Seedling
2-3 weeksTiny seedlings with cotyledons emerge within 7-10 days. True leaves begin to appear with characteristic fine, feathery foliage.
Keep soil consistently moist but not waterlogged. Provide bright light to prevent leggy growth. Thin seedlings to prevent crowding.
Vegetative Growth
2-4 weeksPlant develops bushy, mounded form with increasingly dense finely-textured foliage. No flowers yet; plant focuses on establishing root system and branching.
Pinch back growing tips to encourage bushier growth and more branching. Water regularly but allow soil to dry between waterings. Begin light fertilizing.
Budding
1-2 weeksSmall flower buds begin to form at branch tips. Plant reaches its mature compact size (typically 12-18 inches tall).
Maintain consistent watering and feeding schedule. Deadhead any early flowers to encourage more blooms. Reduce nitrogen fertilizer if excessive foliage growth occurs.
Flowering
8-12 weeks (or until frost)Abundant small (1-2 inch) golden-yellow double or semi-double flowers bloom prolifically. Plant is full, mounded, and covered with blooms.
Deadhead spent flowers regularly to promote continuous blooming. Water at soil level to keep foliage dry and prevent mildew. Apply balanced fertilizer every 2-3 weeks.
Decline/Frost Sensitivity
2-4 weeks before frostBlooming slows as temperatures drop below 50°F. Plant may show yellowing foliage and reduced vigor. Dies back completely at first hard frost.
Continue deadheading to extend season. Collect seed if desired before hard freeze. Plant is frost-tender; does not overwinter in cold zones.

Harvest Tips
True Gold is primarily ornamental, not harvested for food. Deadhead spent flowers regularly by pinching or cutting just below the flower head to encourage continuous blooming and maintain compact shape. For seed collection, allow a few flowers to remain on plant until they dry and seeds mature (4-6 weeks after flowering). Harvest seed heads when brown and crumbly, dry further indoors, and extract seeds for next season.
