Old-man's-beard

Year-round

Old-man's-beard is a fast, heavy climbing vine that wants a sturdy structure and steady moisture, and like all Clematis it is not good for pets to chew on.

• Give it full sun to part shade. In Lubbock's hot, dry summers a little afternoon shade helps it hold up.
• Water regularly through the growing season. This vine likes more consistent moisture than a typical tough native and will sulk if the root zone dries out completely.
• It adapts to almost any soil, sandy, loamy, rocky, or heavy clay, as long as it drains and doesn't stay soggy.
• This vine can put on 10 to 15 feet of growth in a single season, so give it its own sturdy trellis, arbor, or fence to climb before it takes off.
• Clematis as a group is not good for dogs, cats, or horses to chew on or eat. It can irritate the mouth and stomach and cause drooling, vomiting, or diarrhea.

Give it its own trellis or fence from day one. Left untrained, this fast grower can climb onto a shared fence line, so staying HOA-conscious here just means keeping it on your own structure.

Fall

Fall is a second good planting window, and the plant starts winding down toward dormancy as the weather cools.

• Fall, after the worst heat breaks but before Lubbock's average first frost around November 11, is a second good window to plant this vine.
• As days shorten and cool, growth slows and the plant heads into dormancy. Ease off watering as that happens.
• The fuzzy white seed plumes that give this vine its old-man's-beard look show up now and often stick around into winter.

The seed plumes can look shaggy on a front-facing or shared fence line by late fall. Trim them back if a neater look matters there, though they're fine to leave for winter interest and for birds.

Winter

Winter is dormant season and the time for the vine's big yearly cutback, before new growth starts up again in spring.

• Anytime from late December through February, before new growth starts, cut all the stems back hard to about 12 to 24 inches above the ground.
• This hard yearly cutback keeps the vine from turning into a tangled mess and helps it bloom well again the following summer.
• When you cut the old woody stems, they may weep a clear fluid. That's normal and nothing to worry about.
• Established plants are hardy through Lubbock's zone 7b winters and don't need extra protection, but a layer of mulch over the root zone helps a newly planted vine through its first winter.

The late-winter hard cutback is also your best yearly chance to keep this fast climber off a neighbor's fence before spring growth takes off again.

Spring

Spring is planting season once the frost risk passes, and this is when the vine's fast regrowth really kicks off after a winter cutback.

• Lubbock's average last frost is around March 24, with mid-April a safer bet in a cooler year. Hold off on new plantings until after that.
• Once it warms up, growth takes off fast. This vine can add 10 to 15 feet in a single season.
• A late cold snap can nip tender new shoots, but established plants usually bounce back and push new growth again.
• This is a good time to check that the trellis, arbor, or fence is sturdy enough before the season's growth spurt starts.

Summer

Summer is bloom season, and it lands right in the middle of Lubbock's hottest, driest stretch, so watering matters more than usual.

• Main bloom runs from around July into September, right through the hottest part of the year here.
• Keep up regular watering through summer. This species wants steadier moisture than a typical drought-tough native and will show stress if it dries out.
• Lubbock summers bring intense heat and wind on top of zone 7 conditions, so afternoon shade or a deep, less frequent watering schedule helps it cope.
• Wilting leaves during the worst 100 degree stretches usually point to a water problem rather than a pest problem.
