I have a large terra-cotta pot filled with Rosemary. Can I leave it in the pot next to the garage, facing south for the winter? Should I take the plants out and plant them in the same location? Our soil here near New Liseard, Ont. is sandy. Not allowed to take plants back to U.S. Thanks, E

would like to plant "pinkie" rosemary bush in ground, will it grow in this zone and what precautions would I take for the winter?

We planted a Rosemary plant that gets full sun. The leaves are still dropping after a month. Can you please advise what to do. The plant is about 65cm high. Many thanks.

I saw where you can make a hedge out of Rosemary. Would this be a good suggestion? I have several plants I started from seed because I would like organic herbs. I plant on planting it in my garden as an entrance hedge. Need to know if I am heading in the right direction with this herb. We have four seasons here. Trying to make long lasting decisions. Thanks

Hello... I wanted to do a mass planting of lavender and rosemary with 5 or so kangeroo paws in a corner. I was hoping that because both lavender and rosemary were from the Mediterranean area, this would work. Do I follow the 'rules' for planting rosemary, for lavender. Do you happen to know if the kangaroo paw would be okay amongst them?

Have for 8 years had lavender and rosemary alongside each other with no problems. Bees love their flowers. Never had any success with kangeroo paws neither did my neighbours, it must be our soil. Live in Leichhardt, sydney and we also don't have any luck with azealeas.

I am originally from NJ, USA. I now live in Costa Rica. When I lived in NJ Rosemary loved the summer months in that partially shady area I kept it, but once I brought inside before frost, it almost always got the powdery white on it as you describe. It is called powdery mildew and it can be easily controlled by mixing a teaspoon of baking soda in a pint of water...once dissolved, spray it on the plant every few days until the problem goes away. Mildew loves acid environments and the bicarb makes it alkaline, killing the mildew but not harming the Rosemary.

Where can I buy Rosemary seeds in NZ.

Gwenn, Put your question in a Google search. Here are three places that came up early when I tried it: oderings.co.nz/Shop/Oderings-Plants/Herbs-Cooking-Fresh/Herbs-Cooking-Fresh-__I.84__C.24353 gstuff.co.nz/shop/garden/index.php?main_page=product_info&products_id=806 egmontseeds.co.nz/herbs/rosemary You will probably also find them in your local garden centre e.g. Mitre10, Bunnings, Placemakers, will have them, as do some supermarkets.
