Common issues for Midland hawthorn 'Punicea' based on 10 million real cases
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.
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.
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.
Gall
Insects or diseases can cause strange protrusions on the leaves, sometimes manifesting in a range of colors and shapes.
Solutions: While galls may look alarming, the physical structures themselves pose little threat to the plant or tree and do not require chemical treatment. If the galls are unsightly, they can be removed using sterilized (10% bleach solution) pruners or loppers. Discard or destroy all removed plant parts. It is important to treat the underlying cause, as insects or diseases can create long-term damage if left untreated. After identifying the pest, natural or chemical may be used, depending upon individual gardening preferences. To treat pests naturally apply an insecticidal soap. Dilute 1 tablespoon of soap per quart of water in a spray bottle and mix gently. Spray the entire plant until the leaves are dripping, making sure to coat the underside and tops. Re-spray every 2 to 3 days. To treat organically apply neem oil, a naturally occurring pesticide, per label directions every 7 days until pests are eradicated. To treat chemically apply an insecticidal foliar spray. Follow the dosing instructions provided by the manufacturer on the product label. For fungal or bacterial causes, apply a bactericide or copper-based fungicide in the spring, following the dosing instructions provided on the product label.
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
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
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.
Prevention
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.
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.

Sap-sucking insects
Sap-sucking insects can create dense clusters of small yellow or white spots on the leaves.
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
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.

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
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.

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
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
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.
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.

Gall
Insects or diseases can cause strange protrusions on the leaves, sometimes manifesting in a range of colors and shapes.
Overview
A general symptom of plant irritation, a gall is a spherical or lumpy, tumor-like growth that appears on leaves, stems, branches and trunks of various plants, especially trees. Galls form around a potential problem or irritation, like a pearl forming around a bit of sand in an oyster shell, to separate the cause from the rest of the plant. Many form around insect damage or a localized infection.
Symptom Analysis
Abnormal growths appear on leaves or other parts of the plant. The brown or brightly colored bumps may be simple or complicated structures.
Leaf galls appear on most herbaceous plants and trees. They are more prone to develop on new growth and following mild winters in which insects and diseases were not killed by the cold.
Leaf galls look like leaf curls, nipples, blisters, or erineums (hairy growths) and can occur on upper or lower leaf surfaces.
Bud or flower galls cause these parts to be deformed in size or shape.
Stem and twig galls cause deformed growth on twigs and stems, with symptom severity ranging from slight swelling to large, knot-like growth.
Stunted plant growth is possible, as galls steal nutrients from the plant.
Long-lasting damage can occur if there are many galls or galls present for a long period of time.
It's important to note that galls, especially leaf galls, are extremely common. Noticing galls is not a cause to panic – most plants will have galls from time to time. However, it is when they are widespread or long-lasting that steps will need to be taken to remove them.
Disease Cause
There are many different processes and organisms that produce galls. Some appear when sap-sucking insects feed on leaves; some shelter developing insect eggs; some develop as a response to fungal or bacterial infection.
The most common culprits include:
Feeding or egg-laying mites and insects - the saliva and other secretions cause the plants to produce more growth hormones.
High hormone production resulting in increased cell numbers or cell size (because of this, mature plants tend not to be affected).
Fungal infection
Galls forming on leaf blades and sheaths are more often caused by viruses or bacteria.
Nematodes can also cause galls to form on plants, but these tend to form in the roots.
Parasitic plants such as mistletoe can cause galls on their hosts.

To prevent the common causes of gall:
Rake up all fallen leaves at the end of the growing season, and dispose of the leaves and all other plant debris to get rid of sites where gall producers can overwinter.
Avoid over-fertilizing plants, as it induces stress, making them more susceptible to pest problems.
Apply dormant oil in early spring to control leaf-eating insects.
