If you already have a willow tree or two in your yard, you’re in luck—they are incredibly easy to propagate! While there are a few different ways to grow new trees, some methods are definitely more reliable than others. Here’s the lowdown on how to successfully multiply these beautiful trees.
Choosing the Best Method
Willows can be grown from seeds or cuttings. However, if you’re trying to grow them from seed, you’re going to need a lot of luck. Willow flowers are usually dioecious, meaning a single tree is either male or female. For seeds to be viable, you need both sexes nearby so insects or the wind can do their job. If you only have one tree in your garden, getting viable seeds is pretty tough.
If you happen to have a whole grove of willows, they might even seed themselves. You can sometimes find tiny saplings popping up under the mother tree, which you can then dig up and move. Just keep in mind that if you have different varieties nearby, the “babies” might be hybrids rather than a perfect match for the parent tree.
For the best results, I always recommend using cuttings. It’s straightforward, and even professional nurseries prefer this method. While some people use grafting to create high-stem (standard) trees, it’s a bit more technical and not usually necessary for the home gardener.
How to Take Your Cuttings
The easiest time to get cuttings is when you’re already pruning your willow. While you can take them at various times of the year, try to avoid pruning in the summer so you don’t disturb nesting birds. The sweet spot for gathering cuttings is between October and February. I always suggest taking a few more than you think you’ll need, just to ensure you get some strong survivors!
Here’s what to keep in mind:
- Use a sharp, clean pair of pruning shears.
- Look for fresh, juicy new growth.
- Cut your pieces to at least 8 inches (20 centimeters) long.
Once you have your cuttings, grab some starter pots and fill them with nutrient-rich potting soil. Push the cuttings about halfway into the soil and give them a good drink. Place them in a warm, bright spot and keep the soil consistently moist. Just be careful not to let them sit in soggy, stagnant water—you want to encourage those young roots, not drown them!
Planting Your Willows
If you start your cuttings over the winter, you should see little roots forming by springtime. Once the threat of frost has passed, they’re ready for the great outdoors! Young plants can be a bit sensitive to a hard freeze, so timing is key. Pick the perfect spot in your yard and get your new willow in the ground.
