Tips and Tricks to Growing Rosemary Indoors and Outdoors Year Round

Does Rosemary Grow All Year? 


You can indeed grow rosemary and enjoy it all year long! Whether growing rosemary inside your home or getting ready to put it outside, we’ve got tips to make it even easier to grow all year.

Herbs Growing in PotsThe Pot and Soil

The plant’s pot is the first thing to consider because this is what the plant will call home. There are a few things to consider when finding the perfect pot for your rosemary:


  • Choose a pot with a depth that is the same height as your rosemary
    • For example, if a rosemary plant is about 6 in. tall above ground, the pot should be at least 6 in. deep
  • The pot should be wide enough to provide at least 1 in. of space between the edge of the pot and the roots
  • Make sure the pot has a draining hole and drainage pan
  • Use a well-draining potting soil

As the plant grows, you can increase the size of the pot according to the plant’s size.


The Drainage

Because rosemary prefers dry roots and absorbing moisture through the air, it is important that there is enough drainage for excess water.


  • Add a layer of gravel or small rocks to the drainage plan
  • This allows you to place the pot directly on the rocks
  • This helps prevent the potting soil from coming in contact with collected water in the drainage pan



Watering a rosemary plant can seem tricky since rosemary prefers dry roots, but it is important to water the plant properly! A few ways to do this are:


  • If the rosemary is outside, water two times a week
  • If indoors, water the soil every two weeks (always check that the soil is dry to the touch before watering)
  • Leave water in the drip pan with rocks because as water evaporates, the rosemary will absorb it
  • For indoor rosemary, have a spray bottle full of water, and spray the plant’s leaves once or twice a week—indoor air is typically drier than outdoor air



Rosemary does great with about six to eight or more hours of exposure to sun. Whether your rosemary is indoors or outdoors, make sure that it has plenty of time in sunlight.


If placing indoors, make sure it is in an area with plenty of windows and sunlight.





The best time to fertilize your rosemary plant is in the spring. Fertilize your rosemary 2-3 times during the month before you plan to put the plant outside for the summer.



Tips For Growing Rosemary Indoors in Winter:

When temperatures drop and frosts come, you'll probably want to move rosemary plants inside!


  • Keep rosemary out of humid areas indoors (such as bathrooms or the kitchen) to avoid powdery mildew from forming on the soil
  • Another way to reduce the risk of powdery mildew is by increasing the air circulation around the plant:
    • Let a fan blow on the plant on ‘low’ for a few hours a day
  • Outdoor sunlight exposure is more intense than sunlight exposure indoors, so make sure to place it in an area that receives plenty of sunlight
  • If you find that the sun the rosemary receives is still not enough, supplement the sunlight by shining a lamp with a fluorescent light bulb on the plantLightbulb.jpg


Gardening is a joy year round and even better is eating the fruit of your efforts all year long. Enjoy your rosemary!
