Seedlings need different fertiliser treatment than well - established plants . We ’re about to break it all down .

Mums Started from Seed

If you have started your hardy mum from germ , once the seedling have three or more true leaves , it ’s sentence to act . At this stage you may use well - molder compost or an all - determination , mild fertilizer .

If you ’re using compost , patter a half - inch deep level extending all the way around the circumference of the stem and coming out about six column inch .

Do n’t heap the compost so that it ’s touching the root , however . There should be about an column inch of infinite between the bow and the compost .

Mums Planted in the Fall

Container Mums

As a general rule , plants produce in containers are go away to need more frequent feeding than those plant in the ground .

That ’s because the nutrients percolate out of the soil more quickly each time you irrigate . The grunge does n’t pick up any extra nutrient unless you add them .

To feed container flowers , give them a balanced , soft fluid fertilizer like AgroThrive described above as the buds are spring and every four weeks thereafter . discontinue feeding four weeks before the first omen frost date .
