I have long grass growing in and amongst my candytuft. How do I kill it out without killing the candytuft? Or do I just dig it all up and start over? I'm not opposed to chemicals if I need them.
Most grass in garden beds can be easily pulled up (though it may be time consuming) and followed with the addition of a 1/2" thick layer of (moist) newspaper topped with 2" mulch. You can also use a non-selective herbicide, such as glyphosate (Roundup), which has the potential to kill any plant on contact. However, with care this can be used as a spot spray in flower beds, avoiding contact with desirable plants. Don't do this on a windy day. If feasible, you might want to cover your candy tuft with trash bags while you spray, and for about half an hour after. It will dry rather quickly, kill the grass, and will not stay in the soil.
How would Candytuft do in South Texas (Corpus Christi area) during drought condition? I am looking for anything other than traditional mulch--something more natural and less taxing on my hubby's back. Ground cover plants are what I want, but can they handle the heat?

Candy tuft likes good drainage, but it needs watering in dry places; also it needs to be cut back after blooming. Here's an article on good perennials for South Texas; some of them are ground covers: https://bexar-tx.tamu.edu/earth-kind-horticulture/best-plants-for-bexar-county-south-texas/perennial-plants-for-south-texas-landscapes/
I live at the edge of a woods and we so have deer that come close.
I have not seen Candytuft listed as a deer resistant plant.
Here is a link that has some suggestions for plants that are known to be deer resistant.

The cold weather has killed the leaves on my candytuft. How far back should I prune?
You can cut the plant back to nearly the ground.
If you plant has not been pruned regularly I would prune 1/3 now and then another third early in spring prior to leafing out.

My candytuft needs to be cut back so I will do that in the fall, but the flowers are already spent and it's only May. What do I do to get it to keep flowering? I also didn't know they like acidic soil, so I will take care of that.
If you cut the stems back by 1/3 after they bloom in the spring this may encourage a re-bloom come fall.

I bought candytuft plants from a nursery; how deep should the planting hole be?
Dig a hole twice as wide as the container and plant the perennial at the same depth as it was in the nursery pot.
Here is a link with care information.

What is the recommendation on trimming candy tuft. Let it bloom and then trim.. Should this be trimmed low to the ground in the fall. I live in Cincinnati, Ohio. Thx
Yes, this will be fine. This should be done every other year anyways to keep the plant from developing thick, woody stems. This article will give you more information on the care of these: https://www.gardeningknowhow.com/ornamental/flowers/candytuft/growing-candytuft.htm
