Spring is here, can I plant my seeds?
Planting vegetable seeds depends on your last
average frost date and the temperature of your soil.
Your growing season, which is determined by first frost (fall) and last frost (spring), is the amount of time vegetables in your garden have to ripen before a fall frost.
For example: Medford, Oregon, Zone 8a, Average Frost Dates Spring 4/25, Fall 10/20. Average growing season 6 months
but Ashland, only 11 mile away…
Ashland, Oregon Zone 7b, Average Frost Date Spring 5/15, Fall 10/15. Average growing season 5 months
Check your local Extension Service for frost dates and USDA Zone.
Each zone has different planting schedules for different plants and your local extension service will have this information – often it’s online. Then check the back of your seed packets. It tells you when to direct sow and days to harvest.
Check Page 7 of the Oregon State University pamphlet Growing Your Own for “Dates for planting vegetables in Oregon”. It’s a very handy booklet.
