Learn How to Can and Preserve | The Home Depot's Garden Club

Preserve the goodness of your garden when you learn how to can tomatoes and the rest of your garden’s produce. When the harvest starts rolling in, be prepared with everything you need to preserve, including jars, bands and water bath canners at The Home Depot’s Garden Center.

There’s no great mystery to canning. It’s simply the process of applying heat to food in a closed space such as a jar. Air is removed from the jar, creating a seal and stopping the natural spoilage process. Follow the proper procedures, and your jars of food will be shelf-stable for up to a year. 

The latest trend in preserving food is the innovation in small batch canning. No more clearing the kitchen counters to mass produce jars of tomatoes. These days, you can make a small batch, three pint jars, of jam or salsa after work, or in a weekend afternoon.

Begin with the freshest produce from your garden, the local farm stand or grocery store. Always choose unblemished fruit for canning. Not sure how much you’ll need for a recipe? Check Ball Canning’s Produce Purchase Guide for guidelines.

In canning, there are two types of processing. The first, water bath canning, is for high-acid foods like jams, jellies, fruits and fruit juices, salsas, tomatoes (with added acid), pickles and relishes, chutneys and vinegars.

Pressure canning is used for low-acid recipes for vegetables, meats and poultry. This process keeps foods fresh and safe to eat by heating the contents under pressure to 240 degrees Fahrenheit and eliminating the risk of foodborne bacteria. Pressure canning is necessary when you mix high-acid foods with low-acid foods.
