Create your own garden from scratch with seeds, rather than plants. When opening a garden, the most green method of beginning is from seed. The planters used to hold nursery plants are generally not made from eco-friendly materials, and thus get thrown into landfills. Starting from seeds, or buying from one of the few nurseries that use biodegradable planters, prevents this.
Create a planting calendar for your garden. This calendar allows you to plan ahead for each planting season. This will allow you to prepare ahead of time, letting you know what you need to buy and when. Use a paper calendar, or create a custom calendar online.
When you plan your garden, pick the vegetables your family uses the most and plant those. By doing this, you will be able to use the gardening space to your best advantage, and you will also save money on food bills. There is no point in growing something that your family will not eat, especially if you are limited on space. It just requires doing research, working a lot outside, and having a lot of patience. This work will ultimately pay off for you once you figure out how to make an item grow. All plants need an adequate supply of carbon dioxide in order to thrive. A high level of CO2 provides an optimum environment for growth. A greenhouse has the best levels available. For the best growing conditions you should keep the CO2 levels high.
