Zone 9 grower has D. regia outside in 10" pot (peat/perlite/sand, 9h sun, distilled water, light Osmocote). Asked about dormancy and winter fertilizing.
CA climate mimics native SA. Plant will have short dormancy Dec–Jan (leaves shrink or die to hibernaculum). Stop fertilizing if growth stops. Likely catches bugs outdoors too. Good resource: CP.org guide.
