Tree collards are usually hardy down to around 15° F (-9.4 C) and have been successfully grown in Las Vegas with temperatures of 115+°! Tree collards don’t necessarily need to be staked, but if you want them to grow like a tree, you will need to provide a strong stake such as a T-stake or rebar to hold them up once they reach 2-3’ high. If left un-staked the ‘trunk’ will spread along the ground and send up numerous shoots that grow 2-3’ tall. Both methods work fine but if you are in a small back yard, you will probably want to stake your collards in order to maximize space. The taller the plant, the more likely it is to need staking. Storms or high winds will break branches. This is normal but can be mitigated by staking and pruning your plants regularly. Growing tree collards from seed is the best kept secret for getting tree collards that are more adapted to your climate. Your seeds may produce tree collards that tolerate or thrive in wider temperature swings than listed. They are also likely to be more adapted to your soil, humidity, or arid climate.

Tree collards thrive best in the ground but can be grown in large pots (15 gallon minimum) with high quality potting soil. They appreciate applications of calcium, such as ground oyster shell or gypsum, 2x a year, and mineral rock dust once a year for micronutrients. They need moderate to low water and full sun in more temperate climates and protection from hot afternoon sun in hot times of year.

These seedlings may or may not eventually flower. Flowering is not a sign of dying. Not all tree collards bloom, but if they do, you can eat the flowers as you would broccoli. Eventually, you need to let them bloom and set seed. You may not get many edible leaves at that time (2-4 months) As the seeds mature into pods, you can remove them to help your plant go back into leaf production.
