Fig Leaves Turning Yellow? Check These 4 Causes To Get Figs Back to Health

Fig leaves turning yellow? It happens, but it doesn’t just happen for no reason. Those deeply lobed green leaves losing their luster and switching to a sickly yellow are the plant’s way of sending you an SOS. And basically, it’s the plant telling you that it is under stress. Sometimes the cause is obvious and immediate, like a recent environmental trigger. Other times, the issue is lurking beneath the soil line and harder to judge.

Luckily, the fig is surprisingly communicative. Because they are adapted to specific drainage and light conditions, they react quickly when those conditions shift. For example, when growing figs, they are sensitive to wet feet, and require excellent drainage to thrive. When the soil stays saturated, oxygen is pushed out, roots begin to die, and that lush green canopy begins to fade from vibrant emerald to cream.

It’s important to honor their native preferences as much as you can – and when you deviate, make adjustments quickly. Figs like the steady, deep moisture of a mountain slope, not the stagnant water of a bog. Of course, there can be other reasons for a sudden color chance. But fig tree leaves turning yellow doesn’t have to be a death sentence. The trick is figuring out what is stressing your plant out before the tree starts dropping leaves. Here’s your roadmap back to healthy, happy and fruitful figs.

1. Water Stress: Too Much or Too Little

Figs evolved in regions where the soil is often rocky and drains rapidly, while rain only shows up sporadically. To survive, their root systems grow wide and relatively shallow to catch every drop. In a home garden or a patio container, this shallow root system makes them touchy about both overwatering and prolonged drought.

Too much water is the most frequent killer of container-grown figs. When roots sit in saturated soil, they effectively suffocate. Once root rot sets in, the vascular system of the tree breaks down. The roots can no longer pull up nutrients, even though they are surrounded by water. In this case, leaves go yellow from starvation and lack of oxygen. You’ll notice the soil feels heavy, and the yellowing may be accompanied by a limp, mushy texture to the foliage.

Conversely, underwatering creates a different kind of yellowing. As the tree tries to conserve moisture, it will sacrifice older leaves. The soil will often shrink away from the edges of the pot, and the leaves will wilt and turn brittle before or during the yellowing process. Both create fig tree yellow leaves – but need opposite fixes. The best tool is your own hand. Stick a finger 2-3 (5-8 cm) inches into the soil. Container figs need water the moment it feels dry at that depth. For in-ground trees, check a bit deeper, at about six inches (15 cm). The goal is moist but never soggy.

If you suspect overwatering, stop immediately. Allow the soil to dry out before adding another drop. Ensure your pots have ample drainage holes, and empty saucers after watering so figs aren’t sitting in puddles. If your soil stays wet for more than 3 days, the media is likely too heavy. Consider repotting with a high-drainage mix containing perlite and pine bark. If you struggle to gauge moisture, a soil meter like the Yamron Soil Moisture Meter from Amazon removes the guesswork, and is especially useful for large planters where the bottom stays wetter than the top.

2. Nitrogen Deficiency

If you notice that the yellowing starts strictly on the older, lower leaves while the new growth at the tips remains green, you are likely looking at a nitrogen deficiency. Nitrogen moves around in plants. When supplies drop, the plant steals nitrogen from old leaves to feed new growth. Old leaves turn yellow and fall while new growth stays greenish. This results in a progressive yellowing from the bottom up.

While figs aren't as hungry as heavy feeders like tomatoes, they do require consistent nutrition to maintain their large leaf surface area. This is especially true for container figs, as the frequent watering required for pot-based growing tends to leach nutrients out of the bottom of the container over time. Nitrogen shortage shows up most in spring when trees are growing quickly but haven't been fed in a while.

To remedy a deficiency, use a balanced, slow-release fertilizer such as GardenWise 10-10-10 Slow-Release All Purpose Feed for Figs, available from Amazon. A 10-10-10 or 8-8-8 ratio is ideal for a steady nitrogen boost without overstimulating it. Apply when new growth starts in spring, then again midsummer. It is important to note that yellow leaves will not turn green again; they have been tapped out by the plant. The goal of fertilizing is to ensure the next flush is a healthy deep green.

Be wary of over-fertilizing, however. Excessive nitrogen can lead to burned leaves and leggy growth, and can inhibit fruit production, making the tree focus on leaves rather than figs. For a really long-term approach, try top-dressing with aged compost or well-rotted manure in the spring. This provides a gentle, multi-nutrient boost.

3. Transplant Shock

If you’ve moved your plant, whether from a pot to the ground, or to a larger container, then it is going to experience some level of stress – hence yellowing figs. This transplant shock can also cause leaf drop. This is often caused by root disturbance or a sudden change in microclimates.

Container figs are sensitive to temperature swings. If a tree has been living in a cozy, humid greenhouse and is suddenly placed in a breezy garden where nighttime temperatures dip below 50°F (10°C) when it is in active growth, then it will also react by yellowing its leaves. Temperature stress plus root disturbance hits figs pretty hard.

While you can’t always prevent shock entirely, you can minimize it. When transplanting, try to keep the root ball as intact as possible. Water deeply both before and immediately after the move to help settle the soil around the roots and eliminate air pockets. Using a product like Superthrive All-Purpose Liquid Food from Lowe’s during transplanting can provide a boost of vitamins and hormones that help the roots re-establish more quickly. A good mulch can also protect roots and minimize environmental shifts.

Be patient, and give your fig tree a few weeks to settle in. Avoid the temptation to fix the yellowing with heavy fertilizer straight off the bat, as this might stress the struggling roots even more. Stick to a consistent watering schedule (moist, not soggy) and wait for the tree to push out new green growth. Yellow leaves may drop, but healthy new leaves should follow once roots get reestablished.

4. Pest Problems

While figs are generally hardy, they are not invincible. Sap-sucking pests like scale, spider mites, and mealybugs can weaken a stressed tree to the point of discoloration. These pests act like tiny vampires and all feed on sap, draining the life-force from the leaves, which causes localized yellow spotting or a faded look.

Check the undersides of the leaves and the axils (the joints where the leaf stem meets the branch). Scale looks like small, waxy brown bumps that can be scraped off with a fingernail. Spider mites are nearly invisible, but you will notice fine, silken webbing between the lobes of the leaves and a stippled yellow appearance on the leaf surface. Where you see white fuzzy stuff, this could indicate mealybugs.

For most common fig pests, a biological approach is best. Use an organic spray like insecticidal soap or neem, such as Bonide Captain Jack’s Ready-to-Use Neem Oil from Amazon. It coats the pests and disrupts their life cycle without leaving harsh residues. Be sure to spray the undersides of the leaves thoroughly, as that is where mites and mealybugs love to hide, and repeat weekly for 3 weeks. For heavy scale infestations, use a soft brush to physically remove the insects before treating the area with neem oil or an insecticidal soap. Keep your tree well-hydrated, as spider mites target drought-stressed plants.

A few yellow leaves at the bottom of the tree in the heat of summer aren't a crisis. Figs drop some older leaves naturally. However, if half the canopy is turning pale, it is time to intervene. Left unchecked, chronic yellowing leads to stunted growth and a significant reduction in your fig harvest.

Luckily, figs are resilient and should bounce back once you address what is stressing them. Whether it’s a drainage issue or a nitrogen gap, take steps to rectify things now, and the tree should bounce back in a growing season. Focus on the new growth. If the new leaves are coming in strong, green and vibrant, you’ve successfully navigated the crisis.

Fig Care Essentials

Figs aren't overly demanding, but if you want to protect them from the anxiety and stress of yellow leafing, this trio of products are essential for ongoing plant health and eventual fruiting. If you have very acidic soil, your fig might benefit from a dusting of garden lime, such as Espoma Organic Garden Lime from Lowe’s. Figs prefer a slightly alkaline to neutral pH (6-7.5), which reflects native growing conditions, to process nutrients efficiently. Check soil pH before adding amendments.
