How to fertilize Wild Calla

Most potting soils come with ample nutrients which plants use to produce new growth.
By the time your plant has depleted the nutrients in its soil it’s likely grown enough to need a larger pot anyway.
To replenish this plant's nutrients, repot your Wild Calla after it doubles in size or once a year—whichever comes first.

Wild Calla is generally considered an easy-to-care-for plant and makes a great choice for beginners!

Toxicity
Wild Calla is not safe to consume. If you, a family member, or a pet has ingested any amount of plant material contact Poison Control, US (800) 222-1222, or your veterinarian. If you have children, cats, or dogs in the home, we suggest keeping this plant out of reach.
Soil
Wild Calla is very sensitive to dry soil, so choose a potting soil that retains moisture. A good soil will still drain well and contain lots of organic matter such as coco coir or sphagnum moss.
Fertilizer
Wild Calla grows very slowly and doesn’t require added fertilizer. Replacing your plant’s potting soil once a year should provide them with more than enough nutrition. Remember, plants get their energy from sunlight, not fertilizer!
Growth Pattern
Wild Calla grows along the ground and sends out shoots which will spread across the soil.
Growing Outdoors
USDA Hardiness Zone
Wild Calla can be grown outdoors in USDA Hardiness Zones 2a-6b. Find your local hardiness zone here.
Propagation
Wild Calla can be propagated by division into new individual plants.
- Check to see if there is more than one plant. In some cases they may still be beneath the soil surface. If you feel confident, you may remove the soil to check for baby plantlets below!
- If there are multiple plants growing, unpot the plant and gently tug the plants apart, being careful not to disturb too many of the roots. They may be connected by large root segments which you may need to break to free the plantlet.
- Pot up the new plant in well-draining soil
- Repot the parent plant back into its original pot
