In horticulture, Soil Amendment describes material added to improve soil properties. . For Soil Amendment, the practical interpretation depends on the growing setup: container or in-ground tree, drainage, watering pattern, sunlight, season, and local weather.

Soil microbial activity is the work of bacteria, fungi, and other microscopic organisms in decomposing organic matter, cycling nutrients, building soil structure, and interacting with roots. For figs, active soil biology can support healthy roots, especially in mulched in-ground plantings. Good drainage, organic matter, and avoiding unnecessary soil disturbance generally support microbial life better than relying on any single additive.

Soil pH measures the acidity or alkalinity of soil. It affects nutrient availability, microbial activity, and root function.

Figs tolerate a moderate range of soil pH, but extremes can cause nutrient problems or weak growth. If leaves show chlorosis or growth is poor, pH should be considered along with drainage, roots, watering, and fertility.

Soluble Fertilizer refers to fertilizer dissolved in water before application. . For Soluble Fertilizer, the practical interpretation depends on the growing setup: container or in-ground tree, drainage, watering pattern, sunlight, season, and local weather.

Soluble Solids refers to dissolved sugars and other compounds in fruit juice.. . Soluble Solids is most useful when it is tied to the exact plant part, season, cultivar, and growing conditions being described.

Sooty Mold is a term used for dark fungal growth on honeydew-coated surfaces. Related glossary ideas include integrated pest management.. . Sooty Mold is most useful when it is tied to the exact plant part, season, cultivar, and growing conditions being described.

Sorting Fruit is a term used for separating fruit by condition, size, or ripeness.. . When describing Sorting Fruit, 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.

Sour Rot refers to decay associated with souring and microbial activity. Sour Rot 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.

Source Leaf means a leaf producing more sugars than it uses in practical plant language. Source Leaf 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.

In horticulture, Source Reliability describes confidence in the source of plant material.. . Source Reliability is most useful when it is tied to the exact plant part, season, cultivar, and growing conditions being described.

Source Tree refers to the tree from which material was taken.. . Source Tree is most useful when it is tied to the exact plant part, season, cultivar, and growing conditions being described.

In horticulture, Souring describes spoilage of fruit involving microbes and fermentation.. . Souring is most useful when it is tied to the exact plant part, season, cultivar, and growing conditions being described.

South-Facing Wall refers to a wall exposure that can collect extra sun and warmth.. . South-Facing Wall is most useful when it is tied to the exact plant part, season, cultivar, and growing conditions being described.

Spaghnum Peat Moss appears to be a misspelled entry for sphagnum peat moss, a moisture-retentive organic material used in potting and propagation mixes. The term is left with its existing spelling here so existing links or records are not broken. In fig rooting, sphagnum peat moss can hold moisture around cuttings, but it should be balanced with aeration and sanitation. Overly wet peat-heavy media can encourage rot, while dry peat can repel water until properly moistened.

Spider Mite is a term used for a tiny mite that can stipple and weaken leaves. Related glossary ideas include integrated pest management. Spider Mite 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, Sport describes a naturally occurring variant arising from mutation.. . Sport is most useful when it is tied to the exact plant part, season, cultivar, and growing conditions being described.
