It's probably not a good idea to plant iresene until after the last frost because they are not cold tolerant.

The earliest that you can plant iresene in Kent is April. However, you really should wait until May if you don't want to take any chances.

The last month that you can plant iresene and expect a good harvest is probably August. You probably don't want to wait any later than that or else your iresene may not have a chance to really do well. Starting your iresene indoors is a great way to get them started a few weeks earlier.
