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.

In horticulture, Downy Mildew describes a moisture-favored disease group with fuzzy growth on leaves.. . Downy Mildew is most useful when it is tied to the exact plant part, season, cultivar, and growing conditions being described.

Drainage Hole refers to an opening that lets excess water leave a container. . For Drainage Hole, the practical interpretation depends on the growing setup: container or in-ground tree, drainage, watering pattern, sunlight, season, and local weather.

Dried Fruit Beetle is a term used for a beetle associated with dried or overripe fruit. Related glossary ideas include integrated pest management. . When describing Dried Fruit Beetle, 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.

Drip irrigation delivers water slowly near the root zone through emitters, tubing, or drip lines. It reduces water waste compared with overhead watering and can keep foliage drier, which is helpful in humid or disease-prone conditions. For figs, drip irrigation is useful in orchards, containers, and dry climates when managed correctly. The goal is consistent moisture without waterlogging. Emitter placement, soil texture, mulch, container size, and seasonal demand all influence how long and how often drip systems should run.
