About Tulipa 'Black Parrot'

Tulipa 'Black Parrot' · also called Black Parrot tulip, dark parrot tulip · flowering

'Black Parrot' is a dramatic parrot tulip with deeply fringed, twisted petals in a near-black, glossy maroon-purple, opening in late spring. A spring-flowering bulb prized for moody borders and cut arrangements, it wants full sun, sharply drained soil, and a cold winter to set its sculptural, feathered blooms on strong stems.

Growth habit: Herbaceous spring bulb bearing grey-green strap-like leaves and one large, fringed, feather-edged flower per stem. Like most parrot tulips it perennialises unreliably and is often grown as an annual or biennial for a guaranteed dark-flowered display.

What fertiliser tulipa 'black parrot' actually wants — and why

Tulipa 'Black Parrot' feeds for next year, not this one — the critical window is after flowering, while the leaves are still green and recharging the bulb.

A low-nitrogen, potassium- and phosphorus-leaning bulb fertiliser (something like 5-10-10) or bonemeal at planting. High nitrogen grows floppy leaves and rots stored bulbs.

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 tulipa 'black parrot': 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 tulipa 'black parrot', 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 tulipa 'black parrot':

Mix bonemeal or a balanced bulb fertiliser into the planting hole in autumn. Apply a high-potash feed as shoots appear and after flowering to fatten the bulb for next year. Skip high-nitrogen feeds, which soften growth and invite rot. The rhythm: a bulb feed at planting, a light feed as leaves emerge, and — most important — a potassium feed straight after flowering while the foliage is still green and feeding the bulb. Never cut the leaves off early.

The dormant-season rule matters more than the exact interval: skip feeding entirely when tulipa 'black parrot' 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 tulipa 'black parrot'

Use the bulb-feed label rate for tulipa 'black parrot'; the timing (post-bloom, leaves still green) does far more for next year's display than the concentration.

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

Signs you are over-feeding tulipa 'black parrot'

Over-feeding is far more common — and more damaging — than under-feeding for most plants. The classic tells for tulipa 'black parrot':

Tall, floppy, soft leaves that flop over (too much nitrogen).
Soft or rotting bulbs lifted at the end of the season.
Lush foliage but few or poor flowers.

Signs you are under-feeding tulipa 'black parrot'

Progressively fewer or smaller flowers year on year ("going blind").
Small, weak bulbs and thin foliage.
Bulbs that fail to come back at all after a few seasons.

Flushing and leaching the salts

Bulbs are not container-flushed like houseplants; the equivalent is not over-feeding and lifting/dividing congested clumps of tulipa 'black parrot' every few years so they are not competing for nutrients.

Organic vs synthetic feeds for tulipa 'black parrot'

Organic options

Bonemeal worked in at planting plus a mulch of garden compost or well-rotted leaf-mould is the traditional, reliable approach for tulipa 'black parrot'. UK: blood, fish & bone or Westland Bulb Food; US: Espoma Bulb-tone or bonemeal.

Synthetic / liquid feeds

A proprietary bulb fertiliser at planting and a high-potash liquid (tomato feed) after flowering — UK: Westland Bulb Food then Tomorite; US: Miracle-Gro Shake 'n Feed Bulb or a bloom booster post-flower.

Brand names are examples, not endorsements, and UK and US ranges differ — check the label’s own NPK and dilution rate, since formulations change.
