it may also be that the branches are too thin to keep themselves upright.

==>> i wouldnt expect such.. 2 years after planting .. i would have thought they would have settled by now ... [see below re: too much nitro]

i wonder about how good of stock you bought.. perhaps you favored height over a well proportioned plant??? .. speculating for next time ...

you dont mention sun ... are these plants in full sun.. or is the house blocking it???

yes.. it could it have been planted crooked.. but again.. the plant.. thru its own growth.. should take care of that ... usually by growing larger away from a structure .. because there is more light out that way ....

i would get rid of the grass.. in at least a 3 or 4 foot circle... and properly mulch them .. more for aesthetics than any other reason ... in other words.. it will look better.. to my eye .... and i might go as far as making a whole bed along there.. and put some other plants in there.. as the mulch circles will make a mowing nightmare .... and i hate weedwhips.. so make a bed to avoid such ...

yes.. they can be pruned into a more favorable long term form ... but i hope you avoid

CM murder.. just chopping them off at the top ... maybe you can find some guidance by watching a few of these vids: https://duckduckgo.com/?q=crepe+myrtle+pruning&t=ffcm&iax=videos&ia=videos

but in pruning.. understand ... its a multi year project ... done properly ... with shrubs in general .. the term is: rejuvenation pruning ... and its a lifetime job ... but not a big deal ... once you get comfortable with it ...

it does not surprise me.. that a huge flower show.. makes limbs bend ...

btw.. i just noticed how lush your grass is.. if you are heavily ferting the lawn ... then you might be over ferting the CM ... most shrubs simply dont need all that much fert.. especially lawn fert.. which has too much nitrogen for most plants... other than grass ... this is another reason for a bed ...

What is the best time to prune CM tree. Mine has gotten so tall that I don’t see its blooms. Too many wordy branches , over grown.

Prune when it’s dormant and after the chance of frost. We prune ours in mid January.

We are in California, no danger of frost here. I have several overgrown trees like acorn Oak tree, elderberry tree, crepe mrtyle
Etc. I wonder when can I prune then.

Ruchi, we are in California too; Sacramento. We do get frost and hard freezes in the winter. Typically, trees are pruned when they are dormant in the winter.

Crapes can be pruned any time of year.

While you can prune any tree at any time, that does not mean it is the best time to do so :-) Virtually any temperate climate tree will respond well to dormant or winter pruning....crapes are no different. Pruning at other times of year can result in growth that is more vulnerable to drought stress or cold.

There are some exceptions but I would not include crape myrtles among them.

25+ yrs experience having too many Crapes to count ... they’re fine pruned any time of year. Doesn’t harm them in any way whatsoever. :-)

I prefer doing it while they’re leafed out so that I can see what most needs pruning/shaping (such as limbing up, cutting shoots off trunks if needed, etc). I do smaller, interior limbs when they’ve lost their leaves (easier to see them then).

Jinx, when best to do this will be highly dependent on location. In milder winter climates you might get away with doing this any time you want. In colder climates, pruning too late in the growing season (but before dormancy) could be the kiss of death.
