Artist Frances Palmer, famous for her vases and pottery, is also a passionate dahlia gardener. May is a great time to plant dahlia tubers and Palmer gives step-by-step instructions, along with photos of her beautiful dahlia garden in bloom and her beautiful vases.
Select a spot in your garden with well-balanced and composted soil that receives full sun throughout the day. In my garden, I use tomato cages and wooden stakes to hold the dahlias as they grow. I purchase these at Home Depot, but most garden stores will have them as well.
Place the cage in the ground first and then drive in two or three stakes per plant/cage.
