Frequently Asked Questions


Arcadia plants: what should I do if I see powdery mildew on the leaves?
Powdery mildew on Arcadia shows up as a white, floury coating on leaves that can spread quickly in humid weather. Remove and discard the worst affected leaves, then improve airflow by spacing plants properly and avoiding overhead watering. Spray a labeled sulfur or potassium bicarbonate product early in the morning and repeat according to the label, especially if conditions stay damp.
How often should I water Arcadia during the main growing phase to keep the right soil moisture?
During the main growth (roughly weeks 3–8 after germination), keep soil evenly moist but never waterlogged—aim for the top 1 inch to dry slightly between waterings. In most home gardens this is about 1–2 deep waterings per week, increasing to 2–3 during hot, windy spells. Use a finger test: if the soil is dry 1–2 inches down, water thoroughly until moisture reaches the root zone.
How can I tell when Arcadia is ready to harvest at about 70 days?
Arcadia is ready to harvest when the crop reaches full size and the produce shows its mature color and firmness (no longer looks pale or soft). Check the plants around day 70: if you can gently press and it bounces back, it’s mature; if it feels underripe or watery, wait a few more days. Harvest in the morning for best texture and store promptly to maintain quality.
