Dividing Arum Lilies: Sharing the Beauty (and Multiplying Your Plants!)

Arum lilies – or calla lilies, if you prefer (Zantedeschia spp.) – are just stunning, aren’t they? Those elegant, often pure white, blooms and the lush green leaves… they bring a touch of class to any garden or even a simple container on a balcony. I’ve always been a huge fan. And guess what? One of the coolest things about these beauties is how easy they are to multiply. We’re talking about dividing them, which lets you expand your collection without spending a dime or breathe new life into a crowded plant.

Getting to Know Your Arum Lily

These plants grow from rhizomes – think of them as chunky, underground stems. They’re like little storage units, packed with all the good stuff the plant needs. From these rhizomes, new shoots and roots pop up, and before you know it, you’ve got a whole clump of lilies. But here’s the thing: sometimes, these clumps get a little too cozy. They become overcrowded, and you might notice fewer flowers or the plant just not looking as vibrant as it used to. That’s your cue to step in and divide them!

Dividing Time: Yes, You Can (and Should!)

So, can you divide arum lilies? Absolutely! In fact, I highly recommend it. It’s like giving your plants a fresh start. The best time to do this is either in early spring, before they really get going for the year, or in late summer/early fall, once they’ve finished flowering. This gives the divided rhizomes a chance to settle in before the next growth spurt or when they go dormant for the winter.

Let’s Get Dividing: A Step-by-Step Guide

Alright, ready to get your hands dirty? Here’s how I tackle dividing my arum lilies:

After the Big Move: Post-Division Care

Okay, you’ve done the hard part! Now, let’s make sure those arum lilies thrive in their new homes:

• Watering is Key: Arum lilies are thirsty plants, especially when they’re actively growing. Don’t let the soil dry out completely – keep it consistently moist.
• Food, Glorious Food: Give your new plants a little boost with a balanced liquid fertilizer every couple of weeks, or use a slow-release organic fertilizer. Something with a ratio around 5-10-10 is usually a good bet.
• Mulch Magic: A layer of organic mulch around the base of the plants helps keep the moisture in and keeps those pesky weeds at bay.
• Winter is Coming (Maybe): If you live in a colder area (zones below 8), you’ll need to dig up the rhizomes in the fall and store them somewhere cool, dry, and frost-free. Then, replant them in the spring when the weather warms up.

Extra Pointers for Arum Lily Success

• Rhizome Shopping: When you’re dividing, pick the firm, healthy rhizomes. Steer clear of anything that feels soft, mushy, or looks like it’s rotting.
• Potting Perfection: A loose, well-draining potting mix is essential. They like slightly acidic soil, so aim for a pH between 6.0 and 6.5.
• Dormancy Drama: Don’t panic if your arum lilies go dormant during dry spells. Just ease up on the watering and let the foliage die back naturally.
• Pest Patrol: Keep an eye out for aphids, especially if you’re growing them indoors. Deal with them quickly before they get out of hand.

Dividing arum lilies is a simple way to get more of these gorgeous plants. Follow these steps, give them a little love, and you’ll be rewarded with a garden full of arum lily elegance for years to come. Happy gardening!
