Reusing Compost

Hi,
I've got about a dozen large pots on the balcony. They were used to grow onions, shallots, tomatoes, garlic and chiles. The tomatoes this year were a disaster (bottom rot), but the rest of the crops were divine, so I'm getting ready to plant this year's (or next year's!) garlic.

The question is: can I reuse the same compost, or do I need to put fresh stuff in?

Thanks.

 

You need fresh, all the nutrients have been used by this years crop, success or not.

 

Thank you for the very quick response.

 

Helps to give a liquid feed every couple of weeks during the season if growing in pots too

 

Don't throw the old compost away though. Use it as a mulch or top dressing in your garden.
