Solutions: So long as you address waterlogging problems right away, your plant should recover. First, assess the extent of the damage to determine whether it is mild or severe. If the damage is mild, you may only need to reduce your watering levels to revive the plant. Allow the top two inches of soil to dry out between waterings. If the damage is severe: Repot with fresh soil, preferably in a pot with better drainage. If necessary, move plants to places where they get adequate ventilation so the soil can dry out between waterings. Prune away all dead and yellowing leaves. This reduces the plant's water needs and lessens the stress on the roots. It also encourages it to produce new, healthier growth. You should start noticing improvements within a few weeks.

Solutions: As powdery Mildew spores are transported by the wind, it can be tricky to put a complete stop to the spread of the fungus. Luckily, there are several easy treatments for plants that are exhibiting symptoms: If powdery Mildew seems to be impacting isolated leaves or stems, they can simply be trimmed away and disposed of. Disinfect pruning tools after doing this. Remove any plant debris from the ground around the infected plants and dispose of it in the garbage. Then, cover the soil with a thick layer of mulch to limit reinfection. Milk sprays have been found to be useful in controlling powdery Mildew. Make up a spray consisting of 60% water and 40% milk and spray on the affected plants. This can also be used as a preventative measure. In cases where powdery Mildew is more widespread, plants can be sprayed with a mild sulfur- or copper-based fungicide or a non-toxic solution made from baking soda and soap. Sprays can help areas that have been recently infected, though they are less effective against well-established infections. If possible, try transplanting the plants to a sunnier location. Though powdery Mildew does fine in hot, dry conditions, it is unable to reproduce without some humidity. Putting plants in more direct sunlight can help stop the spread of the fungus. Trimming around closely-packed plants can help improve airflow, which also prevents the reproduction of the fungus.

Solutions: Caution: fire ants are venomous and cause painful bites which can be fatal in the case of a rare but significant allergy. Fire ants can be a painful pest to have around for you and your plants. Keeping them under control will ensure comfortable gardening for all. For less severe cases: Physically remove mounds. Dig out and remove entire mounds (remember, they go deeper than they seem). Use citrus oil. Pour citrus oil, which is toxic to fire ants, down their holes. For severe cases: Use ant bait. For a chemical solution, broadcast insecticide bait formulated for fire ants in the area around a mound. Apply the bait during a dry evening so the ants can forage for it at night. Look for products that contain Indoxacarb. Release phorid flies. Introduce or promote beneficial phorid flies to gardens. These parasitic flies attack invasive fire ants. Hire a professional. Some ant baits are only available to professional exterminators. For serious cases of fire ants, consider hiring a professional.

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.
