Tuber Dormancy & Preparation
4-12 weeks depending on storage and start timeTubers are dormant and should be stored in a cool, dry place. Look for viable eyes (growth points) on the tuber.
Store tubers at 45-50°F in peat moss or sand. Check periodically for rot and remove any diseased portions. Start tubers indoors 4-6 weeks before last frost.
Sprouting & Early Growth
2-4 weeksEyes begin to sprout, producing small shoots with emerging leaves. Plant develops initial root system.
Plant tubers indoors in seed-starting mix 4-6 weeks before last frost, or direct plant outdoors after frost danger passes. Keep soil warm (65-70°F) and moist. Provide bright light to prevent leggy growth.
Vegetative Growth
3-4 weeksPlant develops sturdy stems and multiple compound leaves. Compact mounding habit becomes apparent.
Pinch off the central growing tip when plant is 6-8 inches tall to encourage branching and bushier growth. Water consistently and fertilize every 2 weeks with balanced fertilizer. Monitor for pests.
Budding & Flowering
4-5 weeks until peak bloomFlower buds appear in clusters at branch tips. Small pompom-style purple flowers develop and open.
Continue regular watering and fertilize with higher-phosphorus formula to encourage blooms. Deadhead spent flowers regularly to promote continuous blooming. Support stems with stakes if needed in windy locations.
Peak Bloom & Decline
6-8 weeks or until first frostMaximum flower production; blooms cover the compact plant. As temperatures cool in fall, blooming slows.
Continue deadheading for prolonged bloom. Reduce fertilizer in late summer. Prepare for frost by monitoring weather. In frost-prone zones, dig tubers before first frost and prepare for storage.
