Hi can anyone give a novice gardener some advice please.I have done really well with my sweetpeas. Its the first time i have grown them,they have grown really tall and ive had lots of beautifull fragrant flowers . but now the bottom leaves have gone yellow and the plant dos,nt look very attractive i also have some pods forming.They were grown in a large pot.Is it now time to discard the plant ? The seed packet said they bloom from june to august. i have cut the last of the flowers, there are a few more forming but not many.
