Best time to prune ornamental cherry
Comments (9)Katrina, the 'best' time for nearly all tree pruning is dormant season, late dormant season to be exact. But, the difference between the 'best' and 'worst' times is not huge. Don't get too stressed about that factor. If one simply avoids pruning when A) The tree is making leaves, ie. Spring, or B) the tree is shedding its leaves, ie. Fall, everything will be fine. And those 1/2 inch thick branches are by no means too large for the tree to handle having them removed. The idea that a flowering tree should be pruned right after flowering is that by so doing, you are not removing flower buds for next year. This is true, but it is far outweighed by other advantages of dormant-season pruning. These are: You can see the structure better, you are allowing the tree to have open wounds for the least amount of time before resumption of growth in Spring, the plant will be poised to put its energy into the branches you leave on the tree and will not have wasted energy in producing leaves only to have them cut off, and finally, disease pressure is usually lower at this time of year. FWIW, the organization I work for manages perhaps thirty to forty thousand individual trees. We prune year round, out of necessity, avoiding only those two times mentioned above. There are a few individual variances we follow as well. We prune no oaks during during growing season, as this can open up the plant to oak wilt. We prune no honey locusts on wet days, as this can set the stage for nectria canker development, and any shearing-type pruning such as Japanese yew hedges are done in summer, no later than August, so the wounds can close before winter, thereby avoiding dessication of the cut stems. But otherwise, you really do have a large window during which the pruning can safely (For the tree) be done. There may be a difference from one region to another in terms of pathogens and host susceptability, but at least where I do my work, I wouldn't think twice about whether or not to prune a cherry, or any other ornamental tree, during late winter. I don't wish to come across like mine is the last word on the subject, but I can state unequivocably that I've done literally thousands of such prunings with no harm done to the plants.

Comments (246)Here I am to keep the thread alive! First, thank you to all who've posted because while I did know the pencil cactus was poisonous, I didn't realize just how dangerous it could be if the sap got into my eyes. That said, I just purchased a large pencil cactus today that needs to be repotted. I don't have any pets or kids, so no concerns there, and I've already warned my husband. I'll definitely be wearing disposable gloves and protective eyewear just in case. @ Kevin Dondrea Also, peanut butter has been banned in plenty of schools... I don't know if you were being sarcastic? @ Larry WestCoast, You really had me going with that astroturf bit :D All in all, a good reminder to be vigilant with the plants around us. I'm a plant enthusiast, and even I sometimes forget to pay attention to the potential threats and dangers of different species. I'm obviously not eating any unidentified plants, but from now on I'll be more vigilant about wearing gloves and immediately washing my hands after yard work too....See Morehave: san antonio plant swap (saps) october 12, 2013
Comments (149)I had a great time on Saturday. I loved meeting everyone. Thank you all for your generosity. My husband wanted to stop and watch a movie as soon as we left the park. Ugh! I looked and smelled ferocious, but we stopped and watched Captain Phillips. Awesome movie. We took our time driving back and stopped and had dinner. All in all, we had a great day. Thanks again everyone! I worked in the yard all day yesterday. My body is paying for it today at work! Thank goodness I'm not busy. Can't wait until the next plant swap. See you then!

Comments (5)Probably will fluctuate with trunk temperature and/or the amount of water available to the roots for take-up. If it were my tree, I'd not do anything with sealer at this time of year unless in a neighborhood where oak wilt has been a serious problem. Wounds over 3 or 4 days old are SUPPOSEDLY not susceptible to wilt spores delivered by sap-feeding (nitidulid) beetles. If seeping is due to a poor cut, pruning sealer could further hamper your tree's efforts to isolate the damage. It's young, so should be able to eventually get it done as it grows. Might reconsider pruning sealer if it's still seeping when the beetles enter their most active period again next February. However, would try white glue or latex paint before resorting to the tar-like sealers....See Morepoaky1
