In horticulture, Chill Accumulation describes the buildup of cool exposure during dormancy.. . Chill Accumulation is most useful when it is tied to the exact plant part, season, cultivar, and growing conditions being described.

Chill hours are hours of cool winter temperatures used by many deciduous fruit crops to satisfy dormancy requirements. The exact temperature range and model vary, but the concept describes how winter cold helps buds resume normal growth in spring. Figs generally have lower chill requirements than many temperate fruit trees, yet dormancy still matters. Insufficient winter rest, warm spells, or erratic spring weather can affect budbreak timing, breba survival, and the way a fig tree starts growth after winter.

Chilling Requirement is a term used for the amount of cool exposure needed to complete dormancy.. . Chilling Requirement is most useful when it is tied to the exact plant part, season, cultivar, and growing conditions being described.

In horticulture, Chimera describes a plant with genetically different tissue layers.. . For Chimera, preserve source history, labeling, and supporting photos without turning a shorthand note or one observation into a firm identity claim.

Chip Budding is a term used for a budding method using a small bud chip. For pruning, grafting, and variety notes, Chip Budding should be recorded with its position on the shoot so the observation can be connected to buds, fruiting sites, dieback, or new growth.

For Chip Budding, record where it occurs on the shoot or trunk; that position can affect pruning decisions, regrowth after winter injury, grafting, and fruiting wood.

Chlorophyll is the green pigment plants use to capture light energy for photosynthesis. It is concentrated in chloroplasts and is essential for converting light, carbon dioxide, and water into sugars that support plant growth.

In fig leaves, strong green color usually indicates functioning chlorophyll, though color alone does not diagnose every issue. Pale or yellowing leaves may suggest chlorosis, nutrient imbalance, root stress, water problems, pests, disease, or normal seasonal change depending on the pattern and timing.

Chloroplast means the cellular structure where photosynthesis occurs in practical plant language.. . Chloroplast is most useful when it is tied to the exact plant part, season, cultivar, and growing conditions being described.

Chlorosis is yellowing of plant tissue caused by reduced or uneven chlorophyll. It may appear between leaf veins, across an entire leaf, on older leaves, or on new growth depending on the underlying cause. In figs, chlorosis can be associated with nutrient availability, high soil pH, overwatering, root stress, cold soil, pests, disease, or normal leaf aging. The pattern matters: iron-related chlorosis often appears on newer leaves, while nitrogen deficiency is more likely to show first on older foliage.

Circling Roots means roots growing around the inside of a pot in practical plant language.

Circling Roots is especially relevant to fig propagation. Growers use the term when judging whether plant material is forming healthy roots, joining properly, or staying vigorous enough to become a stable young tree.

Cleft grafting is a plant propagation technique used to join a cutting, known as a scion, from one fig variety (Ficus carica) onto an established plant called the rootstock. The process involves making a vertical split in the cut end of the rootstock and inserting a scion that has been shaped into a tapered wedge. At least one side of the scion's cambium layer must align with the rootstock's cambium to allow the tissues to heal and form a successful graft union. The graft is then secured with grafting tape or another suitable material and protected from drying out while the two sections grow together.

For fig growers and collectors, cleft grafting is a useful method for growing multiple fig varieties on a single tree, preserving desirable cultivars, or changing an established tree to a different variety without starting from scratch. It is commonly performed during dormancy or near the beginning of active growth, depending on local conditions. Successful grafting requires healthy plant material, clean cuts, proper cambium alignment, and protection against moisture loss. Once the graft union heals, the scion develops new shoots and eventually produces fruit characteristic of its original variety, while the rootstock continues to provide the supporting root system.

Clonal Propagation refers to propagation that preserves the genetics of a parent plant.

Clonal Propagation is especially relevant to fig propagation. Growers use the term when judging whether plant material is forming healthy roots, joining properly, or staying vigorous enough to become a stable young tree.

Clone Name means a name used for a clonally propagated selection in practical plant language.. . Clone Name is most useful when it is tied to the exact plant part, season, cultivar, and growing conditions being described.

Closed Eye is a term used for an ostiole that appears tight or sealed.. . When describing Closed Eye, use fruit at a known ripeness stage and note whether it is breba or main crop, since weather, pollination, and harvest timing can change the observation.

In horticulture, Coevolution describes reciprocal evolutionary change between interacting organisms.. . Coevolution is most useful when it is tied to the exact plant part, season, cultivar, and growing conditions being described.

In horticulture, Cold Acclimation describes seasonal development of cold tolerance. . For Cold Acclimation, the practical interpretation depends on the growing setup: container or in-ground tree, drainage, watering pattern, sunlight, season, and local weather.

Common fig refers to a type of Ficus carica that can set and ripen fruit without pollination by the fig wasp. This ability is often called parthenocarpy or persistence, and it is why common figs can be grown successfully in regions where the fig wasp is absent.

Most backyard figs in many non-Mediterranean climates are common figs. The term describes pollination behavior, not fruit color, flavor, or quality. A common fig may be green, black, honey-flavored, berry-flavored, early, late, large, small, excellent, or ordinary depending on the cultivar.
