Every year I am determined to start a fall garden, it's just so easy to let all of springs efforts burn to a crisp while sitting under the air conditioner but then as fall cools off and you survey what could have been a great crop of fall veges regret sets in! So get out there in the "cool" of early morning and evening or work in short spurts if you must work in the heat and keep those tomatoes watered and picked and start your fall crops! You should have some sort of watering system that just requires you to turn on the faucet and your drip hoses will do the rest. August will require water and you won't want to stay out in the heat too long so make basic tasks like watering easy with drip hoses and mulch. Newspaper, straw, grass clippings and mulch from the green waste site on 56th street north (east of Mingo west of highway 169) all help keep the soil cool and moist. As fall sets in we will want your bags of leaves for Cherokees vegetable garden. We might also compost right in the beds to some degree, we do need more organic matter to help our soil retain moisture better and increase fertility.

I have cleaned out one bed at Cherokee and planted squash and beans while using the lettuce which had gone to seed as part of the mulch. I would love to have some volunteers to help keep the tomatoes going so the students can come back to school and find a beautiful crop of yellow pear tomatoes, the plants will stop producing if we don't keep them picked and watered. Obviously your reward for weeding and watering can be handful of tomatoes!

OSU extension is a great source of gardening information, they should be on your favorites list!
