A three days tomato transplant can be re-transplanted with no problem. Here is What I would do, if I was in your place:

When your other container is set and ready, Water the plant in question REAL WELL and give it times to eat and drink.

Prepare a hole in the new location.
With a hand shovel , go around the plant(, a circle of say 8" in diameter, as if you are carving a watermelon half)

Dig it out( with shovel in one hand and the other hand's help) bring it to the new, prepared location, set it up, fill around it, pressing soil/potting medium gently to pack ...

Now water it, to the point of flooding, so that all the air is out ...

That is all there is to it. Once, when I move from one location, from one town to another neighboring town, I dug up my tomato plant which had been planted weeks ago and had lots of fruits. Transported it and transplanted in my new garden. That tomato plant grew a lot of fruits that summer.

I agree with all the transplanting info already posted. The Hillbilly will be the biggest plant so I'd move it out.

As to the conflicting info on the blooms...the reason you see what looks like conflicts is because there is no one right answer. It is basically your choice. I mostly do, many don't. But when the plant is already stressed just from transplanting I sure would remove them to reduce the stress. When you remove them the plant can go back into developing roots and new growth it will need later on rather than expending energy now on trying to make fruit.

Be sure to do some reading over on the Container Gardening forum here since that is what you are doing. Containers have special needs when it comes to watering and feeding them.

You didn't mention what potting mix you used to fill your containers and that is an important part of the process.

PS: and welcome to growing tomatoes!

Thanks for the replies!

I'm going to finish planting my other veggies and then address the overcrowded tomatoes. Luckily, the Hillbilly doesn't have any flowers yet anyway, so I don't have to make that decision.

I'm using a homemade mixture ...50% peat moss, 20% Miracle-Gro Organic Potting Mix, 20% vermiculite, 10% perlite. I get confused about that part, too. There are so many different opinions and recipes for potting mixes. I guess I'll find out how this mix works for me.

I certainly have never had the greenest of thumbs, but I am optimistic!

50% peat moss, 20% Miracle-Gro Organic Potting Mix, 20%

That means approx. 70% peat moss since that is what the bagged potting mix is - peat moss. You will have some water issues - depending on where you are located.(you need to include that info in the box provided) - and acidic pH issues to deal with.

I'm going to finish planting my other veggies

Are you going to plant other things in that box too? Make things more crowded? The longer you put transplanting the less likely it will survive the process.

Dave.

I realize that the Miracle-Gro is mostly peat moss. I looked at an endless number of mixes and the most common homemade mix was 70% peat, 20% vermiculite and 10% perlite. Some suggested adding the Miracle-Gro as well for some added nutrients due to the compost in it. Like I mentioned, there were so many opinions I was just getting more and more confused and just decided that I needed to make a decision and hopefully this mix will work for me.

When you say water issues, what do you mean by that ...holding too much water, too little etc.?

No, I'm not adding more plants to that box. I have additional boxes that I'm planting as well.

I guess I didn't know if it was better to add more stress to the already shocked plants by moving them again so soon or if I should let them grow a bit in this container and then transplant again once they appear to be healthy again.

Like I mentioned, there were so many opinions I was just getting more and more confused and just decided that I needed to make a decision and hopefully this mix will work for me.

It can be confusing but for future reference, peat repels water for the most part. It is difficult to get wet and then it dries out quickly and once dried becomes water repellant again. It becomes a cycle of water control issues.

The reason it can work in bagged mixes rather than making your own out of plain peat is the bagged mixes have additives. They come wetting agents already added to eliminate the water repelling and they are already pH balanced by adding lime to the mix.

Better to move while it is already shocked then to let it adjust some and then send it back into shock again. Kinda like folks - we'd rather have all the bad news at one time then get hit with a series of bad surprises. :)

Ah ...that makes sense about the peat moss.

Would you suggest using straight Miracle-Gro mix or do you have another mix you would recommend?

I'm debating just moving them into the ground. There is a spot next to my house that the dogs can't get to that gets plenty of sun. I feel like the tomatoes would probably be happiest there ...provided I do some soil prep.
