We graft over 350,000 plants per year at Delfland, and we were the first to offer grafted tomatoes to gardeners via mail order in 2005.
There has been a lot of hype in the press recently.
Our advice is that grafted plants are worth the extra cost if you grow your tomatoes in the soil in the same place in the greenhouse every year, as this can lead to a build up of soil-borne diseases.
We do not offer grafted chilli pepper plants because the rootstocks are chilli plants too and so unlikely to produce any extra vigour.
The sweet pepper is grafted on a new improved rootstock. Aubergines are grafted onto tomato rootstocks!
