01 · Light & site
Give it the light its growth depends on.
Full sun, with roughly 6 to 8 hours of useful light. Warm soil and frost-free conditions
02 · Water & soil
Keep roots supplied without trapping water.
Water the complete root zone, then recheck conditions before watering again.
- Soil
- Loose, organic garden soil
- Drainage
- Well drained
- pH
- Species-dependent, commonly mildly acidic to neutral
03 · Spacing & roots
Make room for the mature plant.
Space plants about 18 inches apart. Expect a mature plant around 12 inches tall by 48 inches wide.
Spreading roots or runners can extend beyond the visible crown.
04 · Start
Begin with the method that protects establishment.
Plant disease-free slips after soil and nights are reliably warm.
05 · Care
Support healthy growth through the season.
Usually self-supporting at the stated mature size. Add a discreet stake only if wind, bloom weight, or an exposed site makes it necessary.
- Upkeep
- Moderate
- Feeding
- High
- Watch for
- Wireworms, Flea beetles, Voles
06 · Flower or harvest
Harvest and maturity
90 to 120 days. Use the seed packet or plant label for cultivar-specific timing and harvest cues, then adjust for temperature, light, and the stage you intend to pick.
07 · Safety
Know the cautions before you place or use it.
- Confirm cultivar, regional timing, and toxicity or food-use details with local extension guidance.
- Keep unknown plant parts away from children and pets.
