I've never had one ripen before....

Is this ripe?
How do I know?
From the color?
Or should it be soft?

I also Have 2 oranges that are turning orange,how do I know with them?

I thought I had killed my original grapefruit tree that I've had for 10 years,when I put it out this spring it just started loosing all its leaves,and then just looked dead,I threw it in the compost pile and and a couple of months later noticed little green shoots coming out below the graft.

So I grabbed it and dropped it in the tropical garden and kinda forgot about it.I dug up all the tropicals to go in the house and then when We had a few hard frosts(and snow) I started digging the cannas,well there it was( the old grapefruit) ,still alive and green,I have NO idea what it will be now but I dug it up and its in the GH.

Anyone know what they are grafted to?

Can I graft a peice of my new grapefruit to the old rootstock?
