About Anthurium andraeanum 'Orange Hot'

Anthurium andraeanum 'Orange Hot' · also called Orange Hot anthurium · tropical

Anthurium andraeanum 'Orange Hot' is a flamingo-flower cultivar grown for its vivid orange, glossy, heart-shaped spathes that bloom almost year-round above deep green foliage. A compact, easy houseplant, it wants bright indirect light, a chunky well-draining aroid mix, warmth, and steady moisture. Its bright colour makes it a cheerful, long-lasting indoor flowering plant and gift.

Growth habit: Compact, clumping evergreen aroid forming an upright rosette of glossy heart-shaped leaves with bright orange spathes held above on slender stalks.

Watch for — No flowers: Most often too little light or excess nitrogen. Increase bright indirect light and use a higher-phosphorus feed.

What fertiliser anthurium andraeanum 'orange hot' actually wants — and why

Anthurium andraeanum 'Orange Hot' is a hungry evergreen fruiter with specific needs — a dedicated citrus feed, switched between summer and winter formulas, keeps it cropping and green.

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 anthurium andraeanum 'orange hot': 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 anthurium andraeanum 'orange hot', 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 anthurium andraeanum 'orange hot':

Feed every 4-6 weeks in spring and summer with a balanced or higher-phosphorus water-soluble fertiliser at quarter to half strength to sustain flowering. Reduce in winter and flush occasionally to prevent salt build-up that browns leaf tips. In practice: a summer citrus feed regularly (often roughly fortnightly) from spring to autumn, switching to a winter citrus feed at a reduced rate over the colder months — citrus feed year-round, unlike most container plants.

The dormant-season rule matters more than the exact interval: skip feeding entirely when anthurium andraeanum 'orange hot' 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 anthurium andraeanum 'orange hot'

Follow the citrus-feed label rate for anthurium andraeanum 'orange hot' and use the correct seasonal formula. The trace-element content matters as much as the NPK — substituting a general feed is the usual cause of yellowing.

Feeding always goes onto already-damp soil, never dry roots — water anthurium andraeanum 'orange hot' first if the soil is dry, then apply the diluted feed. The companion question is when to water at all, covered in the anthurium andraeanum 'orange hot' watering schedule.

Excess soft leafy growth with poor fruit set from too much nitrogen.
Leaf drop shortly after an over-strong feed.

Signs you are under-feeding anthurium andraeanum 'orange hot'

Yellowing leaves — overall pale, or yellow between green veins (magnesium/iron).
