fungus - Knowledgebase Question

Ashby, MA (Zone 5B)
Question by kb1kef

Last year I planted my veggies too close together and the garden developed fungus and all but ruined my garden. Will I have a problem with that this year even though I have completely removed all the old plant life/growth. Will the fungus be still in the soil from last year and can you tell me what to do to the soil to straighten it out. Should I use a lawn anti fungal thing??

Now that you know that overcrowding, dry soil and hot, humid air can encourage powdery mildew you can help avoid the problem in this year's garden by spacing plants far enough apart so there's good air circulation. It's also important that your veggie garden receive at least 8 hours of direct sunshine each day. You don't have to treat the soil, but it will help to keep fungal spores from splashing up from the ground to your plants if you place a 2-3" layer of mulch over the garden after planting your veggies. Cover all the bare soil and not only will you keep fungal spores from splashing up onto your plants, mulching will also help suppress weeds, slow evaporation and moderate soil temperatures. Following the above guidelines should make your veggies quite productive this year. Enjoy!
