I don't think you can really look at is as a way to save money - yes you'll save cash if you would actually buy the amount of courgettes your plants will produce but who buys 180 courgettes a season? I would never dream of buying fresh peas Id just grab a packet of frozen - far cheaper.
True i know im bound to end up with Waaay more courgette's than i would normally use, but i do actually use alot of courgette's. normally i would say that i use 1 pkt of 3 courgette once a week thats 156 courgettes a year at a cost of £82 a year. (wow thats sounds bad when you write it down haha
)
Granted the ones i am growing have a limited shelve life fresh but i plan to make them into the sauce i normally use them in a freeze on bulk so im certainly hoping that once they are in full production mode i'll be able to make enough pasta sauce for the entire year and enough courgette for stir fry etc (other foods i use fresh courgette) for the summer months, not to mention a whole host of other foods i don't normally make regually because of the price of courgettes (marrow chuckney, courgette tea bread etc)
for what cost?? .... erm seeds where £1.50, soil is free, alittle tom feed so maybe £2 worth in total over the season. 1 bag of compost that used to start the seedlinds off in £1 (asda smart price), a couple of pots so maybe another £1. thats pretty much it really.
total cost of courgettes = £5 if i get more than i can eat it really doens't matter, because £5 is still alot better than my usual annual cougette bill of £82, infact all the better because then i can feed friends and family out of my food bill .. yay.
I could go on and on really ...... i probabally use 1 bag of frozen green beans a week, 52 weeks = £52 a year. this year i've replaced those with french dwarf, french climbing and runner beans.. cost of seeds about £3, feed and neting canes etc pobabally takes it upto about £5 total.
Granted we could start costing up my petrol time etc ... but i till thats going alittle ott, infact i guess i should factor in the cost of the new freezer i bought just to keep these things in to store for winter
but really i think i've done pretty well out of my inital £50 investment. i've recorded £15 savings so far and my foods been cropping for less than a month and most of it is no-where near ready.
True enough its not always like for like comparisons but as long as my family eat i concider it a saving on something i would have bought.
