Growing Chrysanthemums from Seed
A school project
We want to raise mums from seed for sale in the fall septemberish. We really would like to have full plants in a variety of colors. Our up front money is limited but we have a ton of hands and time. I saw your brief comments on the germination of the mums...
Chrysanthemum seeds are widely available, and are easily germinated as long as they are kept at a constant temperature of 70 to 75 degrees F. A propagating mat under your flats or heating cables buried beneath the seed bed are the best way to ensure that the seeds receive this bottom heat.|
Unfortunately the mats and cables may seem a bit pricey, but keep in mind that they will last several years, and the benefits make them a worthwhile investment. They can also be used to cut the rooting time of cuttings in half.
The seeds should be sown in flats of sterile rooting medium on or before April 1st. Chrysanthemum seeds are extremely small (45,000 seeds per ounce), so use care to ensure that they are evenly distributed.
In about 6 weeks, when the seedlings are at the 4-6 leaf stage, they are separated and transplanted into 2 inch peat pots.
Seedlings should be only handled by the leaves, and a dibble stick, because any damage to the seedling's stem will be fatal, whereas the plant will always grow new leaves. You can make dibble sticks by cutting a small V notch in the end of a popsicle stick.
