Perched Water Table means water held at the bottom of a container after drainage in practical plant language. . For Perched Water Table, the practical interpretation depends on the growing setup: container or in-ground tree, drainage, watering pattern, sunlight, season, and local weather.

Perlite is a lightweight expanded volcanic glass used in potting mixes to improve aeration and drainage. It does not provide meaningful nutrition, but it helps create pore space around roots.

Fig growers often use perlite in rooting and container mixes because cuttings need both moisture and oxygen. Very fine or compacted media can stay too wet, while perlite helps reduce that risk when used appropriately.

Permanent Wilting Point means the point where plants cannot recover from lack of available water in practical plant language.. . Permanent Wilting Point is most useful when it is tied to the exact plant part, season, cultivar, and growing conditions being described.

Persistence Trait means the ability of a fig to retain fruit without pollination in practical plant language.. . Persistence Trait is most useful when it is tied to the exact plant part, season, cultivar, and growing conditions being described.

Persistent describes figs that can hold and ripen fruit without pollination. In practical growing language, persistent figs are often called common figs. This trait is central for growers outside areas where the fig wasp is established. A persistent cultivar can ripen edible fruit without caprification, while nonpersistent Smyrna-type fruit commonly drops if not pollinated.

Persistent Breba refers to breba fruit retained without pollination.. . Persistent Breba is most useful when it is tied to the exact plant part, season, cultivar, and growing conditions being described.

Petiole means the stalk connecting a leaf blade to the stem in practical plant language. Petiole 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.

Petiole Scar refers to the mark remaining after a petiole detaches. Petiole Scar 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.

pH measures how acidic or alkaline a solution or growing medium is. A pH of 7 is neutral, lower values are acidic, and higher values are alkaline. For figs, pH influences nutrient availability and root performance. Figs tolerate a fairly broad range, but very high or very low pH can contribute to nutrient problems such as chlorosis, especially in containers or poorly buffered media.

Phenotype means observable traits of a plant in practical plant language. . For Phenotype, the practical interpretation depends on the growing setup: container or in-ground tree, drainage, watering pattern, sunlight, season, and local weather.

In horticulture, Pheromone Trap describes a trap using scent signals to monitor or capture insects. Related glossary ideas include integrated pest management. . For Pheromone Trap, 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.

Phloem is a term used for the vascular tissue that transports sugars and other compounds. . For Phloem, the practical interpretation depends on the growing setup: container or in-ground tree, drainage, watering pattern, sunlight, season, and local weather.

In horticulture, Photoperiod describes the length of day and night. . For Photoperiod, the practical interpretation depends on the growing setup: container or in-ground tree, drainage, watering pattern, sunlight, season, and local weather.

Photosynthate refers to sugars and related compounds produced by photosynthesis. . For Photosynthate, the practical interpretation depends on the growing setup: container or in-ground tree, drainage, watering pattern, sunlight, season, and local weather.

Photosynthetic efficiency is how effectively a plant converts light energy into chemical energy for growth, maintenance, and fruit production. It is influenced by light, leaf health, temperature, water status, nutrients, and stress.

In figs, healthy leaves are the engine that supports fruit sizing and ripening. Severe leaf loss, chlorosis, mite damage, or poor light can reduce the tree’s ability to develop high-quality fruit.

Phytophthora root rot is a root disease caused by water-mold organisms in the genus Phytophthora. It is favored by saturated soils, poor drainage, and stressed root systems.

Figs dislike waterlogged conditions, so prevention is often more important than rescue. Well-drained soil, containers with adequate holes, careful irrigation, and avoiding chronically wet media help reduce root-rot risk.
