Frequently Asked Questions

How do I manage powdery mildew on Black Vernissage (60-day) during warm, humid spells?

Check leaves weekly for a pale gray-white powder that starts on lower foliage and spreads upward on Black Vernissage. Remove and trash the worst affected leaves early, then water only at the soil line (not on leaves) and increase airflow around plants. If it keeps recurring, spray with a labeled sulfur or potassium bicarbonate product, following the label’s reapplication schedule.

How often should I water Black Vernissage during the main growing phase to prevent stress?

From about transplanting/sprout establishment through the next 4–5 weeks, keep soil evenly moist but not soggy—aim for the top 1 inch to dry slightly before watering again. In full sun, that usually means watering every 2–3 days, but increase to daily during hot, windy weather. Stop frequent light watering once plants set up and instead water deeper to encourage steady growth.

When is Black Vernissage ready to harvest, and what signs should I look for?

Harvest at about 60 days when bulbs/heads reach their stated size for your variety and feel firm with a smooth, well-formed skin. Check by gently lifting one plant—ready roots/bulbs should be fully developed, not soft or hollow. For best quality, harvest on a dry day and avoid pulling if the stems are still loose or the skin hasn’t tightened.

Velvety, inky-sweet flavor leads the way with Black Vernissage cherry tomatoes—fruits that ripen to a dramatic mahogany-black with a subtle, smoky depth. Bite into a firm, juicy pop with a glossy skin and a balanced, garden-fresh sweetness that shines in every bowl. Ideal for fresh snacking, vibrant salads, and striking garnishes, these 60-day performers bring gourmet color and rich taste to the patio garden.

Sowing Tips

Transplant Conditions

Wait until soil reaches 60°F and nights stay above 50°F before moving outdoors. Harden off for 9 days first.

Expert Note

Start indoors early but transplant only once soil is consistently warm (about 60°F+) to prevent cold-stunting, then stake for airflow and even ripening.
