Planting Guide For Zone 7
When Can I Plant My Peas, Broccoli, Cabbage
Benton and Franklin Counties are considered Zone 7 with an average last frost date of April 15th and first frost date of November 15th. These dates will vary a week or two so it is important to watch the weather before planting.
Use your last and first frost dates to calculate your planting schedule. For Kennewick, Each winter, on average, our risk of frost is from October 17 trough April 15. You are almost certain that you will receive frost from November 1 through March 23. You are almost certain that you will not get frost from April 21 through October 2. That gives you a frost-free growing season around 193 days.
Using the planting schedule below will help you get the most our of your garden. Starting seeds indoors before your last frost date will give you a jump start on the growing season. Knowing when to transplant seedlings outdoors will help to maximize your harvest.
