Here's my two cents...I would do a curved bed. If you lay a hose down and make the shape you want. Then they say to
put something white (flour??) so you can follow the outline of your hose as you dig. Will 64 inches take in that Crepe Myrtle tree I see? I bet it will look great. You can add some clematis or roses to run up against your fence. Sarah

I also like curved beds. Just a personal preference.

I love the curved beds too. If you made a curved bed, it would look more attractive with the straight lines of stones around the pool. Marg

Curved bed for sure. Use cheap white spray paint to follow the hose and mark your lines.DO NOT crowd your DL's give plenty of room for air flow to reduce the chances of rust.
AND buy rust resistant fans!! Too hot and humid here for many cultivars and some are rust magnets.

Curved bed wins then! Thanks so much. The crape mrytles are gone, we are putting new trees in, nothing big. I don't know what kind yet, maybe Eastern Redbud.

Weldon, thanks for that tip! I got a lot of Daylilies from Three Creek gardens last weekend. What a fun trip!
