Albanian pasque-flower
Pulsatilla albana
Albanian pasque-flower are herbaceous plants noted for their silky flowers, fern-like foliage, and easy care. They are also completely covered in silky hairs, which is why they're sometimes called "prairie smoke." Several species of albanian pasque-flowers are important symbols for various localities, including Manitoba, Canada; South Dakota, USA; and Oppland, Norway. Be wary, as these plants are toxic and should not be consumed.

Underwatering
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.



Fruit mold
Fungal infections can cause mold to grow on the surface of the fruit and may also cause decay.
Solutions: There are some relatively easy steps to stop the spread of fruit mold, but swift action must be taken. Prune away infected fruits or flowers. As soon as lesions or fuzz are seen, cut away the infected parts and dispose of them. Do not compost. Apply fungicide to plants with mild infections (those with severe infections may need to be destroyed). Increase airflow. Since spores are mainly wind born, increasing the airflow around your plants will make them less susceptible to infection. Maintain maximum space between plants and open branch structures during the pruning season.



Petal blight
Bacterial infections can cause flowers to become soft and rotten.
Solutions: Like other fungal diseases, the progression of petal blight is extremely difficult to stop and impossible to reverse once it infects a plant. The best course of action is to remove all damaged flowers immediately and dispose of them entirely. Do not put them in the compost pile, where spores could grow and spread.

Underwatering
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.

Fruit mold
Fungal infections can cause mold to grow on the surface of the fruit and may also cause decay.

Overview
Fruit mold is the result of fungal infection by one or more of a wide variety of fungal species. Favoring damp and cool conditions, this problem can have a devastating effect on most fruit crops as it tends to occur just when fruit are reaching maturity. Once mold establishes itself, the fruit quickly decays and becomes inedible. The fungus is capable of spreading quickly to other fruit, either or the same plant or on neighboring plants.

Symptom Analysis
Symptoms tend to be obvious but are quick to develop.
- Brown lesions form on the fruit and occasionally the blossoms. These lesions become soft, mushy, and develop a fuzzy gray or brown coating.
- The infection will very quickly spread to any fruit in contact with those that are infected.
- Fruit may drop or remain on the plant and mummify over time.
- Infection may spread to leaves and new branches, eventually leading to demise of the entire plant .

Disease Cause
This condition is caused by one of a number of fungal species which all follow a similar cycle. Spores remain dormant on dead plant material over the winter months and then emerge during the spring when they are carried by the wind or insect vectors to the host plant. Once they land on a plant, often facilitated by damp conditions, the spores will gain entry and breed (sporulate) rapidly. Entry to the plant is often through damage caused by sap-sucking insects.

Solutions
There are some relatively easy steps to stop the spread of fruit mold, but swift action must be taken.
- Prune away infected fruits or flowers. As soon as lesions or fuzz are seen, cut away the infected parts and dispose of them. Do not compost.
- Apply fungicide to plants with mild infections (those with severe infections may need to be destroyed).
- Increase airflow. Since spores are mainly wind born, increasing the airflow around your plants will make them less susceptible to infection. Maintain maximum space between plants and open branch structures during the pruning season.

Prevention
There are easy, preventative steps the gardener can take to stop mold from attacking fruits and fruit-bearing plants:
- Rake up rotting debris when the growing season is over. Fungi can overwinter on rotting debris and reinfect plants the following season. Clear the ground beneath fruit trees and remove hanging mummified fruit.
- Prune off any infected branches.
- Burn all infected debris.
- Preemptively apply fungicide to susceptible plants, especially in the spring. This can help prevent infections from progressing to a stage where fruits are affected.
- Don't overcrowd when planting. Overcrowding will reduce air circulation, leaving plants wetter for longer and increasing the chance of infection.
- Use drip irrigation instead of overhead irrigation. This will help keep plant surfaces free of moisture, while still ensuring roots are getting enough water. Hose-watering should be performed early in the day, with the spray directed at the base of plants.
- Don't over-fertilize early in the spring. Added nutrients will increase leaf size. As leaves can hold moisture and provide a surface for spores to adhere to, this can increase the chance that mold grows on the plant. Fertilizing later in the season, when fruits are ripening, means additional nutrients will be directed towards those fruits, rather than leaves.
- Insect prevention measures will reduce wounds on plants and decrease access points for fungal spores.

Petal blight
Bacterial infections can cause flowers to become soft and rotten.

Overview
Petal blight, sometimes called flower blight, is a fungal disease that only affects the blooms of some ornamental flowering plants. As the infection progresses, it destroys the flower, yet it never damages the vegetative or green parts of the plant.
When flowers are infected, the symptoms look similar to Botrytis blight, but Botrytis also infects dead or dormant vegetative tissue.
The disease was first discovered in Japanese plants in 1919 and in the US in the late 1930s. Presently it is also found in New Zealand, Australia, and parts of Europe. Unfortunately, no plants have high resistance to petal blight, but specific cultivars are more susceptible than others, particularly species with double blooms.
Petal blight infection rates are high when temperatures are mild to warm (optimum temperatures are 15 to 21 ℃) and the weather is misty or rainy.
Overall, petal blight is an aesthetic problem that ruins blossoms. The disease is not harmful to the long-term health of the plant.

Symptom Analysis
The severity of the symptoms varies, depending upon the species of plant infected. Signs of petal blight are commonly seen on the blooms just after they open.
- Pallid spots on colored petals.
- Brown spots on white petals.
- Browning around the petal edges.
- Small spots look water-soaked.
- Spots rapidly enlarge and merge.
- Flowers become limp.
- The entire flower turns light brown, but does not crumble.
- Flowers become slimy at first and then take on a leathery texture.
- A ring of white or gray mycelium can be seen at the base of the petals.

Disease Cause
Petal blight is caused by several different fungi, with each type infecting specific plants. Ovulinia azalea infects azaleas species and cultivars, and rhododendrons. Ciborinia camelliae infects camellia cultivars.
Shortly after blooming, the fungus infects the base of the flowers by the calyx. The fungus produces cell wall-degrading enzymes that destroy flowers within a couple of days. When the flowers fall to the ground, the fungus' hard fruiting bodies fall to the soil as well, overwintering until the following spring.
When temperatures hit the optimum range the following season, spores are transmitted by insects or can spread on wind currents up to about 12 miles. Once in the soil, the pathogen can be active for three to five years.

Solutions
Like other fungal diseases, the progression of petal blight is extremely difficult to stop and impossible to reverse once it infects a plant. The best course of action is to remove all damaged flowers immediately and dispose of them entirely. Do not put them in the compost pile, where spores could grow and spread.

Prevention
- Apply a preventative dose of fungicide as soon as blooms start to show color on the plant. The preventative can be applied as a soil drench or directly to the flowers on the plant.
- Avoid overhead watering during blooming.
- Remove any leaf litter and dead flowers at the end of the season.
- Cover the ground under infected plants with 4” of fresh organic mulch before winter, taking care not to disturb the infected soil.
- Buy bare-root specimens when available.
- When potted plants are purchased, remove the top layer of potting soil and replace it with fresh mulch.
- Plant cultivars that bloom early in the season before the temperatures get high enough for petal blight pathogens to be spreading.
