How it usually goes wrong

Brown tips on the newest leaves first

A yellow halo sits just inside the brown edge on the pomegranate, and new leaves often come in already tipped with brown during the heating season.

Dry air takes water from the leaf surface continuously, and the tissue at the edge is last in the queue for what the roots send up. Penn State Extension notes there is no single humidity figure that suits every indoor plant. That applies while it is grown indoors; its RHS rating of H3 describes a plant that also grows outside, where the air is seldom that dry.

Telling it apart: Whether the soil is dry too. Crisp edges with damp soil point at the air; with dry soil, at the watering.

Faded, yellow-white areas on the sunny side of the canopy

Scorched leaves on the pomegranate turn from pale to brown and brittle, and the damage stops where the shade of another leaf fell across it.

Even a plant described as full sun can take more through glass than it would outdoors, because glass removes the breeze that carried the heat away.

Telling it apart: Which side. Damage confined to the lit side is light; damage spread evenly is not.

The canopy deflates, and lifts again within hours of a soak

The pomegranate hangs evenly all over, and the compost has gone pale and hard. Nothing is spotted or rotten; the plant is simply short of water.

Its source describes well-drained soil. Below that the cells lose pressure, and pressure is what holds a leaf out straight.

Telling it apart: Water it and look the same evening. A thirsty plant firms up fast; one that does not has a root problem instead.

RHSDiagnose drooping on this Pomegranate
Torn or browned leaves on one side after windy weather

Marks on the pomegranate are concentrated on the windward side: torn edges, dry brown patches and leaves rubbed against each other.

A plant listed for a sheltered site by its source is not built for sustained wind, which both dries its leaves and damages them physically.

Telling it apart: Which side. Wind marks the side facing it; dry soil marks the whole plant.

About the plant

The pomegranate is a fruit-bearing, deciduous shrub in the family Lythraceae, subfamily Punicoideae, that grows to between 1.5–5 metres (5–16 ft) tall. Rich in symbolic and mythological associations in many cultures, it originated in the region spanning the Caucasus and the Iranian plateau — including modern-day Iran, Turkmenistan, Afghanistan and Pakistan. Pomegranate was first domesticated by ancient Iranians in the Iranian plateau and nearby regions about 5,000 years ago. It is extensively cultivated for its fruit.

Uses

What sources record people using this plant for. A traditional or medicinal use listed here is a record of use, not advice to eat it or treat anything with it.

It was once used medicinally for circulatory disorders, and Native Americans made jewelry with the flowers. The seed juice is high in potassium, vitamin C and other antioxidants. Pick a fruit that feels heavy for its size and has no cracks or splits. Pomegranates are picked by hand when fully ripe. Keep whole fruit a few days at room temperature, or store it in plastic bags in the fridge for up to 3 months. The arils can be refrigerated, or frozen spread in one layer and then bagged in the freezer for a later snack. Grenadine, a red syrup for flavoring drinks, is made from pomegranate seeds.

What this does not cover

The figures above are what published sources say, not measurements of the plant in your room. They say nothing about your pot size, your water, the season, or how far from the glass the plant stands, and those decide more than any figure here does.

Humidity has no species figure because no source read for this site publishes one, and the only temperature published for this plant is a cold floor. The simulator fills those gaps with general figures for its kind of plant, marked as general and listed on how we read sources. Where a toxicity row says the plant was not assessed, that is the absence of a finding and not a finding of safety.

If something is already wrong, the diagnosis tool asks about the soil, the window and the watering, which is where the answer usually is.
