How do you get your hydrangeas to bloom?

Answer 1

Pruning has a lot to do with flowering. For Mophead hydrangeas, cut out 1/3 of the thickest, oldest stems at ground level, leaving the youngest, healthiest canes. Prune tips of remaining young current growth by about 1/4, back to a pair of healthy fat buds. Water deeply. Hortensia and Lacecap hydrangeas flower on new stems that sprout from the previous season's growth. Lightly prune in winter back to just above a plump pair of buds. In frosty areas, do this after the last frost. Hydrangeas like morning sun or filtered light for the full day. The soil pH needs to be between 4.5 and 7.5 or plants will suffer dramatically.

Answer 2

SOLUTIONS For growing Hydrangea macrophylla and Hydrangea macrophylla var. serrata types in zones 4 and 5. I got this from the web and it really works!!! The following solutions have been tested successfully in Michigan and Maine’s northern interior since 1993. Don't prune unless necessary. Pruning often removes the flower buds. If you need to prune, remove any dead stems in the spring. Any other necessary pruning should take place immediately after bloom. The new flower buds form in autumn, when night temperatures consistently drop below 60 degrees. Cover the plants to a depth of at least 12-18 inches with mulch, bark, oak leaves, pine needles, or straw. Cover the entire plant, tips included, if possible. Remember not to use maple leaves because they will mat when wet and can suffocate the plant. Some people make cages out of snow fence or chicken wire to hold the mulch. One creative gentleman, who every year has a spectacular Hydrangea garden, uses 20 gallon plastic trash cans. He cuts off the bottoms, places them over his plants in early winter, fills them with mulch and then puts the lid on them until spring. . Remove the mulch only after any major threat of frost (50% frost-free date) has passed. For the Mid-West Michigan that is around May 15th. Do not be concerned if there are small white leaves and stems they will survive and turn green again quickly.

Answer 3

Usually pruning at the wrong time is the major cause of hydrangheas not blooming.

The flower buds are formed in the previous year so leave the plant alone for two years. If this is not the problem give it a feed with high potash feed.
