September is a busy time in the Marin County Garden! It’s a great month for continuing to harvest all the goodness of the summer garden, like eggplants, tomatoes, peppers, etc. It is also time to start planting your cool season vegetables, herbs, and flowers. Getting the fall veggies established in the garden before the cooler weather arrives is important for plant health, productivity, and resilience throughout the fall and winter months.
Early in September we like to pull out the summer crops that are looking spent and have become less productive to make space for a few cool season plants. Later this month we will do a clean sweep of the garden removing everything (even if they are still producing) to make space for the new vegetables. Before we plant we always feed the soil to help support the new seasons growth and productivity. To do this we do the following: top off the soil, check our irrigation, add worm castings, organic amendments, and mycorrhizal fungi to our soil.
We will miss our fall bumper crops, but look forward to all of the goodness and slower pace that the cooler season brings in the garden!
