They're only babies!!!
When you purchase a plant you are not buying an inanmate object. You are adopting a living thing. The plants you buy at a nursery (why do you think they call them that?) are young plants and will grow if allowed to do so, into a beautiful mature plant. Would you adopt a child and expect it to fit ito a crib 10 years later? PLEASE give your baby room to grow!! know before you bring it home what its mature size will be. If the Mature size is larger than you want SELECT AOTHER VARIETY!!! You can't turn a rotwieller into a toy poodle! If you attempt to keep a plant that was meant to be 10 feet tall trimmed to 3 feet, you will cause yourself a lot of work, with very poor results, and have a mutilated, unhealthy plant. Would you cut off your child's head because you wish he were shorter?!

Create a beautiful place
A landscape is a work of art that grows more beautiful with age. Plan for your plant's growth and allow ample room when you plant it for it to reach its full mature size. Better to look a little sparse at first than to have an overgrown mess later!! Fill in any blank spaces in your young place with annuals, and reduce the number of annuals each year as your beautiful place matures. Its easy to arrange a few plants and make it look good when you plant it. Time is the test of a good landscape. Plan ahead!! Know what plant you are buying, and how large it will become. Create a beautiful place, that will always be beautiful!!
