It sounds like you're on an exciting journey with your indoor plant collection! Calla lilies are indeed beautiful and can add a touch of elegance to any indoor space. Let me share a bit more based on what I've experienced and read:
Ideal Conditions: Calla lilies do well in bright, indirect light. If you don't have a suitable window, a grow light could help mimic those conditions. They enjoy consistent temperatures without drafts—it’s all about keeping them cozy.
Watering and Soil: I've found that using a pot with good drainage is crucial to avoid root rot. When it comes to soil, a mix that’s rich in organic material works best. Peat moss and perlite mixed into the soil can improve drainage and aeration. Watering is about balance—keeping the soil moist but not soggy. I usually poke my finger into the soil to see if the top inch is dry before watering again.
Pests and Diseases: Regularly checking the undersides of leaves can help catch any pests early. Neem oil can be a natural option to manage aphids or mites without harming the plant.
Blooming: Bloom time can vary, but they often reward good care with vibrant blooms. The occasional use of a phosphorus-heavy fertilizer can enhance blooms. After they bloom, let them rest before gradually resuming regular care.
Propagation: Dividing rhizomes after the leaves have died back can be a satisfying way to promote new growth. Just ensure each divided piece has a visible eye or growth point.
Growing calla lilies indoors means observing their unique needs and rhythms, but the payoff is seeing those magnificent flowers. What attracted you to calla lilies in the first place?
