Endless Summer Hydrangea not blooming (zone 3A)
Comments (10)@luis_pr Thank you so very much for the info! I have seen people plant ES on the ground in the spring and dig up and put in a pot and bring inside for the winter. For me, it is almost not possible. 1, the plants are very big now, 3 ft wide and tall, as I bought the 4 gallon ones in the spring. oh well. 2, too much trouble for me and too much shock for the plant. 3, i dont have indoor space and big enough window to give them the light to keep them happy insdie. Artificial light is too much set up again. SO after some search, i will be use the cardboard box method, i think. Here are tentative steps: please help me better this process if something wrong in the procedure lol. Zone 3/4, Edmonton 1) After tree leaves fall, collect leaves in plastic bags. 2) When ES hydrangea leaves are brown and dried, covered them with a cardboard box, fill in dried leaves. 3) Tape the top of the cardboard box, to seal. 4) Secure the bottom with rocks or garden staples. 5) Wrap the box with brown burlap. 6) Wrap again the box with black landscape fabric, to absorb warmth from the sun. 7) Sit for the winter to be over, hopefully lots of snow cover. 8) Remove protection around last spring frost, on May 15 ish. 9) If Frost come back after the fact. using white drop cloth for temporary cover. I also attached a pic of my blue ES (the original) in my yard this year. Isn't this blue out of this world!...See MoreEncourage Endless Summer Hydrangea Growth??? (Z6)
Comments (12)Breeze - Mulch to the top and then some (if you can within aesthetics if it's in the front of the house). And or burlap wrap it, etc. GG - The interior stems of my plantings are supported by adjacent stems . Flopping of heavy heads on the exterior perimeter stems and some of the interior one where the shrub looks splayed down the middle Question. If one doe not deadhead or stake, what would be best practice if the goal is to let these stems remain vertical 365 days of the year.... My experience when I leave them alone and let the bloom weight it down, they don't exactly bounce back vertical. Some harden to a horizontal plane. Some develop this nasty horizontal bend and then this wicked U bend back vertical....See MoreEndless Summer hydrangeas don't bloom any more ...
Comments (9)Hello, jillkins. Yes, in Zones 4 and 5, ES is known in the forum for having blooming reliability issues.... not everyone though... for some people. They are described as being root hardy only in posts. They did ok for me until I killed the one by accident. The way these re-bloomers work: like all mopheads in the north, these hydrangeas develop invisible flower buds in very late Summer or early Fall; these then open in the Spring if winter does not kill the stems; you can prune the stems down if the stems do not leaf out by the end of May; keep any live stems if you winter protect the plants and the stems survive winter; the new growth that comes up in Spring is supposed to also to produce flower buds & bloom, provided the new stems get tall and old enough. That normally occurs in mid to late Summer. Soon after the flower buds develop, the buds open and go thru the broccoli phase and bloom. Now, anything that can interfere with that process can throw a monkey wrench into the "system". The weather (early winter, dry weather, etc), pruning, allowing the soil to go dry in the Summer, etc .... all those things can cause a problem or prevent the plant stems from getting tall or old enough to develop flower buds & bloom. The Let's Dance Series is another one that includes re-blooming hydrangeas but these are more compact so, I speculate, that their stems may get to the proper height and age faster and thus they may be more reliable re-bloomers in the Summer for you. If you want to try them out that is. Not sure if hydrangeas are out of stock for you locally but it is a suggestion. ;o) Other things to keep in mind in no special order: hydrangeas like uniform moisture in the Summer so try not to have dry soil (in the Summer) as this may trigger the shrub to kill flower buds and flowers; maintain 2-4" of mulch to reduce the need for lots of water and protect the roots from temperature extremes in winter and summer; fertilize only once in Spring, unless you live in the extreme South (too much fertilizing = too much nitrogen = green leaves = no or few blooms). Rule out deer, bunnies, squirrels as these all like to eat flower buds....See MoreHydrangea Endless Summer "Summer Crush"
Comments (62)Is it a heated garage? Did you water it while dormant? Sorry @luis_pr for the delay in replying. The garage is not heated (the coldest I observed inside the garage was -12 C/10 F while it was -22 C/-8 F outside) and the only water it got was from 'clumps' of snow that I would put on it every once and awhile through the winter. So here it was on May 17: And today, about 6 weeks later: I can tell you that it looks lots larger than it actually is, but clearly it is producing flowers (on strictly new wood)....See MoreMolly D.
