Last year I lost all my tomatoes to what I believe was "late blight"
Before I plant this year could someone tell me
1. should I plant in a different garden area?
2. should I put dormant spray on the garden first?
3. can I use the same tomato stakes or should they be replaced?
Do you have any other information that I need to prevent a recurrence ( I only got about two tomatoes last year off of 6 plants)
