Hi

Last Autumn I bought some Penstemon Plugs. I have overwintered them in the greenhouse, potting them on. They are now quite big and strong. Can I plant them out yet or do I need to wait until after that last frost please?

Thanks
Dawn

When to plant Penstemons

Reply from ALISTAIR OLVER

Hi Dawn,

It is still too earlier to plant Penstemons out. Wait until the end of April, when the frosts have passed; even the more hardier perennials are just beginning to get going.

Hope this helps!

Additional Info on Penstemons

Hi again Dawn

Just thought I would add, I think the variety you have listed is one of the hardier ones, however, always leave the older foliage on through the winter, this helps to protect the base of the plant from frosts. Once you start to see new growth appear at the base in the spring, this is the time to prune away the old foliage just above the new growth. If you can, take some cuttings during late summer as an insurance policy against the mother plant from dying during winter.

Thank you again

Hi

Thanks. On a couple of the plants the old foliage is starting to look a bit rough and I was getting a bit concerned. Some of them already have new shoots at the base so this information is invaluable, thank you.

All the best
Dawn
