One of the most enjoyable things that I do in the garden is taking cuttings. I can’t help myself. If I prune something, I almost always end up making cuttings from the prunings, whether or not (and usually not) I need more plants. It’s irresistible. I’ve always found the propagation of plants to be exciting, a celebration of life that is almost more thrilling than seeing a plant bloom (another act of procreation).
Beginning as a child, I delighted in starting seeds, watching the cotyledons poke out of the soil. Later, I learned about division, ground layering, air layering, root cuttings, hardwood cuttings, semi-hardwood cuttings, and softwood cuttings, leaf cuttings, grafting. I find each of these to be a joy, except grafting, which seems to sacrifice one life for another, and the making of one (the rootstock) the slave of another. There’s not much joy in that.
I still find the emergence of seedlings to be wondrous. It is even more pronounced by the waiting imposed by the necessity of stratification of some seeds. After waiting three months with penstemon seeds in the refrigerator, they sprang to life on the windowsill (only to be eaten by birds when I tried to harden the seedlings off, but that’s another story).
I have recently considered that taking cuttings may have surpassed starting seeds in fun. When I have to prune back a plant that is growing enthusiastically, those lush shoots are just the perfect size and frequently the perfect stage for a cutting. How can I deny them a chance at life? Some plants, of course, are much more amenable to cuttings, although that doesn’t stop me from trying the harder ones. But the easy ones are thoroughly satisfying. The American Horticultural Society book Plant Propagation is one of the most read book on my shelf even if I don’t actually do the propagation.
There are some plants that are particularly fun for me to take cuttings. It’s usually because they root quickly.
Salvia ‘Indigo Spires’ is one that I can’t resist. It roots so fast from a tip cutting that it seems to put down roots almost as soon as the cutting is struck. Once, when I first planted ‘Indigo Spires’ something came along and chewed off the stems at the bottom. By the time I found it, lying in the sun, the leaves were beyond wilted - they were crispy on the edges. Still, I had to try, and I trimmed the dry bottoms, and threw them in a glass of water. Amazingly, the two pieces perked up, despite the dried leaf edges, and I struck them as cuttings. A week or two later, and roots were coming out of the drainage holes. It’s also satisfying to grow since ‘Indigo Spires’ grows into a large plant, 3-4 feet in height and diameter, with 2-foot flowering spikes.
Nepeta ‘Walker’s Low’ (shown above, left) also seems to grow roots faster than you can imagine. Taking a young non-flowering shoot a few inches long, plucking off the lower leaves and throwing it into a pot of dirt is all it takes. A week or two later and new leaves are sprouting and roots are coming out of the drainage holes.
It was surprising to find how easily rosemary roots from 2-inch tip cuttings. It does take a few weeks, and it is best to take cuttings from shoots that seem too young to succeed. Still, they work better than the winter-hardened stems. A little rooting hormone seems helpful, but if I did a comparison study, I bet it wouldn't make a difference.
I tried to grow Ceanothus cuttings for years. I tried heel cuttings, tip cuttings, softwood cuttings, hardwood cuttings, in the spring, summer, fall and even winter but to no avail. A couple of years ago, I was successful with my prized Ceanothus caeruleus, taking spring cuttings and using a liquid rooting hormone. I tried again this spring, and every one of the heel cuttings failed, but the tip cuttings look as if they have succeeded. Lesson learned. There's nothing as satisfying as success.
Dianthus (above, right) is known for its ease of propagation. Some books say to grab a bunch of stems, twist them together, and plant them. Watered and shaded, they will root. This is probably why they are so popular in cottage gardens, which is known for the hand-me-down plants. I find that dianthus takes a few weeks to root, so is less immediately satisfying, but nearly every cutting will root.
Similarly, tip cuttings of the ground-cover Veronica also root easily and reliably, which is exciting since I find the plants to be such a treasure. Similar also is culinary sage, if a young non-flowering shoot is chosen. It’s just as easy to divide sage, though, as it self-layers.
I take cuttings of almost every plant in my garden, just to see what will happen, but other plants are less satisfying for whatever reason. Sedum is too easy, when every bit left in the garden roots and grows. Lavender takes a few months to root and it takes a season or two before the plants seem to build up enough strength. Because of this, I find it’s worth it to buy plants. Euphorbia characias cuttings seem to need to be taken at exactly the right time of the year, when they are easy, but wait too long and I find it is a struggle.
