Host Plant is a term used for a plant that can support a pest or pathogen.. . Host Plant is most useful when it is tied to the exact plant part, season, cultivar, and growing conditions being described.

In horticulture, Humid-Climate Variety describes a cultivar observed to perform in humid conditions.

Humid-Climate Variety is most useful when paired with accurate labels and source history. In fig collecting, shorthand or naming terms should never replace careful provenance, photos, and grower notes.

In horticulture, Humidity Dome describes a clear cover that holds moisture around young plants. . For Humidity Dome, the practical interpretation depends on the growing setup: container or in-ground tree, drainage, watering pattern, sunlight, season, and local weather.

Humus-rich describes soil containing well-decomposed organic matter. Humus helps improve soil structure, water-holding capacity, nutrient retention, and microbial activity. Figs benefit from healthy soil organic matter, but humus-rich does not mean soggy. Good drainage remains essential, especially in containers and heavy soils where excess water can reduce oxygen around roots.

A hybrid is offspring produced from genetically distinct parents. In horticulture the term may refer to controlled crosses, natural crosses, or seedlings that combine traits from different lines. Named fig cultivars are usually maintained by cuttings or grafting, so they remain clones of a selected plant. Seed-grown figs are genetically variable and may be hybrids if produced from pollen and seed parents with different backgrounds.

IBA stands for indole-3-butyric acid, a rooting hormone used to encourage adventitious root formation on cuttings. It is sold in powders, liquids, and gels at different strengths. Fig cuttings often root without hormone, but IBA can help with difficult material or less-than-ideal conditions. More hormone is not always better; correct concentration, fresh cuttings, moisture balance, and clean media are still crucial.

In horticulture, Identification Confidence describes degree of confidence in a cultivar identification.. . Identification Confidence is most useful when it is tied to the exact plant part, season, cultivar, and growing conditions being described.

Import Permit is a term used for authorization required for some plant imports.. . Import Permit is most useful when it is tied to the exact plant part, season, cultivar, and growing conditions being described.

In-Ground Planting is a term used for growing a fig directly in the ground.. . In-Ground Planting is most useful when it is tied to the exact plant part, season, cultivar, and growing conditions being described.

Indole-3-butyric acid is a synthetic or naturally occurring auxin used in plant propagation to stimulate root initiation. It is one of the common active ingredients in commercial rooting products. When rooting figs, indole-3-butyric acid can be useful but does not compensate for rotten wood, poor sanitation, low oxygen, or excessive moisture. Growers should follow product directions and avoid contaminating the container with used cuttings.

Indoor Overwintering is a term used for holding figs indoors or under shelter during winter.. . Indoor Overwintering is most useful when it is tied to the exact plant part, season, cultivar, and growing conditions being described.

Infection Court refers to the site where a pathogen enters plant tissue.. . Infection Court is most useful when it is tied to the exact plant part, season, cultivar, and growing conditions being described.

Insecticidal Soap is a term used for soap-based spray used against soft-bodied pests. Related glossary ideas include integrated pest management.. . Insecticidal Soap is most useful when it is tied to the exact plant part, season, cultivar, and growing conditions being described.

Insectiferous means bearing or containing insects. In fig terminology it is most often associated with caprifigs or fig structures that contain fig wasps or wasp life stages. The term matters because fig pollination depends on a specialized relationship between figs and fig wasps. In edible fig culture, whether insect-bearing caprifigs are present can determine whether pollination-dependent crops are retained or drop.

Integrated pest management, or IPM, is a decision-making approach that combines monitoring, correct identification, prevention, cultural practices, biological control, and targeted treatments when needed.

For figs, IPM means looking at the whole growing system before spraying or treating by habit. Sanitation, watering practices, pruning, pest exclusion, beneficial organisms, and careful diagnosis can prevent many problems or reduce the need for stronger controls.

Intercropping is the practice of growing two or more crops in the same space during part or all of their production cycles. It can be used to improve land use, soil cover, biodiversity, or harvest diversity. In fig plantings, intercropping may involve herbs, cover crops, annual vegetables, or low-growing plants near young trees. Competition for water, nutrients, light, and root space must be managed so companion plants do not reduce fig growth or fruiting.
