old and used compost

[ken the chef]

I have a lot of once used peat free general compost that was used last year to grow potatoes in containers, and a tomato grow bag that I grew two pepper plants in.
My question is:
a.Is there another crop that I can plant in the old peat free compost used for the potatoes?
b.What else could I grow in the tomato compost?
I do have some very good horse manure [two years old] that I could enrich either compost.
I do have three raised beds 9 feet by 3.5 feet that I could spread it over.
The potato crop was not very good. I am not sure if it was down to the peat free element of the compost or that it began to compost a second time while growing the potatoes
Any suggestions will be helpful.

Carrots ? Either in a tub, or - if you have heavy clay like me - dig a narrow trench, fill with old compost, then sow carrots on top. They don't need huge amounts of nitrogen, and come out nice and clean.

What about cut and come again salads? There are so many varieties and mixtures for sale now and they would do well in "second hand" compost, perhaps slightly enriched with old manure.

Dear Ken,
cucumbers? add some of the fym and they will be great. Don't bother trying to grow aubergines or peppers in the spent compost as they are also members of the potato family. With some of the fym mixed in try celeriac as they will need to be potted on a couple of times before planting out.
Fact is with some form of nutrition you will be able to re-use the compost almost indefintley as long as you rotate the crops you grow on it.
When I grow toms, cukes,peppers and aubs I use well rotted compost straight from the bin in the garden. I add an appropriate base fertilizer and then liquid feed as normal trhough the season.
