It has been interesting to apply age old descriptions of when and how to start your veggies over the last few years. These days it seems better to improve your soil and mulching capabilities so that you can start plants early and grow later.
The great news is this is incredibly easy! Additions of organic mulch, usually available for free in your area ( wood chips, manure, leaves, sawdust-skip the cedar, etc ) are just the ticket. Keep adding this year round, with an addition of a 50:1 Fierce Fish dilution, will create the organic community to support plant health as well.
