What Is an Ash Tree, Anyway?

Ash trees, native to the eastern United States, belong to the genus Fraxinus and the olive family. They're popular in landscapes, lawns and along streets, where they need little care and provide cool, leafy shade. Of the 45 to 60 species, the most common are white, black and green ash trees. They turn beautiful shades of yellow and burgundy in fall. Most are deciduous, but some hold their leaves. They're drought tolerant and hardy in USDA Zones 2 to 9.

Female ash trees are easy to identify by their clusters of winged fruits, called samaras. The fruits typically remain on the trees until late fall or early winter, when they can fall by the thousands. Female trees may or may not produce fruits in a given year, but males never produce fruits.

Ash trees have clusters of five to 11 leaflets with smooth or toothed margins. Once the trees mature, ridges with diamond shapes are visible on their bark. Younger trees have relatively smooth bark.

Soil Types

Ash trees can tolerate a wide range of soil types including sand, loam, clay and many variations in between, but prefer loam high in organic content. You can do a quick test of your soil by digging down a few inches and picking up a handful from the ground. Squeeze the soil in your hand. If it stubbornly holds together and does not break apart with a poke, it has high clay content. If the soil has a dark color and crumbles with a poke, it mostly consists of loam. Soil that doesn't hold together at all is sandy. Ash will survive in all of these soils, but will do best in the darker, crumbly, organically rich environment.


Green Ash Information: Tips For Growing Green Ash Trees - garden

Ash is one of the trees that is native to the UK. It is a delightful addition to your garden.

Growing ash trees:

Ash trees can be purchased as saplings from a garden centre or specialist. Alternatively you could have a go at growing your own ash tree from seed. Ash 'keys' as the seeds are known, ripen during September and October. You should wait for the green 'keys' to dry to a brown colour before planting as germination will then be more successful.

The seeds should be 'de-bunched' or separated by hand. Keep the seeds you want to plant in a cool, dry place. A bag in the fridge is ideal. You soak the seed for 24 hours in cold water, change the water and then place the seed in new water for a further 24 hours. Drain the water and plant seeds into a large pot with a well-draining potting medium. Place stones or crocks in the bottom of the pot to increase drainage. You will have to have patience because the pot must then be left outside for 18 months for the seed embryo to mature. After 18 months making sure the pot gets enough water if it is very dry and protecting seeds from mice and birds, you can then sow the seeds. You can see why most people will choose to buy a sapling instead of going through all that effort.

Ash will grow quickly if given enough water. It is a good idea to reduce the frequency of watering when it gets towards autumn. It is also absolutely essential to make sure that ash saplings are well fed. They do not like an acid soil so if your soil tends that way, the sapling will benefit from a top dressing of garden lime.

Whether you have bought it of grown it yourself, when you transplant the ash tree to its final home you should make sure that the surrounding area is weed-free and dig a hole big enough to accommodate the root ball. Always plant to the same depth as it was in the pot.

One established, ash grows fairly quickly, but with thrive particularly well on chalky or alkaline soil, in a wet area with lots of light.
