I need some ideas and plants to put on my 2 crepemrtle trees. I have they are bare on the bottom and need some colorful plants. It gets full sun 10 hours. Some colorful plants that will last till fall if possible. My 2nd question is how to make a bed for my crepe, cause im going to add the plants. I need the basics on how to prepare a bed?Do i use a spade to dig the grass? How much to dig off the grass. Do i use some kind of weedkiller for the weeds, or newspaper etc. Any ideas on how to prepare for my garden bed? I want to make a perfect circle around my crepemyrtle tree to start.
