greenhouse soil - how to improve it

[SADIE39]

hi im in my second year of growing toms, peppers, spring onions, pak choi, cue's etc in my greenhouses, i have tall raised beds in them, i would like to know if i can use the multi purpose compost that i had in these raised beds from last year ?, the multi purpose cost a small fortune last year so i wondered can i just add a fertilizer to the beds to put the goodness back in ?

also i have moss growing on the surface in one greenhouse, shall i just skim the moss off ?

also last year i found the multi purpose compost beds dried out very quickly last year.

a big thankyou in advance.

I am going to use a mixture of soil and garden compost and next year a bit of general purpose fretilizer.

If the beds are to be permanent planters I think it's a better option to introduce some soil into them, it stops them drying out as quickly and seems to stabilise the beds.
Theoretically you shouldn't use the compost again for the same crops, but IMO, if you add a little soil and some fertiliser you should be ok. I don't change the border soil/compost in my greenhouse every year and haven't had any problems

brilliant , thats great infomation, thankyou

I save and reuse MPC many times otherwise it would cost a small fortune. Like the others have said if you add top soil it will help with the drying out problem.

Otherwise add some general fertiliser growmore/blood, fish and bone. Then feed your plants as you would normally do.

There is a product available from garden suppliers, plastic sheeting, black on one side and white on the other. I've used it with great effect under my tomatoes, the white reflects back the sunlight onto the leaves and being plastic reduces water loss. Cheers, Tony.

If you can get it seaweed is supposed to be great for soil health. Not especially high in nutrients but helps unlock anything already in the soil and also has 'magic stuff ' that greatly strengthens general plant health.
