Gunnera manicata Germination:
"Gunnera seeds are very tiny, with a germination rate of 35-40% in the proper conditions, so plant more than you need, & handle with care"
"Always use gloves when handling seed because the oils from your hands can easily ruin them and prevent germination."
1) Sow in a flat filled with good moistened compost mixed with vermiculite or perlite. Seeds should be lightly strewn at about one inch apart. Do not completely bury as these seeds "need light for germination" so you can simply lightly tamp them into soil or gently cover with a very thin fine layer of sand.
2) Use a heated propagator under your seed tray & cover the tray with plastic or glass and place where temperatures are 68 to 77 degrees F. at all times. The best Gunnera seed propagation is achieved in warmer temperatures. Bottom heat from the heated propagator will help speed germination.
3) Remove the plastic or glass once every day to allow air into the area and mist to keep moist. "Only use a spray bottle to mist them with." Being Gunnera manicata seeds are so tiny, even lightly watering will displace the seeds, causing them to sink deeper into the soil, which will cause them to rot, so only mist them to keep moist, and not overly wet.
5) As with most all Exotic seeds germination can be erratic so patience will be required for them. Germination can be quite quick for some seeds sprouting within 15 days, while most will take up to 90 days.
