Red Rubin Basil

Basil

65d to harvest

Aromatic as a summer breeze, Red Rubin Basil unfurls velvety, ruby-tinged leaves with a peppery-sweet perfume that lingers in the air. Expect tender, medium-sized foliage with a lush, slightly ruffled texture—ideal for fresh bouquets of flavor and for turning into fragrant sauces, pesto-style blends, and quick infusions. Grow it for its striking color as much as its bold Italian basil character, with plants that hold their beauty through the warm season.

Frequently Asked Questions

How do I prevent and treat downy mildew or botrytis on Ocimum basilicum (Red Rubin basil)?

Look for yellow patches on upper leaves, fuzzy gray growth on the undersides, or gray mold on stems—these are common in basil, especially with cool nights and persistent humidity. Remove and discard affected leaves immediately, improve airflow (space plants and avoid crowding), and water at the base so foliage stays dry. If it keeps spreading, use a labeled fungicide effective for basil downy mildew and follow the label’s timing, since repeated applications are often necessary under humid conditions.

When is Red Rubin basil (Ocimum basilicum) ready to harvest?

Start harvesting around day 45–55, and plan full harvest by about day 65 when plants are bushy and the leaves are well-filled. Pick individual leaf clusters or cut stem tops just above a pair of healthy leaves to encourage branching. The best harvest is when leaves are tender and fragrant—if leaves become noticeably tougher or flowering starts, flavor can shift and you should harvest promptly or pinch to delay blooms.
