Growing Indoor Plants Outdoors

Hardiness Zones

Before you start: This guide has been very useful in helping us transition "indoor" plants outside, and we hope it's useful for you, too!
However, there are many other factors influencing growth and the ability of a plant to tolerate or thrive in an environment that also need to be considered. It's best to research the plant type, learn where it's from and understand the conditions it needs to thrive.
We also recommend making transition in spring when temperatures are mild - never in the middle of winter or summer. Potential exposure to sun, cold, wind and altitude need to be carefully considered.

How to Use

Hardiness zones provide a guide for gardeners by helping them determine which plants are able to tolerate the temperatures in their specific area. The zones are determined by the average annual minimum winter temperature of their geographical location.

1. Determine your hardiness zone by searching your location on the list below

2. Identify the hardiness of the plant type you have by Google searching the plants name followed by "hardiness zone"

3. If your hardiness zone is number is higher than the hardiness of your plant, you can consider transitioning this plant into your garden.

For example, you live in Auckland (zone 10b) and would like to keep your Fiddle Leaf Fig outside. The Fiddle Leaf Fig has a hardiness of 10-12, and Auckland has a hardiness zone of 10b. In the right position, this plant should thrive.
