Not if you are going to grow either potatoes or tomatoes on that bit of soil. If your plants were clean with no sign of virus or blight then I cannot see any reason why not, we do.

Hi Owdboggy...I have just read the question...last year my tomatoes had blight and I distroyed the plants and put them in the waste bin.....what can I plant there this year?.

Good question Rogi my tomato plants also got blight, i was going to plant my tomatoes in the same spot but after reading this i'm not sure now!

Tomatoes are like potatoes and should not be grown in the same soil two years running - because of the danger of blight and virus. There is no problem with growing another vegetable in that soil, such as cabbages say, though.
In our case the tomatoes are grown in pots with completely new compost and root vegetables will be sown where the potatoes were.

Thanks bulbaholic, i'll plant something else there instead this year probably peas and might give pots a go for the tomatoes.

Agree with Bh here.
We grow in the polytunnel as outdoor tomatoes just do not grow here. We use bottomless plant pots (1 litre size) with fresh Multipurpose compost in the pots. These are then placed on the soil. We find that this way we get better growth this way. Watering and feeding is done into the pot.
In the Glasshouse we use the same system, except that the pots are placed in Growing bags as the floor in there is concrete. This gives the plants a much greater depth of growing medium than planting straight in the bags.

Hello ... I also plant my tomatoes in pots, and if there is any sign of disease, the soil is taken to the tip! Otherwise I mix it into my compost. Blight resistant strains are reducing this somewhat, but Ferline tomatoes are still the best for flavour and crop!!! I also, as you all do, rotate my potatoe crop ... just to be sure.

Cheers. good answers there ;-))
