1. Quite early last spring my giant scabious starting growing a large number of big green leaves (loved by caterpillars). Flowers did not start to grow until summer which is normal I guess and grew to a lovely height. My question is can you safely give these an early 'chelsea chop' ? (not stopping the height just reducing the foliage a little, I hope). Unless all this foliage is quite normal. 2. After flowering how far back to you cut? Do you cut back to ground level or to the first leaf? 3. Do you leave the plant alone through winter as a lot of its leaves now I assume are dying off as they are going a funny colour and look awful? I've only been gardening a few years and have much to learn. If someone can give me a little guidance on these plants I would appreciate it. Thank you.
