Willow oak trees are very popular shade and specimen trees. Because they are fast growing and fill out with an attractive, branching shape, they are a frequent choice in parks and along wide streets. Keep reading to learn more about how to grow a willow oak and willow oak tree care.
Willow Oak Information Willow oak trees (Quercus phellos) are native to the United States. They are hardy in USDA zones 5 or 6a through 9b, making their range the whole of the west coast, most of the east coast, and the entire south and southwest. The trees are fast growing. When they are young, they have a pyramidal shape, but as they mature their branches take on a wide, even spread. The lowest branches hang down somewhat toward the ground. The trees tend to reach a height of 60 to 75 feet (18-23 m.) with a spread of 40 to 50 feet (12-15 m.). The leaves, unlike other oak trees, are long, thin, and dark green, similar looking in appearance to willow trees. In the autumn, they turn yellow to bronze in color and eventually drop. The trees are monoecious and produce flowers (catkins) in the spring that can lead to some litter. The fruits are small acorns, no bigger than ½ an inch (1cm.) across.
Willow Oak Tree Care Growing willow oak trees is easy and very rewarding. While they prefer moist, well-drained soil, they will thrive in almost any kind of soil and are wind, salt, and drought tolerant, making them popular in urban landscapes lining broad streets or filling in parking lot islands. They prefer full sun. They are, for the most part, resistant to both pests and diseases. Though they are drought tolerant, they will also perform well in soil that is perpetually wet. They’ve been used for decades as urban, street lining trees and have proven themselves to be up to the task.
It should be noted that in smaller areas, it may be best to avoid the tree, as its height can eventually overpower the area.

The neem tree (Azadirachta indica) has caught the attention of gardeners in recent years for the benefits of its oil, a safe and effective herbicide. However, that’s just the beginning of the story. This versatile plant, native to tropical India and Asia, is a valuable tree with many uses. Read on for neem tree information, including neem tree benefits and uses.
Uses of Neem Tree Oil – Familiar primarily to organic gardeners in the United States, neem oil is made by pressing the oil-rich neem seeds. The oil is highly effective against a variety of pests, including: Aphids Mealybugs Fungus gnats Whiteflies It is also useful as a natural insect repellent and is often incorporated into shampoo, soap, lotion and other skin care products. Additionally, the oil makes a great fungicide for issues like powdery mildew, black spot and sooty mold.
Bark – Neem bark isn’t widely used, although its anti-inflammatory and antiseptic properties make it a useful treatment for gum disease in mouthwash form. Traditionally, natives chewed the twigs, which served as effective, impromptu toothbrushes. The sticky bark resin is commonly used as glue. Flowers – Neem tree is widely appreciated for its sweet aroma, which honeybees love. The oil is also valued for its calming effect. Wood – Neem is a fast-growing tree that tolerates poor growing conditions and drought-prone soil. As a result, the wood is a critical source of clean-burning firewood in many frost-free regions of the world.
Cake – “Cake” refers to the pulpy substance that is leftover after oil is extracted from the seeds. It is an effective fertilizer and mulch, often used to discourage diseases like mildew and rust. It is sometimes used as livestock fodder. Leaves – In paste form, neem leaves are used as a skin treatment, primarily for fungus, warts or chicken pox.
How to Grow a Neem Tree Neem is a hardy tree that can tolerate temperatures up to 120 F. (50 C.). However, extended cool weather with temperatures below 35 F. (5 C.) will cause the tree to drop its leaves. The tree won’t tolerate colder temperatures, wet climates or prolonged drought. That being said, if you can locate fresh neem tree seeds, you can grow a tree indoors in a pot filled with good quality, well-drained potting soil. Outdoors, plant fresh neem seeds directly in the ground, or start them in trays or pots and transplant them outdoors at about three months. If you have access to mature trees, you can root the cuttings in late fall or early winter.
Neem Tree Growth and Care Neem trees require plenty of bright sunlight. The trees benefit from regular moisture, but be careful not to overwater, as the tree won’t tolerate wet feet or poorly drained soil. Allow the soil to dry between every watering. Feed the tree about once a month in spring and summer, using a light application of any good quality, balanced fertilizer or a dilute solution of water-soluble fertilizer. You can also apply a diluted fish emulsion.

Fruitless mulberry trees are popular landscaping trees. The reason that they are so popular is due to the fact that they are fast growing, have a lush canopy of dark green leaves and are tolerant of many urban conditions, plus, unlike their cousins the red and white mulberry tree, they do not make a mess with their fruit. Because of their popularity, many people become alarmed when the mulberry tree leaves start turning yellow. There are many reasons fruitless mulberry tree leaves turn yellow.
Mulberry Leaf Spot Mulberry leaf spot is caused by a type of fungi that attacks the leaves of the tree. Fruitless mulberry trees are particularly susceptible to it. Mulberry leaf spot can be identified by the leaves growing somewhat malformed, yellowed and having black spots. Mulberry leaf spot can be treated with fungicide. Even without treatment, fruitless mulberry trees can normally survive this disease. The important thing to remember is that you will need to clean up and dispose of all the fallen leaves in the fall or winter. The mulberry leaf spot fungi over winter on the fallen leaves and in the spring, the rain will splash the fungi back onto the tree, which re-infects it for the next year. Removing and destroying the fallen leaves will help prevent this.
Not Enough Water Fruitless mulberry trees grow rapidly and their root systems can grow to a massive size. What this means is that what may have been enough water one year will not be enough water the next. When the tree does not get enough water, the mulberry gets yellow leaves. A mulberry tree may be particularly prone to this during periods of drought when the leaves will be transpiring water faster than the roots can take it up.. The best course of action is too water the tree deeply about once a week. Watering deeply is better for the tree than multiple shallow waterings. A deep watering will get the water down into the root system so that more of the roots will be able to take water up at the same rate as the leaves transpire it.
Cotton Root Rot Cotton root rot is another fungus that can cause a mulberry to have yellow leaves. Cotton root rot is characterized by yellowing leaves followed by wilting. The leaves will not fall off the plant though. Unfortunately, by the time the symptoms of cotton root rot are seen, the tree has most likely been damaged beyond repair and will most likely die within a year. Calling an arborist to look at the situation is advised due to the fact that cotton root rot will continue to spread in the soil and kill other surrounding plants and trees.
Hopefully your mulberry tree will recover from whatever problem is causing the mulberry tree leaves to turn yellow. Fruitless mulberry trees are amazingly resilient and yours should bounce back in no time at all.

Originating in Japan, contorted mulberry trees (Morus alba) thrive in USDA plant hardiness zones 5 through 9. This deciduous, rapidly growing plant can easily reach 20 to 30 feet high and 15 to 20 feet wide if not controlled. This tree is also known as a contorted “Unryu” mulberry.
Contorted Mulberry Info The leaves of this attractive tree are a light green color and somewhat glossy and heart-shaped. They turn yellow in the fall. From mid to late summer, small yellow flowers bloom followed by fruit similar in shape and size to a blackberry. Fruit is white and ripens to a pink or light violet. Depending on variety, it can take up to ten years for a tree to start producing fruit. A distinguishing feature of this interesting tree is the contorted or twisted branches that are often used in flower arrangements, which help to give these plants the name ‘corkscrew mulberries'.
Growing Contorted Unryu Mulberries Many people plant contorted mulberries as an ornamental plant in the home landscape. They bring great interest during all garden seasons and draw wildlife with their fruit and foliage. Mulberry trees do best in full to part sun and require ample water while they are establishing, although they are drought tolerant once roots are established. Some people plant varieties in large containers where their growth can be controlled. They make lovely patio plants and are popular because of their fast growth.
Care of Contorted Mulberry Mulberry trees need space to spread out; 15 feet between trees is recommended. Provide supplemental water during dry conditions. If the soil conditions become too dry, fruit drop will occur. An annual feeding using a 10-10-10 fertilizer will keep the tree at its best. Pruning is only necessary to remove dead or damaged limbs and to limit crowding and control growth.
Harvesting and Using Fruit Pick fruit early in the morning when it is at the peak of ripeness. It will be deep red to almost black when it is ready. Spread a sheet on the ground and gently shake the tree. The fruit will fall to the ground. Use immediately or wash, dry and freeze. This delicious berry is great for jams, pies or when eaten fresh.

Mulberry is a deciduous, medium to large tree (20-60 feet tall) that is available in fruiting and fruitless varieties. If you currently have a mulberry that fruits, you may be well aware of the mess the fruit can create. Although the fruit is edible, there may be more of it than you can handle with an end result of a driveway that is stained purple and a car that has been bombed by bird, ahem, droppings. With such a nuisance, you may be wondering how to stop a mulberry from fruiting or mulberry fruit tree sterilization.
How to Sterilize Mulberry Trees Ask any arborist and they will probably tell you that sterilizing mulberry trees is a difficult proposition, if not impossible. Expensive chemicals are required and the potential drift can affect surrounding unprotected trees and bushes. Generally, the results are inconsistent and must be timed perfectly during fruit bloom and in prime temperature conditions for any efficacy. The best course of action to stop a mulberry from fruiting and preventing the type of mess described above is to plant a male tree or fruitless variety of mulberry. If it’s too late for that and you have a female tree, thinning or pruning the tree to reduce the amount of viable fruit is certainly a thought. You will still get some fruit but between eating some and the reduction of fruit set, you may be able to stay ahead of the untidiness. Really, the only other method to try for preventing mulberry fruit is to use a chemical application. These chemicals can be applied by you or preferably by a licensed tree company.
Chemically Preventing Mulberry Fruit An attempt can be made sterilizing mulberry trees with the use of such chemicals as Florel Fruit Eliminator. Florel contains ethephon, which will stop fruiting and breaks down into a natural plant hormone, ethylene. It must be applied at full bloom at just the right temperatures (60-95 F./16-32 C.) and will cause fruit to drop prior to setting. All conditions must be optimal, including a lack of disease or insect infestation, sufficient irrigation, excellent drainage and soil conditions. An issue with any of these puts the tree under stress, causing its natural production of ethylene. Too much ethylene will damage the tree, causing defoliation, stem damage and leaf scorch. For this reason, even professionals have a difficult time determining the best time for application.
A professional company may also use a deflowering hormonal solution applied internally as a basal or tree trunk panacea for mulberry fruit tree sterilization. Known as Snipper, this is an acid solution that is micro-injectable and again, has a window of optimum opportunity for use. All hormonal sprays should be applied during flowering before fruit set. This timing is crucial and any derivation will result in wasted time and money.
Other chemicals may be useful for mulberry sterilization. Consult with an arborist or the like for professional grade information. Professional application is likely to be costly, so keep that in mind. If all else fails, consider the removal of the tree (although that costs a pretty penny too!) and replanting of a less disorderly specimen.

Mulberries are delicious berries akin to blackberries, which can be used in much the same way. Generally speaking, you will rarely find these delicacies at the local farmers market let alone the supermarket, as they have a short shelf life. The best way to ensure a good supply is by planting your own mulberry tree, but keep in mind these heavy bearers are prone to heavy mulberry fruit drop and can create quite a mess.
Mulberry Tree Dropping Fruit Unlike other fruit bearers, mulberry trees begin bearing at an early age and quite heavily at that. Soon enough, you will have entire buckets of berries, far more than the average family can eat. Not too worry. Fruit drop in mulberry trees is very common, hence the mention of a mess. Birds will get to them but probably not before they stain the drive or sidewalk or even the soles of your shoes to be tracked indoors. Like all fruit trees, premature fruit drop of mulberries may occur. This is generally due to several factors: weather, inadequate pollination, pests or disease, and overbearing.
What to do About Ripe Mulberry Fruit Drop As mentioned, ripe fruit drop in mulberry tree cultivation goes with the territory. This is the nature of this particular berry tree. You can either just “go with it” or enjoy the plethora of fruit loving birds the tree attracts, or you can lay a tarp beneath the tree during mulberry fruit drop season, which will make a tidy and rapid method for harvest. Going in forewarned, for those who have not yet planted a mulberry, choose a site that does not hang over your driveway or sidewalk because fruit drop in mulberry trees is a guarantee, not a possibility. – Of course, you can always choose to grow a fruitless mulberry tree too, or consider sterilization of the fruit tree.
How to Fix Premature Fruit Drop of Mulberries For any fruiting tree, the number one reason for premature fruit drop is weather. Given that you can’t control the weather, you can take steps to protect the tree if inclement frost is forecast during the growing season. Cover the tree with sheets, burlap or the like, or string holiday lights around the tree to keep it warm. Wind can also take its toll and result in premature fruit drop. Be sure to stake young trees to prevent damage. Companion planting can boost pollination around your mulberry and lessen the chances that inadequate pollination results in premature fruit drop. Also, avoid using pest control sprays that may affect the pollinators during bloom times. Pests and diseases can be combated with a pesticide or fungicide if the infestation is serious. Keep in mind that the use of pesticides during blossoming may exacerbate premature fruit drop by killing bees and other beneficial insects.
Lastly, premature fruit drop is often the result of overbearing, which is most common in young trees that have less stored nutrition than mature trees. If the tree is in competition between saving itself and fruiting, sending nutrients to produce berries or survive itself, obviously the tree wins. Sometimes trees prematurely drop fruit due to the sheer weight of it on their branches. It is of paramount importance to thin the young fruit before the tree drops it. Use small pruner and leave 4-6 inches between fruit clusters. You can also pinch off blossoms before the petals drop.
Follow all the above and barring unforeseen circumstances you should be enjoying an antioxidant, protein packed smoothie for, well, the rest of the year given the proliferation of berries you’re bound to harvest!

Mulberry trees (Morus spp.) enjoyed popularity in years past as ornamental shade trees as well as for their copious edible fruit, which can be eaten raw or made into luscious preserves, pies and wine. Interested in learning about how to grow mulberry trees? Read out all about growing mulberry fruit trees and mulberry tree care.
Growing Mulberry Fruit Trees While people love mulberry fruit, birds also love the berries and the tree is a beacon that attracts dozens of, ahem, messy guests. The tree also has an unwelcome habit of becoming invasive. Unfortunately, this brought the growing of mulberry fruit trees to a screeching halt in any but the most rural areas. Mulberry trees do have redeeming qualities, though, and one of the most outstanding is the minimal care they require. Before we learn about how to care for mulberry trees, here’s a brief synopsis of the three types of mulberry trees most commonly grown.
Black mulberry – The most flavorful berries come from the black mulberry (Morus nigra). These trees are native to western Asia and are only adaptable to USDA zone 6 and warmer. Red mulberry – Hardier than black mulberries, red mulberries (Morus rubra) are native to North America where they thrive in deep rich soils found along bottomlands and streams. White mulberry – White mulberries (Morus alba tatarica) were imported from China, introduced into colonial America for silkworm production. White mulberries have since naturalized and hybridized with the native red mulberry.
How to Grow Mulberry Trees Mulberry trees bear small, unremarkable blooms that become plentiful fruits that look much akin to a slender blackberry. The berries ripen in stages and drop from the tree as they mature. The trees are hardy to USDA zones 4/5 to 8 depending upon the variety. They prefer full sun and rich soil but will tolerate part shade and a variety of soils. They are easy to transplant, salt tolerant and perfect for erosion control, not to mention the delicious berries. Some cultivars are wind-resistant and make wonderful windbreaks.
Deciduous trees, all three species attain various sizes. White mulberry can grow to 80 feet, red mulberry around 70 feet and the smaller black mulberry may get to 30 feet in height. Black mulberries can live for hundreds of years, while red mulberry maxes out at 75 years of age. Mulberry trees should be planted in full sun with no less than 15 feet between trees, ideally in warm, well-draining soil such as deep loam. Don’t plant them near a sidewalk unless you don’t mind the staining or the potential tracking in of squashed berries (of course, if this is a problem for you, there is a fruitless mulberry variety too!). Once the tree has established, there is very little additional mulberry tree care required.
How to Care for a Mulberry Tree There really isn’t too much to worry about with this hardy specimen. The trees are fairly drought tolerant but will benefit from some irrigation during the dry season. Mulberries do well without additional fertilization, but a 10-10-10 application, once per year will keep them healthy. Mulberries are even primarily free from most pests and disease.
Pruning Mulberry Trees Prune young trees into a tidy form by developing a set of main branches. Prune lateral branches to 6 leaves in July to facilitate the growth of spurs near the main limbs. Do not prune heavily since mulberries are prone to bleeding at the cuts. Avoid cuts of more than 2 inches, which will not heal. If you prune when the tree is in its dormancy, bleeding is less severe.
Thereafter, only judicious pruning of mulberry trees is necessary, really only to remove dead or overcrowded branches.

Mulberry (Morus spp.) trees are fast-growing, deciduous trees known for their variable leaf shapes, their delicious berries, and the terrible stains those berries can make if they hit the sidewalk rather than someone’s mouth. Some have red fruit while others produce tasty purple or white fruit. A fruitless cultivar exists for those not interested in those yummy, messy berries. Mulberry trees can reach 30’-70’ depending on the species. They are fantastic shade trees. Due to their quick growth, pruning mulberry trees is often necessary.
Mulberry Trimming Proper mulberry tree pruning techniques depend on your landscape goals. If you want to create a shady spot that provides food and shelter for birds as well as biomass for your compost bin, only cut out small, dead, diseased, crossed-over and oddly oriented branches. In this case, mulberry trimming can be done every two to three years. If your primary goal is fruit production for human consumption, then mulberry trimming should be done every year to control size and to keep most of the fruit within easy reach. Note that mulberries bloom and fruit on the previous year’s growth, so extensive pruning will reduce fruit production. Pruning mulberry trees that are too large for their space is often executed via a technique called pollarding. With pollarding, all the smaller branches are removed annually to a selected area on larger scaffold branches. I don’t like to recommend pollarding because it is mostly done wrong. When the pollard form of mulberry tree pruning is done incorrectly, it can leave a tree that is unsafe, ugly and prone to disease.
How to Prune a Mulberry Tree If you are wondering how to prune a mulberry tree, start with sharp, clean tools. Do not struggle while cutting through a branch. If this happens, your tool is too small. Use a hand pruner for cuts under 6” and loppers for cuts 1” to 2”. You can also use a good saw for cuts 1” and larger. Try not to cut branches larger than 2” in diameter. Mulberry trimming should not be done on large branches unless you accept the fact that large wounds don’t heal very quickly and leave open the door for pests and disease and heart rot. Pruning trees in pollard form should be started when the tree is quite young and the scaffold branches have grown to the height you wish for in the canopy. Always cut the smaller branches back to their base on the scaffold. A round callused knob will form over the years. Always cut to the knob but not into it. Do not leave a stub that is more than ½” at the knob. Do some research on pollarding before you cut the tree. If you inherit a large tree that was pollarded in the past but not maintained properly over the years, hire a certified arborist to get it back into shape.
When to Prune Mulberries Mulberry tree pruning is easiest when the tree is dormant. You can see the structure of the tree without it being obscured by leaves. Don’t prune when the weather is very cold. When the temperature is under 50 F. (10 C.), it is harder for the tree to seal off its wounds. A good time for mulberry trimming is in spring prior to the buds turning green.

The mulberry bush is not just a folkloric song lyric. You won’t find these sweet, tangy berries in the supermarket due to their short shelf life, but they are easy to grow, abundant, and fast growing, which makes them perfect for containers. If you’re interested in growing mulberries in containers, keep reading to find out how to grow a mulberry tree in a pot and other dwarf mulberry tree facts.
Dwarf Mulberry Tree Facts Mulberries are suited to USDA zones 5-10. In the ground, mulberries grow into a large bush, but a container grown mulberry tree’s size can be kept smaller (2-6 feet tall) by pruning just after fruiting. Pruning a mulberry also encourages the plant to produce berries again, resulting in several crops throughout the growing season. Mulberries may be female, male or bisexual. If you are growing from seed, you are more likely to get either a male or female. Commercially sold mulberries are bisexual or self-pollinating. The plant blooms in the early spring and is quickly followed by a dense crop of large juicy berries, about the size of a big blackberry. This berry is so prolific; it even yields well in its first year and may produce several crops.
The children’s song ‘Pop goes the weasel’ isn’t the mulberry’s only claim to fame. Mulberry foliage is the silkworm’s favorite food and has been cultivated for centuries specifically for this purpose. The practice of breeding silkworms for their raw silk production is called ‘sericulture’ and has been around for over 5,000 years in China. Mulberry trees also have long pliable branches perfect for weaving into baskets, fences, and screens. All these interesting uses aside, the number one reason for growing a mulberry is for its fruit. The luscious berries can be eaten fresh, dried, frozen or made into pies, jams, and frozen desserts. They can also be turned into wine or the juice can be used as a dye. Intrigued? So, how do you grow a mulberry tree in a pot and is there any special care needed of mulberries in pots?
Container Grown Mulberry Trees There isn’t much in the way of special care for mulberries in pots. They are extremely forgiving plants. Full sun exposure will make your mulberry happiest. Interestingly, the tree will do quite well with wet roots, but it can also be drought tolerant once established. They are also frost tolerant, although it is best to mulch around the plants to protect the roots from freezing and thawing. Mulberries are tolerant of a variety of soils but when potting them, it’s best to use a good quality potting medium amended with some nutrient rich compost. Feed the tree at regular intervals during the growing season with a balanced fertilizer, liquid seaweed or water with compost tea. Allow the surface of the soil to dry between waterings and then saturate the soil.
You can prune ever-bearing varieties at any time to retard their growth. Otherwise, cut back leggy plants in the late winter or early spring. Berries are formed on new growth. Mulberries have little to no issue with foliage or root diseases. They are, however, susceptible to spider mites, whiteflies and mealybugs, but these are usually fairly easy to manage.

You will probably not find mulberries at the grocers (maybe at the farmers market) because of their short shelf life. But, if you live in USDA zones 5-9, you can enjoy your very own mulberry tree harvest. The question is when to pick mulberries? This leads to a follow up question of how to pick mulberries? Read on to find the answers.
Mulberry Tree Harvest Mulberry trees attain a height of between 20-30 feet. They make lovely, fast-growing landscape trees with the added bonus of producing delicious berries and leaves suitable for steeping as tea. The berries are really the stand out though. They look much like elongated blackberries and are sinfully sweet. Starting a mulberry tree from seed can be difficult. The seed needs 90 days of cold, moist stratification and even then has a low germination rate. If you dislike failure, it might be advisable to purchase a young tree, especially if you want fruit quicker for harvesting. Mulberry trees like full sun in moist, slightly acidic soil (pH of about 6.0). They need to be planted deep enough to support their extensive root system.
When to Pick Mulberries A little patience is required before you can begin harvesting the mulberry trees. It will take about three years before you can sample the fruits of your labor and mulberry harvesting can commence. Mulberry harvesting season begins in mid-June through August. You will be looking for fruit that is large, black and sweet, so yes, a taste test is in order. If the fruit is ripe, then what?
How to Pick Mulberries The time for harvesting the mulberry trees has arrived. There are two methods for picking the fruit. You can hand pick it, which depending upon your disposition can be tedious or relaxing, or you can use an old sheet or tarp to hasten the process. Spread the tarp under the mulberry tree and then shake the branches. Gather up all the fallen berries. Take care not to layer the berries too deep in the container or you will end up with a lot of crushed berries.
If you can keep your hands off them, mulberries will keep in the refrigerator, unwashed in a covered container for several days. Or freeze the berries for later use. Wash them and gently pat them dry, then pack them in freezer bags. Frozen berries will store for several months.
