Here in New York, now is the time to gather the Rose of Sharon seeds that are all over the trees. I gather a load of then and sprinkle them into Pio's enclosure. In a matter of a week, because of the warm humid environment the start to sprout up. Pio and Izzy love them. If they miss some, the little saplings are allowed to grow bigger. Every now and then I sprinkle a few more. I have enough seeds to last all winter if I do it sparingly.
