I planted about thirty emerald cedars around the backyard about two months ago - they are about 5 feet high and most are doing well. I dug large holes and put in rich topsoil at base and around the soil that came with each plant - I have been watering every second day and have given them a boost of Miraclegrow. But about two weeks ago I noticed that some of the top tips are browning and some browning is happening is the middle lower areas - what should I do to stop or reverse this ? About half of them are doing fine and they are totally green.
burning can be from too much water (root decoomposition), poor drainage, too litle water and fertilizer burn amongst other things. whats the native soil like outside of the topsoil filled holes? does it allow reasonable drainage?how much water are you giving them every two days?
I have a soaker hose - I leave on for 3 hours - I was told by many people ( including dad ) that cedars need lots of water. The native soil is pretty good ( farmers fields for many years prior ) I live in southern Ontario.
Check near roots for excess moisture, you may be drowning them. Having different material inside planting holes from that which is around them likely to contribute to this, water tending to collect in holes because texture inside holes different. Same reason water collects in sumps.
I am suffering from the same thing. I think that I am drowning my ceder hedge. Would stopping my watering program for a week or two help to bring back the bright green color to the tree? Troy
