Frequently Asked Questions

How do I prevent and treat downy mildew on Boro (spinach-like greens) in humid weather?

Boro can get downy mildew when leaves stay wet—watch for yellow patches on the upper leaf surface and gray-purple growth underneath. Improve airflow by thinning plants and watering only at the soil line in the morning, then remove the worst affected leaves. If it’s spreading, use an appropriate labeled fungicide for downy mildew on leafy greens and reapply according to the label after rainy/humid spells.

How often should I water Boro during the main growing phase to keep it sweet and non-bitter?

During the peak growth period (roughly weeks 3–6), keep the top 1–2 inches of soil consistently evenly moist, not soggy. Water about 1–2 times per week depending on heat, giving enough to wet that 1–2 inch depth; in hot or windy weather you may need more frequent watering. If the soil dries out between waterings, Boro can turn tougher or more bitter, so check moisture with your finger before watering.

When is Boro ready to harvest—what size and signs should I look for?

Boro is typically ready around 60 days from sowing, when leaves are fully developed and look tender and firm rather than small and sparse. Harvest individual outer leaves as soon as they’re large enough to eat, or do a full cut once the plant has a dense rosette. If leaves begin looking thick or getting tougher, harvest promptly to keep flavor mild.

Sweet, earthy-sweet beets with a velvety, deep-red interior—Boro delivers a rich, uniform color that feels almost jewel-like in the garden. Expect tender, fine-grained roots with a smooth, crisp bite, ideal for roasting to intensify their natural sweetness or for fresh use where their color and flavor shine. A dependable 60-day performer, Boro is a standout choice for gardeners who want consistently beautiful red beets from sowing to harvest.
