Damping off is a potential problem and general nursery precautions to lessen this threat should be in place; I use appropriate contact anti-fungal sprays preventatively. Studies on other plants indicate that a low concentration of a smoke water spray has a lowering of the Pythium impact. There is a measure of protection afforded by the cotyledon while it is...
The cotyledons provide nutrients up to a certain stage of development and then none at all. To try and establish which additives were most effective to promote growth, I used Protea mundi, P. coronata, P. scolymacephela, Leucadendron salicifolium and L.lauroleum These species were selected due to availability, ease of sorting, quick germination and I have...
Potting soil can be a limiting factor to good growth of plants and various mixes have been tried for the seedling stage. Any mix with salt in it should be avoided and I have had sub-optimal results using unwashed coco fibre, regardless of what it has been mixed with. Better results were obtained when using peatmoss (sphagnum moss) mixed with matured small pine...
