I have an area in my house that is collecting lot of rain water. I thought of french drain and sump pump. But the location is long way away from storm drain.

Now I'm thinking of rain garden. Anyone have done this? Is this even a good idea?

Looked into it. Have what I think is a nice little consumer reference, how to, book “Rain Gardening in the South” Helen Kraus & Anne Spafford, horticultural profs at NC State. Where you located? In Baton Rouge, Hill Top Arboretum has demo rain garden. If you are near an arboretum they might have one. I think it’s a good idea if done properly.

Yeah very close to hilltop. They are probably closed due to coronavirus

From the Houston Chronicle:

quote:

For your rain garden

Flowering plants: Turk's cap, Mexican petunia (ruellia), black-eyed Susan, yarrow, swamp milkweed, butterfly weed, canna, purple coneflower, daylily, spider lily, swamp ginger, Mexican mint marigold, lamb's ear, bee balm, 'Red Star' hibiscus, and a few varieties of iris including Louisiana and bearded

Shrubs and small trees: American beauty berry, yaupon, dwarf palmetto, possumhaw holly and Southern wax myrtle

Big trees: Southern swamp maple, river birch, bald cypress, pawpaw, and various native hawthorns.

Other plants: Many ornamental and native grasses do well in rain gardens, such as switchgrass, Indian grass and sedge. crossvine and Carolina jessamine work in both wet and dry conditions.


I might try this since I've got a really low spot that holds several inches of water.
Is the idea that I don't build it up at all??

The book I referenced goes into this in detail but because it was written by a couple NC State University profs, I checked NC State’s website to see if they might have a fact sheet and found this nice 12 page fact sheet Backyard Rain Garden. I think it should answer your questions.

A rain garden is meant to be a temporarily impoundment to water until it can seep into the soil, evaporate, and be used by the plants. I know if I were to build one in my yard, with the heavy clay soils I have I’d be looking at a 3 day+ water retention planting scenario described in the fact sheet.

Ultimately I didn’t build one as I determined I could move water off the lawn with some relatively simple grading, and and a couple sub-surface drain lines and I already had a sub-surface drain to the street I could tie into.

But I like the idea, it’s a simple, practical concept, and I came close to making one. Certainly might be a practical alternative to some.

I don’t have a way to tie into drains without going 100 feet of digging. That’s the main reason I’m considering the rain garden. Thank you for the material Crawdude

That's a great material. It even lays out the plants you want to plant :bow:
