About Bouquet Dill

Anethum graveolens 'Bouquet' · also called Bouquet Dill, Common Dill · herb

A classic, full-sized open-pollinated dill cultivar prized for its large, flat-topped umbels of tiny yellow flowers and abundant seed production. Reaches 60–90 cm tall with fine, blue-green feathery foliage. Excellent for pickling, dried seed harvest, and cut flowers. Bolts readily in heat, which is desirable for seed and floral use.

Growth habit: Upright, tall annual with hollow stems and feathery pinnate leaves; forms large umbel flower heads

Watch for — Swallowtail butterfly caterpillars: Black swallowtail larvae feed heavily on dill foliage. Many gardeners plant extra dill to share with these pollinators; otherwise, hand-pick caterpillars if yield is a priority.

What fertiliser bouquet dill actually wants — and why

Bouquet Dill is a soft, fast leafy herb that you harvest hard — a modest balanced feed keeps tender growth coming without tipping it into bland or bolting.

A balanced general feed (even N-P-K) at modest strength — enough nitrogen to keep replacing the leaves you pick, but not so much that flavour thins or it bolts to seed.

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 bouquet dill: 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 bouquet dill, 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 bouquet dill:

Apply a balanced, low-nitrogen fertiliser (e.g. 5-10-10) at sowing or transplanting. Excessive nitrogen delays flowering and seed set. A single application at establishment is usually sufficient for the season. In practice: a balanced liquid feed every few weeks through the main growing and harvesting season (spring through early autumn), more often the harder you are picking it.

The dormant-season rule matters more than the exact interval: skip feeding entirely when bouquet dill 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 bouquet dill

Half strength is a sensible default for bouquet dill — enough to fuel regrowth after cutting, gentle enough that the leaves stay aromatic rather than watery.

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

Signs you are over-feeding bouquet dill

Over-feeding is far more common — and more damaging — than under-feeding for most plants. The classic tells for bouquet dill:

Fast, soft, pale growth with diluted, less aromatic flavour.
Early bolting (running to flower) and a bitter edge.
Salt crust and scorched tips on container plants.

Signs you are under-feeding bouquet dill

Pale, slow regrowth after cutting and small leaves.
A tired, stalled plant that cannot keep up with harvesting.
Yellowing older leaves in a long-spent pot.

If the symptoms point at watering, light or roots rather than nutrition, the full bouquet dill care brief covers soil, humidity and the common problems for this species.

Flushing and leaching the salts

Pot-grown bouquet dill builds up feed salts quickly — water until it drains each time and flush the pot with plain water every few weeks, especially on a sunny windowsill.

Organic vs synthetic feeds for bouquet dill

Organic options

A diluted seaweed feed or worm-casting tea keeps soft growth coming without overdoing it. UK: dilute seaweed or Westland; US: Espoma Garden-tone or Neptune's Harvest. Gentle, hard to overdo, flavour-friendly.

Synthetic / liquid feeds

A balanced liquid feed at half strength through harvesting — UK: Phostrogen, Baby Bio or Westland; US: Miracle-Gro all-purpose at half strength. Fast regrowth; just do not overdo the nitrogen.

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