Hi

How can you stop mildew from forming on tomatoe plants i lost an awfull lot of them because of the bad summer we had this year.

Thanks

Join the club I have also lost a lot of tomatos. The best way to prevent mildew is to have very good venterlation and do not over water your plants. With us having a warm wet summer it has been very humid so the air has been constantly damp which is great for molds like mildew to grow.

The simple answer is to make sure there is plenty of ventilation and hope you do not have a wet warm summer.
