An urban garden can occupy a shared, community plot of land, a section of a yard or rooftop, or a container on a fire escape or windowsill. Most edible plants are hungry for sunlight, so look for a south-facing area for your plants.
The only major things one needs to start a garden are soil, a vessel or area to plant in, and seeds. Many gardeners further opt for terra-cotta pots, compost (more about that later), gardening gloves, a watering can, organic fertilizers, and lumber for raised beds.
Zone numbers correspond to when different plants can grow in a region, and seed packets list their zone numbers to help gardeners determine what varietals will do best in specific climates.
If you will grow edible plants, one of the biggest mistakes you can make is growing food you don’t normally like to eat. There’s no reason to grow 15 summer squash plants if you can’t stand ratatouille, or cucumbers if you never eat them.
