Adonis can be sowed in September - winter cold helping with seed germination - or between March and May. Depending on the species and the sowing period, you will get a flowering from May to September!
Water my adonis
Water regularly in the first weeks. Try to avoid watering on sunny afternoons to minimize the amount of moisture lost to evaporation. If your plant is in a pot, check the top soil in the pot either by looking at it or touching it with your finger. In any case, if it hasn’t rained in a month, water !
