Annual Garden Calendar

By Jillian Kring 12.14.22

Plan out a year of seasonal gardening by creating a personalized gardening calendar that tells you when to begin germinating, planting, and harvesting your plants. Gardening calendars are a useful tool for the avid gardener. It can get confusing when you have multiple crops to keep track of with varying germinating, planting, and harvesting times. Luckily, drawing up a gardening calendar can give you a general heads-up on when to start germinating and planting seedlings, as well as when to harvest.

Know Your Plants and Agricultural Zone

Choosing your plants and planning your garden is an essential first step before you begin the growing season. Once you have selected your plants, it is important to read the care instructions for your chosen plants based on your agricultural zone. You can find your agricultural zone here. Texas has five agricultural zones (zones 6-10). Because of this, some regions of Texas have two growing seasons, and some are simply so hot in the summer months that very few plants can survive the heat. Knowing your zone will give you an idea of when your first and last freezes are and the window for growing. Calendars are always zone specific, so it is crucial to know your zone.

Germinating, Planting, and Harvesting

Once you have chosen your plants and identified your agricultural zone, you must discover proper germination (if starting from seeds), planting, and harvest times for each plant within your zone. Many useful online tools like this one allow you to enter your agricultural zone and the plants you have chosen for your garden. It then provides you with a calendar for each plant’s germination, planting, and harvesting times. You may have specific plants not listed on this site that may require some further research, but this site provides a list of popular garden plants. Once you have the information, you can make your own personalized planting calendar.

Gardening Basics

Keep in mind that these timetables are very general guidelines and are helpful for planning and garden awareness. There are a great many factors like rainfall, weather patterns, soil health, the amount of sunlight a plant receives, etc., that will determine when a plant is ready for harvest. The indicators that a plant is ready for harvest vary depending on the plant, but you can find a list of some helpful plant-specific tips here.

Create Your Gardening Calendar

Once you have all your information, you are now ready to make your own gardening calendar. Some gardeners find it handy to keep their calendars text based in more of a spreadsheet style, while others enjoy creating a more artistic rendition of their gardening calendar. Whatever your style, this tool will keep you stay on track with your gardening goals this growing season. Below are several examples of how growth schedules vary massively throughout Texas. Here, we have selected daisies, pansies, grapes, watermelon, basil, scallion, bell pepper, and pumpkin for our garden and demonstrated what a gardening calendar would look like in each Texan agricultural zone. Please note: The accuracy of your own calendar will depend on your location, or ZIP code, within Texas’ agricultural zones. Have a wonderful gardening year!
