When to pick Aunt Ruby's green tomato?

I planted an Aunt Ruby's German Green tomato for the first time this year. I have one that has started turning orangey-yellow on the bottom and sides.

When are they ready to pick?

I don't know the answer, but I also need to find out!

. I have one that has started turning orangey-yellow on the bottom and sides.

i think yours is ready. here is what i found doing a search....
"Aunt Ruby was an actual person, Ruby Arnold (no relation). She lived in Tennessee and died in 1997 at the age of 82 after passing on her wonderful tomato (and several other good tomatoes, including, some claim, the German Stripe ). We should all have such a legacy.
Her German green tomatoes are green when ripe with a pinkish red blush on the bottom. They are large—sometimes over a pound. They come by their heirloom status honestly. They are fragile—even slight squeezes and bumps damage them. They have strange shapes. They will often go rotten in the field. They also have an intense tomato flavor with an irresistible tartness. The first time you eat one you can’t believe you’ve got a green tomato."

here is where i found it- it's a ways down the page and kind of lengthy so i jsut pulled out that part

hope this helps. C

thanks!

no problem, i was curious about them when i saw the question and wanted to check them out and found the answer along the way. they sound so yummy, think i will have to try some out next year.

I went ahead and picked mine yesterday so I could include some slices in a tomato caprese I was making - it was wonderful! I think I picked it at just the right time - after I posted my question I let it ripen another couple of days, but it was showing a light bruise where I had squeezed it to make sure it wasn't going too soft and I was afraid to leave it any longer.

Funny thing, though, the bruise did not show up inside, it only made a slightly dark spot on the outside of the peel.

It had a fairly tart, intensely tomatoey flavor. It went really well with the Big Boy and yellow tomatoes in the caprese. The interior was mostly a darkish green with some red showing.

My problem is, the rest of the huge flowers are drying up and dropping off. Not another flower has set fruit. Is this normal? Or is it just due to our high temps and humidity? Other tomatoes are setting fruit in spite of the drought and high temps, but I'm thinking this one may be picky and a bit fragile.

Also, does anyone know if this one is determinate or indeterminate? I was told it is indeterminate, but it's growing almost like a sunflower, with just one large stem and a few short branches growing from it that put out flowers which die. It seems to have grown to about two feet tall and stopped growing. I'm wondering if I did the wrong thing by pinching suckers. Tomatoes next to it are growing to the top of the trellis.

there was quite a bit more info where i found the other you might find the info your needing at the above link.
