So when I received Dobies June Newsletter a few days ago, it all fell into place, it's NOT MY FAULT.
Well it is my fault I suppose, I should have known better than to buy seed from overpriced T&M, whom I've had problems with before.
One thing's for sure, I shall know better next year.

Extract from Dobies Newsletter ......
"It’s all system go at the Dobies of Devon trial grounds this month with a packed programme of trials under way. Many of the trials are of new items that we are thinking of adding to our range but we also carry out trials on well-established existing products to ensure that the seed performs true to type.
An example of this is the much loved Tomato Gardener’s Delight. Last year there were many complaints in the industry (but not here at Dobies) that tomato plants sold as being Gardener’s Delight were not fruiting true to type.
Sadly it seems that some suppliers were selling the cheapest tomato seed and simply calling it Gardener's Delight. Unfortunately, this type of issue is fairly common and is one of the reasons for our constant trialling.
We were able to prove that having trialled 5 different Gardener’s Delight strains ours was and is true to type."
