PLACEMENT & CULTIVATION
Borage is a vital plant for bees, as its starry blooms continuously refill with nectar. In vegetable gardens, it makes a fantastic companion plant for strawberries, tomatoes, squash, bush beans, and lettuce. To encourage bushiness, pinch back the plant early and deadhead to prolong blooming, but leave some flowers to self-sow. The edible blue blossoms look enchanting when frozen inside ice cubes that slowly melt in your summer drink.
Not particular about soil pH. Neutral and Alkaline
Mix a few inches of compost into the soil prior to planting. Supplement with an organic or liquid fertilizer according to package instructions, if desired or if soil is poor.
Diseases & Pests:
Avoid powdery mildew by spacing properly and in a location that has decent air circulation.
