Feeding your hungry Clematis for beautiful and massive blooms....save banana peels, eggshells and tomato discards, put them in a blender with water, puree, then pour around the root areas. Clematis should be fed supplements like this from February through September.
How to Grow Clematis: A well-grown clematis in full flower is a sight to behold.... Clematis prefer moist, well-drained soil that’s neutral to slightly alkaline in pH. If your soil tends to be acidic, you should sweeten it periodically with limestone or a little wood ash. Companion plants, such as this pale-purple baptisia, keep the clematis' root-zone cool.
