Daisies thrive in bright light, but the intensity and duration differ between indoor and outdoor settings. Outdoors, daisies prefer full sun, requiring at least 6-8 hours of direct sunlight daily. This promotes robust growth and abundant flowering. Indoors, however, daisies need bright, indirect light, such as near a south-facing window. Without sufficient light, indoor daisies may become leggy and produce fewer blooms. Supplemental grow lights can help mimic outdoor conditions.
Outdoor daisies are hardy and adapt to seasonal temperature fluctuations, typically thriving in USDA zones 4-9. They tolerate cooler nights and warmer days but may struggle in extreme heat without adequate watering. Indoor daisies, on the other hand, require stable temperatures between 60-75°F (15-24°C) and moderate humidity. Dry indoor air, especially in winter, can stress the plant, so occasional misting or a humidity tray is beneficial.
Outdoor daisies are more drought-tolerant once established, needing water only when the top inch of soil is dry. Rainfall often supplements their needs. Indoor daisies require more consistent watering due to limited soil volume and drier air. Overwatering is a common issue indoors, as poor drainage can lead to root rot. Always ensure pots have drainage holes and avoid letting indoor daisies sit in water.
Outdoor daisies grow best in well-draining, slightly acidic to neutral soil enriched with organic matter. They benefit from a balanced, slow-release fertilizer applied in early spring. Indoor daisies need a high-quality potting mix with perlite or sand for drainage. Fertilize indoor plants monthly during the growing season with a diluted liquid fertilizer, as nutrients deplete faster in containers.
Outdoor daisies face pests like aphids, slugs, and powdery mildew, which can be managed with natural predators or organic sprays. Indoor daisies are less exposed to pests but may attract spider mites or fungus gnats due to dry conditions or overwatering. Regularly inspect indoor plants and isolate affected ones to prevent infestations. Proper air circulation and avoiding wet foliage reduce disease risks in both settings.
Outdoor daisies spread vigorously, forming clumps that may need division every 2-3 years to maintain health. Indoors, daisies are confined to pots, limiting their growth. Regular pruning encourages bushiness, and repotting every 1-2 years refreshes the soil. Outdoor plants may self-seed, while indoor daisies rely on manual propagation via cuttings or division.
Outdoor daisies enter dormancy in winter, requiring minimal care except for mulching in colder zones. Indoor daisies may continue growing year-round but often slow down in winter. Reduce watering and fertilization during this period. Both types benefit from deadheading spent flowers to prolong blooming, though outdoor plants naturally shed petals more efficiently.
