Tomato plants potting

I have the plug plants of tomato and I think they are quite big. There are 5 plug plants ( two of one cariety and 3 of other). Can I just transfer them to big pots and can I plant 2 in same pot or one plug plant for each pot ( photos attached).

 

I usually put in final pots when they show flower buds.
I'd stick to just one per pot but obviously it depends on the size of the pot.

They look like good plants.

 

I'd always only pot 1 tomato in a pot, myself.

 

I would repot each plant individually into separate pots and wait for them to develop new top growth before potting them on into their final big pots. Growing more than one tomato plant per pot doesn't work. I have tried it. They are hungry plants and can grow big, 3-4 ft+ tall. I usually put my plants into their final pots when they are about 12 ins. tall, remove the lower 1 or 2 pairs of leaves and plant them deep in their big pots, covering the lower 2 joints with compost as they will form roots along the stems.

 

Thanks a lot. Should I grow them in growing bag or in pots?

 

I personally think Grow Bags are a waste of money. I have tried them and found the compost in them very coarse, if used on their sides as recommended there is not enough depth of growing medium for tomato roots, they need support in the way of 3 canes as well. I ended up using the bags stood on end lengthways which only took 1 plant.
I now use the largest pots I can fit into my greenhouse, 4 pots down each side. By the end of the season the pots are solid with roots from top to bottom. Compost can be almost anything, the essential is to feed the tomatoes every week once the flowers appear. They are very hungry and produce a big crop of fruit and a lot of foliage on comparatively small plants. It is better to feed a weak solution often than occasional strong doses. For a long time I grew my tomatoes in old compost sacks turned inside out and stood in washing up bowls as drip trays. I rolled the tops of the sacks down to about half way to make a rim or handle and punched holes in the bottoms for drainage. Cheap but effective. Easily replaced. Beggars cannot be choosers.
I cannot grow tomatoes outside as Blight is endemic down here so only grow them in a 6x8ft greenhouse, no heating, shaded with old lace curtains or similar. Door and window open day and night.
Except I have to rethink as there is a new resident cat which likes to poo inside my greenhouse, I have a metal grid which I am hoping I can use across the door.
Heath Robinson effort.

 

@Goldenlily26 if you put sticks horizontally across the tops of the pots, it should deter them. The metal grid in the door way will need to be very tall!

 

Caroline,9 this wretched cat just poos on the ground, on the weed matting.
The grid I found here when I moved. It has a frame and feet at each end, it is about 8ft tall when tipped on end and is really heavy so hopefully should work.
