April · May · What to Plant in July · Seed Catalog. A planting calendar is a simple guide that indicates when is the optimal time to plant any type of vegetable, flower or plant. August August is an ideal time to plant seeds for a second gardening season that can be just as productive as major early spring plantings. Start with the seed indoors and transplant outdoors when it's cold, or buy transplants at your local garden center.
To prepare for the seed start, go to the stores and buy enough suitable growing mix, seed trays, and peat pots (or any other method you plan to use). To keep the information correct, write down your ideal planting day for each seed on a sticky note, attach it to the individual package, and arrange the seeds in chronological order in a card file. Subtract C (total number of days from seed to harvest) from D (first frost date) %3D the last date you should plant the seeds. Two of the most important aspects of gardening are knowing when to plant and what to plant in your vegetable or flower garden.
