Identify my corn marigold
Harvest chrysanthemums are wild perennials with compound yellow flowers. Thick stems bear oblong leaves. The plant measures on average 60 cm high.
Sow my corn marigold
With these wild chrysanthemums, the easiest way is to sow up between March and May.
- In pots or in the ground, plan that each foot will need 25 cm spacing, so sow a furrow that you will thin out later. Close the furrow to cover the seeds with one centimeter of soil.
- For pot cultivation, sow in a mixture of compost or fibrous compost and sand. Make sure your container is punctured and fitted with a cup, otherwise you risk flooding or premature drying.
- For soil cultivation, find a sunny site in rich and draining soil.
Weed my corn marigold
In perennial species, weeding also means working your flowerbed – don't let anything develop too quickly to the detriment of others.
Water my corn marigold
Chrysanthemums, once installed - and especially properly mulched! - do not have large water requirements. In pot however, water during the summer season but without excess, once a week if it is very dry, rather in the morning and sparing the leaves. The first year however, watch the weather, and bring some water if necessary.
Fertilize my corn marigold
With a respectful approach to soil life, it's always better to fertilize a little in advance with organic material that will decompose; spread out a compost that isn't entirely decomposed, with well decomposed manure at the plant's base, and incorporate over 10 cm with a hoe. This operation is normally carried out in winter so that earthworms and bacteria have time to do their job.
Propagate my corn marigold
You've already sown once, so you know how to multiply your chrysanthemums: get ripe seeds in September, keep them dry and out of the way until the next spring, then sow!
Mulch my corn marigold
Mulch if possible the chrysanthemums, even in pots!
This will prevent you from watering and weeding in summer and it will protect the roots from cold in winter. Dead leaves and grass clippings will do the trick!
