Thuja Green Giant Evergreen
Please see attachment. Some of my Thuja green giant evergreens are splitting toward the bottom of the trunk. Do you know what is causing this? What can I do to alleviate this issue and hopefully save the trees? Should I spray it with pruning spray or tape? The trees were planted in March 2016 and were about 3 ft high at the time of planting. I appreciate any info you can provide. Thanks.
Hi. Thank you for your question. I am not sure why the trunks are cracking - there can be multiple reasons. (possibly the excessive rain received earlier in the season) We do not recommend spraying a sealant, etc. on it. I have provided a fact sheet that explains various reasons for bark splitting to occur and how you can trim the area and allow it to "heal"/callus around the area. Good luck! Tracy
