I have been successful in growing and blooming kalanchoe from cuttings but they grow tall. How do I make it grow shorter and compact with more branches? These are ones I planted last summer and have been sitting in my sunniest window this winter.
What you have is a Kalanchoe that has been allowed to grow without proper pruning. Kalanchoes require pruning in order to maintain their shape and to encourage blooming. Here is a helpful link with information on how to prune a Kalanchoe. Hope this helps and apologies for all the advertisements in the article.
