I planted golden bamboo last winter and in the spring it was looking good and sending up new shoots. Now it has really bushed out and again new shoots coming up BUT now it has started to turn yellow. At first it was just old leaves; now it is new ones also. It is very hot here. I have been giving it organic fertilizer and recently put old manure and some compost on the soil. The soil it is in is soil that drains well. I don’t know if it is coincidence but the leaves started to turn yellow more after I put the manure around the plants. However, this is when the really hot weather arrived too. Please can you give me some advice? I have been watering it every day and just yesterday gave it more fertilizer and a good soaking.
You should not try to fertilize during hot weather as this can lead to root burning, which results in the yellowing you are seeing. I would try to flush out some of the excess fertilizer by hosing down the area for about 10-15 minutes or so.
