After my flowers bloom, I let the plants grow (indoors) until it is warm enough to place them outside in partial shade.
I take them out of the pots and shake off the loose soil without injuring the roots and repot in new soil. I let them grow and fertilize them every 2 weeks through the summer.
In September I lay the pots on their sides to let the bulbs dry out. I take them in before frost and store in a cool place.
I bring them in the house in November and start the growing cycle again.
