Seed Piece Sprouting
2-3 weeksSeed potatoes are planted and begin developing sprouts. Soil temperature should be 45-50°F minimum for sprouting to occur.
Ensure well-draining soil and moderate moisture. Keep soil temperature consistent. Plant only certified disease-free seed potatoes.
Vegetative Growth & Emergence
3-4 weeksSprouts break soil surface and develop first true leaves. Plants grow rapidly with increasing foliage development.
Hill soil around plants as they grow to prevent tuber exposure to light (which causes greening and solanine toxins). Water consistently. Apply mulch to retain moisture and suppress weeds.
Flowering
3-4 weeksPlants produce white or light pink flowers and continue canopy expansion. This indicates tuber development is actively occurring underground.
Maintain consistent watering and avoid overhead irrigation to prevent foliar diseases. Continue hilling if needed. Monitor for pests and early blight symptoms.
Tuber Bulking
4-6 weeksFoliage is fully developed and dense; most plant energy is directed to tuber enlargement. Tubers reach marketable size.
Keep soil evenly moist (critical for good yields and shape). Avoid severe stress or water fluctuations which can cause misshapen tubers. Provide supplemental fertilizer if needed.
Maturation & Harvest
2-3 weeks after vining stopsFoliage yellows and dies back. Tuber skins set and toughen. Bonita potatoes reach full size and are ready for harvest.
Stop watering 2-3 weeks before harvest to harden skins and reduce bruising. Harvest when foliage is completely dead. Cure in cool (50-60°F), humid conditions for 10-14 days before storage.

Common Pests
-
Hand-pick adults and egg clusters; use floating row covers; apply spinosad or neem oil; encourage natural predators like ladybugs
-
Use reflective mulches; deploy yellow sticky traps; apply insecticidal soap or neem oil; maintain good air circulation
-
Use yellow sticky traps; spray with insecticidal soap or horticultural oil; encourage parasitic wasps
-
Strong water spray to dislodge; insecticidal soap; neem oil; encourage beneficial insects like ladybugs and parasitic wasps
-
Remove infected lower leaves; improve air circulation; mulch to prevent soil splash; apply copper fungicide or chlorothalonil; avoid overhead watering
-
Remove affected foliage immediately; apply copper-based or mancozeb fungicide; ensure proper spacing; avoid overhead irrigation; plant resistant varieties
-
Use certified disease-free seed potatoes; maintain pH below 6.0; avoid fresh manure; ensure consistent soil moisture; practice crop rotation

Harvest Tips
Bonita potatoes are ready to harvest 90-110 days after planting, when foliage has completely died back and tubers are fully sized. Dig carefully with a fork to avoid bruising the thin-skinned tubers. Harvest in cool, dry weather if possible. Cure harvested potatoes in dark, humid conditions (50-60°F, 90%+ humidity) for 10-14 days to harden skins before storage. Store at 45-50°F in dark conditions for long-term keeping.
Fun Facts
