Q.Allium Leaf Miner
My leeks have been hit with this and I have lost my entire crop(about 70 in total!)
I have removed the crop and disposed of them at my local tip.
Will I be able to plant another type of crop (non allium) on the ground where the leeks were next year?

You can, but I would recommend treating the soil first. Make sure to apply dolomitic lime, and wettable sulfur to the soil to rid of any fungal growth as well. To get rid of the pest, boil some hot peppers, and a little rosemary oil. If you have garlic handy, then put this in as well. After boiling for 10 or 15 minutes, let it cool, and apply this to the soil. This will get rid of insect pests. After this wait a week, and your soil will be ready to plant anything in.
