Gardening

It's the second week in May and I still have not planted my tomato plant. Why? It's too cold.
The thought of planting my Sweet Williams and San Marzano when the weather isn't just right seems cruel. But sitting on a sunny window sill isn't a good thing either.
So, out on the balcony they go. I hope they don't freeze.
I am also planting herbs. But of course, they will do just fine on the window sill.
I am interested in finding out how others do with gardening in places other than a backyard.
If anyone has tips to share on patio and balcony gardens, feel free to let the readers know about them.
