We bought 6 cedars at the end of June this year and planted them along the fence in order to start creating a hedge along that fence. The plants are in full sun and get at least 6 hours of sun during summer. We kept watering them every 2-3 days and made sure the trunk is not burried. The grond slopes underneath the fence right behind them so I would think there should be no drainage issues. We bought them from a farm and replanted them in a few hours in the same day. We haven't added any fertilizer -we just used the local soil. After 1 month or so, they started to develop brown patches here an there - see pictures. Any idea what may be wrong with them ? Are these patches normal just because of the summer ? I intend to plant about 30 more cedars but now I'm worried about them dying.... Any advice would be highly appreciated.
