We grow 900+ dahlias each year at RainySunday. Cut flowers are available on farm in the summer and dahlia tubers are available in the winter (usually late January) and early spring from this website. All tubers sold are from dahlias grown here on our farm and are sold individually labeled and packaged in vermiculite. Tubers can be picked up on-farm or shipped nationwide. Dahlia tubers will ship in April 2023; if you need your tubers sooner, please add the "early ship" option to your cart. We do not use any synthetic fertilizers, pesticides or herbicides. We fertilize with compost, we control pests keeping plants as healthy as we can as well as picking off any unwanted critters by hand and encouraging a diverse ecosystem, and we weed with our hands and a hoe.
