got problems starting a conifer hedge
in september i bought 50 cell grown weston red cedar's to grow a hedge but the problem is every plant has turned a grey.
i'll explain everything what i did when i planted them. i used a bulb digger to dig out all the holes and then i used the same soil and mixed in a little bonemeal and watered every 2 days for a week. 1 week later i watered in some bio bizz fish mix because some of the plants had a little brown on the bottom of them. and now all the plants have tuned grey has anyone got any advice for me or what i should i have done? |

Because a hedge is going to be in situ for many years, it is important to prepare the site properly. A bulb planter doesn't make nearly a big enough hole, nor does it open the surrounding soil texture sufficiently; in fact, it tends to compact it. Your plants had little chance of spreading their roots into the soil beyond their planting hole. You effectively created a sump for water to collect, and I suspect your trees have succumbed to a Phytophthera fungal disease. You need to clear the site of weeds and signicant roots, and dig over the hedge site somewhat wider than required. Have a word with your local garden centre about a fungicide to treat phytophthera. Apply this to the planting site. If this is your idea of a chemical too far, then at least use a mycorhizal treatment as you plant,to give your new trees a good start. *Don't try and use both treatments, as the fungicide will destroy your (usually expensive) mycorhizal treatment*. Create a planting trench in which you can lay out your plants. Use a tree and shrub compost mixed with the excavated soil, ready for infilling the trench around the plants. Water the trench. This will show you if you have created enough drainage. If the water sits a while before draining away, fork over the bottom of the trench. Now put in a layer of the improved soil, plus the mycorhizal treatment. Position your trees, then work back along the trench, straightening the trees as required and backfilling with soil. Water in well. Because you will have improved drainage on the site, you can water regularly without drowning your plants. A dressing of bonemeal is a good idea, but can attract foxes who will dig up your trees:~(. Wait till the trees have clearly 'taken', then try the bonemeal - but check regularly that the foxes haven't disturbed your plants. HTH. -- Spider from high ground in SE London gardening on clay |

Out of interest, why have you chosen western red cedar for a hedge? See comment at end of penultimate paragraph he http://www.ashridgetrees.co.uk/Weste...-Thuja-plicata Several suppliers state that it can be pruned hard and will rejuvenate, but the RHS warns that "All conifers have little or no capacity to regrow from old wood. Over-enthusiastic hedge trimming can result in bare patches." If you want to keep it for your hedge, Spider's advice seems sensible to me. -- Jeff |

Over-enthusiastic hedge trimming can result in bare patches." If you want to keep it for your hedge, Spider's advice seems sensible to me. Our red cedars here were planted over 60 years ago and are now about 40' to 60'' in height. *I don't know what spacing you've been advised to use but eventually, these are big trees with large trunks. *They are not an ideal hedging plant unless you're aiming to blot out something extremely tall close to your property, over a large area. *50 western red cedars are going to turn into a small, straight forest! * I think their roots may have been burned by all the attention they've had, as well as drowned by all the water. *I must ask the question: did you ask the supplier or did the supplier offer you any advice or instructions on after-sales care and attention? And have you gone back to them to ask the above questions? Now that you've spent the money and expended the effort, it's a little sad and late for you to have to turn to strangers for advice on what may well be dead plants. *I'm afraid it may well be too late but our advice to you would be to dig every one of them up right now, put them into a free draining but nourishing compost and let them grow on for two years *at least*. -- Sachawww.hillhousenursery.com South Devon- Hide quoted text - - Show quoted text - Com on Sacha, lets have some lateral thinking. You plant them 9 inches appart, then when the trunks are touching you cut them all down to 6ft and you have a 6ft cedar fence that will last for years. David |
