Are you looking at growing heirloom mums next year? This was my first year trying these and I had some successful beautiful blooms. I just followed these steps!
After you receive your Chrysanthemum plugs you will need to remove them from their shipping packages immediately and place in a shallow bowl of water. Replant each cutting into a 4-in pot. After a few weeks you will need to transfer to a 6-in pot and then a 10-in pot. Sprinkle Osmocote in your potting soil (moisture control is not recommended for potting soil) before each transplant. You will need to pinch plants back to only six leaves per stem. Each leaf will grow a new stem. For disbud mums you will only want to let three of those stems grow to full height. Consider spraying your mums for insects, treat diseases and controlling mites.
In August you will need to make sure you have the appropriate number of stems grown in your 10-in pots. Three per pot for disbuds is recommended. Each stem will need to be staked and tied closely to the stake. Continually remove new growths on each leaf node. You do not want more stems growing from those leaf nodes. Keep spraying for insects, diseases and mites.
You will begin to see buds forming on your stems. When trying to grow a disbud, you only want one bud per stem (three per plant). Sprays can have more stems and buds. Keep spraying for insects, diseases and mites.
Enjoy your beautiful show chrysanthemums!
