Celosia - Fresh Look Orange
Can anyone tell me the preferred soil type for planting my Fresh look Orange Celosia? I planted 2 of them in normal multi purpose compost, 1 is doing ok, although not growing particularly fast. The other is dying, the upright branches have all dropped and the flower heads are wilting. Any ideas?? Had a look online and it said they may prefer slightly acidic soil so should I plant them in erinacous soil??
