Growing veg in containers used last year

[littlemoney]

I have two 10 litre pots used for tomatos last year. Can I add some growmore and reuse the compost. Options of seeds for growing in the pots would be either french beans, peas, carrots, beetroot or potato . If it is possible what would be the best crop to grow? Thanks

Yes, you can. I do it all the time.
Beans, peas or carrots would probably be best. Beetroot are quite hungry, and may need more nutrient than your compost can offer, and you shouldn't grow potatoes in the same compost as tomatoes, as they are closely related and share a lot of pests and diseases.
You might also consider beefing the compost up a bit by mixing in a proportion of garden soil, as well as the growmore.

I also reuse my compost repeatedly, cycling through mainly potatoes/tomatoes, carrots, brassicas and sometimes peas/beans on approximately a 3 year rotation. However it doesn't really matter what you follow your tomatoes with as long as it isn't tomato/potato. As tomatoes are very hungry plants you may need to feed the crop you are growing later as well as adding the growmore (I use bfb but the principle is the same), although I wouldn't add too much feed for carrots.

You can grow peas & carrots in the same pot,I sow the peas spacing about an inch apart,then sow the carrot seed one every two inches,it’s ok if the seed goes on top of a pea it’ll move when the pea comes through. Peas germinate first,carrots take longer & you worry because it seems like a whole month before you see carrot greenery. When the peas are ready to harvest,eat them then you can leave the pea roots & some of the plant to supply a bit of nitrogen to the carrots. You can probably grow carrots between the beans too although bean roots are bigger,if there’s any gaps it’s worth putting a seed in.

You've had some good advice all i'll add is that if it has a lot of roots I sieve mine before adding blood/fish/bone.

I re-use nearly all my compost. When a container is finished with, I empty it out onto a plastic sheet and check very carefully for signs of vine weevil or other nasties. If it's contaminated it gets spread out thinly on the garden where the birds can pick over it; otherwise it goes into an old compost bag till next year.

When I am ready to re-use it, I sieve it to get out lumps, bits of root etc and mix in fish, blood and bone at the same time.

I do try and keep compost used for potatoes / tomatoes separate from the other stuff, but I'm pretty sure I don't always manage it. Doesn't seem to matter too much. I always use fresh compost for seeds and for pricking out into, though.
