Planting Royal Azaleas 철쭉 in Spring

Mr Lee, Hojin and Haein planted flowers for spring but I couldn't help them cause I had to take care Ratana. Weather in early spring is really unpredictable, sometimes it was very warm, sometimes it rained and even snowed. Hmmm..I should say that if you come in May, the weather is still quite cold between 10 to 15 celcius so be prepared with some jacket/cardigan.
