Mint and sage are hardy and should be OK outdoors now after hardening off. Basil needs heat. Here in the U.K. I actually keep it under glass all summer. Lemon grass is a tropical plant and also needs heat. Minimum 5c in winter and hot summers.

Thanks so much! Apologies if this is a dumb question but I'm really new to outdoor gardening. Are these herbs perennials? If yes, would they be OK in a planter boxes over the winter and come up again next summer? I know in ground mint and chives come back, but not sure about the rest. Should I bring them indoors? I do have some indoor herbs growing. I plan to keep those indoors and get the outdoors through friends or store. I also received some oregano too that I planted in a container. Unfortunately, it's gotten cold as of late.

Also would most stores now carry herbs now and would grocery store quality be good enough to plant or should i go to a nursery?

Thanks in advance :)

All the ones you list, except basil, are perennials botanically speaking.

Of the perennials, Lemon Grass would need to come indoors in winter. All the others can stay outside all year round but some will die down in winter.

Buy from a nursery or garden centre. Grocery store herbs are forced into lush rapid growth in greenhouses and are designed to be short lived ingredients in the kitchen, not sturdy outdoor plants.

When you are Googling for information check each specific herb individually. Although we talk about 'herbs' as a category, they are all different and do not all have the same requirements.

Hello,

You can start planting Sage on early spring before the flowering period and keep it safe from cold and too much moisture all yeat long. Basil won't last for winter except you choose a winter basil to grow indoor. Mint is generally a durable herb, its perennial so you will see it every spring starting to grow again. Mint and basil, you can start planting during spring and early summer. About lemongrass I have no knowledge!

Try planting oregano and lavander too, they are perennial, easy to take care and just avoid watering too much after the first year of life. The same applies to the sage. Too much water will kill them
