For my seeds to break dormancy and sprout successfully, I require very specific conditions. I am a heat-loving plant, so warmth is non-negotiable. The soil temperature must be consistently warm, ideally between 70-85°F (21-29°C). I despise cold, wet feet, which will cause my seeds to rot before they even have a chance. My seeds also need light to germinate. Do not bury me deep! I should be gently pressed onto the surface of a well-draining, sterile seed-starting mix. A fine mist of water will settle me into place without disturbing me. Then, please cover my container with a clear plastic dome or wrap to maintain high humidity around me, trapping the warmth and moisture I crave.
Once you see my tiny green shoots emerge, usually within 7-14 days, my needs change immediately. Remove the plastic cover to allow for air circulation and prevent damping-off, a fungal disease that can wipe out my entire generation. I still need plenty of warmth and bright, direct light. A south-facing windowsill or a grow light positioned close above me is perfect. Without strong light, I will become leggy and weak, stretching desperately for more sun. Water me carefully from below or with a gentle mist, keeping the soil slightly moist but never soggy. My succulent leaves store water, so I am more tolerant of missing a watering than of being overwatered.
Before I can move to my permanent home outdoors, I must be hardened off. This process is crucial. My tender foliage, accustomed to the stable indoor environment, is not prepared for the full intensity of the sun, wind, and fluctuating outdoor temperatures. Over 7-10 days, gradually introduce me to the outdoors. Start by placing me in a sheltered, shady spot for a few hours each day, slowly increasing my exposure to direct sunlight and the elements. This process toughens me up, allowing my stems and leaves to adapt so I won't suffer shock when transplanted.
Choose the sunniest, hottest spot in your garden for me. I thrive in full, blazing sun and well-draining, even poor, sandy or rocky soil. Rich, heavy, water-retentive soil will make me unhappy and can lead to root rot. When all danger of frost has passed and the nights are consistently warm, space me about 6-8 inches apart. Gently loosen my roots and plant me at the same depth I was in my pot. Water me in well to settle the soil around my roots. After that, I am incredibly drought-tolerant. I prefer to dry out completely between waterings. My philosophy is simple: plenty of sun, plenty of heat, and not too much water. In return, I will reward you with a vibrant carpet of colorful, papery blooms that open to greet the sun.
