How to Prune Texas Sage (and Why Not to Shear It)
Texas sage is everywhere in Las Cruces, and so are Texas sages sheared into tight green balls with no flowers. Left to its natural shape, it covers itself in purple blooms after summer rain. Here’s when and how to prune Texas sage so it stays tidy and keeps flowering, and how to rescue one that’s overgrown.

Quick answer
When and how should I prune Texas sage?
Prune Texas sage in late winter to mid-spring, before new growth. Thin it by cutting whole branches back to a junction instead of shearing the outside, and remove no more than about a third at once. Leave it alone in late summer and fall so it can bloom.
Texas A&M AgriLife notes that formal shearing reduces flowering. A naturally shaped Texas sage needs pruning only once a year, if that.

Shearing
Why shouldn’t I shear Texas sage into balls?
Shearing cuts off the tips where flowers form, so a sheared Texas sage blooms far less. It also creates a thin shell of leaves over bare, woody stems, and it has to be sheared again and again. Selective thinning keeps the natural shape, more blooms and less work.
What does shearing do?
Every cut tip sprouts several new ones, making a dense outer shell that shades out the inside.
Why do sheared sages go bare inside?
The inner stems get no light, drop their leaves and turn woody, so the shrub looks hollow when cut back.
What’s the better way?
Cut select branches back to a side branch or the base to reduce size while keeping the natural form.
How to prune
How do I prune Texas sage the right way?
Start with dead and damaged branches, then remove the longest or crossing branches back to where they join another branch. Work around the shrub evenly, step back often, and stop when about a third is removed. The result should look natural, not trimmed.
1
Pick the right time
Late winter to mid-spring, before the new flush of growth.
2
Remove dead wood
Cut out dead, broken and crossing branches first.
3
Thin, don’t shear
Follow long branches down to a junction and cut there.
4
Open the center
Remove a few interior stems so light reaches the inside.
5
Stop at a third
Remove no more than about a third of the shrub in a year.
Overgrown
How do I fix an overgrown or leggy Texas sage?
For a shrub that’s too big or bare inside, renew it over two or three springs by removing a third of the oldest stems at the base each year. A healthy sage can also be cut back hard in spring, but it will bloom less that season.
Gradual renewal
Remove a third of the oldest, woodiest stems each spring for three years. The shrub stays full while it resets.
Hard cutback
Cutting a healthy plant back hard in spring works, but expect a bare look and fewer flowers that year.
Wrong spot?
If it’s crowding a walk or window, moving or replacing it with a compact variety may be easier.
Care
How much water does Texas sage need?
Very little once established. Texas sage is drought-tolerant but prone to root rot in soggy soil, so AgriLife advises keeping it high and dry. Water deeply every few weeks in summer on drip, skip fertilizer, and expect blooms to follow rain and humidity.
