Just because summer is over it doesn’t mean it’s time to put away your gloves and trowel. In fact, September is a great time of year to garden and the right time to start sowing seeds for your fall/winter garden. The soil is still warm from the summer sun which encourages newly planted seeds and plants to grow strong and fast. I’m still hopelessly hoping we will get those broccoli seeds in amidst our busy start to the school year because there is nothing like harvesting your own home grown greens.

Essentials to watering a 4- by 5-foot garden bed to a depth of 2 feet (the average depth perennial roots get in clay soil with hose delivering 2-3 gallons per minute) requires a good half hour of steady sprinkling.
