Table of Contents

Arabis is a beautiful flowering plant that belongs to the mustard family. It's native to Europe, Asia, and North America and is valued for its attractive blooms that range from white to pale pink. Propagating Arabis can be highly rewarding and is an excellent way to add this stunning plant to your garden. In this post, we'll explore the different techniques you can use to propagate Arabis successfully.

The beauty of Arabis

Arabis is an ideal plant for rockeries and garden borders, thanks to its low growth habit and impressive display of flowers. Their blossoms are typically small and come in neatly arranged clusters that create a pleasing effect. They bloom in spring and are up to eight inches tall.

Why propagate Arabis?

Propagating Arabis is an excellent way to increase the number of plants you have available quickly. You can share them with friends or neighbors, fill gaps in your garden, or even grow new specimens for sale. Additionally, propagating Arabis is also a cost-effective way to obtain new plants as buying multiple plants can be expensive.

Arabis Propagation Techniques

Arabis can be propagated by seeds, cuttings, or division. Here are some simple techniques you can use to propagate Arabis successfully:

From Seeds

1. Collect ripe seed pods in late summer and early fall.
2. Allow the seeds to dry completely before storing them in a cool, dry place.
3. Sow the seeds indoors in late winter or early spring.
4. Cover the seeds with a thin layer of soil and water gently.
5. Keep the soil evenly moist until the seedlings appear.
6. Transplant the seedlings into individual pots once they have developed their first set of true leaves.
7. Plant them in your garden once they have grown big enough to handle transplanting.

From Cuttings

1. Choose healthy stems from established plants to use for cuttings.
2. Cut a stem that's 4-6 inches long and remove the bottom set of leaves.
3. Dip the end of the stem in rooting hormone powder.
4. Insert the cutting into a pot filled with a rooting medium.
5. Cover the pot with a plastic bag to create a humid environment.
6. Place it in a bright location, but avoid direct sunlight.
7. Keep the soil evenly moist until the cutting develops roots.
8. Transplant the new plant into a larger pot or directly into the ground once it has matured sufficiently.

From Division

1. Choose an established Arabis plant that's at least two years old.
2. Lift the entire plant out of the ground with a shovel.
3. Gently shake the soil off the roots.
4. Divide the plant into smaller sections using a sharp knife. Each section should have some roots attached.
5. Replant the individual sections in prepared soil.

Arabis Care Tips

Proper care is essential for the health and growth of your Arabis plants. Here are some tips you can use to keep them healthy:

Light and Temperature

Arabis prefers full sun to partial shade. It thrives in well-drained soils and does not tolerate wet feet. Therefore, it's best to water the plant when the top inch of soil is dry.

Soil and Watering

Arabis grows best in soil that drains well. Soil pH should be slightly acidic to neutral, around 6.0 to 7.5. Water regularly but avoid overwatering to prevent root rot.

Fertilizing

Arabis rarely needs fertilization. However, if the plants look weak or pale, you can apply a balanced, slow-release fertilizer as per package instructions to boost growth.

Arabis Planting Advice

Here are some tips on how to plant and care for your Arabis plants:

Best Time to Plant Arabis

The best time to plant Arabis is in the spring when the soil is warm enough for seeds to germinate. For established plants, fall is the ideal season to plant them, allowing time for root establishment through the winter.

Soil Preparation

Prepare the soil by adding organic matter such as compost or well-aged manure. This will improve drainage, fertility, and soil texture.

Planting Arabis

Planting Arabis is easy. Dig a hole in the prepared soil that's deep and wide enough to accommodate the plant's roots. Place the plant in the hole, making sure it's level with the surrounding soil surface. Water the plant generously immediately after planting.

Growing Arabis from Cuttings

Growing Arabis from cuttings is an excellent way to propagate new plants that are genetically identical to the parent. Here are some basic steps:

When to Take the Cutting

Take cuttings of Arabis in the spring or early summer when the plant is actively growing.

Preparing the Stem for Planting

Select a healthy stem that does not have any flowers or buds. Trim away any leaves on the lower half of the stem.

How to Plant the Cutting

Plant the cutting in a pot of well-draining soil. The soil should be moist, but not wet.

Caring for Your New Plants

Place the pot in a bright, warm location such as a sunny window or greenhouse. Keep the soil evenly moist and avoid overwatering. Once roots have developed, transplant the new plant into individual pots or directly into your garden.

Propagating Arabis can be an incredibly rewarding hobby. With the right techniques and care, you can grow healthy plants that will add beauty to any garden.
