Yellow edges
Yellow edges disease is a common health issue affecting the Old fashioned weigela 'Wings of Fire'. It discolors the leaves' margins into yellow, weakens the plant, and may cause death if untreated. It often attributes to nutrient deficiencies or pest infestations.
Flower withering
Flowers may dry out due to a sudden change in environment or because the plant has completed its normal flowering period.
Solutions: If flower withering is a natural progression due to age, there is nothing that can be done to slow or stop the process. Once hormones within the plant begin the process of senescence, it’s irreversible. For lack of water, immediately water the plant using room temperature rainwater, bottled spring water, or filtered tap water. Water container plants until excess water drains out the bottom; water in-ground plants until the soil is soaked but there isn’t standing water on the surface. In the event of nutritional deficiencies, the best solution is to use a granular or water-soluble liquid fertilizer, and apply it to the soil at about half the recommended dosage. Keep it off the leaves and make sure granular products are watered into the soil well. If the plant is infected with a bacterial or fungal pathogen, there is no course of treatment that cures the diseased plants. The best solution is to remove the infected plants and dispose of the plant material off-site. Do not put in a compost pile.
Wilting after blooming
Flowers may wither for a variety of reasons.
Solutions: Check the soil or potting medium. Coarse textures can allow water to drain too rapidly, preventing the plant from taking up enough. If the soil and roots seem very dry, add sphagnum moss or other mediums that hold water. Water according to recommendations for each plant's species. Low humidity can be corrected by misting the plant regularly or placing it near a humidifier. Keeping it near other plants helps, too. Keep the environment consistent in terms of temperature, humidity, and lighting. Keep it away from vents, heaters, and air conditioners, and avoid moving it to locations where it will experience a temperature shock. Hot, dry heat, and cold drafts are problematic for many plants. Especially if the plant is outside, it could be experiencing heat or light stress. Try moving it to a shadier location.
Leaf scorch
Leaf blight causes leaves to dry out and turn brown starting at their tips.
Solutions: The solution to leaf scorch will depend on the cause, however, in general all cultural care methods that improve plant health and root functionality will reduce symptoms. Mulching the root zone (preferably with wood chip mulch) helps retain moisture, reduce evaporation, and promotes a healthy, functional root environment that is critical for water movement to the leaves. Check the root collar for girdling or circling roots that strangle the trunk and limit water and nutrient movement. Protect trees from severe root damage of nearby construction and excavation. If fertilizer burn is to blame, irrigate the soil deeply to flush out excess fertilizer salts. However, keep in mind that fertilizer runoff is an environmental pollutant. Avoiding excess fertilization in the first place is the best approach. If soil testing has revealed a potassium deficiency, apply a potassium fertilizer and water well. Even if you have enough potassium in the soil, plants will not be able to take it up if the soil is consistently too dry. Severely affected twigs may be removed using a pair of sharp and sanitized pruning shears, as weakened branches are susceptible to secondary infections. If your plant has bacterial leaf scorch, there is no cure. Antibiotic injections applied by a professional can reduce symptoms for a season, however, the above cultural management methods are the best options to reduce symptoms and prolong life. An infected plant will likely die within ten years.

Flower withering
Flowers may dry out due to a sudden change in environment or because the plant has completed its normal flowering period.
Overview
Flower withering occurs when flowers become weak, droopy, wilted, or faded until they can’t be revived. During withering, they begin to wrinkle and shrink until the flower becomes completely dry or dead.
Any flowers, regardless of the plant type or the climate they are grown in, are susceptible to withering. It is a worldwide problem across houseplants, herbs, flowering ornamentals, trees, shrubs, garden vegetables, and food crops.
Unlike wilting—which withering is often confused with—withering can be caused by different things and is often due to more than a lack of water. Withering can be fatal in severe cases.
Symptom Analysis
Flower withering progresses from very mild cases to severe occurrences that kill the flower. The severity of the symptoms is related to the cause and how long the condition is allowed to progress before action is taken.
Wilted, droopy flowers
Petals and leaves begin to wrinkle
Brown papery streaks or spots appear on the petals and leaf tips
Flowerhead shrink in size
Petal color fades
Yellowing leaves
Complete death of the flower
Disease Cause
The main causes of flower withering include natural age progress, lack of water, nutritional deficiencies, and bacterial or fungal diseases. It’s critical to determine the underlying cause when flower withering is noticed. This will guide the best course of action, if treatment is possible.
Check the soil for moisture and then closely examine the entire plant for signs of nutrient deficiencies. If neither of those appears to be the cause then cut open the stem below a flower. If a cross-section reveals brown or rust-colored stains it is safe to assume that this is a bacterial or fungal infection.
If the flower is nearing the end of its normal lifespan, genetic coding within the plant increases the production of ethylene, a phytohormone that controls senescence, or cell aging and death. Cell division stops and the plant begins breaking down resources within the flower to use in other parts of the plant.
In all other cases, flower withering happens when the plant seals off the stem as a defense mechanism, stopping transport within the vascular system. This prevents further water loss through the flowers but also stops bacteria and fungi from moving to healthy parts of the plant. Once water and nutrient transport stops, the flower begins to wither and ultimately die.

Wilting after blooming
Flowers may wither for a variety of reasons.
Overview
Wilting after blooming is sometimes a natural aging process of the flower, while other times it may indicate a problem. Orchids, for example, can bloom for anywhere from two weeks to three months, so wilting after a few days signals a problem for most varieties. This can happen to virtually any ornamental flowering plant, but those with shallow roots and limited tolerance for drought, full sun, and low humidity are more susceptible.
This is a common problem, and often has an easy fix. Sometimes, however, it is the result of more serious causes such as pests or disease of the root system.
Symptom Analysis
At first, flowers may look a little limp.
Petals may start to appear dried out and turn brown.
Eventually they may drop off the plant all together.
Disease Cause
Wilting blooms can be a sign of an unhealthy root system. Any condition that prevents the plant from absorbing enough water and nutrition can result in wilting blooms and sometimes other symptoms. If the plant doesn’t have enough water, it cannot maintain appropriate pressure within stems, leaves, and blooms, causing them to wilt.
This can result from physical damage – for example from root breakage during re-potting or attack by insects like cutworms. If you recently re-potted your plant, physical damage to the roots is a likely cause. If you see insects, they may be eating leaves, roots, or flowers. Fungal infections can also cause root rot and damage, preventing water and nutrient uptake.
Finally, wilting blooms can result simply from age. If no other symptoms are visible, it may simply signal the natural end of the flower’s lifespan. If it seems premature, this may be caused by environmental factors: water, humidity, light, or stress. Under-watering is a common cause. Similarly, plants adapted to high humidity dry out easily when humidity is low, like during winter or in dry climates. Too much light can also stress plants that need shade, causing blooms to wilt.

Leaf scorch
Leaf blight causes leaves to dry out and turn brown starting at their tips.
Overview
Leaf scorch refers to two general conditions: physiological leaf scorch and bacterial leaf scorch. It causes leaves to discolor starting along the margins, and eventually die.
Leaf scorch development is most common in the hot, dry season, becoming most noticeable in late summer. However, it can occur at other times of the year. It most often affects young trees and shrubs, but it can also affect flowers, vegetables, and other plants.
Leaf scorch can get progressively worse over multiple seasons. If the root causes are not addressed, leaf scorch can lead to plant death.
While you cannot reverse the damage caused by physiological leaf scorch, you can prevent further damage. With proper management, plants will fully recover. However, there is no cure for bacterial leaf scorch, which is a systemic infection.
Symptom Analysis
Yellow, brown, or blackened leaves starting with the leaf margins
Dying twig tips on trees and shrubs as leaves die and fall
Often there is a bright yellow border line between the dead and living leaf tissue
Disease Cause
There are numerous contributing causes of leaf scorch.
Bacterial leaf scorch is caused by the bacterium Xylella fastidiosa. The bacteria block the xylem vessels, preventing water movement. Symptoms may vary across species.
Physiological leaf scorch most commonly occurs when a plant cannot take up enough water. Numerous conditions can lead to this issue, particularly an unhealthy root system. Some causes of an unhealthy root system include overly-compacted soil, recent tillage, root compaction and severing due to pavement or other construction, drought, and overly-saturated soils.
Potassium deficiency can contribute to leaf scorch. Since plants need potassium to move water, they cannot properly move water when there is a lack of potassium.
Too much fertilizer can also cause leaf scorch symptoms. The accumulation of salts (including nutrient salts from fertilizers, as well as salt water) accumulate at the leaf margins and may build up to concentrations that burn the tissues.

Water plants according to their needs -- either keep the soil slightly moist or allow the top inch or two to dry out before watering again.
Fertilize lightly on a consistent basis, depending upon the plant’s growth. Quick-growing plants and those that flower or develop fruit will need more frequent fertilizing than slow-growing plants.
Purchase plants that are certified disease- or pathogen-free.
Look for disease-resistant cultivars.
Isolate plants showing disease symptoms to prevent the spread to neighboring plants.
Practice good plant hygiene by removing any fallen plant material as soon as possible.

Prevention
Read up on moisture, light, and soil type preferences for each plant to avoid underwatering, incorrect light levels, or other conditions that can cause wilting blooms.
Avoid re-potting during the flowering period. This causes additional stress on the plants because they need to repair root damage and adapt to the new micro-environment, all of which can result in wilting.
One other potential cause is ethylene gas, a plant hormone related to ripening. Some fruits and vegetables emit ethylene, especially bananas. Apples, grapes, melons, avocados, and potatoes can also give it off, so keep flowering plants away from fresh produce.

Prevention
Physiological leaf scorch is best avoided by making sure your plants have a healthy, functional root system and access to enough water. Water regularly, especially on the mornings of excessively hot, sunny days. Deep, infrequent irrigation is better than shallow, frequent irrigation.
Have your soil tested and apply the proper nutrients. Be sure to not over-apply fertilizers.
Make sure your plants’ roots have room to expand. Avoid compacted soil as well and avoid paving areas above the root zone. Do not till or disturb the soil where plant roots are growing.
Plant new trees and shrubs in the fall, so that they have the maximum amount of time to become established before the environmental stresses of the next summer.
Remove any dead or dying plant tissue that may harbor secondary infections.
