Houston Corymbia ptychocarpas Spring report and cold hardiness
Posted by Tom on 5/17/2010, 6:28 pm
The 8 or so ptychocarpas overlooking a pond on acerage on Tavenor Lane were frozen to the ground this winter, but are now putting out 20-30 vigorous sprouts each from the lignotuber,each approximately 2-3 feet high.The only limiting factors on how high these shoots grow this season is the amount of water (rain) they get,and the arrival of the first frost in October/November.
In the ground approximately 6 years , they were 2-6 inches caliper and 12-16 feet high and flowered prolifically.I don't have exact data ,but I think Houston's official low was 20 degrees,with maybe a 23 and three 25's thrown in.
The 20 or so Eucalyptus robustas on this property are still 50 percent defoliated and most had 3-4 feet of top kill on 25 foot trees.However, there are a couple of larger robustas that show little or no damage from this 20 degree event.
There are also a dozen or so E. camaldulensis on this property and these show very little if any damage.
