A ginkgotree, also known as maidenhair, is a special tree, a living fossil and oneof the most ancient species on the planet. It’s also a lovely ornamental orshade tree in yards. Once ginkgo trees are established, they require littlemaintenance and care. But considering ginkgo water requirements will help youensure the trees in your garden are healthy and thriving.
Watering ginkgo trees is similar to other trees in thelandscape. They tend towards needing less water and being more tolerant ofdrought than overwatering. Ginkgo trees do not tolerate standing water andsoggy roots. Before even considering how much to water your tree, be sure youplant it somewhere with soil that drains well.
During the first few months after you plant a young, newtree, water it nearly every day or a few times a week. Water the roots deeplyto help them grow and establish. Just avoid soaking the soil to the point ofbeing soggy.
Once established, your ginkgo tree will not need a lot ofadditional watering. Rainfall should be adequate, but for the first few yearsit may need some extra water during dry and hot spells of summer weather.Although they tolerate drought, ginkgoes still grow better if provided withwater during these times.
You can water your young, establishing ginkgo trees by handwith a hose or with an irrigation system. The former may be the better choice becausethese trees don’t need regular watering once established. Just use the hose tosoak the area around the trunk where the roots are for several minutes.
Ginkgo tree irrigation can be problematic. With a sprinklersystem or other type of irrigation, you run the risk of overwatering. This isespecially true with more mature trees that really don’t need much more thanregular rainfall. If you water your grass with a timed sprinkler system, makesure it is not watering the ginkgo too much.

When established, Ginkgo biloba grows into a large, decorative tree with few care needs. Hardy in U.S. Department of Agriculture plant hardiness zones 3 through 8, Ginkgo biloba is also called maidenhair tree, and features rich green, fan-shaped leaves that turn bright yellow in fall. The growth rate of a newly transplanted maidenhair tree is slow, though adequate water and fertilizer help the tree establish and grow more quickly. Frost protection isn't needed. The outer pulp of the Maidenhair tree's fruit seeds as well as the raw seed kernels are toxic if ingested, and may also cause dermatitis.
Regular watering is essential for the first 2 to 3 years. The soils around the tree should be consistently moist. Avoid letting the soils dry out in-between watering. The tree is a hardy species once mature and does not require much watering.
Subsequently, question is, do ginkgo trees have deep roots? General: The Ginkgo is a medium to large tree that reaches 20–35m tall, although some specimens in Page 2 China are over 50m tall. Ginkgo trees often have angular crown and long, somewhat erratic branches. They are usually deep rooted and resistant to wind and snow damage.
Simply so, why are my ginkgo tree leaves turning yellow?
Ginkgo are also subject to chlorosis if your soil is alkaline chlorosis will turn the leaves yellow, but they typically will have a deep green fan pattern within the yellow leaves. If the foliage is falling off without turning yellow first, it is a sign of root stress or of heat stress.
What does a ginkgo leaf look like?
Features simple, fan-shaped bright green leaves that are 2–3" long and just as wide. Provides attractive yellow fall color.
Ginkgo biloba trees are attractive enough to be used as specimen plants in your landscaping, particularly because of their golden fall foliage color. They are more tolerant of compacted soil than many other types of trees. They are also disease-resistant and tolerate urban pollution. All of these qualities—along with their small leaves—make them good choices for planting along city streets, where they can grow into tall shade trees. At the other end of the spectrum, they are also used for Japanese bonsai.
Whether for city streets or for people's yards, the male trees are preferred (unless you have allergies), because they are fruitless. Female trees bear a fruit-like product (actually a seed ball) that not only emits a foul odor but also is slippery when it drops down on sidewalks or driveways. Cleaning up after female Ginkgo biloba trees is a high-maintenance task. The problematic "fruit" is about the size of a cherry tomato. Fortunately, all-male cultivars have been created through grafting. Buying one of these cultivars gives you a way to experience the beauty of the tree while avoiding the mess.

Love the living fossil - Ginkgo.
I planted my first one in 1972. I purchased at Kmart in Nashville, TN. It would be approximately 90’ tall now and 3.5’ dbh if the successive landowner didn’t hate raking leaves. So he cut it down even in top notch health. One in Nashville I measured at 90’ tall and 5’ dbh in 2017. That one reminds me of the great Hiroshima survivor in that it has developed evident vertical flutations around the trunk. They can become as big as any tree in TN. I’ve planted many in Nashville and here at my Level 4 Arboretum, http://www.WhiteHouseArboretum.com . Unlike most commercially planted Ginkgos, under good conditions they are not open and spindly, yet become thick and dense . read more crowned. With beautiful, full, pyramidal crown. I’ll try to round up a few of my pictures to post. Randy Allen

Love the tree! Last spring i bought 100 seeds and 60 of them germinated. Most of them were planted in bargain poting mix. Some in a premium mix. They did experience some neglect but most of them are 8" tall now in the late fall. There's a few "runts" about 1 1/2". For germating i kept the soil evenly moist and compared to other trees i germated at the same time they seem temperature sensitive. All but the ginkgos didn't germaninate till the soil temperature was near 65°f then they came up like corn. mine were in a cold frame.

Many of these ginkgo trees are planted along Capitol Blvd. in Boise and are doing very well. I think they are 25 years old or so, and put on quite a display in the fall.
They are planted in various parts of the Boise Valley and don't seem to be too fussy about soil types.

I have all the right conditions for this tree: lots of rain, sandy/loam soil, etc. I didn't have full sun. It has grown about 6 inches in 3 years. It looks perfectly healthy but just kind of hangin' out there. I just transplanted it into a flower border where it will get regular watering, full sun, and nutritious mulch with the other plants. My only concern is that it will out-grow its spot, providing too much shade for the other plants. I bought it for the foliage, both green and yellow, and for the dainty leaf shape and movement. It hasn't disappointed me on that corner.

One of the most distinctive and beautiful of all deciduous trees.
If you're growing it only as an ornamental, buy only bud-grafted male cultivars, as the fleshy seed covering that females drop is messy, stinks of vomit and contains the same resin that causes poison ivy rash. Seed-grown plants take 20 to 50 years before their sex can be determined. Freed of their coverings, the seeds are considered a delicacy by the Chinese, and are used in both traditional and modern medicine.
Males make a great street or shade tree where there is room for the stout trunk. In their youth, they may be gawky and sparsely branched, but in maturity they're magnificent.

Tough and adaptable, tolerant of salt, heat, poor soils, and air pollution, their most important requirement is good sun. No significant pests or diseases.

These were among the first east Asian trees encountered by European plant explorers and cultivated in the west, because every Confucian temple or monastery had to have at least one. They have been found growing in the wild only in the last decade.
This tree is a living fossil, and a kind of (no longer) missing link between the conifers and the other flowering plants. Plants that are recognizably ginkgos appear in fossils dating back 250 million years, 2 1/2 time the age of that other famous living fossil, the dawn redwood.

I have been growing this tree in my Sterling, MA yard (zone 6) for a few years and have nothing but good things to say about it. Currently it is about 3 feet tall and grows about 6-8 inches per year. It seems to tolerate low rainfall to some degree as we had very little rain this past summer, but it thrives when the soil is kept moist. The only caution I have is in regards to animals sampling the tree. I had another Ginkgo that was about 12 inches tall and each years growth was snipped off by rabbits and chipmunks, so if planting a small seedling, I would advise protecting it with some sort of fencing, etc. until it grows tall enough to be out of reach.

There is a very large Ginko on the grounds of the Crawford Museum in Devou Park, just outside Covington, KY. I asked a staff member and they believe it's of sufficient age that it may have been sent to the family that owned the property by Thomas Jefferson, since they were know to be in contact with him and he had acquired some ginkos for Monticello.

Ginkgo has long been grown as a sacred tree in China and Japan and is often referred to as a "living fossel" - a single tree can live as long as 1000 years and the trees alive today are almost identical to those in fossil records predating the evolution of mammals!
We use extracts from the leaves of this beautiful tree to make organic skin care. Ginkgo leaves contain flavonoids and terpenoids - all potent antioxidants. For this reason the extracts are used in skin care as a free radical neutralizer (anti-aging treatment).

About 10 years ago, we planted a ginkgo here in SW Louisiana, not knowing a thing about it except that it's pretty. Since then we've had drought, freeze, rain and hurricane. It's been almost totally ignored, with occasional cow manure compost tossed around it. The hummingbirds, bluebirds and warblers like the branches and the woodpeckers have rows and rows of holes poked around the trunk. When we first got it, it was almost burned down by a nearby fire and another tree fell on it. I'd definitely call it a hardy tree that's easy to grow! It's about 12 - 15 feet tall, in spite of us.

These trees have the most beautiful golden foliage in the Autumn. They hold their leaves longer than a lot of trees, so they are easy to spot going down the road.
Most have a nice regular shape with alternating branches that looks well in a landscape. The leaves are small, and do not make much of a mess when dropped.

The Ginkgo tree is one of the toughest plants around. In fact several trees survived the Atomic bomb dropped on Hiroshima in WW 2. All the trees were within about a mile and some were about a half mile from the blast and survived!

Gingkoes can generally be grown throughout the US, but here is some useful information for anyone wanting to plant one in a hot climate (such as Texas). A Gingko tree can scorch badly in full sun, especially if it is a young specimen. You are better off planting this tree in a spot with protection from the late afternoon sun. In fact, it makes a great understory tree and we have found that a Gingko will flourish in as little as four hours of daily sunlight. As the tree matures, its own leaves will protect its somewhat tender bark and allow it to grow well in a full sun location. It is also considered to be extremely slow growing. We have found that with 2-3 applications of moderate-rate nitrogen fertilizer per year, a Ginkgo can grow at a nice pace - comparable to a Redbud or Mexican. read more Plum.
