Answer: I think your plant would probably have done better if you had replanted in the ground immediately. Now that it has been indoors and is in a container, you will have to gradually acclimate it to being outside again. Do this as soon as possible, because being indoors is not good for it in the long run. I would set the container in a spot with some gentle morning sun, gradually increasing the amount of sun it receives until it is in the sun all morning. Water to keep the soil slightly moist, not sopping wet and never dried out. Hopefully it will releaf and you can transplant it to the garden in September. In the meantime, fertilize lightly with a water soluble fertilizer such as 10-10-10 at the lower rate on the label. Do not fertilize it after planting, by fall it is too late in the season to be fertilizing. Good luck with your delphinium!
