Help with sick tree

dgwalker

I just bought a house in December of 2007. There are 3 trees in my backyard that are the same species. In the last two months all the leaves on 1 tree have turned brown and started to fall off. Even the small "baby leaves" that were sprouting from it's branches have turned brown.

I have attatched some links below to pictures of the 1 sick tree and 2 healthy trees.

Does anyone know what type of tree this is?
Does anyone know why it is sick?
What can I do to make the tree better?

Should I cut the tree down so it doesn't get the other trees sick?

Morning, photograhs of flowers and foliage need to be clearer for better identification. Plants appear to be 'semi-advanced' or 'super-advanced' stock material. Check the below ground conditions i.e. plants may be in a 'well' type situation (watelogged).
This is by no means a positive diagnosis of your problem e.g. I could not tell even if the plant was deciduos.

regards

Those look like privets.Pictures of the base of the tree towards the ground will help and pictures of any damage to the tree that is visable[torn bark,broken limbs etc] will help as well.

The pictures appear to be a shrub called red-tipped photinia.

They appear to have been trimmed to a "tree form" rather than the more commonly seen "shrub form."

Disease ridden plants in these parts - I usually advise against planting them.

The dead one in the picture isn't worth treating.

The "healthy ones" are subject to a fungal leaf spot that;s nearly impossible to eradicate.

You'd be better off with different plants.

Looks like Photinia to me as well. They're a pretty hardy shrub round here. You usually find them growing in older more established gardens. I don't think they're as trendy as they use to be. They're usually hedged here but they can grow into a nice bushy shrub or small tree. It looks to me like your tree has just dried out. The first 2 to 3 weeks after planting are critical. Most plant nurseries water their trees at least once or twice a day. Most trees are lucky to be watered once or twice a week when they're planted so it can be a stressful time for them. How you water can also make a difference. I like creating small wells with the back fill. Depending on the time of year, it can take about 6 weeks for the new tree to acclimatise to its new conditions. Too much water can also be a problem. When you water does the water drain away freely or does it pond on the surface? I'm not familiar with the leaf spot fungus problem but if this is the case it might be better to go with some thing else. I would suggest avoiding over head watering and planting them in a warm, sunny, well drained aspect. Why don't you try replacing the dead tree with a new one?
