And the plants did pretty well.
The watering solution:
I used plant nanny ceramic spikes with wine and plastic bottles, watered the plants really well and for terrcotta pots made sure the outside of the pots were wet too. I then wrapped all the terracotta pots with black plastic garbage bags with some water at the bottom. I used some of the bags as mulch for the plastic pots as well.
And I came back to find bell peppers and tomatoes as well as chrysanthemums (?).
