My family and I have been trying to grow rosemary for a few years but we can't seem to get them through the winter. We know they can grow well here as there are plenty outside the shops around town but ours can't seem to survive long enough to get established. We tried wintering them in the garage this year as we have cats and can't keep them inside the house itself but it didn't seem to make a difference. Is there a variety that's better suited to my zone that might have a better chance, or are there any tips that might help me keep these plants going?

Is it possible they're getting too much water and/or your soil doesn't drain quickly enough? Rosemary is pretty tough and drought tolerant but it doesn't like being soggy too long, especially in cooler weather. Try adding more grit to the soil so the rosemary can dry out between waterings. You might also ask one of those shops if you can take a few cuttings from their plants, as rosemary is pretty easy to propagate from cuttings, and that way you'd know you have a variety that does well locally. They should be happy to let you, as rosemary needs to be pruned regularly anyway.

Read the notes here, there are several tips to follow. Like do not overwater them especially in winter, they are a bit of a tough hardy plant, so don't water as much as some other plants. Have good free draining soil not heavy clay soil. They like sunshine so don't put in a garage, most plants need heaps of sunlight. And if you have lots of frost best to do a few cuttings for the next year.

When is the best time to prune a Rosemary bush in Australia.

Probably anytime of the year but more so when it is in a growing stage. The gardens I go to, it is a hedge so it is trimmed often.

I am in zone 9b. Will rosemary survive all day, 10+ hours of summer sun?

We have rosemary planted in the ground. We have had it in full sun as well as in partial shade - it thrives either way. Rosemary will get to be at least three feet tall and may create 3-4 foot diameter bunches so be sure to give it some space.

I live in zone 9b, and I have one Rosemary in a container growing nicely. It is a hassle-free herb. I have it outside in a full sun area. I just make sure it gets its water. I also have Basil, this is in partial sun area. It is also a hassle-free herb. Just protect them from bugs.

It should love that! Make sure it has a gritty, well-draining soil (nutrient-poor is fine), and give it a good soak about once a week, or every few days in a major heat wave. Rosemary is a very tough, easy-to-care for plant once established.

Rosemary - I cut some small new growth into jars about 10 cm long with the bottom couple of centimetres removed and put about a centimetre of water in the jar. Within 2 weeks they have roots ready to plant out.
