Yucca gloriosous Spanish dagger
I've got some Spanish daggers which I took as cuttings this year they a really well rooted and about 30cm tall. Should I plant them out the autumn or wait till spring
They are hardy , so unless you have really claggy clay, I would get them in now so that they can continue to grow roots while the soil is still warm.
You don't stop doing new things because you get old, you get old because you stop doing new things.
