How to Propagate Oleander by Division

Dividing your oleander is one of the easiest and most reliable ways to get new plants that are identical to the parent. If you’ve got a massive shrub that’s outgrowing its space, this is the perfect solution. Here’s a quick guide on how to get it done right.

Different Ways to Propagate Oleander

There are a few different ways to propagate oleander, but division is definitely one of the most successful methods. If you’re feeling adventurous, you could also try:

• Growing new plants from cuttings
• Starting them from seeds

Dividing Large and Mature Oleanders

Division is a fantastic move for older, larger plants. It helps you keep a giant oleander under control while giving you “bonus” plants to pot up or share. Just a heads-up: these guys grow fast! They’ll reach their original size before you know it, so make sure you’re staying on top of regular pruning to keep them looking their best.

The Best Time to Divide

The most convenient time to divide your oleander is while you’re repotting it. Since you’ve already got the plant out of the pot and have shaken off the old soil, you’re halfway there! You can easily split the root ball into several sections and move them into their own individual pots.

Ideally, you’ll want to do this in the spring, right after you bring the plant out of its winter quarters. At this stage, the oleander hasn’t started budding or blooming yet, so it can focus all its energy on establishing strong roots and pushing out fresh new growth.

How to Divide Your Oleander

Ready to get started? Here is the best way to divide your plant:

1. Split the root ball into as many sections as you’d like using a sharp knife or garden shears.
2. Make sure every single section has a healthy amount of roots and shoots. It’s especially important that each new plant has at least one main stem.

1. If you notice any rotten or dead roots that need to be trimmed away, make sure to prune back the top of the plant accordingly. You want to maintain a good balance between the roots and the foliage. This ensures the roots can actually support the stems and flowers with enough water and nutrients to thrive.
