Mums are a popular plant in many areas so many stores may not know how to take care of them properly. Do not buy wilted plants or plants with yellowed leaves. To get the healthiest plants you may want to ask the retailer when they will be receiving their next delivery and return on that day. Mums that you intend to keep in containers usually need to be repotted in a slightly larger container with the addition of new soil for best results. Gently break up the roots if the plant is rootbound. Mums are short-day plants, which means they need a long period of darkness to flower. You should use a balanced all-purpose fertilizer. Feed them especially during the vegetative growth period to prevent premature flowering. 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. Treat pythium root and stem rot, fusarium wilt, bacterial leaf spot, botrytis blight, and chrysanthemum white rust with natural fungicides like garlic oil, neem oil or sulfur. Abolish common mum insects like aphids, mites, thrips, and leaf miners with insecticidal soaps or horticultural oils. This ensures you will have domes of brightly-colored blossoms come autumn. Pick off dead or fading flowers to encourage more blooms. This is known as "deadheading".
اختر نباتًا صحيحًا. أعد تأصيص أقحوانك. أبق الأقحوان بعيدًا عن أضواء الشارع أو الأضواء الاصطناعية خلال ساعات الليل. سمد الأقحوان عدة مرات في العام. عالج الفطريات بمبيدات الفطريات. حافظ على نظافة مكان النبات وخلوه من فتات النبات لمنع الآفات والأمراض. اضغط أطراف نباتات الأقحوان اليافعة مع بعضها في أواخر الربيع وبدايات الصيف لجعلها كثيفة ومضغوطة.
