Learn how to root a cutting and grow your own rose bush
Just a stick? No, it's the start of a whole new rose bush. Rose propagation takes
patience but it can be very gratifying. (Photos: Debbie Arrington)
From little “sticks,” new roses grow.
Pruning season – January and February in Sacramento – also is prime time for rose propagation. A whole new bush can be produced from a single stem.
Roses have the ability to sprout roots from nodes or bud eyes, the area on a stem where a leaf was attached. Bud breaks – the first growth from those bud eyes – look like little red or pink nubs poking out. Those make the nodes easier to spot.
Growth hormones – signaling the plant to sprout – are now flowing through the plant’s vascular system as it prepares to break dormancy (if it ever was dormant this winter). Those hormones also help cuttings to take root.
Rose propagation from stem cuttings can be hit or miss; a 50% success rate is considered very good. So, make several cuttings of the same rose.
Propagation also takes patience. It will take two to three years (or more) for a cutting to develop into a full bush. But with some roses – particularly heritage plants that are no longer available in commerce – propagation may be the only way to preserve that rose variety and add it to your garden.
Master rosarian Dave Coop, former president of the Sacramento Rose Society, shared his method for rooting rose cuttings:
1. Choose a healthy stem with at least four nodes or bud eyes (two for above ground, two for below). Preferably, look for a stem that has bloomed. Cut off the spent flower and any leaves.
2. Prepare your planting medium. Dave mixes potting mix with extra perlite or peat moss to retain moisture. Mix this with water until damp (but not soggy). Pack soil into a 4-inch pot.
3. With a sharp paring knife, gently scrape the green waxy coating of the stem that will be underneath the soil.
4. Dip the scraped stem into rooting hormone powder, available at nurseries and home improvement centers. Chemical powders are available as well as organic options, such as white willow bark.
5. Use a pencil or similar size stick to poke a hole into the planting soil in pot. Gently put the powder-covered stem end into the soil, covering at least two nodes or bud eyes. Gently press the soil around the stem. Water.

7. Place the pot in the shade, preferably on the north side of the house, and keep it watered and consistently moist. Don’t let the soil dry out! And keep it out of the sun!
8. A gentle tug on the stem will tell you if it has formed roots. The appearance of baby leaves is a good sign. After three to four months, the baby plants can be moved into partial shade where they get a little sun each day. But continue to keep their soil moist. (In summer, they may need daily watering.)
9. Once the stems are rooted, the survivors can be separated into individual 1-gallon pots to continue to form roots and grow. After a year, they can be transplanted into the ground.
Super-simple method: Ruth Coop, Dave’s wife, has success taking cuttings and sticking them right into the ground at the base of the mother plant. (This method works particularly well with potted roses.) That way, she easily remembers what the baby plant will be when it starts to grow – and it gets watered along with the mother bush. Once the baby plant is well rooted and growing strong, she transplants it into a separate pot.

Dig In: Garden Checklist
For week of Nov. 26:
Concentrate on helping your garden stay comfortable during these frosty nights – and clean up all those leaves!
* Irrigate frost-tender plants such as citrus in the late afternoon. That extra soil moisture increases temperatures around the plant a few degrees, just enough to prevent frost damage. The exception are succulents; too much water before frost can cause them to freeze.
* Cover sensitive plants before the sun goes down. Use cloth sheets or frost cloths, not plastic sheeting, to hold in warmth. Make sure to remove covers in the morning.
* Use fall leaves as mulch around shrubs and vegetables. Mulch acts as a blanket and keeps roots warmer.
* Stop dead-heading; let rose hips form on bushes to prompt dormancy.
* Prune non-flowering trees and shrubs.
* Clean and sharpen garden tools before storing for the winter.
* Brighten the holidays with winter bloomers such as poinsettias, amaryllis, calendulas, Iceland poppies, pansies and primroses.
* Keep poinsettias in a sunny, warm location – and definitely indoors overnight. Water thoroughly. After the holidays, feed your plants monthly so they’ll bloom again next December.
* Rake and remove dead leaves and stems from dormant perennials.
* Plant spring bulbs. Don’t forget the tulips chilling in the refrigerator. Daffodils can be planted without pre-chilling.
* This is also a good time to seed wildflowers and plant such spring bloomers as sweet peas, sweet alyssum and bachelor buttons.
* Plant trees and shrubs. They’ll benefit from fall and winter rains while establishing their roots.
* Set out cool-weather annuals such as pansies and snapdragons.
* Lettuce, cabbage and broccoli also can be planted now.
* Plant garlic and onions.
* Bare-root season begins now. Plant bare-root berries, kiwifruit, grapes, artichokes, horseradish and rhubarb.
