    This is a landscape job that I did last summer. The Fire pwr Nandinas at the front of the bed are dieing dew to poor drainage. That down spout had a flex pipe installed the next day after the job was complete, and it extends out into the yard about 2 feet past the bed. The soil here sucks, it was all clay and I tilled in compost and topsoil. The boxwoods are doing fine. Yesterday I pulled up the Nandinas and there was about 4 inches of water standing in the holes. So, when I made this bed in the clay, I basiclly created a catch basin that will not drain. This is what I am thinking needs to be done, and please tell me if it is the correct way to address this problem. Pull all the plants out, put a corrugated pipe underground at the front of the bed and raise the bed with Pete or sand tilled in? Not sure which or both. Then do I need to run laterals T-ing off out into the yard or into like a french drain? Thanks for any input.:help:

    I don't know if I read this all correctly since I'm 1/2 asleep but how about putting in a pop-up drain ($10) from Lowe's to get the water away. When you plant the new FP dig the hole about 1 1/2 - 2ft deep and will with composted topsoil mix......its all fertile and the water will drain below the roots. Or like you said, mound each plant up a little.

    Don't know if you can read that or not, but you will have to extend that drain and get the water out and away from the area. Even if you raise the bed the water will still sit there under it. Do not add sand!

    Hard for me to tell which way the yard is graded to drain at the sides.

    Tthomas has a good idea , but you indicated that you already extended the downspout beyond the bed - that may not be the source of the standing water . I would try your idea of a french drain across the front of the bed and tee off into the yard into a gravel basin - then raise the nandinas up by building up the bed .

    looks to me that you are traping the water behind the mound you have made. i think that you may be better off just putting a few small pipes from the back of the mulch to the frount. i ran in to this problem once when we did a planting in front of a comercial building and they had latace under the deck and i was unable to fill dirt in behind the latice.
