(Best months for growing Rosemary in New Zealand - cool/mountain regions)

  • P = Sow seed
  • Easy to grow. Plant cuttings . Best planted at soil temperatures between 15°C and 20°C. (Show °F/in)
  • Space plants: 100 - 150 cm apart
  • Harvest in approximately 1 years. In warmer areas, harvest time might be shorter.
  • Compatible with (can grow beside): Beans, Carrots, Cabbages, Sage
  • Avoid growing close to: Potatoes
  • Prostrate Rosemary

Rosemary will grow from seeds but this is not recommended as the success rate is very low. Small cuttings are easy to grow. Put in light, sandy soil where you want your plant to grow or start in small pots and plant out when established.

Rosemary comes from warm Mediterranean areas but adapts well to colder climates. In areas of heavy frost, a cutting potted up and kept in a sheltered spot will insure against total loss of your plant over winter.

Dryness suits rosemary, so well-drained soil and sunshine will be best.

Once established rosemary can be harvested all year round.

Rosemary grows well in patio pots or tubs.

Culinary hints - cooking and eating Rosemary

Leaves sprinkled on roast potatoes, meat and barbeque food make them extra tasty.

Rosemary can also be used to add flavour to vinegars and oils.

I placed rosemary cuttings into a glass vase of water and they shot roots in a few weeks. Then I planted in pots in soil.

Hi, I have a rosemary plant which is few months old. I prune it quite often but it looks very dry and unhealthy. What should I do to get it back to look healthy? Thank you. Mithila

My rosemary bush is 15 years old. I use it for cooking. It ihas very woody stems. It is quite large. Can I prune it and will it shoot from cut stem?

rosemary will handle very harsh treatment and still grow strong I prune mine off regularly with a chainsaw to 1/3rd of their size or less every couple of years and trim them up in between with the same method. I chopped one down to virtually nothing 3 years ago it is now about 4 ft around in every direction, and it was not much more than a stump. pruning them hard gets rid of the dead wood and makes them more bushy so you get more of the tender shoots that are good for cooking.

I want to plant rosemary or another fast growing plant in a plater box approx 700mm long by 300mm x 300mm is this sufficient

I need some advice re treatment of mildew (white film) on my rosemary leaves I planted them in pots on a north facing balcony, they are probably 3 months old, so far they have been doing great but up until 1 week ago I noticed this whitish film/ or cotton-like covering some leaves, can anyone suggest any treatment?? I've read so many different things on different forums I just want to get a better plan of action Thanks Andrew

Sounds like mites, spray with pyrethrum or white oil and water them less if it is mildew. Rosemary likes a semi arid environment. white oil should help with insects and mildew somewhat or even try olive oil sprayed on it lightly
