I actually planned to plant 100 trees due to some reason I couldn't, I planted nine trees last year in April,out of nine three had shunted growth with great difficulty I got the solution from them. Now one plant is nearly dieing and other two will also meet the same fate. I come to know that their aim is only sales because of the advertisement I purchased it. It is nothing but cheating. There is no customer service after sales.
