Yesterday, we dug up our iris and divided them, resulting in over 80 tubers. Available on the curb at 6020 Wellesley Ave, uphill side from Highland, 3rd house on right. Bring a bag and perhaps take a limit of 10? Plant fairly soon: 1. I think it is ok to use scissors and trim the roots to about 5 inches. Otherwise it is difficult to get the many long roots into the hole you dig. 2. Dig a hole deep enough to bury the roots, see #4. 3. If you have some bulb fertilizer like "Bulb Tone" put about 1 tsp. in each hole and mix it in. It might help with a deeper flower color (?) 4. Lay the tuber horizontally in the hole, and cover with soil. But leave the top of the tuber just visible above the soil. Space 3-4 inches apart as they will multiply. Water. Lots of instructions are online too, of course.
