How to Water Birches 'Fascination'?

Newly planted birches 'Fascination' can be sensitive to too little or too much water, so watering 30 seconds twice a week should be enough. The important thing to keep in mind is that the soil should be moist, which means not too dry or soaking wet. Once the tree is established, there is no need to water, except in a hot summer. In summer, lay a hose on the base of the tree and water in a mild stream, allowing water to slowly run over the root system.

Cultivation:FertilizerDetail

How to Fertilize Birches 'Fascination'?

If the soil is alkaline or lacks certain nutrients, fertilize every spring and summer. Most species grow best in somewhat acidic soils with a pH value between 5.0 and 6.5. Slow-release fertilizer should be used. Fertilizer spikes are convenient and simple to use. However, you should fertilize only after a soil test determines that the substrate is lacking in nutrients.
Fertilize in early spring or summer, as this is the peak growth period when a tree requires the most nutrients. Avoid fertilizing the tree in mid-fall, as a late flush of growth may not harden before the winter and expose the young tissue to frost damage.
Cultivation:FertilizerDetail
Cultivation:SunlightDetail

What Are the Sunlight Requirements for Birches 'Fascination'?

The perfect location for birches 'Fascination' receives 6-8 hours of sunlight with shaded, cool soil. This is very important, as birches 'Fascination' has a relatively shallow root system and is thus sensitive to soil overheating or drought.
If you're in the northern hemisphere, the perfect spot for birches 'Fascination' cultivation is between the northern and the eastern side of a house, where the building can provide afternoon shade. Avoid western and southern sides, as the strong afternoon sun can dry the soil and negatively affect the tree's root system. Keep in mind that existing trees and other structures can provide afternoon shading. (If you're in the southern hemisphere, plant on opposite side.)

Cultivation:PruningDetail

How to Prune Birches 'Fascination'?

Birches 'Fascination' should not be pruned in late winter or early spring just before its dormancy period ends. This is because heavy sap flow and open wounds attract birch tree borers in their egg-laying season. Removing more than 25% of the total tree canopy will most likely result in tree death or seriously reduced growth, as with lost photosynthetic surface, the tree loses the ability to synthesize its nourishment. Also, removing too much of the canopy can expose the tree base and roots to too much sunlight.
Prune your birches 'Fascination' in late summer or early winter. If performed properly, pruning is very beneficial, as removing dead or infected branches, closely growing branches, and branches protruding out of the canopy increases the overall health of the tree, reduces tree infections, and improves the aesthetic appearance. Remember to disinfect the pruners before you move to the next branch in order to minimize the risks of contamination.

What is the Ideal Temperature Range for Birches 'Fascination'?

Birches 'Fascination' needs plenty of water and is somewhat sensitive to extreme moisture fluctuations. Most plants in genus Betula are adapted to temperate (and some species to moist) climates. Most of them grow best on moist but not wet soil. Avoid planting your tree in areas that are poorly drained or occasionally flooded, even for short periods.
Cultivation:WaterAndHardinessDetail
Cultivation:SoilDetail

What Soil is Best for Birches 'Fascination'?

plant birches 'Fascination' in an area with acidic soil protected from compression. It develops a shallow root system that can be easily damaged by soil disturbance. It is very important to choose a good planting site and avoid areas prone to soil compression, such as driveways or pathways. Avoid wet soils that harm the root.
plants in genus Betula grow best on somewhat acidic soils, with pH of 5.0-6.5, although this can vary from species to species. For example, the white-barked birch, such as paper birch (B. papyfera), can grow on alkaline soils. On the other hand, river birch (B. nigra) will likely show symptoms of iron chlorosis (yellow coloration of the leaves) in alkaline soils. Avoid planting any river birch in soil with a pH higher than 6.5.
Test your soil before you select your birch species (soil tests are available for purchase at most tree nurseries). If the tree has already been planted in soil that is slightly more acidic or alkaline, the soil can be amended. However, it can be complicated and expensive to keep these levels throughout the lifespan of a tree.
Cultivation:SoilDetail
Cultivation:PlantingDetail

How to Plant Birches 'Fascination'?

The planting location should ideally provide 6-8 hours of sunlight daily, while keeping the soil shaded, cool, and moist. The tree should be planted in a square-shaped hole 25 cm deeper than the tree's root ball. A young tree should be supported by tying it (not too tightly) to a wooden stake or rebar with a rubber or a nylon band.

Longhorn beetles
Longhorn beetles Longhorn beetles
Longhorn beetles
The longhorn beetle is a medium- to large-sized insect with very long antennae and strong jaws. Both its adult and larval stages gnaw on tree trunks, leaving small, round holes.
Solutions: Some longhorn beetles species are native insects, and they cause little damage. Therefore, these don't warrant control. Other longhorn beetles species are invasive pests that were recently introduced from other areas. These species can cause a great deal of damage to hardwood trees. Apply an insecticide containing imidacloprid as a soil injection or trunk injection following product instructions. This will enter into new grow and kill adults who feed on foliage. This will not help save trees that are already infested with large amounts of larvae, but it will save trees located near an infested tree. Contact an arborist for best control practices regarding infected trees. To properly control longhorn beetles, all host plants in a given area must be treated. Contact a local extension agent or state agency. Tracking the spread of longhorn beetles is a key component of their control.
Sap-sucking insects
Sap-sucking insects Sap-sucking insects
Sap-sucking insects
Sap-sucking insects can create dense clusters of small yellow or white spots on the leaves.
Solutions: Sap-sucking insects can be hard to spot, as they are often small and attach to the undersides of plant leaves. If you see signs of an infestation, follow these steps to eradicate it. Hand-pick bugs and remove eggs: Inspect your plants for insects and drop any you find in a container of soapy water. Look carefully at the undersides of plant leaves and squish any egg clusters you find. Use Insecticide: Targeted spraying can take out sap-sucking insects. Small infestations can be controlled with insecticidal soap, though larger outbreaks might require a stronger spray. Introduce natural predators: Many insects, including ladybugs and praying mantises, love to feast on sap-suckers. You can purchase them at garden stores and release them near infected plants, or encourage wild ones by creating habitat space.
Underwatering yellow

Underwatering yellow
A lack of water will cause the leaves to gradually turn yellow starting at the base of the branch while the entire plant appears to wilt.
Solutions: Your plant is very thirsty and needs water promptly. You can revive your plant by giving it water. The easiest technique is to slowly pour water into your plant’s soil so that the whole surface is moistened. If you pour the water too quickly, the water will flow directly through rather than diffusing throughout the soil. If your plant’s pot does not have drainage holes, do not give your plant more than about a third of the pot’s volume of water. If your plant’s pot does have drainage holes, you can add water slowly until the soil is thoroughly moistened and the water flows freely through the pot. If you trim off yellow leaves to improve the plant’s appearance, do not remove more than a third of the plant’s leaves. It may be better to wait until leaves have died and fallen off to remove them.

Longhorn beetles
The longhorn beetle is a medium- to large-sized insect with very long antennae and strong jaws. Both its adult and larval stages gnaw on tree trunks, leaving small, round holes.
Overview
Overview
Longhorn beetles are characterized by extremely long antennae which are often as long as, or longer, than the beetle's body. Adult longhorn beetles vary in size, shape, and coloration, depending upon the species. They may be 6 to 76 mm long. The larvae are worm-like with a wrinkled, white to yellowish body and a brown head.
Longhorn beetles are active throughout the year, but adults are most active in the summer and fall. Larvae feed on wood throughout the year.
Both larvae and adults feed on woody tissue. Some of the most susceptible species include ash, birch, elm, poplar, and willow.
If left untreated, longhorn beetles can kill trees.
Symptom Analysis
Symptom Analysis
Longhorn beetles are attracted to wounded, dying, or freshly-cut hardwood trees. Adults lay their eggs in the spring, summer, and fall on the bark of greenwood. There may be sap around egg-laying sites.
Once the eggs hatch, larvae called round-headed borers burrow into the trunk to feed. They may tunnel for one to three years depending on the wood's nutritional content. As the larvae feed, they release sawdust-like frass at the base of the tree.
Eventually, the larvae turn into pupae and then adults. When the adults emerge, they leave 1 cm holes in the bark on their way out. Adults feed on leaves, bark, and shoots of trees before laying eggs.
After a few years of being fed upon by longhorn beetles, a tree will begin losing leaves. Eventually, it will die.

Sap-sucking insects can create dense clusters of small yellow or white spots on the leaves.
Symptom Analysis
Symptom Analysis
Your plant has developed tiny yellowish spots scattered across the leaves that look like mold or mildew. If these marks won't wipe off, they are likely caused by sap-sucking insects like aphids, squash bugs, scale bugs, leafhoppers, whiteflies, mites, mealybugs, and more.
Each of these pests uses mouthparts to pierce leaf tissues and suck the sap. uses mouthparts to pierce leaf tissues and suck the sap. Signs of damage are difficult to spot at first, but a large infestation can quickly compromise the whole plant. You're most likely to see sap-sucking insects during the hottest months because plants make easier targets when already weakened from heat or drought.
Though sap-sucking insects are unlikely to kill your plant on their own, they can severely weaken it and make it more susceptible to disease. They may also spread viruses from one plant to another as they feed.

Prevention
Healthy plants are less likely to suffer from sap-sucker attacks. Keep them fortified with fertilizer and the right amounts of water and sunlight. Plants that receive excess nitrogen are also more susceptible to attack, so don’t overfertilize. You should also remove weeds and tall grasses surrounding your outdoor plants so as not to create habitat space for the pests.

Aged yellow and dry
Natural aging can cause leaves to turn yellow and dry out.
Overview
Overview
Regardless of the type of plant or where it is grown, at some point, it will begin to aged yellow and dry. This is a natural, unavoidable process that happens when the plant has completed all of the steps in its life.
Annual plants go through this process at the end of a single growing season. Perennial plants live for multiple years, if not tens or hundreds of years, but will still ultimately exhibit these symptoms.
Symptom Analysis
Symptom Analysis
When plants have progressed through their natural developmental stages and are nearing the end of their lifecycle, they begin showing signs of decline. Leaves will start to yellow and droop, and over time they turn papery brown and dry.
Once completely dry, the leaves begin to fall from the plant until the entire plant has dried out.
Disease Cause
Disease Cause
At the end of its life, genetic coding within the plant increases the production of ethylene, a phytohormone that controls senescence or natural aging and death. Cell division stops, and the plant begins catabolizing resources to use in other parts of the plant.
As this happens, the tissues begin yellow and drying until the entire plant is desiccated and perishes.

Common Problems

feedback
Feedback

Which species of birches 'Fascination' should I plant?

more more
It depends on your growing location. White-barked birches, such as grey birch and paper birch, are better adapted to cooler climates, while, river birch grows well in warmer and more humid areas. Native North American birch is more resilient to birch leafminer and birch borer, while white-bark birches can be more susceptible to these pests.

How much and how often should I water my birches 'Fascination' tree?

more more
It depends on the amount of rainfall your location receives. If the soil is dry, water the tree once a week with a slow water stream for at least 2 hours. Heavy water streams can damage the shallow root system and soak the soil too much.

Should I amend or fertilize the soil?

more more
Before taking any action, always perform a soil test (available in most nurseries). Only amend your soil if the pH is too acidic or too alkaline (most birches prefer soil pH between 5.0 and 6.5). Fertilize only if soil tests indicate that a nutrient is lacking.

When should I prune and fertilize my birches 'Fascination'?

more more
Prune birches 'Fascination' in late summer or early winter. If pruning is performed too late in winter, the wounds might not heal and young tissue could be exposed to frostbite. Avoid pruning during the egg-laying season of the birch leafminer and birch borer, from late spring to summer. Fertilize during the peak growth period when the tree requires the most nutrients, in early spring or summer.

Do I need to apply any mulch to the tree base?

more more
Mulching is important. It keeps the soil cool during summer and improves water retention and oxygen exchange of the soil. As it decomposes, it adds organic matter to the soil. It allows the root system to develop freely. Finally, mulching reduces soil compaction, which birch trees are very sensitive to because of their shallow root system. Apply a 2-inch layer of mulch in a 3-foot radius around the planted tree, but not next to the trunk. Wood chips or shredded bark are a good mulching choice.

  • Apply an insecticide containing imidacloprid as a soil injection or trunk injection following product instructions. This will enter into new grow and kill adults who feed on foliage. This will not help save trees that are already infested with large amounts of larvae, but it will save trees located near an infested tree.
  • Contact an arborist for best control practices regarding infected trees.
  • To properly control longhorn beetles, all host plants in a given area must be treated.
  • Contact a local extension agent or state agency. Tracking the spread of longhorn beetles is a key component of their control.
Prevention
Prevention
  • Keeping trees healthy, uninjured, and unstressed will help prevent beetle infestation. Water trees appropriately, giving neither too much nor too little.
  • Check with local tree companies about which tree species have fewer problems.
  • Avoid moving firewood as this can introduce exotic longhorn beetles.
  • Routine spraying of persistent, broad-spectrum insecticides will help prevent re-infestation of previously affected trees or infestation of unaffected trees.

Sap-sucking insects
plant poor
Sap-sucking insects
Sap-sucking insects can create dense clusters of small yellow or white spots on the leaves.
Symptom Analysis
Symptom Analysis
Your plant has developed tiny yellowish spots scattered across the leaves that look like mold or mildew. If these marks won't wipe off, they are likely caused by sap-sucking insects like aphids, squash bugs, scale bugs, leafhoppers, whiteflies, mites, mealybugs, and more.
Each of these pests uses mouthparts to pierce leaf tissues and suck the sap. uses mouthparts to pierce leaf tissues and suck the sap. Signs of damage are difficult to spot at first, but a large infestation can quickly compromise the whole plant. You're most likely to see sap-sucking insects during the hottest months because plants make easier targets when already weakened from heat or drought.
Though sap-sucking insects are unlikely to kill your plant on their own, they can severely weaken it and make it more susceptible to disease. They may also spread viruses from one plant to another as they feed.
Solutions
Solutions
Sap-sucking insects can be hard to spot, as they are often small and attach to the undersides of plant leaves. If you see signs of an infestation, follow these steps to eradicate it.
  1. Hand-pick bugs and remove eggs: Inspect your plants for insects and drop any you find in a container of soapy water. Look carefully at the undersides of plant leaves and squish any egg clusters you find.
  2. Use Insecticide: Targeted spraying can take out sap-sucking insects. Small infestations can be controlled with insecticidal soap, though larger outbreaks might require a stronger spray.
  3. Introduce natural predators: Many insects, including ladybugs and praying mantises, love to feast on sap-suckers. You can purchase them at garden stores and release them near infected plants, or encourage wild ones by creating habitat space.
Prevention
Prevention
Healthy plants are less likely to suffer from sap-sucker attacks. Keep them fortified with fertilizer and the right amounts of water and sunlight. Plants that receive excess nitrogen are also more susceptible to attack, so don’t overfertilize. You should also remove weeds and tall grasses surrounding your outdoor plants so as not to create habitat space for the pests.

Underwatering yellow
plant poor
Underwatering yellow
A lack of water will cause the leaves to gradually turn yellow starting at the base of the branch while the entire plant appears to wilt.
Symptom Analysis
Symptom Analysis
Your plant’s leaves are turning yellow due to underwatering, the oldest leaves turn yellow first. Leaves yellow from the edges towards the middle. Other signs of underwatering include the soil feeling very dry or pulling away from the edge of its pot.
Solutions
Solutions
Your plant is very thirsty and needs water promptly.
  1. You can revive your plant by giving it water. The easiest technique is to slowly pour water into your plant’s soil so that the whole surface is moistened. If you pour the water too quickly, the water will flow directly through rather than diffusing throughout the soil. If your plant’s pot does not have drainage holes, do not give your plant more than about a third of the pot’s volume of water. If your plant’s pot does have drainage holes, you can add water slowly until the soil is thoroughly moistened and the water flows freely through the pot.
  2. If you trim off yellow leaves to improve the plant’s appearance, do not remove more than a third of the plant’s leaves. It may be better to wait until leaves have died and fallen off to remove them.
Prevention
Prevention
  1. When you get a new plant, research its specific watering needs. Set reminders so that you remember to water your plants consistently. Not all plants are the same, so make sure to differentiate all of your plants in your watering schedule.
  2. You may wish to purchase a commercial soil water meter which has a long probe that you place near your plant’s roots. Be sure to check it frequently and water your plant when the soil water meter indicates that it needs watering.

Aged yellow and dry
plant poor
Aged yellow and dry
Natural aging can cause leaves to turn yellow and dry out.
Overview
Overview
Regardless of the type of plant or where it is grown, at some point, it will begin to aged yellow and dry. This is a natural, unavoidable process that happens when the plant has completed all of the steps in its life.
Annual plants go through this process at the end of a single growing season. Perennial plants live for multiple years, if not tens or hundreds of years, but will still ultimately exhibit these symptoms.
Symptom Analysis
Symptom Analysis
When plants have progressed through their natural developmental stages and are nearing the end of their lifecycle, they begin showing signs of decline. Leaves will start to yellow and droop, and over time they turn papery brown and dry.
Once completely dry, the leaves begin to fall from the plant until the entire plant has dried out.
Disease Cause
Disease Cause
At the end of its life, genetic coding within the plant increases the production of ethylene, a phytohormone that controls senescence or natural aging and death. Cell division stops, and the plant begins catabolizing resources to use in other parts of the plant.
As this happens, the tissues begin yellow and drying until the entire plant is desiccated and perishes.
Solutions
Solutions
If the yellowing and drying of leaves and flowers is a natural progression due to age, nothing can be done to slow or stop the process. Once hormones within the plant begin the process of senescence, it’s irreversible.
Prevention
Prevention
Unfortunately, there is no way to prevent plants from dying of “old age.” To help prolong their life, and put off symptoms of aged yellow and dry for as long as possible, take care of them by giving them enough water, fertilizing them appropriately, and making sure they get enough sunlight.

Common Problems

feedback

Which species of birches 'Fascination' should I plant?

more more
It depends on your growing location. White-barked birches, such as grey birch and paper birch, are better adapted to cooler climates, while, river birch grows well in warmer and more humid areas. Native North American birch is more resilient to birch leafminer and birch borer, while white-bark birches can be more susceptible to these pests.

How much and how often should I water my birches 'Fascination' tree?

more more
It depends on the amount of rainfall your location receives. If the soil is dry, water the tree once a week with a slow water stream for at least 2 hours. Heavy water streams can damage the shallow root system and soak the soil too much.

Should I amend or fertilize the soil?

more more
Before taking any action, always perform a soil test (available in most nurseries). Only amend your soil if the pH is too acidic or too alkaline (most birches prefer soil pH between 5.0 and 6.5). Fertilize only if soil tests indicate that a nutrient is lacking.

When should I prune and fertilize my birches 'Fascination'?

more more
Prune birches 'Fascination' in late summer or early winter. If pruning is performed too late in winter, the wounds might not heal and young tissue could be exposed to frostbite. Avoid pruning during the egg-laying season of the birch leafminer and birch borer, from late spring to summer. Fertilize during the peak growth period when the tree requires the most nutrients, in early spring or summer.

Do I need to apply any mulch to the tree base?

more more
Mulching is important. It keeps the soil cool during summer and improves water retention and oxygen exchange of the soil. As it decomposes, it adds organic matter to the soil. It allows the root system to develop freely. Finally, mulching reduces soil compaction, which birch trees are very sensitive to because of their shallow root system. Apply a 2-inch layer of mulch in a 3-foot radius around the planted tree, but not next to the trunk. Wood chips or shredded bark are a good mulching choice.
