Using a sharp garden knife will cause the least amount of damage to the roots, as it will be easier to cut them and there will be less hacking involved. Divide the plant further if you desire smaller plants.
Don’t allow mums to wilt between waterings. If the lower leaves wilt or turn brown you need to water them more. Avoid splashing water onto the foliage as this could promote the growth of bacteria or cause your mum to become diseased.
At each watering use a 20-10-20 or equivalent solution. When the blooming season begins, switch to a 10-20-20 fertilizer or equivalent.
Pick off dead or fading flowers to encourage more blooms. This is known as “deadheading”.
Evergreen branches or similar material are good mulch for mums.
If you have an option to choose between morning or afternoon sun, opt for morning sun.
For in-ground planting, choose an area of the yard that doesn’t accumulate too much water.
