Q: I’m planting my fall garden, but it’s so hot outside! What can I do to help seeds germinate when I plant them in hot summer soil?
A: Most annual vegetable seeds germinate readily in soil temperatures ranging from 70 to 90 degrees Fahrenheit. But in midsummer, soil temperatures can be at the high end of that range — or above it — making it tough to get good germination for some crops. That includes lettuce (ideal germination temperature is 75 degrees), spinach (70 degrees), peas (75 degrees) and beans (80 degrees).
