Expert Answer

Pure neem oil can be sprayed until close to harvest time. Be sure to wash all produce well if you have sprayed recently.

Question

How can I get rid of black spots on roses?

Community Answer

Mix together 5 litres of water, 2 tsp of BiCarb soda, a few drops of detergent and seaweed extract. This is an eco-friendly and affordable fungal spray. First, remove all the diseased leaves...then spray.

Question

My large chamaeron plant has black spots. What can I do to get rid of them?

Community Answer

The leaf spot disease is actually a fungal disease. If you don't do something on time, your whole plant will be affected and it may even damage the soil and you won't be able to grow any more plants in that soil, so you need to use fungicide. It is easily available in the market.

Question

How do I save my fig tree that has black spot leaf disease?

Mary Ellen Sweeney

Community Answer

My fig has black spot on a few leaves as well, since we have had a good deal of rain and mine is in a pot. I've removed the three affected leaves, sprayed with Dawn liquid detergent dilution and have added dry soil to the pot. I popped a few more holes in the bottom of the pot for drainage, and plan to cover the soil when rain is forecast. So far, so good. No new black spots. I've been cultivating this fig tree (in a big pot) for 6 or 7 years. It's a Chicago Hardy, and it has given me a couple of edible figs to date. This year, it has full sun and is growing to beat the band. Best year yet.
