Reviving plants after 3 weeks of no care
I live in an apartment and have a lot of plants growing on my balcony. However, I have recently left for a 3 week vacation and the girl that was supposed to water them only did so once. I just arrived back today and they look very brown and dead. I know very little about gardening and have previously only been watering them. Should I just get rid of them or what should I do?
