We recently moved into our house (we are in Houston, Tx) and we have overgrown and numerous dead spots in our Wax Myrtle bushes in our front yard. I am wondering if I can prune them way back to a height I want them? They are in shade. Or should I take them out and replace them?
You can prune them back by about 1/3 per year without killing the plant. That being said, if they are very overgrown, you may find that the interior of the shrub is rather dead from lack of light. Because of this, when you prune them back by 1/3, they may not look very nice. It is worth going ahead and trying to prune them, but be prepared to find that it would look nicer if you just replaced them.
I have a myrtle tree but it does not produce any little white flower. Am I pruning it at the wrong time of year?

12' shrub dying. Leaves turning brown and falling off. 6 yrs. old and irrigated. Two other wax myrtles planted same time in close proximity and look healthy. Have been told it has possible borers.
There are many things that could be wrong with it. Borers are a possibility. This article may be helpful in determining if it is borers:

In general, if you are unable to pinpoint what is wrong, I would recommend treating the plant with neem oil. It is both a fungicide and a pesticide and will treat many issues that could possibly be wrong.
I planted a wax myrtle on east side of a brick wall of my house that gets a lot of sun in the afternoon. Leaves are drying up, limbs getting wilted, and I water it often.
It sounds like it may have a root problem of some kind. I would check the roots for a root rot. This article may be helpful:

Planted 10 wax myrtles 5 years ago and they did well. Suddenly 3 have died completely and others are struggling with some new growth. What can be done to help continued growth?
Is this the common wax myrtle or the dwarf variety? It would help my diagnosis of your problem if you could provide additional information on what is happening to the trees. Anything unusual about the leaves, bark, etc.? Any signs of insect infestations? Has the demise followed some cold harsh weather? Tell me about your care of the tree in terms of watering, fertilizing and pruning.
To help continued growth, I would recommend you follow the guidelines in the following articles:

I have several wax myrtles and two in particular I am growing for privacy and screening. However, they have a habit of flopping over with heavy rain. Last winter they flopped over all the way to the ground when we had a hard frost. I was able to reposition them after the ice melted and after heavy rain they do spring up but this habit is not providing us with a reliable privacy screen that we need. Late last winter I pruned them both back hard in the hopes that they would be more robust but it doesn't appear to have helped. They were both hanging over like weeping willows following a hard rain. So do you think I should stake them, and if so, how? Thanks!
Yes - I would recommend staking your trees to prevent them from flopping over. Here is an article that will guide you on how to stake them:

Happy gardening!
When planting for privacy, how close together should they be?
To grow an unbroken hedge you should space the plants no further apart then their mature spread.
This is usually about 20 to 25 feet.
If each plant reaches 20 feet and spreads 10 feet on either side; two hedges will eventually meet in the middle of a 20 foot spacing.
You can plant closer together--7 to 12 feet without any harm and they will form a more tight hedge.
