How much is the greening of the sales office about a square meter, here in Jinan, Shandong?

Hello, the cost of greening needs to be comprehensively calculated according to the specific varieties, specifications and quality of seedlings for greening. The same variety specifications are divided into high quality, medium quality and inferior quality. Most of the sales offices use high-quality seedlings for greening, and the varieties use better greening seedlings, such as Magnolia grandiflora, Ligustrum lucidum, Osmanthus fragrans, Zelkova schneideriana and Pu Shu. The hedges are heather, Ligustrum lucidum, Buxus macrophylla and Buxus macrophylla. The modeling ball can be heather ball, privet ball, boneless ball, boxwood ball, etc. And the lawns are mostly sijiqing and guolingcao. According to my years of working experience in the company, the cost of an area of about 200 square meters is estimated at about 30 thousand yuan. It depends on the variety, specifications and greening effect of the seedlings required by the boss, and then make the final offer.
