Late blight? can I treat my soil from last year?

if your garden doesn't have a lot of room to change the location, consider using large pots.... half barrels sized ones... for a few tomatoes... but if you had a large garden with many tomato plants, that's not really helpful, right?....

there is lots of info about blight out there on the state university sites where the blight was so bad, like the NE U.S...... their County Extension offices should have the best help available about now....suggest you contact yours for the best info for your area.....but read here for some real helps, too....

You need to practice crop rotation. This means that you put your garden on a 3 year rotation. One year tomatoes go in one plot, zucchini/squash go in another plot, beans in another. The next spring you move each vegetable to the plot beside the one you planted last year. The reason for this is because once a certain type of plant is grown, the diseases that are common to the plants will be more prevalent in the soil the following year. By rotating you are not giving the diseases a chance to become stronger.

And if you don't want to burn the asparagus, you really don't want to use chemical fungicides or herbicides.

Edit: There is a catalog garden supply that carries mostly organic fertilizers and pesticides. It has wonderful chemical free solutions for most gardening problems. See Link.

You need a fungicide, which will not hurt the asparagus. There are several fungicides on the market that will help control late blight. Late Blight is caused by a pathogen called Phytophthora Infestans that cannot overwinter in the ground without a host (old plants or plant parts). There are many tomato maladies that dictate crop rotation, but late blight is not one of them if proper cleanup procedures are followed each fall.

You were not alone in the blight issues last year! I'm choosing to move my tomatoes to another location this year. Gave me the perfect reason to expand which I have wanted to do and was unable to convince hubby to do so. I'm planting beans, peas, onions, garlic, herbs and salad greens in that location this year. And the beans will add nitrogen back to the soil.

I am afraid of the chemicals and do try to do as much organic as possible. But that's a personal choice = no preaching. Your local garden center should have what you need. Don't go to a place like Home Depot or Lowes; their sales associates have no clue. Find a local nursery or hardware store. I have attached a link below to some organic solutions should you want to explore them.

tomatoes and potatoes are affect by blight, unfortunatly you can not plant in the same spot (planting tomatoes or potatoes) for quite sometime.other veggies are ok. try moving the spot to a place you didnt have plants that had blight. like another spot in the garden.
