Why Are Redcurrant Leaves Suddenly Turning Yellow And Falling Off

Question

Over the last two weeks my redcurrant bush started yellowing very rapidly. I started after I fed it sulphur of iron to lower the soils ph. Could be a coincidence? The ph isn’t very low anyway it seems. I added some soft fruit feed a few days ago but no improvement still.

Answer 1

Under or over watering is often the reason for yellow leaves so check that point. Also, since it started with the application of iron sulfate, I suspect that caused the yellowing. Possibly too much was used and it burned the plants.

Did you do a soil test before trying to lower the pH? That is always advisable before trying to change it.
