my newly planted outdoor plants are brittle,and turning brown at the base what can i do ?

Answer 1

Did you mulch around them? Mulching helps to retain moisture.

Answer 2

If you didn't amend the soil so that it can retain some moisture your plants are probably dying of thirst, no matter how much you water. Try digging them back up and putting them in buckets of water or a small wading pool if you have lots of them, then add peat and manure to the soil, digging it in well so it's well mixed or using a tiller for this if you can, then replant early in the morning or in the evening after 6pm so the plants have a chance to adjust a little before the full heat of the sun hits them again. Fill the holes you dig half way with water and let it soak in before putting plant in. You may also need to trim about an inch off the roots before replanting because the root-ends are probably damaged and your plant needs healthy root in contact with soil and moisture to survive and flourish. If the roots seem very tight and bound, I loosen them up with a knife and then spread them out some with my hands so they have a better chance of spreading into the soil for nutrients and moisture. As a rule of thumb, do not plant the plant any deeper then it was in it's pot, or if you do, no more than an inch or so depending on size. Plants can also "drown" when too deep or in soil which is too heavy because they can't get enough air. Also, double-check that the things you planted are in the proper light, IE: are they best in full sun or do they need some shade? A shade loving plant will die in the sun no matter what you do.
