Talking about the experience of domestic rhododendron
I have cultivated cuckoos for more than ten years, and now I would like to write down some of my experiences for your reference. Potted rhododendron can be divided into four types: spring rhododendron, summer rhododendron, western cuckoo and rhododendron, all of which require acidic soil with a pH value of 4.5 to 5.5 (rhododendron slightly wider, but not more than 6.5). If alkaline soil is used, it will surely die. It can be mixed with garden soil, rotten sawdust, charcoal dust, rotten cake powder, bone meal, etc., according to the ratio of 10 ∶ 2 ∶ 3 ∶ 0.5 ∶ 0.5 (volume ratio) to make a pH value of about 5.
