Black spot leaf disease shows itself first with black spots appearing on the leaf, then with rings of yellow as the spots grow, until the leaves turn yellow and fall off.Black spot spreads quickly and weakens plants.It's present at all times, even in the deep winter.Proper care can help reduce instances of this disease.
Step 1: Prune leaves quickly.
Remove all the sick leaves from your plant.To prevent the spread of disease through contact with the plant or soil, throw them away immediately with your regular trash.Thoroughly wash your tool after each leaf to prevent the disease from spreading.You can have a solution of 1-part bleach to 4-part water.
Step 2: Treat areas that are sick.
The leaves that have turned yellow are most likely too far gone to recover.Pruning off entire limbs is better if the infection is widespread.The leaves bottoms as well as their tops should be treated.Although there is no guaranteed cure for black spot disease, try the following remedies, which can slow and prevent the disease from spreading, and use whichever shows the best results.Baking soda is 2.5 ounces.A small amount of vegetable oil.1 gallon of water and liquid soap.Liquid soap is not detergent.Before spraying the entire plant, spray a small test area with the solution to make sure it doesn't burn your leaves.If there is no burning, spray the leaves once every two weeks.Combine dairy milk with water.The leaves should be sprayed once a week.Non- dairy milk substitute won't work for vegan.The leaves should be sprayed with the oil every two weeks.If the disease returns multiple times, use fungicides as a last resort.Follow their directions.Since they are preventative in nature, apply them early.If possible, choose organic products for the health of the plant as well as the pollinating insects.
Step 3: Throw away any leaves that are not sterile.
As soon as possible, remove them from the area.Put them in a bag with your garbage.If you dump them into a trashcan, make sure the lid is firmly fastened to prevent the wind or animals from blowing them free.When compost is used as mulch, do not add leaves that have been affected by the disease.
Step 4: Rake constantly.
Keep the base of the plant or tree clear of leaves that may have fallen on their own.Since beds of dead leaves trap and retain water, it is a good idea to clear fallen leaves.If you have to, be sure to rake straight up to winter's first snow, or even after if needed; the disease may survive the cold weather and reinfect the plant or tree when spring comes.
Step 5: The lower canopy needs to be Prune.
Prune from the bottom up.Black spot disease is more likely to be found in the lower leaves.Lower branches that receive sunlight should be Prune back.You won't need to get to those high-up branches if youPruning the lower canopy is also safer.
Step 6: You should water your plant or tree.
Direct water the soil.The leaves should be kept dry.It's a good idea to avoid over watering.Before watering again, allow the soil to dry.Don't water during rainy weather.
Step 7: The air should be circulating.
The soil should be weeded to improve the flow of air.A ring of free space between the mulch and the trunk can be created by applying a level amount of mulch around the base of the plant.Improve the area's ability to dry more thoroughly by preventing weeds from growing.
Step 8: Purchase resistant plants.
If you want to include a tree or plant in your landscape, you need to research it.Do you know if any variety is resistant to the disease?If the cost of resistant varieties is higher than non- resistant ones, ask yourself if you want to save money now or time later.
Step 9: New plants need to be separated from each other.
When planting new plants, picture the size they will reach once fully grown.Allow each to have plenty of distance from the rest in the future.Keeping one plant from touching another will prevent the spread of disease.Eliminate the excessive shade that overcrowded canopies provide by allowing sunlight to reach and dry the lower leaves.mulch around newly planted areasThis will keep the disease out of the leaves when it rains.
Step 10: Plants should not be planted in areas that are overly moist.
Black spot disease can be mitigated by planting in areas that dry quickly after rain.Direct sunlight is available for at least a portion of the day.There are areas that are prone to standing water.If you have lawn sprinklers, make sure they don't soak your leaves.
