Grafted tomato

Now grafting a tomato onto a Brug rootstock might be a really good idea, given how big and fast the Brugs grow from seed!

I might even try that this year with a couple of spare plants.

 

Sal, what is stramonio please?

 

Looks like a Datura to me.

 

You need one of these:

The rootstock I’m using (Arnold F1) are thin straggly looking things both under growlights and on a sunny windowsill. They are worse under the growlights, the leaves are small with strange lumps/bumps, the lower leaves wither up and fall off, that has surprised me as I expected them to be fast growing plants. I hope they are putting all their efforts into producing healthy roots instead of leaf growth. Time will tell.

With my normal tomatoes seedlings I've found the same as you under growlights, some are happier than others. Some have purple colouring underneath the leaves (which normally indicates phosphorus deficiency), and withering leaves. Rosada seems to be the worst whilst Gardener’s Delight seems the happiest under my growlights. I’ve moved most out into bigger pots into my greenhouse last weekend and those are looking much healthier already in natural light even though it’s colder out there.
