general outdoor plants tend to wilt a small bit
anyway during the summer months. If you want to
really make sure that your plant has a water
source underneath it, simply dig a small hole
about a foot deep to the side of your plant but
keep an eye out that you do not hit any major
roots. Put your hand down inside the hole, does
it feel dry? Or does it feel cool and moist? If
it is cold and moist then the soil has stored
some water below the surface. Your plants can
drink this without problems.
