Frequently Asked Questions

How do I prevent and treat powdery mildew on Blue Solaise plants?

Blue Solaise (tomato) is prone to powdery mildew, especially when nights are cool and days stay humid. At the first white, dusty spots on leaves, remove heavily affected leaves, improve airflow (space plants well and avoid crowding), and spray a labeled potassium bicarbonate or sulfur product in the evening per package directions. If spread continues, switch to a systemic fungicide labeled for powdery mildew and stop overhead watering so foliage stays drier.

How often should I water Blue Solaise during the main growing phase?

From flowering through fruit set, water deeply about 1–2 times per week, aiming for consistently moist (not soggy) soil around the root zone. Water when the top 1 inch of soil feels dry; if you can press the soil and it crumbles, it’s time to water, and if it feels wet/compact, wait. Keep watering steady—irregular watering is a common trigger for cracking and blossom-end rot in tomatoes.

When is Blue Solaise ready to harvest?

Harvest Blue Solaise when fruit has full color and is slightly soft at the blossom end, typically around 110 days from sowing depending on transplant timing. For the best flavor, pick after the skin is uniformly dark (not green) and the fruit gives a gentle squeeze without feeling hard. Avoid leaving fruit to overripen on the vine, as late-season softness and splitting increase as temperatures fluctuate.

Cool and captivating, Blue Solaise leeks bring a silken, ocean-deep flavor with a gentle sweetness that lingers—each stalk is tender and richly textured, with a firm, crisp bite. At maturity, the long, upright shafts form a clean, well-blanched look that’s ideal for roasting, simmering, and velvety sauces, as well as pickling for a bright, briny accent. Grow 110 days for a steady harvest of elegant, blue-green stems that turn the garden into a palette of slate and steel.

Sowing Tips

Transplant Conditions

Wait until soil reaches 45°F and nights stay above 28°F before moving outdoors. Harden off for 7 days first.

Expert Note

For the sweetest, most tender white portion, transplant at the right time and keep hilling/adding soil around the stems as they grow.
