When to transplant greenhouse perennial herbs?
After having very limited success with herb seeds last year, i purchased greenhouse grown herbs from a couple different merchants in hopes of having better luck this year... My question is, WHEN IS IT SAFE to plant them outside? They are all perennials, Mints, greek oregano, french tarragon, winter savory, lemon balm, purple sage... i have been placing them out in the sun during the day but it is still going down to around 35 degrees at night here and we are surely going to be getting a couple more frosts. A friend told me it is probably safe because they are all perennial in my zone, but i really want them to succeed this year so i am hoping someone here will know when it's totally safe to put them in the ground, not probably safe:)... Thank you in advance for any input, it is greatly appreciated:) Best regards~
