About Bloody Butcher Corn

Zea mays 'Bloody Butcher' · also called Bloody Butcher corn, red heirloom corn · edible

Bloody Butcher is a tall heirloom dent corn with deep blood-red kernels, grown for cornmeal, roasting ears and ornamental ears. Plants reach 3 m and bear two or more ears each. As a wind-pollinated grass it must be sown in blocks, in full sun, on fertile soil after the soil has warmed.

Growth habit: Tall, single-stemmed annual grass forming tassels at the top and silked ears on the stalk; plant in blocks for wind pollination.

Watch for — Lodging: Tall stalks topple in wind on loose or over-fertilised soil; hill up the bases and shelter the block to keep plants upright.

What fertiliser bloody butcher corn actually wants — and why

Bloody Butcher Corn feeds in two distinct phases — balanced to build the plant, then high-potassium the moment flowering starts to set and fill a heavy crop.

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 bloody butcher corn: 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 bloody butcher corn, 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 bloody butcher corn:

Heavy nitrogen feeder: side-dress with a nitrogen-rich fertiliser when knee-high and again at tasseling. Adequate nitrogen is key to tall stalks and full ears. So: a balanced feed or compost at planting, then a high-potash liquid every 1-2 weeks from first flower through harvest across the main season (spring through early autumn).

The dormant-season rule matters more than the exact interval: skip feeding entirely when bloody butcher corn 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 bloody butcher corn

Follow the crop-feed label rate for bloody butcher corn — these are calibrated for hungry vegetables. Consistency through fruiting matters more than strength; erratic feeding causes problems like blossom-end rot.

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

Signs you are over-feeding bloody butcher corn

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

Vigorous dark-green leafy growth but few flowers or fruit (excess nitrogen).
Lush foliage hiding the crop; soft growth prone to pests and disease.
Salt crust on the soil and scorched leaf edges in containers.

Signs you are under-feeding bloody butcher corn

Pale, yellowing lower leaves and stunted growth.
Small fruit, poor set, and a quickly exhausted plant.
Blossom-end rot and weak cropping from erratic or insufficient feeding.

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

Flushing and leaching the salts

In containers, fertiliser salts build up fast — water bloody butcher corn thoroughly so excess drains from the base each time, and flush pots with plain water every few weeks to prevent a damaging salt build-up.

Organic vs synthetic feeds for bloody butcher corn

Organic options

Garden compost or well-rotted manure dug in before planting, plus a liquid comfrey or seaweed feed once fruiting starts. UK: comfrey feed or organic Tomorite; US: Espoma Tomato-tone or Neptune's Harvest. Builds soil and feeds in one.

Synthetic / liquid feeds

A balanced feed at planting then a high-potash tomato feed in fruiting — UK: Growmore at planting then Tomorite (Levington) or Phostrogen; US: a balanced 10-10-10 then Miracle-Gro Tomato or a bloom booster.

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

Fertilising bloody butcher corn — frequently asked questions

What fertiliser does bloody butcher corn need?

Balanced (even N-P-K) at planting for roots and frame, then switch to a high-potassium ("high-potash") tomato-style feed once the first flowers open — potassium is what sizes and ripens fruit, not nitrogen. Bloody Butcher Corn feeds in two distinct phases — balanced to build the plant, then high-potassium the moment flowering starts to set and fill a heavy crop.

How often should I feed bloody butcher corn?

Heavy nitrogen feeder: side-dress with a nitrogen-rich fertiliser when knee-high and again at tasseling. Adequate nitrogen is key to tall stalks and full ears.

What strength of feed for bloody butcher corn?

What does over-feeding bloody butcher corn look like?

Vigorous dark-green leafy growth but few flowers or fruit (excess nitrogen). Lush foliage hiding the crop; soft growth prone to pests and disease. Salt crust on the soil and scorched leaf edges in containers. Staying on a high-nitrogen feed once bloody butcher corn starts flowering is the classic error — you get a huge leafy plant and a disappointing crop. Switch to high-potash the moment flowers appear.
