Enable an AI agent to recognise heading cabbage, assess the condition of a plant or harvested head, and choose justified cultivation, harvest, storage or referral actions.
Research draft, second pass
A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description
Enable an AI agent to recognise heading cabbage, assess the condition of a plant or harvested head, and choose justified cultivation, harvest, storage or referral actions.
It can be Identify a plant or head provisionally and request cultivar or diagnostic evidence when morphology is insufficient.; Monitor head formation and flag delayed heading or a transition toward flowering.; Select planting, watering or protection actions using cultivar, stage and local growing guidance.; Assess harvest readiness from head development, firmness, integrity and intended use.; Inspect and route damaged cabbage for diagnosis, prompt use, storage or rejection under applicable criteria.; Track a harvested head through trimming and storage inspections while preserving its connection to the source plant..
Distinguishing features
At the heading stage, verify that the main harvested structure consists of overlapping leaves enclosing a terminal growing point; an immature or damaged plant requires additional identity evidence.
Distinguish a terminal leafy head from the numerous axillary buds harvested as Brussels sprouts and the swollen stem harvested as kohlrabi.
Inspect the harvested structure: cabbage has a leafy head, rather than the enlarged flowering structures associated with broccoli or cauliflower.
Separate heading cabbage from non-heading kale and collards using mature growth habit and cultivar provenance; absence of a head in a seedling is inconclusive.
Do not accept the common name 'cabbage' or head shape alone as proof of this entry: require taxonomic or cultivar evidence to exclude Chinese cabbage and resolve uncertain Savoy assignments.

Characteristics
- Identity evidence
- Specimen linked to cultivar label, supplier record or identification assessment, with confidence Seedlings and damaged plants may not display diagnostic heading features.
- Cultivar and declared head type
- Named cultivar or unknown; rounded, flattened, pointed or unresolved head type Expected shape, maturity and storage behaviour must be interpreted against the cultivar.
- Observed leaf phenotype
- Colour, surface texture and waxiness, with outer or inner leaf position recorded Supports identification and separates expected cultivar appearance from possible injury.
- Developmental stage
- Seedling, establishing, expanding rosette, heading, harvest-ready, bolting, flowering or senescent The same loose leaves or stem elongation have different meanings at different stages.
- Head attachment
- Attached to rooted plant, cut head, or retained stem with regrowth Determines whether further field growth, harvest or postharvest handling is possible.
- Head dimensions
- Maximum diameter and height in cm, with measurement date Tracks heading progress and supports cultivar-specific harvest assessment.
- Head mass
- g or kg, specifying whether wrapper leaves and stalk are included Allows meaningful comparison of harvest output and postharvest mass change.
- Head firmness
- Loose, intermediate or firm, with assessment method Supports readiness assessment but must be interpreted with head type and condition.
- Head integrity
- Intact, superficially cracked, deeply split or mechanically damaged; extent recorded Changes harvest urgency, handling needs and suitability for storage.
- Damage distribution
- Root, stem, growing point, wrapper leaves or inner head; symptom and severity Superficial leaf injury and damage extending into the head require different decisions.
- Root-zone and exposure context
- Linked moisture, temperature, irrigation and transplant observations Provides evidence for interpreting establishment failure, poor heading and splitting.
- Postharvest condition history
- Harvest time, trimming history, temperature in °C, relative humidity in %, and inspection records Supports assessment of wilting, deterioration and remaining suitability for an intended use.

Drafted structure
Bundle to layer to finding to question, as the second pass will find it: 5 bundles · 10 layers · 10 findings · 20 questions.
Heading cabbage identity Establish whether the plant or head belongs to the registered cabbage concept.
Common names, immature appearance and differing horticultural classifications can produce incorrect assignments.
Name and cultivar evidence
Record the basis for assigning a specimen to this entry.
Taxonomic circumscription
Preserve the registry name while recording the naming authority used for identification. The [RHS Capitata Group profile](https://www.rhs.org.uk/plants/139301/brassica-oleracea-capitata-group/details) includes red and Savoy cabbage, but equivalence with this registry variety requires resolution.
- Which authority and cultivar evidence support assigning this specimen to Brassica oleracea var. capitata? provenance
- Does the registry intend this variety to include the full Capitata Group, including Savoy cabbage? boundary
Diagnostic head architecture
Use organ identity and growth habit to distinguish neighbouring crops.
Terminal leafy head
Record whether the observed structure is an enclosing leafy head and whether developmental stage makes that observation diagnostic.
- Is the principal enlarged structure a terminal leafy head, an axillary bud, a swollen stem or a flowering structure? definition
- If the plant has not headed, what evidence distinguishes immature cabbage from a non-heading Brassica or Chinese cabbage? boundary
Head development and reproduction Represent the progression from establishment through heading and possible flowering.
A missing or loose head cannot be judged without developmental stage and cultivar expectations.
Establishment and heading
Track the growing point and formation of enclosing leaves.
Heading progress
Separate a normally developing rosette from stalled heading using dated observations, cultivar expectations and growing-point condition.
- What are the sowing or transplant date, current stage and observed changes in head dimensions and firmness? measurement
- Is the central growing point intact, and what evidence explains absent or uneven head formation? measurement
Reproductive transition
Distinguish heading for food from development toward flowers and seed.
Bolting and crop purpose
Record stem elongation and reproductive structures against the intended outcome for the plant.
- Is the stem elongating through the head or producing visible flower buds? measurement
- Should this plant remain for reproductive development or leave the head-production pathway, given its recorded purpose? action
Growing conditions and heading response Connect cabbage development to root-zone conditions and exposure history.
Agents need evidence for cultivation changes without treating every heading problem as the same deficiency.
Water and root function
Relate moisture history and root condition to establishment and head integrity.
Water status and splitting context
Record moisture changes alongside wilting, growth and head cracking. Heavy rain or irrigation near harvest can contribute to splitting according to [Iowa State Extension](https://yardandgarden.extension.iastate.edu/how-to/growing-cabbage-home-garden).
- What moisture or irrigation changes preceded wilting, renewed head expansion or splitting? provenance
- Does root-zone evidence support a watering adjustment, drainage correction or further root inspection? action
Season and growth constraints
Interpret poor development using cultivar, temperature, spacing and nutrition evidence.
Cultivar and environment fit
Record whether local growing conditions match documented expectations for this cabbage cultivar.
- Which temperature exposures, spacing observations and soil or tissue results could explain the observed heading performance? measurement
- Which local cultivar-specific guidance supports changing cultivation conditions or the planting window? provenance
Cabbage damage and diagnosis Localise injury and distinguish observed symptoms from diagnosed causes.
Wrapper-leaf feeding, growing-point destruction and internal deterioration have different consequences for the head.
Feeding and physical injury
Map damage to cabbage organs and assess whether the head remains protected.
Injury location and extent
Record holes, chewing, frass, cracks and wounds separately from any inferred pest or mechanical cause.
- Is injury limited to wrapper leaves, or does it affect the growing point or penetrate the edible head? measurement
- What observed organism, feeding sign or event supports the proposed cause of injury? provenance
Disorders and deterioration
Assess abnormal tissue and identify when further examination is necessary.
Symptom pattern and diagnostic confidence
Distinguish descriptions such as marginal necrosis, yellowing, root swelling and softened tissue from confirmed physiological or infectious diagnoses.
- Where are abnormal tissues located, how extensive are they, and are symptoms progressing? measurement
- What additional examination or testing is required before choosing treatment, isolation or rejection? action
Harvest and intact-head keeping Support the transition from a growing head to a harvested cabbage with a documented condition history.
Readiness, splitting and subsequent deterioration determine whether a head should remain growing, be harvested or enter storage.
Head readiness and cutting
Assess readiness against cultivar expectations and intended use.
Harvest decision
Combine usable size, firmness and splitting risk instead of relying only on elapsed growing time. [University of Minnesota Extension](https://extension.umn.edu/garden-and-home/yard-and-garden/gardening-in-minnesota/growing-cabbage) describes usable head size and the risk of splitting after maturity.
- Do head size, firmness and integrity meet the documented requirements for this cultivar and intended use? measurement
- Should the head be harvested now, monitored further or referred for condition assessment? action
Postharvest head condition
Track the intact head after cutting, including trimming and storage exposure.
Keeping condition and disposition
Record loss of firmness, wilting, discoloration, wounds and decay against harvest and storage history; appearance alone does not establish food safety.
- What harvest time, trimming, temperature and humidity history accompany the current head condition? provenance
- Under the applicable quality and food-safety criteria, should this head remain in storage, move to prompt use or be rejected? action
What the second pass must settle
- Which taxonomic authority should govern the registry's variety name, and does its intended boundary include Savoy cabbage?
- Which cultivar-specific measurements and observation methods reliably distinguish normal loose heading, delayed maturity and failed head formation?
- Which regional temperature, water and nutrition guidance should support cultivation decisions for each cultivar and planting season?
- What diagnostic evidence is needed to distinguish physiological inner-leaf injury from infectious deterioration without unnecessary destructive inspection?
- Which validated storage conditions, keeping periods and rejection criteria apply to each cultivar, head condition and intended use?
