How to fertilize Asclepias Syriaca

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 Asclepias Syriaca after it doubles in size or once a year—whichever comes first.

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

Toxicity
Asclepias Syriaca 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
Asclepias Syriaca 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
Asclepias Syriaca 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!
