propagate | Seeds of Design

I’m propagating this week. A bit behind schedule but then so is the season. Earlier in the year, whilst giving the boxwood and myrtle topiaries a trim, I started some cuttings which have taken root and seem to be doing well. So my focus now is on doing the same with scented geraniums, rosemary and bay. I’ve had good success with them over the years – great returns for minimal effort. A piece of stem bearing a couple of leaves and cut just above a leaf node inserted into moist potting soil is all that’s required. Monitor the pot and you know roots have been set when you see new growth. While it is not absolutely necessary, just to be on the safe side, I dip the cut end in rooting hormone powder before putting it in the soil.

This year, I fell in love with Dichondra Silver ponysfoot. It seems just as easy to propagate – Dig out some pieces of stem with roots attached and replant in potting soil. Keep moist and when it shows new growth, it can be relocated wherever desired. And I do desire greatly!

Other propagation to do is by division. Some of the heirloom irises are on top of the list. They were given to me by a friend when I first started on my present garden many moons ago. Gifts from other gardeners are always so precious. There are ferns, heuchera. Echinacea and asters that also need to be divided and replanted.

Meanwhile, the ornamental raspberry, native anemone and snakeroot need to be ruthlessly thinned out. They are aggressive so I’m not sure if I should give any away or simply toss the lot onto the compost heap. The pink turtleheads have self-seeded happily so some of those young plants will be pulled out and potted to give away.

The cardinal vines and plumbago were such a joy this year that I’m looking io generate more. Should I simply cut the plants back, dig up, split up and pot up? Can cuttings be rooted? Or is starting from seeds the best? Something to learn!

Friends have already stopped by and helped themselves to various seeds straight from the plants. What remains are for the birds. I’m not saving any seeds this year as I’m relying on self-seeded surprises.

Propagation. It’s a good thing.
