How and when to prune Endless Summers
Comments (16)Its interesting when you all describe the size of ES. I was at a lecture this summer with Michael Dirr who comercialized the ES. I have to move mine since it has outgrown its space. When I told him that mine was currently over 5 ft( july 10th) tall, he seemed startled and autographed his book on Hydrangeas with this," Endless Summer sounds too good to be true;A tree? No way! At any rate now I need to transplant it and the question is can I do it in the fall? I don't want to lose it but I keep thinking I might do more damage when the warm weather starts it growing again. I also have to move an Annabelle ( actually give it away) and cannot wait for frost. What are its chances if I cut it back to the ground now instead of waiting for a hard frost that will be a month from now or more...See More'Rozanne' geranium and 'Endless Summer' hydrangea--how'd they do?
Comments (29)Hi, I just wanted to add to the ESummer discussion. I am surprised about dissatisfaction with the color etc. I love the mophead hydrangeas and not having been able to keep one flowering in my yard before was a great disappointment to me. So I was delighted with the Endless Summer I had last year. It bloomed a lot and my blue flowers were a fine color blue to me, in an unamended clay/loam soil with a ph of 6.4. It was a vigorous grower and the leaves were healthy all summer. It was placed in morning sun only just under the dripline of a silver maple tree. No wilt despite two months of barely any rain but supplemental watering and lots of heat last summer. I added an oakleaf hydrangea to the yard last year, and it died back to the ground over the winter and I have one little sprout just barely up. The ES on the other hand has a bushy 8" growth covered with healthy green leaves. So if the ESummer blooms again and stays healthy for me, I will be very grateful to have a dependable mophead in the garden with pretty blue flowers. I will try to remember to come back to this thread later when the plant blooms and post a photo of it. :-)...See More"Endless Summer" doesn't bloom, zone 5
Comments (22)I have had an Endless Summer hydrangea in my front shrub border since the first year it was introduced.... 10 years??. I like to refer to it as Endless Frustration. The plant itself is huge... Close to 5' tall and at least as wide... But it rarely has more than a couple blooms on it each summer. I only leave it there because, even with very few blooms, it is still a beautiful shrub. Large, dark green leaves... Nicely rounded shape. I tried an experiment a couple years ago. I took cuttings off the mother plant in September. Rooted them in jumbo four packs... Left them outside well into the fall to experience enough cold to lose their leaves and go dormant. At that time I put them on a basement window sill. Because the window is single pane glass it stays quite chilly all winter long, but doesn't freeze. In late March or early April, I pot the cuttings into 8-10" terra cotta pots... Three cutting per pot... And put them outside in a protected area... Protecting from frost if needed. I add some aluminum sulphate to the soil to acidify it and insure blue flowers. I water regularly and keep them in a fairly sunny area. By early June I have pots of gorgeous blue hydrangeas to place around the yard and enjoy all summer. Yes, it's a little bit of work, but nothing difficult... I'm a plant geek and enjoy doing stuff like this. My original planting of ES may be a floral disappointment, but this way I get to enjoy sumptuous blue hydrangeas every year. I attach a pic so you all can see how lovely they turn out....See MorePlz Help to decide between Quickfire & Endless summer Hydrangeas Zone5
Comments (17)Bobo has become my favorite hydrangeas for the last 2 years. I have 2 planted in a full sun location in the fall of 2013, as 2 quarts (~ 1 ft tall) small plants ordered online since local stores did not carry them yet. Both gave nice and long blooms in 2014, and have been doing great ever since. The size is much more compact (~ 3'x3') so this is a big plus for my small chicago area lot. In spring time, I only sprinkle a little bit (1 tbs per palnt) of Miracle-Gro® Shake 'N Feed® All Purpose Continuous Release Plant Food. There are several kinds, I use the one with NPK 10-10-10. I don't typically use fertilizer but rely mostly on mulching well. I agree with NHBabs that these H. paniculatas need to have more sun for best performance. Mine is planted in the same full sun bed with cone flowers, Phlox and black eye Susan. I almost never water them so Bobo endures the summer heat and drought just as well as cone flowers, etc. I did notice that my neighbor's little Lime blooms much less as they are in a partial shade locations than my limelights (full sun). I understand the fun sun in zone 5 (chicago) may be different from other areas....See Moremarciaz3 Tropical 3 Northwestern Ontario
