Gently remove the shrub from its container and loosen any tangled roots.
Place the shrub in the hole and backfill with soil, tamping down gently to remove any air pockets.
Water thoroughly and add a layer of mulch around the base of the shrub to retain moisture and suppress weeds.

Maintenance and Care
Caragana arborescens is a low maintenance plant that is perfect for beginner gardeners.
However, there are a few things to keep in mind to ensure that your Siberian peashrub stays healthy and vibrant.
Watering Requirements
Siberian peashrubs are drought-tolerant plants, but they still require regular watering, especially during the first few years of growth.
Water your plant deeply once a week, making sure that the soil is moist but not waterlogged.
During hot and dry weather, you may need to water more frequently to prevent the soil from drying out completely.
Pruning and Shaping
Pruning and shaping your Siberian peashrub is essential to maintain its shape and promote healthy growth.
Prune your plant in late winter or early spring before new growth appears.
Remove any dead, diseased, or damaged branches, as well as any crossing or rubbing branches.
You can also shape your plant by removing any unwanted shoots or branches.
Fertilizing and Mulching
Siberian peashrubs do not require frequent fertilization, but you can apply a balanced fertilizer in early spring to promote healthy growth.
Mulching your plant with organic matter, such as compost or shredded leaves, can help retain moisture and suppress weeds.
Pest and Disease Management
Siberian peashrubs are generally pest and disease resistant, but they can be susceptible to aphids and spider mites.
If you notice any signs of infestation, such as curled leaves or webbing, you can spray your plant with a neem oil solution or insecticidal soap.
Regularly inspecting your plant and removing any dead or diseased branches can also help prevent pest and disease problems.
By following these simple maintenance and care tips, you can enjoy a healthy and beautiful Siberian peashrub in your garden for years to come.
Propagation Methods
Seed Collection and Sowing
Caragana arborescens can be propagated by seeds.
The best time to collect seeds is in late summer or early fall when the seed pods have turned brown and are dry.
The seeds should be collected and stored in a cool, dry place until they are ready to be sown.
To sow the seeds, prepare a seedbed by loosening the soil and removing any weeds or debris.
The seeds should be sown in shallow furrows and covered with a thin layer of soil.
Water the area gently, but thoroughly, and keep the soil moist until the seedlings emerge.
Cuttings
Caragana arborescens can also be propagated by cuttings. Cuttings should be taken in early summer when the new growth is still soft and flexible.
Select a healthy stem and cut a 4-6 inch section just below a node.
Remove the leaves from the bottom half of the cutting and dip the cut end in rooting hormone.
Prepare a potting mix of equal parts sand and peat moss and fill a small pot with the mixture.
Make a hole in the center of the potting mix and insert the cutting. Firm the soil around the cutting and water well.
Cover the pot with a plastic bag to create a humid environment and place in a bright, but indirect light.
Check the cutting regularly for signs of growth and remove the plastic bag once the cutting has rooted.
Once the cutting has rooted, it can be transplanted into a larger pot or directly into the ground.
