So, Kinglake Victoria, where I assume this video was shot, is considered cool by Australia standards yet this C. cooperi has grown just fine with overstory protection. I'm curious, is C. australis a bit hardier? Because I believe that is the one native to Victoria.

Cyathea australis is regarded as very hardy, they like a little shade however seem to take more sun that others. We grow both at lower elevations than Kinglake, however still cool in winter, but can be hot in summer....

Hi, I have the dwarf version since this year that’s 10y old 😢and the 5/6 fonds all went brown in winter and now it’s approaching summer 1 small fond grew but then it it’s crisped up and a new one coming. The pot is very big but soil is very tight. Is it dying? How often shall I water?

[@johnnyAGardening]

It sounds like it is not happy. It may need repotting if it has been in the same soil for a long time. The soil compacts over time. Just keep the soil moist and water the foliage with a with a spray. How often depends o the climate and the position. Just don't let it dry out and ensure drainage is good.

Unfortunately, these were introduced to Hawaii for garden cultivation about 50 years ago and they've escaped into the wild.

Hawaii must provide the perfect conditions for the spore to grow, even better than the natural habitat. However as far as weeds go they are very attractive.

@@johnnyAGardening There already is a thriving native tree fern in the Hawaiian Islands, but the invasive ones have spread to areas where the native ones aren't found.

@@hebneh Do you mean the species Cibotium menziesii or ' hāpuʻu ʻiʻi ' Interested in learning a little more....

NEVER let it dry to a wilt. the fronds will not recover. The plant will live but will look awful.

[@igvtec]

So it won't grow out in a area with only half shad though the day then??

[@johnnyAGardening]

It could grow in morning sun, however that would depend on the climate....
