I. Golden Rules of Flower Cultivation in Shuangyashan

Spraying the leaves twice a week can solve the problem of dryness, and the发财树 needs to maintain a temperature of over 10℃ in winter and control the amount of watering.

Its super long flowering period from March to May, combined with the melting of snow and ice, forms a unique "Rhododendron in Snow" landscape.
2.2 Ecological Value of Sugar Maple Trees
As the city tree, a single sugar maple tree can sequester 68 kilograms of carbon per year. Its unique pinnate leaf vein structure makes the autumn leaf color show a gradient from golden yellow to ochre red, forming a 20-day long colored leaf viewing period.
