Propagating weigelas cuttings is a simple and rewarding way to boost the growth of these beautiful plants in your garden. Weigelas, known for their small bearded flowers in various colours, are a popular choice among gardeners because they add a touch of elegance to any landscape. Whether you’re a beginner or an experienced gardener, this guide will provide you with all the necessary information to successfully propagate weigelas from cuttings.
Before you begin the propagation process, it’s important to choose the right timing and location. The optimal time to take cuttings is in early summer when the new growth is emerging. Look for healthy branches that are about 4 to 6 inches long and make sure to take cuttings from disease-free plants. When selecting a location for planting the cuttings, make sure it is well-draining and receives ample light.
Once you’ve carefully selected the cuttings, the next step is to prepare them for planting. Start by making a clean, slanted cut just below a set of leaves. This will create a wound that will encourage new root growth. Remove any leaves or flowers from the lower half of the cutting, leaving only a few on the upper half. This will help prevent water loss and mildew problems.
Now it’s time to plant the weigela cuttings. Fill a small pot with a well-draining potting mix and moisten it slightly. Make a hole in the potting mix and place the cutting in it, making sure the wound is covered and the cutting stands upright. Gently press the potting mix around the cutting to secure it in place. You can plant multiple cuttings in one pot, but make sure they are spaced apart to allow room for growth.
Once the cuttings are planted, provide them with proper care to ensure optimal growth. Place the pot in a warm and bright location, but avoid direct sunlight, as this can cause the cuttings to dry out. Keep the potting mix consistently moist, but not waterlogged. You’ll likely see signs of new growth within a few weeks, indicating that the cuttings have successfully taken root.
To prevent overcrowding, it’s important to prune the weigela cuttings regularly. This will encourage branching and help the plant develop a fuller shape. Pruning should be done after the first year of growth, and you can remove up to one-third of the plant’s height. Be sure to follow proper pruning techniques to avoid damaging the plant.
Overall, propagating weigelas cuttings is a rewarding process that allows you to create new plants with the same characteristics as the parent plant. By following the steps outlined in this guide, you’ll be able to successfully propagate weigelas and enjoy their beautiful flowers year after year.
How to take hardwood cuttings
Taking hardwood cuttings is a long and tricky process, but with the right guide, you can propagate weigelas and grow more plants. Hardwood cuttings are taken in winter when the plant is dormant. This is the best time to take cuttings since the woody stems are more likely to root successfully.
To take hardwood cuttings, follow these steps:
- First, select a healthy, disease-free and pest-free weigela plant as the parent plant.
- Use sharp pruning shears to cut 2-4 long stems from the parent plant. Make sure the stems are strong and healthy.
- Prepare the cuttings by removing any flowers or buds from the stems. Make a clean cut just below a node (a swollen area on the stem).
- If the parent plant is a variegated weigela, it’s best to take cuttings from the variegated stems to ensure that the new plants will also have variegated leaves.
- Using a rooting hormone is optional, but it can increase the chances of root formation. Dip the bottom end of each cutting into the rooting hormone to improve its ability to grow roots.
- Insert the prepared cuttings into a pot filled with a well-draining soil mix. Make sure at least two nodes are below the soil level.
- Water the cuttings thoroughly and place the pot in a location that receives bright, indirect light. Keep the soil moist but not waterlogged.
- Some weigela cultivars, such as ‘Polka’, ‘Rubidor’, and ‘Prince’, can be propagated by seeds. Sowing the seeds in a mini greenhouse or greenhouse-like environment can improve their chances of germination.
- Provide a frost-free environment for the cutting over the winter. This can be achieved by keeping them in a greenhouse or by covering them with a frost blanket.
- The following spring, when new growth emerges, you can carefully transplant the rooted cuttings into larger pots or directly into the garden.
When transplanting, be careful not to damage the fragile roots. Weigelas grow best in full sun to partial shade and prefer well-draining soil. After transplanting, water the new plants regularly and provide them with a balanced fertiliser to promote healthy growth.
Keep an eye out for signs of pests or diseases, such as aphids, ants, or leaf yellowing. If you notice any issues, treat them promptly to prevent loss of the plants.
Overall, with proper care and preparation, taking hardwood cuttings can be a successful way to propagate weigelas and increase your garden’s variety and beauty.
Step 1: The first cuts
When propagating weigelas through cuttings, you will need to take the first cuts from the parent plant. Start by choosing a healthy companion branch that you would like to propagate. Look for a branch that is long and has a good amount of foliage. It is also beneficial if the chosen branch is a variegated cultivar, as it adds visual interest to your garden.
Before making the cuts, make sure you have all the necessary equipment. This includes a sharp, sterilized pruner or scissors, a rooting hormone powder, a clean potting mix, and a planting tray or pot. Additionally, moist soil is needed to keep the cuttings healthy throughout the process.
To begin, make clean cuts just below a set of nodes on the chosen branch. Nodes are small, round spots from where leaves or branches grow. By cutting just below a node, you provide the cuttings with more opportunities to absorb water and nutrients.
After making the cuts, dip the ends of the cuttings into rooting hormone powder. This helps stimulate root growth and increases the chances of successful propagation. Be sure to gently tap off any excess powder before planting the cuttings.
Next, prepare the potting mix by filling the planting tray or pot with a well-draining soil mixture. This helps prevent waterlogging, which can lead to fungal issues. Press the potting mix down lightly to ensure good contact with the cuttings.
Now it’s time to plant the cuttings. Make holes in the potting mix using a pencil or your finger, about 2-4 inches apart. Insert the cut ends of the weigela cuttings into the holes and gently press the soil around them to secure their position.
After planting, give the cuttings a good watering to help settle the soil and ensure that they have enough moisture. However, be careful not to overwater, as this can lead to rotting. Throughout the propagation process, it’s important to consistently water the cuttings to keep the soil consistently moist.
Once the cuttings are planted, it is recommended to place the pot or tray in a warm, well-lit area. A temperature of around 70-75°F (21-24°C) is ideal for encouraging the root development. Additionally, keep the cuttings out of direct sunlight, as this can cause them to dry out.
During the propagation period, which typically takes 4-8 weeks, it is important to regularly check the soil moisture and adjust watering as needed. Be mindful of any signs of plant stress, such as wilting or yellowing leaves, and address them promptly.

Step 2 Right way up
When it comes to propagating weigela cuttings or offshoots, it is important to place them in the correct orientation. If you’ve taken relatively long cuttings and their shape allows it, make sure to stand them right way up. This means that the end that was closest to the base of the mother plant should be placed in the soil, while the top end with the shoot should stand upright.
This is important because the bottom end of the cutting is where the new roots are most likely to develop. If you plant the cutting upside down, it may have difficulty producing roots, resulting in a failed propagation attempt.
Furthermore, placing the cutting right way up also prevents problems when it comes to overwintering. Weigelas, like many other garden plants, have buds that need to be protected during winter. Placing the cutting in the correct orientation ensures that the buds are facing upward, which helps prevent scorch damage from winter sun and allows for better moisture absorption.
If you are propagating variegated weigela cultivars, it is especially important to place the cutting right way up. Variegated plants have a mix of green and white foliage, and if the cutting is planted upside down, the green leaves may grow first, limiting the development of the variegated foliage.
When preparing the cutting for planting, you can use a rooting hormone to increase the chances of successful propagation. This hormone helps stimulate root growth and can be applied to the bottom end of the cutting. However, this step is not necessary and weigelas can be propagated without the use of hormones as well.
- Moisten the potting soil before planting the cutting to provide a good environment for root development.
- Make a deep hole in the soil for the cutting to ensure that the roots have plenty of room to grow.
- Place the cutting in the hole, making sure the bottom end is in contact with the soil.
- Backfill the hole with soil, firming it gently around the cutting to provide support.
Cuttings are best planted in a location where they will receive plenty of light, but not direct sunlight. Weigelas can tolerate some shade, but they will grow best and produce more blooms in a sunny spot.
Providing proper care for the cuttings after planting is also important. Keep the soil consistently moist but not waterlogged, as excessive moisture can lead to root rot. Over time, the cutting will develop roots and begin to grow. It may take several weeks or even months for the cutting to start showing signs of new growth, so be patient and continue to provide the necessary care.
