Whether you grow them from seed and add the sprouts to your salad, or grow them to maturity, you’ll find these plants are well worth the time and space in your garden.

Where is the chia plant grown?

Chia plants are annual plants native to Central America. It grows best in warmer climates such as in the southeastern United States or in USDA Hardiness Zones 8-11. The chia plant can reach 3 to 5 feet in height and several feet wide in one season, so it needs a site with plenty of space.

How and when to plant a chia plant

Growing chia plants from seed is easy in areas with mild winters. In the fall, soak chia seeds in water until their gelatinous coating absorbs as much water as possible, after which they look like frog eggs. Use a spoon to scoop two to three seeds and place them on the surface of a prepared garden bed about three feet apart. Cover the seeds lightly and water daily until they germinate and begin to grow vigorously in five to seven days.

Chia plant care tips

Once established, chia plants are very low maintenance.

a light

Chia plants need at least eight hours of full sun per day.

soil and water

Chia plants tolerate a wide range of soils from sandy to loamy, but the soil must drain well or the roots may rot.

Seedlings and young plants need plenty of water. After the plants have established full root systems, they are drought tolerant and thrive in the midday heat. Allow the soil to dry out between waterings to help avoid root rot.

temperature and humidity

Chia plants grow best in warm weather with a temperature between 70°F and 85°F. They can survive temperatures as cold as the 50s but not extremely cold. Chia plants do not have strict moisture requirements but have been known to do well in high humidity environments.


Chia does not require fertilization when grown in rich soil. In poor soil, dig in some compost at planting time.

Potting and repotting chia plants

Chia plants can be grown indoors in containers, but they require at least six hours of direct sunlight per day, so they need a sunny window or grow lights. Select a terra cotta pot with good drainage and fill it with commercial potting soil with some sand added. This annual does not require repotting; Just start over with fresh seeds and soil in the same pot each year.

Pests and problems

One particularly great aspect of chia plants is their disease tolerance, which makes them good for sustainable farming practices, especially in desert regions. Any pests that attack can often be treated with a mild organic pesticide such as neem oil.

How to propagate a chia plant

Chia plants are prolific self-seeders, so they will produce a new crop of plants each year without assistance.

Harvest tips

To harvest seeds for future crops (or to eat!), snip the blooms at the end of the season after they have dried out and the petals have fallen off. Place the flowers in a paper bag to hold the seeds. When completely dry, crush the seed heads in the bag to dislodge the seeds.
