Every region has micro-climates, so they have different zones, for example:
Medford, Oregon is USDA Zone 8a, 10°F to 15°F
Ashland, Oregon is USDA Zone 7b, 5°F to 10°F
You can check your area with this interactive map, click on your city and the zone pops up.
Always check USDA Zone on plants at the nursery, before you buy.
In Ashland, Oregon the last frost date is approximately May 15th.
Sow seeds in your greenhouse, or indoors, for transplanting after May 15th.

- Home remedy for Aphid Control: Mix a teaspoon of vegetable oil, a teaspoon of dishwashing liquid and a cup of water. Or, mix three tablespoons of liquid soap and a gallon of water. Spray to wet the entire plant thoroughly, particularly the undersides of leaves, because aphids must come into contact with the soap solution to be affected. After a few hours, wash off the oil and soap with a garden hose to protect sensitive plants. Repeat the application every few days as necessary.
- Control spittle bugs by blasting spittle bug foam off plants with water. Repeat as necessary.
