If by pine cone ginger you are referring to Zingiber Zerumbet, then they do best in medium sun, acidic soil, and like a balanced fertilizer. I fertilize mine with a water soluble 20-20-20 twice a month but also top dress with Osmocote 14-14-14. They won't bloom until the root and rhizome mass gets enough energy. I grow a lot of different gingers, and this particular ginger took 3 years to reach bloom size, but it was worth it. The same would apply to any heliconia. Both are heavy feeders during warm months.

We call these Beehive Ginger. They like a rich soil and plenty of water. Probably why they're growing so well near the septic.

Thanx so much for the quick response and information.
