|I took some of my plant leaves in to the master gardeners here where I live. They diagnosed my plants with having an early blight. I was told to treat them with a copper fungicide spray so I did that once. I also removed all of the bad leaves and put down wood chips. The leaves are starting to turn bad again though even though I sprayed. Do you have any further recommendations? Thank you! Tammi

|You were right to spray your plants with fungicide and to remove the affected leaves but you need to repeat the sprays every 7-14 days. The fungicide will help protect newly developing leaves from the disease but only if they are sprayed as they are emerging and opening fully. Be sure to apply the fungicide every 7-14 days (the timing of applications should be on the label so read it thoroughly and follow the directions). Hope you can stop that dreaded disease!
