Irrigation SNAFU

You can’t pick your neighbors.  

A pithy statement, to be sure.  While it might be true, another saying I’d like to introduce–Friends don’t let friends over water–also appeals to me.  I don’t live in a neighborhood that is particularly, um, progressive in the realm of home gardening. Especially for  a neighborhood in a region which is experiencing severe drought conditions.  Each of the mostly sterile, water-wasting landscapes throughout my neighborhood showcases a blank slate of water-guzzling St. Augustine lawn as the major “garden” feature and many are situated in full Texas sun. These properties require loads of mowing, edging, fertilizing, and irrigating.

There are a couple of folks who understand the value of home gardening and landscaping as a low-maintenance, water-conserving, perennial and wildlife friendly endeavor, but not many.

And I don’t live next door to either of those folks.

This is the result of over watering a Soft-leaf Yucca,Yucca recurvifolia, compliments of a neighbor who is an enthusiastic St. Augustine lawn waterer.

Beginning in early August, this poor thing developed spots on its straps, which quickly spread, rendering each strap a mottled mess, which then died.  I couldn’t figure out what the cause of the diseased foliage was, but I pruned the disfigured and dying foliage, strap by strap.

IMGP0516_cropped_2562x2759..new

Damage from an insect infestation?  I searched and couldn’t find any offenders. Some sort of disease of Soft-leaf Yucca?    Always a possibility, though literature doesn’t suggest this species has any real disease problems.  Additionally,  I have eight other Soft-leaf Yucca plants thriving in my gardens, from full sun,

IMGP1199_cropped_4415x3142..new

…to deep shade,

IMGP3042.new

…and everything in between.

IMGP0519_cropped_3318x4221..new

IMGP0874.new

There were and are no disease issues with any of those other yuccas.   The only variable with the sickly yucca that differed from the others was the weekly irrigation courtesy of  the neighbor.  I don’t water often–primarily my gardens are watered only with rain.  I pruned the mottled and dead foliage in hopes of stopping the necrosis and eventually the yucca sported a tree-like shape which was fun and quirky. I thought the yucca might survive.

IMGP1047.new

 

One morning though, I  found a rotted and toppled-over yucca.IMGP1752_cropped_3622x3410..new

Yuck-ah.

IMGP1753.new

Well, there wasn’t much I could do, except to cut my losses, or rather, the yucca, toss the mess into the yard waste can and stand there, hands on hips mulling my next step.  I considered digging up the whole root, but alas, the yucca root is too large for that.  Of course it is.  It’s a xeric plant and its xeric-ness comes from the massive root system, really a type of rhizome, that the mature plant develops.  Also, there were pups growing,

IMGP1754.new

…and rather than disturb them, I left the yucca root in place with its new, seemingly healthy growth.

My neighbor, Mr. I-Gotta-Water-Every-Week-No-Matter-What, watered his St. Augustine grass.  Every week!  You could set your clock by his schedule. I couldn’t really complain because he watered on his assigned day, during the accepted hours, and though more water than necessary ran down the curb, it wasn’t horrible. Trust me, I’ve seen worse.   What I didn’t realize during those months was that the yucca was probably watered every week. I never thought to check if his overhead sprinkler was watering my garden, which borders his property.  Because of its massive root, the yucca doesn’t require much irrigation.  Once I connected the rotted yucca with weekly summer irrigation, I realized the cause of the once-healthy yucca’s demise. The hardy Soft-leaf Yucca had received much too much water for its needs.

I should add that Y. recurvifolia is not native to Texas, but to the Southeastern part of the U.S.  I doesn’t mind a little irrigation from time-to-time, but certainly doesn’t like wet feet or require regular watering.

That’s why I plant what I plant–so that I don’t need to water often.  There are many benefits to using native and well-adapted, drought-tolerant plants in a home garden, and conserving water is certainly at or near the top of that list. But the prevalence of St. Augustine grass, especially in full sun and as a primary landscape feature, is not a regionally appropriate choice for Texas.  To look good, it requires more water than should be wasted on a landscape.

I left the little pups that were emerging,IMGP3038.new

…and they’ve grown.  I’ll talk to my neighbor next summer to explain why I don’t want extra water on my garden.  With our lakes (the prime water source for Austin and surrounding areas) down to about 30% capacity and heading toward a historic low, he might not be able to water anyway because of tighter water restrictions.

His grass will struggle with those restrictions, but my gardens will continue to blossom and boom.

IMGP0861.new

And my yuccas and other xeric plants, will be happy.

Foliage Follow-Up, November 2014: The Non-Freeze

My gardens are slowing down in preparation for winter, but haven’t experience the frosty nip that was promised earlier in the week. Thank goodness!  I’m not quite ready to give in to the dark season.  Not Just Yet.

Focusing on mid-November foliage, I’m joining with Pam at Digging for Foliage Follow-Up.

In one corner of my garden with dappled light most of the day and some direct sun off and on, are a couple of favorite foliage vignettes.  One such is of Iris straps, Blue MistflowerConoclinium coelestinum,  and cobalt-blue containerized succulent Ghost Plant, Graptopetalum paraguayense.

IMGP1798.new

Planted alongside that mix are several  Dianella or Variegated Flax Lily, Dianella tasmanica ‘Variegata’. IMGP1865.new

I love the wide, grass-like foliage of Dianella with its snazzy white stripes down the sides.IMGP2017.new

When a freeze was predicted this week, I covered the Dianella, though my concerns were unwarranted.  Last winter, I covered all of my Dianella each time the temperature sank into the ’20s, especially for extended periods. They soldiered through winter like the garden champs they are and thrived in our long, hot summer. Dianella nicely combine with Iris and Soft-leaf Yucca straps,IMGP1864.new

…as well as with these snuggly Love-Critters.

IMGP1862.new

Ghost Plant is unkillable:  it goes for months without water, isn’t fazed by freezes (or at least mine haven’t been), can re-grow if a stem is broken.

IMGP2642.new

My kinda plant.

Maiden GrassMiscanthus sinensis ‘Adagio’ is in its glory now.IMGP1868.new

The beautiful seed heads reflect the sun as it briefly peeked through our mostly cloudy week.

Toasty-seeded Inland Sea OatsChasmanthium latifolium and the green swath of Cast Iron Plant,  Aspidistra elatior are a striking pair.

IMGP1881.new

Added to this scene is Purple HeartSetcreasea pallida, which dramatizes that story a bit.

IMGP1882.new

Big MuhlyMuhlenbergia lindheimeri and Soft-leaf YuccaYucca recurvifolia  are cool weather troopers.IMGP2399.new

Graceful while also lending structure to the garden, these two are beautiful companions throughout the year, hot or cold.

IMGP2518.new

I took this photo of  evergreen Yarrow, Achillea millefolium and Chile Pequin, Capsicum annuum var. glabriusculum,  just before what was supposed to be a freezing night.  I figured the fruits wouldn’t survive the plunging temperatures and wanted to record them for posterity.IMGP2529.new

I’m happy to report that the fruits are still available for dining by interested birds.

I love the twisty-curvy foliage of Corkscrew RushJuncus effusus spiralis, silhouetted over a pair of Mexican FeathergrassNassella tenuissima.

IMGP1875.new

Finally, the leaf change is beginning on my Red Oak, Quercus coccinea.

IMGP2641.new Here in Central Texas, our tree foliage color change occurs later than that of our northern kin, but beautiful and appropriate for our climate and region. There will be more of this in the weeks to come.

Digging hosts Foliage Follow-Up–drop in for a look at November foliage fanfare.

Foliage Follow-up, September 2014

As with our blooms, the Central Texas foliage perks up with September rains, shorter days, and the suggestion of cooler temperature ahead.  I join with Pam at Digging to celebrate the end of summer, new beginnings for autumn, and all things leafy.

The pond garden is a riot of fascinating foliage.  Just take a look! P1070046.new

Lots of foliage action in this shot!  Clockwise from the bottom, the actual water plants include the lily pads of the two lilies I grow (Colorado and Claude Ikins), the Ruby Red Runner, and the showy leaves of the Pickerel RushPontederia cordata.   All three pond plants contribute to the biological filtration of my pond, though I also have a mechanical filter.

Continuing with the tour d’ foliage, the plants adjacent to the pond include tropical Yellow Bells, Tecoma stans, Soft-leaf Yucca, Yucca recurvifolia, Firecracker Plant, Russelia equisetiformis, Martha Gonzales Roses, Iris, Autumn Sage, Salvia greggii, and Mexican Feathergrass, Nassella tenuissima.  All of these perennials sport differing widths, textures, and colors of leaves.

P1070034.new

Ruby Red Runner dies back in the winter, but by late summer into fall it’s full-on lovely and spreading.

P1070042.new

 

P1070035.new

It’s seeded out in several places around the pond. This plant, usually used as a waterfall biological filter and prized for its attractive foliage, produces teensy puff-ball flowers,

IMGP0402_cropped_3073x3308..new

…which go to seed, thus, the spread.

Another view of the plants near the pond…

20140914_19.new

Not much blooming in those photos, but a variety of leaf beauty.

I particularly like these water shots with the creeping roots of the Ruby Red Runner, spreading its spidery fingers toward the lily pads,

P1070057.new

P1070056.new

…as if the roots are creeping outward to grab the pads.  Or maybe they’re just reaching out for a watery hug!

The soft, elegant foliage of Lindheimer’s Senna, Senna lindheimeriana,

20140914_11.new

lends structure to, but also softens the back of my garden.  Combined with the bright green leaves of the Yellow Bells and spiky, but matching-in-color American Century Plant, Agave americana,

P1070358.new

…the Senna fits well in this spot.

The morning after a recent rain,  the foliage of the Purple Heart, Setcreasea pallida, retained droplets along its edges.

20140914_54.new

With “traditional” autumn coloring, (which doesn’t happen for Central Texas on a large-scale until late November/December), the plumes of the Maiden Grass, Miscanthus sinensis ‘Adagio’, beautifully complement the flowers of Turk’s CapMalvaviscus arboreus, and the orange blossoms of Flame Acanthus, Anisacanthus quadrifidus var. wrightii.

P1070133.new

Here’s a closer look at the inflorescence of the Maiden Grass.IMGP0268.new

Along with the orange-y and autumn-y color theme, this new ceramic container is planted with the ‘Color Guard’ YuccaYucca filamentosa ‘Color Guard’, accompanied by Woolly Stemodia, Stemodia lanata.

The container sits amidst a nest of blooming and berrying Pigeonberry, Rivina humilis.
