  • Soil condition required for maintaining healthy plants are nutrient rich, well-drained and water-retentive soil. However, if your garden soil is very heavy, consider making raised beds.
  • Supplement organic matter and prepare soil before spring. As soon as spring arrives, sow seeds directly in garden soil. Do not cover borage seeds, as they need light exposure for germination. Lightly water them to induce quick germination.
  • Leaving a space of about 1 foot between two plants is sufficient for growing in groups. Accordingly, thin out the young plants. Ensure that there are no competing weeds with your newly germinated plants.
  • Water the plants on a regular basis. Once established, you can harvest the mature leaves. During summer, you can cut back the stem for promoting a bushy growth.
  • Consider collecting your own seeds and use them for propagation. Borage seeds stored in an airtight container are viable for three years.
Some plants are benefited by growing in proximity to each other. With borage species, several cultivars including tomato plants, strawberries, and leafy vegetables are identified as the best companion plants. When grown together, the borage herb reduces the infestation of diseases to these plants and increases their yield.
