| I have been planting annuals in a flower bed but this year my vincas just died back. If there is a fungus, should I treat the soil before replanting? If not, should I mix cow manure or planting soild in with the current soil? |
| The weather and the health of the stock all figure into how well a plant will grow in the garden. It could be that conditions favoring fungal growth were present, along with some sub-standard vincas. I'd work some organic matter into the bed prior to planting again. Aged manure, compost or other readily available material spread on top of the bed and worked in to a depth of 8-10 inches will loosen the soil, help it drain well and yet hold just the right amount of moisture for your plants. Be sure to space your vincas so they get good air circulation all around while they are small, and try to keep water off the foliage. If you can't do that, at least water during the early part of the day so the foliage has a chance to dry off before nightfall. Hope this helps! |
