Marigolds come in three sizes:\u00a018-36 inch tall &#8220;African&#8221; marigolds, 12-18 inch\u00a0medians and 8 -12 inch \u201cFrench\u201d border types and in two color choices- orange and yellow. Begin planting in April or May after frost danger has passed. Figure in a six week period for establishment and marigolds\u00a0possess exceptional\u00a0drought and heat tolerance over the summer months.<\/p>\n<p>Botrytis, also called &#8220;gray mold&#8221;, is a serious fungus disease.\u00a0 Flower petals turn brown and are often covered with gray, fuzzy masses. Brown target-like spots may also appear on the foliage.<\/p>\n<p>Botrytis is most troublesome during periods of extended cloudy, humid, and wet weather conditions. Flowers\u00a0may capture and hold water from rainfall and irrigation. Irrigation should be scheduled in the early morning hours. You should select marigold cultivars with flowers\u00a0that shed\u00a0and\u00a0do not\u00a0retain water droplets.<\/p>\n<p>Sanitation or removing old (spent) and diseases flowers is key to reducing the spread of botrytis through the garden bed. Avoid wetting the flowers when watering and adequately space plants to promote good air circulation.<\/p>\n<p>An alternative is to apply fungicide sprays as soon as disease symptoms appear. Among the pesticides registered for use are Chipco 26019\u00ae (iprodione),\u00a0Daconil\u00ae (chlorothalonil), and either Cleary\u2019s 3336\u00ae or Domain FL\u00ae (thiophanate-methyl).<\/p>\n<\/div>\n","protected":false},"excerpt":{"rendered":"<p>Botrytis Disease in Marigolds Marigolds (Tagetes spp.) have been\u00a0long time favorite summer annuals in Southern Appalachian gardens (USDA zones 6 and 7).
