Your post lists a litany of mistakes, I am afraid.

1) Amended planting holes (trench)

2) Fertilization (presumably) without sampling soil and having it tested

3) Top pruning at planting time

Too late for 1 and 2, but you can still prevent 3.

In future, skip 1 and 2.

The burlap, nails and ties should come off and out of the hole, too.

Thanks Ron,
Unfortunately, in our area, a certain amount of fill is necessary because of the rocks. For example, in the first 100' of the fence we removed about 5 tons of rocks and boulders. Enough to make a rock wall 3'high and wide, and about about 20' long. Small price for living in paradise I guess.

The burlap came off. We slit the bottoms as they went in and then just pulled up on the burlap. Ours had rope, not the wire cage that would have made it much more difficult.

Personally, I don't consider root stimulator a fertilizer, but I guess it is. The HollyTone is pretty aggressive as well, and for the local conditions, a pretty good idea.

Could you suggest a maintenance program for this plant/hedge? Do you have alot of experience with it? I seems, due to its natural shape, to require very little pruning or shearing.

TIA,

If you can let it grow, then do, because clipping it will be alot more work.

Hi
Yew is slow growing AFTER you cut off the growing tip. Therefore, if you want a hedge, trim the sides (cut them back quite hard the first time to encourage branching), but leave the tops alone until they are at least as tall as you want the hedge to be. Before you cut them they will grow at up to 12' a year. After you cut them, you are lucky if you see 2'.

A mulch of well rotted compost or you know what, about 1' deep every couple of years will keep them happy, and improve the soil as the worms carry it down.

At Ashridge Trees we grow and sell about 10,000 yew a year so hopefully we know what to do with them.

Good luck

In the case of annual growth I suspect you mean inches, not feet. If the mulch is to be a foot deep - not at the trunk, I presume.

I have a 100 foot of hedge. Planted 4 feet apart they are 8 to 10 feet tall, seven years old from seedlings. They have never been pruned. They are starting to lean about 1/2 way up. How do I prune to make the top half stronger, and straight

Just planted 8 hicks yew end of the summer 2010 I have a lot of brown branches now is this a normal happening coming out of a hard winter or do I have some other issues?
