They do bloom. I can never get mine to bloom either, but my sister has a same one and it blooms every year. It depends on how rich your soil is.
It probably is the soil, try adding some Epsom Salt to the area around your Climatis, being careful to not get it on the plant itself, it will burn it. The Epsom Salt is magnesium sulfate and is a valuable mineral many plants need. See if this helps.
Thank you, I'll try this and see if it helps.
Hi Kirsty. I'm Cindy. Dissolve one tablespoon of Epson Salt in a gallon of water. Sprinkle this solution on the soil at the base of your Clematis. Then put more water in the same spot. The additional water will help the roots receive the Epson Salt. You can repeat every two weeks. You should see improvement in just a few weeks. You can use this solution for any of your outdoor plants, including the vegetable garden. Good luck Kirsty and Happy Holidays.
Thank you Cindy and Happy Holidays to you and yours too.
