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 fall off.Black spot spreads quickly and weakens plants if left unattended.It's present at all times, even deep winter.Proper care can help reduce instances of this disease.
Step 1: Prune leaves quickly.
Remove all the leaves that are sick from your plant.To prevent the spread of disease through contact with the plant or soil, throw them away immediately with your trash.Thoroughly wash your tool after each leaf to prevent the disease from spreading.You can get a solution of 1-part bleach to 4-part water.
Step 2: Treat areas that have been bitten.
These leaves are most likely too far gone to recover and should be Prune them.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.There is liquid soap and water.Liquid soap is not detergent.Before spraying the entire plant, spray a small test area with the solution.If there is no burning, spray the leaves every two weeks.Combine dairy milk with water.You can spray the leaves 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 for multiple growing seasons, use fungicides as a last resort.Follow their instructions.They are preventative in nature and should be applied early.If possible, choose organic products for the health of the plant and pollinating insects.
Step 3: Throw away any leaves that are not sterile.
As soon as you can, remove them from the area.They should be put in a bag with your regular garbage.If you dump them in 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 continually.
The base of the plant or tree should be kept 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, because the disease may survive the cold weather and reinfect the plant or tree when spring comes.
Step 5: Take care of the lower canopy.
It is best to cut from the bottom up.Black spot disease is more likely to be found in the lower leaves.Lower branches that never completely dry should be Prune back.You won't need to get to the high-up branches if youPruning the lower canopy is also safer.
Step 6: Water your tree or plant well.
You should water the soil directly.The leaves should be kept dry.It's a good idea to avoid overwatering.Before watering, allow the soil to dry.Don't water during the 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 plants that are resistant.
Determine the type of tree or plant you want to include in your landscape.Do you know if any variety has been proven to be 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 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 them 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 areasWhen it rains, this will absorb water and keep the disease out of the leaves.
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.For at least a portion of the day, choose spots that receive direct sunlight.Don't go to areas that are prone to standing water.If you have lawn sprinklers, adjust them so they don't soak your leaves.
