Solutions: There are several easy ways to remedy the nutrient deficiencies in soils. Use a water-soluble fertilizer. Fertilizers will include most or all of the macro and micro-nutrients the plants need to thrive. Adding some fertilizer to the soil will make those nutrients available and can combat deficiencies. Regularly apply organic fertilizer pellets. Organic fertilizers such as animal manures and bonemeal can supply plants with all the nutrients that they need to grow strong and healthy. Apply compost. Though not as finely tuned as artificial fertilizer, compost can nevertheless be rich in important nutrients and should be applied to the soil regularly. Apply nutrients via foliar application. In addition to supplementing the soil with nutrients, foliar fertilizer can be applied directly to the plant's leaves. Nutrients offered via foliar application are often taken up even quicker than those put in the soil, so the foliar application can be great for swiftly addressing specific deficiencies.

Solutions: Diseases Fungicides can prevent the transmission of spores, but they may not treat the established infection. The first step is removing and disposing of all infected plant parts. Then apply recommended chemicals. For bacterial infections, apply a spray containing copper or streptomycin. For fungal infections, consult the local cooperative extension for recommendations on which fungicides will work best. Nutrient deficiency Apply a liquid fertilizer via foliar application to fix the deficiency quickly. Follow label directions regarding dosing instructions and application notes, such as not using before the rain or when temperatures are out of the recommended range. Incorrect watering Determine the water requirements for your specific plant, and follow accordingly. Some plants like consistently moist soil, and others like the soil to dry out slightly before being watered. Pests Thoroughly apply an insecticidal soap, an organic product like neem oil, or an appropriate chemical insecticide to the plant.

Solutions: Leaf Weevils are relatively easy to control once their presence is discovered. Here’s what to do: Spray the foliage with an insecticide Place sticky traps around the lower trunks of fruit trees and other woody plants. Weevils can’t fly, and have to crawl up the plants when they emerge from the soil. Dig into the soil around plants with a garden fork and remove and dispose of any larvae. Let chickens roam around the garden, as they love to feed on weevil larvae.

Solutions: For less serious cases when only a few leaves are affected, complete the following: Prune affected leaves. Using pruning shears, remove leaves that have spots. Dispose of these leaves to avoid spreading the disease to other plants. Clear debris. To stop the spread of disease, remove debris and weeds from around plants. For serious cases when many leaves are infected with large splotches: Apply a fungicide. Fungicides won't cure current infections, but they will prevent anthracnose from spreading to uninfected tissue. Apply a fungicide before a dry period following product instructions. Products containing copper diammonia diacetate are most likely to be effective.
