Why Are My Fig Leaves Going Brown and Crispy at the Edges?

Brown, papery or crispy leaf margins on a fig tree — where the edges of the leaves turn tan or brown and dry out while the rest of the leaf stays green — are a visible stress signal. This symptom can be caused by several different factors, from water stress to salt damage, and telling them apart is straightforward once you know what to look for. The good news is that scorched leaf edges do not usually indicate a fatal problem, and most of the causes can be corrected quickly.

Sunscorch

When a fig that has been acclimatised to lower light levels — perhaps kept indoors or in a shaded position — is suddenly moved into intense direct sun, the leaves are unable to cope with the sudden radiation intensity and the leaf margins scorch. The damage is permanent on the affected leaves, but new growth that develops in the new position will be properly acclimatised. When moving a container fig to a sunnier position, do so gradually over seven to ten days, increasing sun exposure incrementally.

Wind scorch and desiccation

Exposed fig trees, particularly in coastal gardens or elevated positions, suffer leaf margin browning from desiccating winds. The wind strips moisture from the leaf surface faster than the roots can replace it, causing the margins — the first parts to dry out — to turn brown and crispy. Providing a windbreak on the exposed side, whether a hedge, fence or other barrier, significantly reduces this problem. Container figs should be moved to a sheltered position during periods of strong, drying winds.

Drought stress

A fig tree that has been consistently under-watered — particularly a container fig in hot weather — may develop brown leaf margins as the first visible symptom of water stress before more serious yellowing and leaf drop begins. Check the soil or compost moisture level regularly. For container figs in summer, daily checking and watering may be necessary during hot spells. Water deeply so the entire root ball is moistened, rather than a superficial surface wetting that does not reach the deeper roots.

Fertiliser or salt burn

Applying too concentrated a fertiliser solution — particularly a liquid feed that is too strong or applied when the compost is dry — causes salt damage to the roots, which shows up as brown leaf margins. Always water the plant thoroughly before applying any liquid feed, never apply to dry compost, and follow the dilution instructions on the product exactly. If you suspect salt accumulation in a container, flush the compost through with several litres of plain water.

Cold damage in spring

A late frost or cold wind after the new leaves have opened in spring causes rapid browning at the leaf margins or tips. The damage is cold-injury rather than drought or sun-related. The tree will produce replacement growth from the same buds over the following weeks, and the overall health of the tree is not seriously affected.
