Gardening in a small area

I'm not sure how small my front garden is but it is quite small. Unfortunately, it is the only area on my lot that gets lots of sunshine. That makes it the only place to grow vegetables in the summer. At some point before we moved here, someone graveled the entire area and so it it just easily to garden in pots. It does present certain problems, one being that the pots can dry out quite quickly. This summer that could make things difficult because we are going to be away a lot. Next week we go back to Othona for 8 days, in mid-July we are off to the American Association of Teachers of French convention in Liège, and then at the end of July we are back at Othona, this time with Naomi and James (oldest daughter and son-in-law). Luckily, I have someone to check and water but it's never the same as you being there.
(Back to the garden) All seems well at the moment. The tomatoes are covered in flowers, the green beans are climbing and blooming, and flowers appeared on the courgettes (zucchini) today. I may have a pumpkin out there masquerading as a courgettes. We'll have to wait and see. I also have herbs - marjoram, parsley, chives, mint, and rosemary.
At the back of the house, the apple tree seems to be producing a bumper crop, as does the grape vine. Our grapes are never very big but they do ripen and they are lovely to eat. I won't count my crops till they actually present themselves but I must admit that I have been thinking of apple and blackberry pies as I pass the blackberry bushes just up the road. It's wonderful to be able to get such a wonderful crop for nothing, just by wondering the lanes with your container picking what you find in the hedgerows.
