What plants would grow in an 18" X 3' deep hole drilled through limestone rock, 50 miles s. of Ft. Worth, Tx?

Answer 1

Well, first you would need to test the hole and see how it drains. If the water drains off fairly quickly then you could use the hole as a type of planter and for annuals or a small perennial. It would also be a great place to grow Chives or Mints since it would limit the invasiveness of them. Another plant you might consider is a Hardy Hibiscus.

Good Luck

Answer 2

Here are just a few Texas plants to look into. If it were me, I'd dump some Miracle-Gro potting soil which has plant food added to it into the hole. Mix in some Osmocote slow-release fertilizer and water well. Follow the measuring directions on the bottle. MAKE SURE THERE IS GOOD DRAINAGE before planting anything.

Answer 3

If you can put in really good soil in the holes , you can grow almost any native Texas plants. There are so many , I can't list them but you can do a search . It depends on the amount of sun also so don't forget to check that out.

Answer 4

Most any plant will grow. Just remember to keep it watered. You might think of a low maintenance plant such as the Texas sage.
