Dennis Johnson is a name that appears in fig-collecting discussions and provenance notes. In a glossary context, a person entry is most useful when it helps readers understand labels, collection histories, or references encountered in variety descriptions. Because person-related fig history can be difficult to verify from public information, Fig Database should treat such entries cautiously. This entry may need additional human review if a more detailed biography, collection role, or specific cultivar connection is desired.

Dentate Margin means a leaf edge with outward-pointing teeth in practical plant language. Dentate Margin is useful when comparing fig leaves because leaf shape can vary by cultivar, tree age, shoot vigor, and season. Clear leaf descriptions should mention the part being observed and should be paired with photos when the term is used for identification.

DFIC refers to the Davis Fig Indexing Collection, a collection associated with fig germplasm work in California. In variety discussions, DFIC numbers or references may help identify accessions, research material, or historical records connected to fig study and preservation.

For collectors, a DFIC reference is useful provenance information, but it should be handled precisely. A number, accession name, and cultivar name are not always interchangeable without checking the original record and the plant material being discussed.

In horticulture, Dichotomous Branching describes branching in which a growing point divides into two forks.. . For Dichotomous Branching, position on the tree matters: low growth, terminal growth, old wood, and new shoots can lead to different pruning, training, and fruiting decisions.

Dieback is the death of plant tissue, usually beginning at shoot tips, branch ends, or damaged portions of wood. It can be caused by cold injury, drought, root problems, disease, pests, pruning wounds, or general stress. Fig growers commonly see dieback after winter, especially on exposed or marginally hardy trees. Scratching bark to check for green tissue, waiting for delayed budbreak, and pruning back to healthy wood are common ways to assess and manage the damage.

Dieback Line means the boundary between dead and living wood after injury in practical plant language.. . Dieback Line is most useful when it is tied to the exact plant part, season, cultivar, and growing conditions being described.

In horticulture, Dietary Fiber describes plant carbohydrate that contributes to fiber intake.. . Dietary Fiber is most useful when it is tied to the exact plant part, season, cultivar, and growing conditions being described.

Disease Triangle is a term used for the interaction of host, pathogen, and environment. Disease Triangle should be used with specific symptoms, timing, and photos. Accurate diagnosis matters because insect feeding, disease, nutrient stress, water stress, and weather injury can produce superficially similar problems on figs.

In horticulture, Distal End describes the end farthest from the base or point of attachment. For pruning, grafting, and variety notes, Distal End should be recorded with its position on the shoot so the observation can be connected to buds, fruiting sites, dieback, or new growth.

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

In horticulture, Distribution History describes the record of how a plant spread among growers.. . Distribution History is most useful when it is tied to the exact plant part, season, cultivar, and growing conditions being described.

The dormancy cycle is the seasonal pattern in which a plant slows growth, rests through unfavorable conditions, and resumes growth when conditions improve. In deciduous figs, dormancy is tied to shorter days, cooler temperatures, leaf drop, and winter survival.

Understanding dormancy helps growers time pruning, cutting collection, up-potting, and winter protection. A fig that is fully dormant can tolerate handling and cold differently than a tree actively growing with tender leaves and soft shoots.

Dormancy Release means the transition from winter rest toward active growth in practical plant language. . For Dormancy Release, the practical interpretation depends on the growing setup: container or in-ground tree, drainage, watering pattern, sunlight, season, and local weather.

Dormant Bud means a living bud that is not currently growing in practical plant language. For pruning, grafting, and variety notes, Dormant Bud should be recorded with its position on the shoot so the observation can be connected to buds, fruiting sites, dieback, or new growth.

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

Dormant Hardiness refers to cold tolerance while a plant is dormant. . For Dormant Hardiness, the practical interpretation depends on the growing setup: container or in-ground tree, drainage, watering pattern, sunlight, season, and local weather.

Dormant Hardwood Cutting means a cutting taken from mature dormant wood in practical plant language. For pruning, grafting, and variety notes, Dormant Hardwood Cutting should be recorded with its position on the shoot so the observation can be connected to buds, fruiting sites, dieback, or new growth.

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

Dormant Spray means a spray applied while plants are dormant in practical plant language. . For Dormant Spray, pair the word with symptoms, timing, photos, and the affected plant part before deciding on treatment; several fig problems can look similar at first glance.
