It's been a little while since I entered a photo in Gardening Gone Wild's photo contest. Here's my green pick of the month! I love green, every shade. It's been my favorite color for as long as I can remember. Is it the feeling of peace it brings? Its healing qualities? Its symbolism of nature and life? The feeling of rejuvenation, youth, spring?
Yay for green. And happy Earth Day, coming up soon!
Eve's Necklace, Styphnolobium affine/Sophora affinis, also known as Texas Sophora. I once underappreciated this small native tree growing wild in my sideyard, because as a young and small sapling dominated by the cedar elms above it, it was hard-pressed to grab my attention.
As the small saplings became bigger, however, I began to notice the black string of pearls -- its seed pods -- for which it earned its name.
And its light to dark green leaflets I always dubbed as "cute." I'm so technical.
This spring, however, the pink wisteria-like blooms finally caught my eye, and I have been spending many a morning gazing up at the somewhat wispy understory trees.
With more available sun, I know, it gets much denser and takes on the more classic tree look. It can also eventually reach 30 ft, but my tallest is about 15 feet, and I suspect it will always stay less than 25 feet tall due to its location under the much larger shade trees.
Eve's Necklace loves alkaline soil, of which I have plenty, and it is quite adaptable as long as the earth is well-drained. It's fairly fast-growing and germinates well on its own. It's native to Central Texas and hardy to Zone 7.
The tree has moderate deer resistance, but the deer in my neighborhood have left the saplings alone. It serves as a pollen and nectar source, and when dense enough it's a good nesting and cover site.
There's an advantage to living in a place for years and not doing anything with it -- one is that sometimes you get to find gems like Eve's Necklace coming up naturally. I think that I'll scatter the seeds about to get some growing in other places around my yard. I won't eat them though (not that I would) -- they're poisonous!
EDIT: My husband's response to reading this was "Huh." Turns out he had no idea we had Eve's Necklace in our yard (he'd probably never heard of it either). It's a good thing I write this blog, so he can learn about our yard!Spring is definitely here in Austin, even if the date hasn't officially declared it so. Around town, peach, plum, pear, and dogwood trees are already gorgeously flowering. And buds of other trees and flowers are peeking out to see what's around them, and soon there will be many more blooms and greenery to delight passersby. At home, I'm delighted to see that many of the trees and shrubs we planted in fall and winter made it through the freezes and are beginning to bud.
Goldenball Leadtree:
Chinquapin Oak:
Mexican Redbud:
We even have Salvia blooming. They, along with Gopher Plant and a variety of unknown plants (some might call them weeds), are the first official bloomers of the Great Stems garden.
You can't really count the hanging basket I planted a few days ago. It came with blooms. It's my first real attempt at a container garden -- I need to go check on the names of two of the plants, but the chartreuse one is sweet potato vine. I'll enjoy watching what happens.
Hey, cat -- get off the birdbath!
Lacey Oak:
A plant I put in the ground on a whim during the fall thrived all through the winter despite freezes and snow. It's growing at a very rapid pace, too, and I need to help it climb up instead of out: coral honeysuckle. I think its new growth is very beautiful.
Cat! Get out of that birdbath, too! Gah!
It's a good thing I bought a hanging birdbath on a whim, I guess -- the cat won't be able to use that one! It's a grocery-store purchase, all of $14.95, so cute that I couldn't resist. I added a twig as a perch (not visible in this picture).
Looking out the study window (with the cat safely back inside), I see two birds at the mosaic birdbath and am happy to report that birds have also discovered the new feeder I put out there. Chickadees, finches, cardinals, and titmice so far... I'm taking pictures -- I'll share them in the next day or two.
In the back I've got an overgrown but wildly successful vegetable garden in one bed and weeds taking over the unused beds. Must get out there and get the new garden planted... In another area, I see a strawberry bloom... and wow, there's a broccoli head forming! My first broccoli!
Rogue pumpkins are showing up where I left an old pumpkin out for too long. Now I'm going to have guilt when I pull them up and not let them take over the garden bed again... Maybe I'll just move them to an open spot in the yard and let them shade out the bermuda...
Off in the wooded area, the wild yaupons are producing fantastic new growth.
It looks like we lost two in-ground citrus trees, but the container lime and lemon trees are suddenly growing like crazy. I better give them some yummy organic fertilizer soon. Maybe I'll see our first fruit this year. The two pomegranates we planted bare root are also starting to bud. Yay! Lime tree:
I planted several Rusty Blackhaw Viburnums this fall. Two came from a local reader who was so wonderful to contact me when she needed to thin out some of the babies below her mother tree. These "babies" were much bigger than most of the ones I purchased! I'm happy to report that they survived their transplant and are budding right now.
Another Rusty Blackhaw that I purchased took some damage over the winter, and we thought it might not make it. I saw that its main trunk was split, presumably from dog damage. But I was shocked to discover after having left it in its container as is for a couple of months that it was budding. I quickly got it in the ground, and now look at it:
Incomplete list of trees and shrubs we planted this fall and winter, all budding or leafing:
Lost to freeze and/or dogs:
Jury's still out on:
All in all, that's not a bad record, given the amount of damage my dogs did last year! I see that some of our perennials are coming up (among the weeds that went crazy). I'll start assessing those soon.
Hey, bud. It makes my heart happy to see you!
My husband and I completed an Urban Forest Steward training program this past weekend here in Austin. Going into the first class three months ago, I have to say I really didn't know what to expect. After all, I'd learned so much already about trees, so I thought. But without a doubt, I'm glad that I took the class with my husband, because we learned a tremendous amount. Most of the class was held indoors, but we occasionally ventured out for hands-on demonstrations on pruning, planting, etc.
Here are several of the many facts and tips we learned:
Planting
When planting trees from containers, you really need to look deeper into the soil (pulling the tree out of the container) and look for girdling roots around the stem/trunk and encircling roots around the root mass. There's a method to cutting, but the main thing is that you want to cut girdling and encircling roots and redirect as many roots as you can to radiate out from the center, before you backfill with dirt. Don't be afraid to move aside some dirt to seek out those roots wrapping around the stem and main roots.
Don't amend the soil. This goes against what many old-school methods teach, but when you amend the soil in the planting hole, you discourage roots from venturing into the existing soil, and your roots will start to girdle and strangle each other, trying to stay in the "better soil."
Dig a hole twice as wide and no deeper than the height of the root flare -- it's better to plant high than low -- that root flare of the tree needs to stay visible. Sides of the bowl should be sloping and not smooth like ceramic (typically found when digging in clay soil).
Plant wisely -- learn the height and requirements of a tree before you plant it. Planting large trees under electrical wires or trees in other poor locations only leads to heartache later, not to mention time and money wasted.
Pruning
Every cut is a wound. Only prune when absolutely necessary. Always cut outside the branch collar, not flush against the tree.
There are methods to helping a wound heal better -- not necessarily "sealing" it -- so research this before you harm your tree. One method includes cleaning up the jagged edges of a wound with a sharp knife.
Prune from the outside, NOT from the inside of the canopy -- these inner branches are most critical to the tree's health. In other words, raising the canopy of a tree might be nice for humans, but it is an ill-fated practice in regard to the tree itself. And don't top the tree.
It's best do any pruning and shaping in the first year, and then leave the tree alone as best you can. Prune off suckers and secondary leaders as appropriate for the long-term shape and stability of the tree.
Mulch should extend as wide as the branches of the tree extend -- the root system often extends as far as twice as wide as the canopy of the tree, depending on the species.
Grass and trees don't mix. One affects the health of the other. Grass affects whether the roots of the tree can obtain oxygen and water, and it's the smaller roots farther away from the tree that do this work.
Oak Wilt
Oak wilt spreads via root systems in red oaks and live oaks, but it spreads by fungal spores as well for red oaks. This is why you find major live oak/oak wilt centers with infected trees surrounding them, but it's the red oak that can create the situations to spread out and create new oak wilt centers.
Looking at Trees in the Urban Environment
As a result of this class, our eyes have been opened to the great harm an urban environment causes trees. The way developers place asphalt, sidewalks, curbs, and raised beds shockingly cuts off the root systems of many urban trees, leading to the premature demise of these trees. Damage from lawnmowers and construction vehicles also severely wound trees. And then there's mulch. All around town right now, I'm seeing huge mounds of mulch at the base of trees, smothering the root flare and going several inches up the trunk, and this will lead to weakness and potential rotting of the tree base. Think about the costs involved in dealing with weakening trees, dying trees, and the replacement of once-old and massive trees. Urban development with thought and care might have let those beautiful trees remain healthy and standing for decades to hundreds of years to come.
Graduation and Leaf for a Leaf
After the last class, in conjunction with the Leaf for a Leaf program at the city libraries, we helped plant trees at the Carver Library in Austin. With the planting of about 30 of a variety of trees, we helped turn what was once an open, high maintenance grass lawn into what will one day become a shade-offering "Growth Potential Grove," as the program calls it. Our son got involved and helped.
We really are grateful for the knowledge we gained during this class, which was taught by several different foresters and arborists from Austin Parks and Rec, UT, Austin Urban forestry Board, Texas Forest Service, and other groups. It sure opened our eyes to look at trees in the city, forest, and home environments in a whole new way. And this weekend, we planted five more trees in our own yard. Mmmmm, oxygen.
