Green Grass Grove
Connecting specimen records, habitat data, and the living archive.
Kale / Scarlet
Brassica oleracea var. sabellicaKale / Scarlet is preserved as a distinct red-purple curled kale for nursery, accession, crop, harvest, scouting, and public-education records.
Botanical Overview
Kale / Scarlet is preserved as a distinct red-purple curled kale for nursery, accession, crop, harvest, scouting, and public-education records.
Why We Feature This Specimen
Kale / Scarlet turns colored-kale bed into a measurable Green Grass Grove record connecting identity, North Florida performance, harvest quality, and preservation.
Climate & Protection
Cold protection trigger: Begin cold protection below 40 °F. The cold-damage threshold is the lower temperature where injury becomes likely, not the recommended waiting point.
Sun / Light: Full sun, with light afternoon shade only where summer heat would otherwise reduce crop quality.
Grow as a cool-season crop from fall through early spring; heat shortens quality and wet foliage increases disease.
Planting & Seasonal Guide
Starting & Germination Methods
Seed Sowing
Seed sowing is the umbrella operational method for placing botanical seed into a germination environment. It includes selection of containers or beds, medium, depth, spacing, moisture, temperature, light,…
Open Full Method ↗Indoor Seed Starting
Indoor seed starting produces transplants in containers under managed temperature, light, moisture, sanitation, and spacing before outdoor or greenhouse establishment. It extends the production season, protects valuable seed,…
Open Full Method ↗Direct Seed
Direct Seed is retained as a legacy identity for placing seed directly into its final production container, bed, plug position, restoration cell, or growing location without first raising…
Open Full Method ↗Use the verified seasonal window for this crop and harden or acclimate transplants before exposure.
Plant in the crop-appropriate North Florida window, avoiding predictable frost, extreme heat, or saturated storm periods.
Spacing: Provide at least the room implied by the mature width (18–24 in) plus necessary airflow and harvest access.
Planting Depth: Sow or set at crop-appropriate depth; keep crowns, corms, root flares, and graft unions correctly positioned.
Pollination: Pollination is usually not needed for leaf harvests. Let selected plants flower only for seed saving, beneficial insects, or pollinator support.
Water, Soil & Nutrition
💧 Water & Moisture
Maintain even soil moisture without standing water. Water early at the root zone and avoid drought checks that cause bitterness, tipburn, or premature bolting.
Consistent moisture appropriate to the crop and growth stage.
Use airflow, morning irrigation, sanitation, and crop-specific spacing to reduce humid-season disease.
↘ Drainage & Root-Zone Behavior
✦ Nutrition & Deficiency Checks
Use soil-test-based balanced fertility with split nitrogen on sandy soil. Avoid excessive nitrogen that produces soft growth or raises nitrate and disease risk.
Check pH, roots, moisture, nematodes, disease, and crop stage before diagnosing a nutrient shortage.
Growth, Maintenance & Harvest
Maintenance & Pruning
Use only crop-appropriate pinching, trellising, desuckering, leaf removal, or cleanup with sanitized tools.
Harvest or Observation
Harvest the cultivar-specific edible structure at peak quality and cool promptly.
Storage & Preservation
Cool fresh produce promptly or dry seed and grain to safe storage moisture. Preserve named cultivars through biologically correct seed, clone, graft, or accession methods.
Harvestable Plant Parts & Uses
Harvest the cultivar-specific edible structure at peak quality and cool promptly.
Propagation, Cloning & Tissue Culture
Propagation Methods
Direct Sowing
Direct sowing is the establishment of plants by sowing seed outdoors or into the final production bed rather than transplanting nursery-grown seedlings. It is a complete site operation…
Open Full Method ↗Seed
Seed is retained as an umbrella propagation identity for sexual reproduction through mature botanical seed. A seed normally contains an embryo, stored reserves or nutritive tissue, and protective…
Open Full Method ↗Transplant
Transplant is a nursery handling process that moves an established seedling, rooted cutting, division, grafted plant, or tissue-culture plantlet from one container or site to another. It is…
Open Full Method ↗Aquaponics, Hydroponics & Aeroponics
Aquaponics
Use only with adequate root oxygen, crop-specific mineral supplementation, pest exclusion, and food-safety controls.
Hydroponics
- Target pH5.8–6.5
- Target EC1.5–2.5 mS/cm
Use only where root support, crop duration, sanitation, and nutrient monitoring are appropriate; universal N-P-K formulas are omitted.
Aeroponics
No profile-specific operating notes have been recorded.
Pests, Diseases, Safety & Toxicology
Scout Kale / Scarlet for aphids, flea beetles, caterpillars, leaf miners, slugs, snails, cutworms, and root-feeding pests. Use exclusion and selective controls that protect beneficial insects.
Monitor Kale / Scarlet for damping-off, downy mildew, bacterial or fungal leaf spots, soft rot, and root disease. Use clean seed or transplants, crop rotation, airflow, and root-zone irrigation.
Grow Kale / Scarlet in the cool season, thin for airflow, maintain uninterrupted growth, harvest at the intended baby-leaf or mature stage, and remove bolted or diseased residue promptly.
Kale / Scarlet is most likely to fail from crop-specific timing errors, poor drainage, unverified identity, climate stress, or missed scouting.
Wash carefully, inspect folds or heads for caterpillars, and avoid excessive nitrogen.
Wash carefully, inspect folds or heads for caterpillars, and avoid excessive nitrogen. Follow pesticide labels, preharvest intervals, sanitation, and allergen or medication cautions.
