Gardening Questions And Answers
Fungi, diseases, insect pest infestations and poor environmental conditions can all lead to browning of the foliage and leaves. Fungal problems often arise when the soil or plant is too wet, too often. Leaf spot (caused by Septoria species) and brown rust (Puccinia spp.) both commonly afflict chrysanthemums.
Early bloomers often begin flowering in late July, early fall bloomers show off blooms in September and late fall bloomers start their stunning display of colors in October. Each variety differs, but most mums will continue to bloom for four to eight weeks. There are many ways to extend the flowering of chrysanthemums.
The flowers may wilt and die quite suddenly. Mealybugs and aphids are two that do this, while chrysanthemum thrips attack the buds and flowers. Finally, poor environmental conditions such as overly wet or dry soil weaken the mums, which can lead to the plants becoming more susceptible to fungi, diseases and insects.
Home gardeners can increase the odds of their garden mums surviving the winter by protecting them with mulch in fall. Do not cut back the plants in fall. Simply place several inches of mulch around the mums. Suitable mulching materials include clean, weed-free straw, pine needles, and evergreen branches.
Years ago, chrysanthemums required extensive pinching and trimming in order to grow into a bushy plant loaded with flowers. Modern cultivars can grow into attractive plants without extensive trimming, but taking the time to prune them makes them look even better. Hardiness varies among the many species and cultivars.
We’re talking about Chrysanthemums (mums), or daises. Are these picturesque flowers poisonous to pets? Our sources conclude yes, mums are toxic to pets, particularly dogs, cats and horses. Symptoms of ingesting the flower include vomiting, diarrhea, hyper-salivation, incoordination and skin inflammation.
Mums benefit from extra Mg. While Epsom Salts (MgSO4) is often included in growing media, that dose is often spent after several weeks. Mg deficiency appears as an interveinal chlorosis on the lower leaves. Apply SiMag58 at 2-3 ounces per 100 gallons of solution every other week (or more often if needed).
Aphids of multiple varieties are most commonly found on or near chrysanthemums. They’re small and round — often brown, black, green, or white — and leave behind a sticky substance known as honeydew. Mites, especially spider mites, are even smaller than aphids, making them easy to miss until they’re out of control.
