I'm coming back to this thread to say something about volunteers and some frustrations. I included a picture of a volunteer tomato plant in the first post, I'll get back to that plant in a second.
In my continuing relationship with Coyote tomatoes - trying to direct-sow, they didn't even emerge - next, the seedlings were very late coming up in the greenhouse and nearly overwhelmed by their neighbors in a community container. Several years, Coyote tomatoes had shown up as volunteers in the garden. Very,very early to make fruit, it was fine. I just had to tolerate several plants growing while hoping that one would be a Coyote.
Volunteer tomatoes are often something other than Coyote and, therefore, have little chance of ripening fruit before frost. So, Coyote stands apart!
Here is this year's volunteer with the focus on its fruit:

Pretty bad, eh? It appeared very late in June in the weeds along the neighbors fence. I didn't see it earlier and have no real idea why it's there! The weeds shade it as do some of my very tall sunflowers just across the garden's perimeter path. The plant grew some and set fruit.
Two tiny tomatoes that didn't pass the green stage before disappearing! Two more showed up and they also disappeared! I blamed voles.
The picture shows the 3rd pair. I told DW that maybe these were high enuf that the voles couldn't reach them. They ripened!
I needed them ... My transplanted Coyote in the garden ripened fruit nicely even though it had a fairly difficult start back in the spring greenhouse. Maybe, I shouldn't call it a Coyote. You see, it ain't! It's parent must have crossed with a neighbor - the fruit is the right size and a similar flavor but it's the wrong color. So,
obviously a cross

.
This morning, that pair of authentic Coyote fruit also disappeared!!!! Turned out, DW picked them. Thank Heavens, she didn't eat them! That miserably located volunteer has created too much stress!
Oh that tomato volunteer photobombing the picture of the Perilla? Apparently, a Sungold offspring. I decided that from sampling the fruit. Last that I could pick! The dang voles or tree squirrels must be getting them here in the yard, at home.
Steve,
who has plenty of tomatoes from non-volunteers
