Charity Plant Sale

I'm growing pots of beans/peppers/courgettes/squash and tomatoes to sell at work, all proceeds to go to charity. But not sure how much to charge per plant? 

I'd appreciate any suggestions, thanks all... 

I'm planning on selling plants too at boot fairs.

I reckon on between 75p to £1 per plant by the time you've bought seed, compost and 3" pot to pot up in. Consider gardeners Delight Toms:

£2.19p divide by 65 seeds = 3.5p seed assuming all germinate, compost 200ml = 5p, 3" pot =5p based on poundland prices plus 5p per seed electric if you get them going in the heated prop = 18.5p per plant from seed to first individual pot. They are circa £1.50 per plant in the shops depending on what you buy so i reckon between 75p and a pound is about right. That should allow a recoup of costs plus 56.5p charity donation per plant at least.....

Had some very positive feedback from colleagues who have grown lovely tomatoes from my little charity plant sale and even gone on to grow more stuff they bought elsewhere 

We raised £150 !!!

Good stuff! I did that a couple of years ago & just asked for a donation rather than a specific price. Also raised a goodly amount. Fab to introduce folk to growing things too. Loads of my friends are giving me ready chilli updates!
