Growing Tips
- 1Chrysanthemums thrive in full sunlight, so ensure they receive at least 6 hours of direct sun each day.
- 2Water them consistently, keeping the soil moist but not waterlogged, and use well-draining soil to prevent root rot.
- 3Space the plants about 18 inches apart to allow for good air circulation, which helps prevent diseases and pests.

How to Harvest
- 1Harvest Chrysanthemums when the flowers are fully open and vibrant in color.
- 2Use sharp, clean scissors or pruning shears to cut the stems at an angle just above a leaf node to encourage new growth.
- 3Avoid damaging the plant by not pulling the stems and ensuring not to remove more than one-third of the plant at a time.
Step 5
Saving Seeds
How to Save Seeds
Saving seeds from your Chrysanthemum plant is a simple and rewarding process that any new grower can master! Once the flowers have faded and dried on the plant, gently snip off the seed heads and place them in a paper bag. Shake the bag to release the tiny seeds, then separate them from any leftover plant material. Let the seeds air dry for a few days, and store them in a labeled envelope or small jar in a cool, dry place—your seeds will be ready for planting next season! With just a little care, you’ll be able to grow beautiful Chrysanthemums year after year from your very own saved seeds.
