Bring your own dirt garden.

An online company that sells kits, an "everything you need but dirt" garden.

Encourage home gardening, fresh eating, saving money, etc.

Raised beds are snap-to-fit, no fancy tools. Starting small enough for a window herb garden, an apartment balcony all the way up to integrated and expandable raised beds for a yard.

Site should have a "plot picker" with recommendations for which plants go where.

• environmental conditions—sunlight and shade, wind and water
• beneficial combinations of plants—ones that like similar growing conditions and can aid one other in other ways
• quick-growing crops like lettuce or radishes can take up the space between slower growing crops like brassicas

The huge selling point will be the ease of gardening, especially for beginners. Each order not only comes with everything but the dirt, but very clear instructions. The below example is horrible but hopefully gets the point accross. A gardener should know exactly where to plant for optimal growing, how to space the seed, how much water to give each plant etc.
