I planted some saplings approximately 12" tall in the spring of 2018 near my pond during a really dry year here in North Texas.

Since 2000 it has reproduced numerous progeny throughout the neighboring forest. But it was not phased at all, and has healed over since and never slowed its growth. The big DR that I am standing beside the trunk, was struck by lightning around ten years ago, leaving a scar almost to the ground. I posted some pics of some of my favorite local middle TN DR's. If you push for extreme buttress and distorted base with dominant low limbs, then height growth may be less than I stated in my table. Then commensurately lowering for future years. My 50 years of records and studies reveal that in TN, on an average to good site, you should expect these growth rates : Likes moist well drained soil just like most trees. If growing an individual specimen tree, never trim branches above thigh high.
Give full sun and perimeter room to grow. I have five here at my estate Arboretum (Two are the Goldrush / Ogon types. My biggest DR now approaches 90 feet high and 3 feet dbh. Since then I have studied and planted many in Tennessee. Even in 1967 this tree was over 60' even though it hadn't been brought to USA but a couple decades. Seeds given to Vanderbilt University in Nashville, one of which was planted near my home, in the late 1940’s. In 1967 I regularly watched and studied one of the first Dawn Redwoods planted in the U S A. Studying and growing the species since 1967.

More watering is not required because no moisture evaporates through the ziplock bag. įill in the ziplock bag as much tap water with a few drops of universal fertilizer, so that after the absorption of the substrate a few mm of water remain on the bottom. Then put the plastic pot in a ziplock bag - with a pot size of 6 cm, a ziplock bag of size 12 x 17 cm is recommended. Sow the seeds on the peat pellets and cover the seeds with a thin layer of peat (about 2 mm).
