About Nymphaea 'Director George T. Moore'

Nymphaea 'Director George T. Moore' · also called Tropical Blue Waterlily · flowering

Nymphaea 'Director George T. Moore' is a celebrated tropical day-blooming waterlily with intense deep violet-blue flowers and a bright golden centre, held above the water on tall stalks. Heat-loving and floriferous, it is grown as a summer or glasshouse pond plant in the US and UK and must be overwintered frost-free.

Growth habit: Vigorous tropical day-blooming waterlily with rounded floating leaves, often purple-flecked when young, and large violet-blue flowers held well above the water on stiff stalks. Free and continuous in warmth.

Watch for — Weak flower colour or quantity: Shade, cool water or under-feeding dulls the violet-blue and cuts bloom count. Maximise sun and warmth and feed every few weeks through summer.

What fertiliser nymphaea 'director george t. moore' actually wants — and why

Nymphaea 'Director George T. Moore' is an easy, light foliage feeder — a half-strength balanced liquid feed through the growing months keeps it green without forcing weak, sappy growth.

A balanced general houseplant feed (roughly even N-P-K) is exactly right — it is grown for foliage, so steady, moderate nitrogen for healthy leaves is the goal, not a bloom or root formula.

For the language behind the three numbers on the bottle — what nitrogen, phosphorus and potassium each do — see the NPK ratio explained entry. The short version for nymphaea 'director george t. moore': match the feed to the job the plant is doing right now, not to a generic “plant food” on the shelf.

How often to feed nymphaea 'director george t. moore', and which months

Feeding only earns its keep while the plant is in active growth and can use the nutrients — pour feed into a dormant or low-light plant and it simply builds up as root-burning salt. For nymphaea 'director george t. moore':

Feed heavily for continuous tropical bloom: press aquatic fertiliser tablets into the basket every 2-4 weeks throughout the warm season. Taper feeding off as temperatures drop in autumn and stop entirely before lifting for winter storage. Treat that as every 2-4 weeks between spring through early autumn (roughly March to September); ease off in autumn and stop entirely in the low light of winter.

The dormant-season rule matters more than the exact interval: skip feeding entirely when nymphaea 'director george t. moore' is resting. For the wider context on indoor feeding rhythms across the seasons, the houseplant fertiliser schedule walks through the year month by month.

What strength to mix for nymphaea 'director george t. moore'

Half strength is the safe default for nymphaea 'director george t. moore' — houseplant feeds are formulated strong, and the diluted dose is gentler on the roots while still ample for foliage.

Organic options

A diluted seaweed or worm-casting feed, or fish emulsion if you can tolerate the smell indoors. UK: Westland or Baby Bio Organic, dilute seaweed; US: Espoma Indoor! or Neptune's Harvest fish & seaweed. Slow, gentle and hard to overdo.
