I really feel for you Ryan - but tomorrow is another day.
My pregnant neighbour grew a wonderful row of runner beans and watched the flowers multiply daily, anticipating the crop to follow. She then dozed off in her garden chair, to be awoken by her toddler daughter bringing her a bunch of flowers - pretty red flowers - she has picked every one of the flowers off the beans!
Try to use the situation to educate your sister - take her to the garden centre and let her help you choose the replacements - make her responsible for daily watering and point out every bit of growth that occurs - help her to take pride in the results of her labours - and don't forget those labels to mark what is planted.
Good luck - hope to hear how it all turns out later.
