If like me, you will have potting compost left from last year. then it is tempting to use this now for germinating spring planted seeds.
It will not have the same nutrient content as compost sold specifically for seedlings, and what it does have may to some extent go stale (debatable!).
So what about doctoring the former with some homemade nutrient additives to suit seedlings.
I have decided to try adding a couple of drops of household ammonia to water used to moisten the compost (ie extreme dilute): the ready available nitrogen should meet the greatest need.
And to stir in a small amount of very fine spent coffee grounds( to add P & K).
Using the water which has been used to boil my veg for dinner should supply small quantities of other requisites.
