August Garden Calendar

August Garden Calendar

posted in: Garden | 0

August is one of my favorite months to garden in. For one, I love that we can just eat our way through it!  I love the sun kissed smell of the earth as I crunch over the hot redwood needles. This is called forest aromatherapy creating instant peace of mind. I love finding the seed heads popping as they are always full of promise and hope. I collect seeds and plant cuttings wherever I go and sometimes forget that I have put them in my pocket only to find them later. August also brings the  annoying pesky yellow jackets who are always butting in.  Watch out for them near water sources..

But this time of year is also a magical time of year to play in the garden…so much activity going on-flowers blooming, insects humming, critters crawling, but all at a really lovely pace.

Tomatoes are on autopilot, the cucurbits are cranking, corn and beans are growing taller by the minute. I truly am enthralled with life when I am in my garden. Aside from watching in amazement, my absolute favorite thing is to experience the hummingbirds as they come and check out the spray coming from my hose nozzle. So whether your connection to the plant and animal kingdom is via a planter box on a windowsill or a dream organic veggie garden, enjoy the outdoors, connect to nature, and get your hands dirty!

For this month, breath deep, get your hat on, crank up the tunes and read the garden calendar below to find out what can be sown, planted, and harvested in August plus much much more! Enjoy!
