Sorry, but it's kind of late to be thinking of turning a mess into a beauty in one month. How about heavy weeding, shape pruning (or at least trimming straggly plants, mulching and pots and pots of mums (you may want order the mums so you will have them closer to the date or ask if the nursery will hold them), what about boston ferns (do you have friends with hanging ferns you could set on pedestals or hang if someplace available. Have you thought about pansies, ornamental kales, etc for borders. There must be other nurseries that you could check out for cheaper plants, check the yellow pages.

Good luck, and if the brides pretty whose going to be looking at the landscape.

It is sort of late for you to start on a project like that. I did our grandaughter's place for her wedding, and it took me a month. I did everything in planters, except a few flowers from my yard that I transplanted, shasta daisys. Call the local nurseries there, many are having sales just to get rid of plants. At least here in Wa. they are, every nursery has half off, 75% off. I guess we are of no help! I would try to get plants in pots. Also I had some extra silk flowers, and I stuck them in the pots with greenery, and all of the people thought that they were real. Colored pumpkins are in, maybe you could use some of those.
