Common Name: Maidenhair Tree
Scientific Name: Ginkgo biloba
Plant Family: Ginkgoaceae
Lifecycle: Perennial
Ginkgo biloba is often called a living fossil because it is the sole surviving member of an ancient plant lineage dating back more than 200 million years. Revered for its fan-shaped leaves, brilliant golden autumn color, and remarkable resilience, it remains one of the most distinctive trees a gardener can grow. While growing Ginkgo biloba in Zone 8a is generally considered straightforward, our experience on a Mediterranean homestead has revealed that even legendary survivors can struggle during establishment when drought, exposure, and competition come into play.

Our Ginkgo biloba Application @ Tough Kraut
Our relationship with Ginkgo biloba started long before we planted one on our land in Portugal. During a visit to Chengdu, China, in December 2021, we walked beneath mature Ginkgo trees while their brilliant golden leaves covered the sidewalks like a natural carpet. It was one of those moments that stays with you long after the journey ends.
When we later discovered that Ginkgo trees were available locally, we immediately bought two young plants. Neither survived. Undeterred, we purchased another two. Today, one of those trees remains alive and continues its fight for survival in our food forest.
The surviving Ginkgo was planted in late 2022 among a diverse group of companions including Mimosa (Acacia dealbata), comfrey, butterfly bush, elderberry, and Salvia greggii 'Royal Bumble'. While this area will eventually benefit from a developing canopy, it currently remains one of the most exposed and coldest parts of our property.
What makes this tree particularly fascinating is that it dies back to ground level every winter and produces a completely new shoot each spring. At the time of writing, annual growth reaches only around 15 cm (6 in). Conventional wisdom suggests that Ginkgo biloba should have no difficulty handling our winter temperatures, leading us to suspect that summer drought stress, limited irrigation, and establishment challenges may be playing a much larger role than cold itself.
This year, we introduced a simple pallet shade structure and increased watering frequency in an effort to help the tree break out of its annual cycle of regrowth and dieback. Whether this experiment succeeds remains to be seen, but that uncertainty is precisely why we document our experiences. Sometimes the most valuable lessons come from the plants that struggle rather than the ones that thrive effortlessly.
Step-by-Step Growing Guide
Growing Ginkgo biloba in Zone 8a is usually considered straightforward, but our experience demonstrates that even famously resilient trees can encounter establishment challenges. The troubleshooting and FAQ topics discussed later in this article focus heavily on drought stress, dieback, and slow growth because these have been the primary obstacles we've encountered so far.
1. Choose the Right Site
Select a location with full sun or light afternoon shade. Young Ginkgo trees often benefit from protection against intense summer heat, especially in Mediterranean climates where prolonged drought can stress newly planted specimens.
2. Prepare the Soil
Ginkgo tolerates a wide range of soil conditions but performs best in well-drained soil. Incorporate compost if organic matter is lacking, and avoid areas that remain waterlogged during winter.
3. Plant the Tree
Dig a planting hole twice as wide as the root ball and position the tree at the same depth it was growing in its container. Water thoroughly after planting and apply mulch around the root zone while keeping it away from the trunk.
4. Water Consistently
Water deeply during the first several growing seasons, particularly during summer drought periods. While mature Ginkgo trees are drought-tolerant, young specimens require consistent moisture to establish strong root systems.
5. Ensure Proper Pollination
Pollination is only relevant if seed production is desired. Male and female trees are required for viable seed production, although many gardeners intentionally select male trees to avoid the odor associated with fallen female fruits.
6. Prune Annually
Minimal pruning is needed. Remove damaged, crossing, or poorly positioned branches during dormancy while preserving the tree's natural structure.
7. Manage Pests and Diseases
One of Ginkgo's greatest strengths is its resistance to pests and diseases. Most problems arise from environmental stress rather than insects or pathogens. Focus on watering, mulching, and site selection rather than preventative spraying.
8. Harvest and Store
Most gardeners grow Ginkgo for ornamental value rather than harvests. In regions where female trees are grown, seeds may be collected and processed carefully according to traditional preparation methods.
9. Note
If your young Ginkgo repeatedly dies back to ground level, don't automatically blame winter cold. In Mediterranean climates, summer drought stress may be weakening the plant long before winter arrives. Improving irrigation, mulching, and temporary shade may prove more effective than winter protection alone.
Kraut Crew Insight
Few trees inspire patience quite like Ginkgo. Every spring, we're genuinely excited to see that tiny green shoot emerge from the soil once again. It may only be 15 cm tall today, but every year it survives feels like another small victory. Sometimes gardening isn't about harvesting fruit. Sometimes it's simply about refusing to give up on a tree that has already survived for millions of years.

Herman’s Tough Kraut Field Notes: Solving Ginkgo biloba Cultivation Challenges
Growing Ginkgo biloba often seems simple on paper. Most books describe it as nearly indestructible, highly adaptable, and remarkably long-lived. Yet our own experience has shown that troubleshooting young Ginkgo trees can be surprisingly complex. The following FAQ section addresses some of the most common questions and challenges associated with establishing Maidenhair Trees in Mediterranean climates.
While mature Ginkgos can survive conditions that would kill many other species, young plants are not invincible. Understanding the difference between establishment challenges and long-term resilience is often the key to success.
Q: My Ginkgo dies back every winter but resprouts every spring. Is it dying?
A: Probably not. If new shoots emerge each spring, the root system is still alive. Annual dieback often indicates that the tree is struggling to store enough energy during the growing season rather than suffering fatal winter damage.
Q: Is winter cold really the problem in Zone 8a?
A: Usually not. Ginkgo biloba is hardy far beyond Zone 8a and can survive temperatures far colder than those typically experienced in Central Portugal. Drought stress, poor establishment, or insufficient root development are often more likely causes of repeated dieback.
Q: Should young Ginkgos be grown in full sun?
A: Mature Ginkgos thrive in full sun. Young trees, however, can benefit from temporary afternoon shade in hot Mediterranean climates. Shade structures, nurse plants, or developing canopy trees can reduce water stress during establishment.
Q: Why is my Ginkgo growing so slowly?
A: Several factors may contribute, including drought, root competition, poor soil conditions, or transplant shock. Ginkgos are not fast-growing trees when young and often spend several years focusing on root development before accelerating above-ground growth.
Q: Can companion plants help or hinder establishment?
A: Both. Beneficial companions such as comfrey can improve soil health and provide mulch material. However, vigorous species like Mimosa, elderberry, and butterfly bush may compete with small Ginkgos for water during dry summers. Monitoring competition is important during the first few years.
Q: When should I become concerned about a struggling Ginkgo?
A: Concern is warranted if spring regrowth becomes progressively weaker, if new shoots fail to emerge altogether, or if stem dieback begins extending below the soil surface. Consistent annual resprouting, even if modest, remains a positive sign.
