Best Climate to Grow: Borage is a hardy little herb that does well pretty much anywhere.
Light Requirements: Full sun to partial shade.
Soil Requirements: Rich, fertile soil that is kept moist encourages the growth of leaves, while lesser, drier soils will encourage flowering. pH level can range from acidic to alkaline without affecting the plants.
Feeding and Water Requirements: That depends on why you are growing borage. See the previous section about soil requirements. Drip irrigation and mulching are not recommended for this herb – too much moisture can cause root rot in borage.
When to Plant: Sow directly in the ground from Spring to early Summer. Borage doesn’t transplant well due to the long taproot.
Planting Depth and Spacing: Sow the seeds ½ inch deep and 12 inches apart in rows that are 12 inches apart. If broadcasting over a block of garden space, you will need to thin the seedlings to 12 inches all around.
Container Requirements: Borage grows very well in containers at least 8 inches deep. We suggest growing a few borage plants in the center of a large container, surrounded on the edges by smaller, complementary herbs. Mix compost into the soil before planting, and water occasionally, making sure the plants don’t completely dry out.
Harvesting and Storage: Both the leaves and flowers are edible, often used in teas or salads and light stir-fries. The flowers can also be candied, or frozen in ice cube trays to add to iced tea or other, stronger drinks during the summer. Snip the leaves with garden shears as needed, starting with the lower leaves. Harvest the flowers for eating before they form seeds.
Harvesting Seeds: Borage seeds are relatively easy to harvest – they’re highly visible, for one thing. Allow the flowers to mature and form seeds. Wait until the seeds turn brown – there are three seeds per flower – before removing the flower head with the seeds. The trick is to collect the seeds after they have turned brown but before they have fallen out of the flower. Simply store them in a cool, dry place until time to plant again.
Pests to Monitor: Generally pest-free; in fact it is often used as a companion plant to repel pests from other plants.
