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 MorePictures of Oakleaf hydrangeas in bloom
Comments (9)"cearbhalll -- how old is your oakleaf?" It was installed in a different location in '09 where it received light from one direction only. It kept growing so lop sided that I kept pruning it to shape so it never grew to much size. It was from Rare Find and purchased as a two gallon IIRC. In 2012 I moved it to this larger spot where it seems to grow in a bit more balanced form- it still faces the rising sun but not as badly and I've been able to stop pruning/ruining it. It's fall color is outstanding and I especially love the mint green color of the new leaves in the spring....See MoreBig leaf hydrangeas not blooming
Comments (7)"One person I've talked to said we hadn't had cold enough winters, and there was nothing I could do about it," LOL!! Well, that's a new one :-)) That person must not be at all familiar with hydrangeas and how they bloom as it's not ever a case of the winters being not cold enough - these plants grow and flower in such mild winter climates as SoCal and the Gulf states, even parts of Mexico - but it could certainly be a case of the winters being too cold. The vast majority of bigleaf hydrangeas set their flower buds in late summer/early fall for the following year so the winter temperatures really have nothing to do with bud formation. But severe winter temperatures can destroy these latent buds, as can late winter or spring freezes. So cold winter temps can affect how well these plants bloom and you can do something to prevent this cold damage. Many folks in colder zones (below 7) will provide winter protection for their hydrangeas to ward against cold damage. If you search through the older threads on this forum, you will get many suggestions and methods on how to accomplish this. And since we don't know where you are located and if cold damage is the reason for lack of flowering, I would also add that pruning at the wrong time or too severely can also have the effect of removing the latent flower buds....See More3 Hydrangeas not blooming
Comments (12)Hydrangeas that bloom only on new wood are either paniculatas (Pee Gee-like)or arborescens (Annabelle-like). Pink Elf only blooms on old wood. Not sure why the blooming difference vis-a-vis Endless Summer and Everlasting. Make sure you are not over feeding them as too much fertilizer will result in nice green leaves but few or no blooms (one application of fertilizers or even none is all they need in Spring; new ones already have round fertilizer pellets so you can skip fertilizing on Year 1). Most paniculatas and all arborescens bloom on new wood and have no problems if winter is harsh. Of course, their blooms are different (paniculatas) and they have no blue or purple blooms....See MoreHU-617311725
