Frequently Asked Questions


Big Max (110 days) — how do I manage powdery mildew if it shows up on the leaves?
Powdery mildew on Big Max usually appears as a white, dusty coating on older leaves, then spreads through the canopy. Remove and compost the most affected leaves early, and water only at the soil line so foliage stays dry. Spray a labeled horticultural fungicide or sulfur-based product as soon as you see early spots, and repeat according to the label to protect new growth before the vines fully cover the bed.
How often should I water Big Max during its main growing phase (vines filling out and fruit developing)?
Aim to keep the root zone evenly moist but not waterlogged—about 1 to 2 inches of water per week total, adjusting for heat and rainfall. During fruit development, check soil 2–3 inches down; water when it feels dry at that depth, and then water deeply so the moisture reaches the thickest roots. Avoid frequent light sprinkling that keeps the surface wet, which encourages foliar diseases on Big Max.
When is Big Max ready to harvest, and how can I confirm it’s mature?
Harvest Big Max when the rind is fully hard and the surface looks matte and evenly colored, not glossy-green. The vine should be starting to die back, and the stem at the fruit (where it attaches) should be drying and turning corky. If you can’t puncture the rind with a fingernail and the pumpkin sounds hollow when tapped, it’s ready for cutting—then cure promptly for better storage.

Sowing Tips

Transplant Conditions

Wait until soil reaches 65°F and nights stay above 55°F before moving outdoors. Harden off for 10 days first.

Direct Sow Preferred

Sensitive roots — does not transplant well. If starting indoors, use biodegradable pots and disturb roots as little as possible when moving outdoors.

Expert Note

For best giant-pumpkin results, start with a deeply warmed, compost-rich bed and keep a single strong vine while feeding heavily once plants flower.
