Weigela are popular shrubs that are prized for their vibrant trumpet-like blooms that emerge in late spring to early summer. If you are a fan of color in the garden, weigela plants are a surefire way to add impact to any yard.
Propagating your weigela shrubs is both cost-effective and fun, and by following a few simple steps, you will be able to add even more colorful shrubs to your plot in the coming year with little expense.
So, while you might know how to grow weigela, why not consider taking cuttings? Our expert guide has all the information you need to know, including tips on timing and aftercare.
Growing weigela shrubs
'Weigela are striking and hardy plants,' says Natalie Carmolli, garden expert at Spring Meadow Nursery. 'They can tolerate a wide range of climates and conditions but are very well suited to cold regions, growing well even down to US hardiness zone 4.'
As Natalie says, these are tough and impressive shrubs, and fortunately for us gardeners, they are also excellent plants to take cuttings from. Follow our guide to learn the right approach for weigela cuttings.
When to take weigela cuttings
In terms of timings for weigela cuttings, softwood cuttings can be taken from your shrubs during early summer, usually around June. This is best done when new stems are still young and flexible.
Hardwood cuttings using old, woody stems are usually taken when the temperature drops in late fall or early winter. For the best results, take hardwood weigela cuttings after the arrival of the first frost, which will vary depending on where you live and the local climate.
How to take weigela cuttings
- Using clean, sharp tools, like these Felco pruning snips from Amazon, make your cuts. If you are taking softwood cuttings in early summer, select fleshy, green stems that measure 8 to 10 inches long. For hardwood cuttings in fall or winter, choose woody stems that measure 10 to 12 inches. Make your cuts just below a leaf node.
- For green, softwood cuttings, remove all but two leaves at the top of the stems, whereas for woody, hardwood cuttings, remove any foliage that remains on the stems. Do not worry about stripping any remaining foliage at the time of year, as the hardwood cutting is dormant.
- While rooting hormone is optional, it can help to generate the best results. Simply dip the bottom inch of your cuttings in rooting hormone powder, available from Amazon, before planting them into small pots filled with well-drained potting mix. You want to bury about half the length of each cutting.
- Softwood cuttings taken during the summer can be placed in cold frames or unheated greenhouses. However, for hardwood cuttings in fall or winter, you may want to use a heated propagation mat to increase the chances of success.
- You only need to water hardwood cuttings sparingly, as they will not actively absorb moisture during fall and winter when they are dormant and not growing. In summer, keep your softwood cuttings moist but not waterlogged, monitoring the soil every few days and misting as necessary. From June, as the temperatures soar, you may need to water more frequently.
- Keep softwood cuttings out of direct sunshine during the first month or two, while the cuttings settle and produce roots. Your softwood cuttings should produce roots within six weeks, whereas hardwood cuttings will not show signs of life until the spring.
This rooting hormone powder will improve your chances of success when propagating weigela via cuttings.
Using a propagation heat mat will help to protect your weigela cuttings during the fall and winter months.
This mix is ideal for your weigela cuttings, with added drainage material and nutrients to help your plants thrive.
FAQs
Can I plant Weigela cuttings in a border?
Yes, when your plant has a good root system and has grown several leaves, you can plant it in your yard. 'Weigela are pretty easy to grow,' Natalie says, 'but they do prefer well-draining soil that is slightly acidic to neutral. A pH range between 6.0 and 7.0 is optimal but they are not terribly fussy, just give them plenty of sunshine and good soil structure.'
Can I keep my cutting in a pot?
'Sure, growing weigela in pots can be done,' continues Natalie. 'When planting cuttings into bigger containers, use a good quality, well-draining potting mix and choose a container that is large enough to accommodate at least one season of growth of plant and root mass. Remember also that container-grown shrubs require more frequent watering during the warmer months.'
Always take more cuttings than you think you need, as some will fail, so taking extra cuttings is an insurance policy. You also want to repot your plants into a more nutritious potting mix when they show signs of growth and produce a new set of leaves. Seed and cuttings compost is typically low in nutrition, which is fine when the cuttings are young, but they will not turn into healthy plants if left in this soil for months on end.
