About Tagetes erecta 'Taishan Orange'

Tagetes erecta 'Taishan Orange' · also called Taishan Orange Marigold, Dwarf African Marigold Orange · flowering

'Taishan Orange' is an exceptionally dwarf, well-branched African marigold bred to hold large double orange blooms on short, sturdy stems with little stretching. Its compact, weather-tolerant habit makes it excellent for bedding, edging and pack sales. Like all African marigolds it thrives in full sun and free-draining soil, flowering freely through summer with deadheading.

Growth habit: Very dwarf, densely branched and self-supporting, carrying large double blooms low on the plant without stretching. Deadheading keeps it flowering continuously.

What fertiliser tagetes erecta 'taishan orange' actually wants — and why

Tagetes erecta 'Taishan Orange' 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 tagetes erecta 'taishan orange': 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 tagetes erecta 'taishan orange', 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 tagetes erecta 'taishan orange':

Apply a balanced feed at planting and a high-potash liquid feed every 2-3 weeks while flowering to fuel the large blooms; keep nitrogen moderate to maintain its naturally compact, sturdy habit. 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 tagetes erecta 'taishan orange' is resting. For the wider context on indoor feeding rhythms across the seasons, the houseplant fertiliser schedule walks through the year month by month.
