when the new foliage came out in spring anyway. Unfortunately fruit production will be limited. Open flowers and fat buds on blueberries, peaches, and pears froze, but the trees should be alive and sprout as normal. Once again, do nothing for now and prune back to live growth when they sprout. Most citrus above I-10 will have severe damage. Sagos aren’t true palms, are less cold hardy, and back then were only cold hardy from I-10 south.įruit trees: Most are cold hardy except avocado, citrus, pomegranates, olives, and figs which will have varying degrees of damage and death. Historically the only palms reliably cold hardy here in northeast Texas and the only ones to survive zero degrees in the 1980s were Mexican/Texas sabal palms, Brazoria palms, dwarf palmettos, and a number of windmill palms. It will take months to see if they resprout. Palm Trees and Sago “Palms”: Many will be damaged or dead but do nothing but cut off the dead fronds for now. Deciduous magnolias lost their flower buds but will be fine. Magnolias: Other than ice damage to southern magnolias, they appear to be fine like many native plants are. In the 1980s Lagerstroemia fauriei froze and died, ‘Natchez’ and many hybrids froze to the ground, and there were varying degrees of damage to most older indica cultivars. Don’t do anything until they start to sprout then cut back to where new growth is occurring, even it’s at the ground. Once you see the stems split open and the plants resprout, cut them back to that point, even if it’s at the ground.Ĭrapemyrtles: There will be different amounts of damage on different cultivars in different microclimates. English ivy may have had foliage damage only. Still others like coral vine and creeping fig may have been killed. Vines: Native vines like coral honeysuckle and crossvine may be just fine while others like Carolina jessamine and confederate jasmine may be damaged. Once you see which stems are brown/dead and which stems are green and resprouting, cut them back with loppers or hand pruners, sprinkle a bit of lawn fertilizer, and they should look nice again by fall. Hybrid teas, grandifloras, floribundas, polyanthas, and modern shrub roses like Knockouts and Drifts are considered more cold hardy while uniquely Southern roses like Teas, Chinas, Noisettes, Banksias, etc. At first glance it appears that many will freeze back to and resprout from the snow line. Roses: Many roses in Texas and the South have taken a severe hit and will have varying degrees of freeze damage. ![]() Most broadleaf evergreens prefer milder climates while narrow leafed evergreens and deciduous plants are more adapted to colder climates. Many of these plants are from milder parts of southeastern Asia and simply aren’t used to zero degrees. Split stems will be dead. There will most likely be no blooms this year and all old foliage will most likely fall off. It will take weeks or months to know the extent of the damage to our plants, if or when, they start to resprout and what part of the plant resprouts.Įvergreen Woody Shrubs (abelia, Asian jasmine, azaleas, banana shrub, camellias, eleagnus, fatsia, fig ivy, gardenias, Indian hawthorn, Japanese blueberry, ligustrum, loquat, loropetalum, oleander, pittosporum, privet, sasanquas, sweet olive, Texas sage, viburnum, wax myrtle, etc.): Wait until they start to resprout from the existing stems or the ground, then cut away dead and leave what is alive and growing. This particular species is best suited to well-drained soil because of this potential threat.Greg Grant, Texas A&M AgriLife Extension Service Planting Indian hawthorn in areas where water accumulates in the soil will encourage the growth of the disease. It is most likely to be a problem when temperatures are between 60 and 80 degrees Fahrenheit and the plant's leaves have been wet for an extended period of time, especially in the 12- to 24-hour range. The infected leaves of other plants spread the disease during wet weather. These spots often grow together to spread the infection to larger areas of the plant. This disease will generally only cause cosmetic damage to the plant, but severe infections can cause the hawthorn's leaves to fall off, making the shrub prone to future infections, and vulnerable to damage from the cold and the infestation of insects.Įntomosporium leaf spot can be recognized by the presence of maroon-colored splotches on the leaves. One of the biggest problems with Indian hawthorn is its common susceptibility to entomosporium leaf spot disease.
