The primary propagation methods for todea are through spores, division, or tissue culture. Successful propagation requires attention to humidity, indirect light, and well-draining, acidic soil. Special considerations include maintaining a sterile environment when handling spores or during tissue culture. Propagating todea is moderately difficult due to the slow germination of spores and slow growth. Steps for spore propagation: 1) Collect spores from fertile fronds. 2) Sow spores on a moist, sterile substrate. 3) Cover with a plastic dome to maintain humidity. 4) Keep in indirect light at a temperature of 15-20°C. 5) Transplant young ferns once they've developed true leaves.
