FAQs
Can I plant warm-season crops in August in Columbus?
August is generally too late for warm-season crops like tomatoes and peppers, as they need more time to mature before frost.
How can I extend my growing season into fall?
Start cool-season crops indoors in August and transplant them outside, and use row covers to protect plants from early frosts.
Is it better to plant in raised beds or containers in August?
Both work well; raised beds warm up faster and drain well, while containers offer mobility to optimize sunlight and protect from pests.
How often should I water my garden in August?

Look out for aphids, squash bugs, and flea beetles, especially on leafy greens and brassicas.
