| DEAR BRENDA: When we
were at the beach recently, I saw, and (I'm ashamed to admit)
dug up a beautiful purple flower out of the lagoon near our
rented beachhouse. A friend said it is a water hyacinth and
that it's a very invasive plant. Wouldn't it be okay tho if I
just planted it in my water garden? I won't put it in any
public place. S.J.
DEAR S.J.: I am doing my very best not
to SCREAM at you. I am going to very calmly explain that this
plant is to Texas what kudzu is to the Southern States. You
have heard of kudzu? Like kudzu this plant is crowding out
native plants, ruining habitats, endangering wildlife,
threatening water supplies for communities, damaging
equipment...need I go on? It quickly covers the surface of
every body of water it enters.
It is a native of Brazil, but spread
just by folks doing what you did, bringing it into nonnative
environments. We aren't the only ones. It's doing far more
harm in Africa than it is here.
The seed can be spread by birds and
wind as well as by water and root growth, so just keeping it
in your little garden won't work. One of the biggest mysteries
to me is how we gardeners insist on seeing our little gardens
as universes unto themselves and refuse to see how we impact
the greater environment around us.
I'm sorry to be ugly about this. But
ignorance is the reason this plant is doing so much damage.
Burn the thing, the whole thing. Now!
DEAR BRENDA: What do you think of
the plant called Thyrallis? It is a yellow-blooming shrub. I
Google-searched it and it seems like it might be okay for this
area. The only thing is that I am looking for something that
will be mostly in the shade and I am afraid this won't bloom.
How about hostas? I have always stayed away from them because
of the snail/slug problem. A.J.
Dear AJ: My thryallis is in partial
shade and blooms beautifully. Actually, it just gets a little
morning sun. Not only that, our four pointers stomped it into
the ground and I thought it was dead for sure. There was not a
leaf left on it. Durn if that thing isn't coming back out
strong.
They also take full sun, but by all
means, if the only place you have to put it is in shade, give
it a try. I love it. I noticed a bank on San Felipe is using
it in planter boxes in full hot sun and it is gorgeous. The
big thing
is: don't overwater. These are drought
tolerant plants which means they need to be planted high so
their roots don't stay wet in our rainy periods.
Re: hostas, I'm not sure what
varieties I have, but they are beautiful too right now. They
were in deep shade for years and years and did really well.
Then we lost a tree and now they're in
full hot sun. I can't see any difference in their blooming. I
don't know why I don't have a slug/snail problem. But I don't.
I think maybe it's a number of factors:
• I have such a huge variety of
things, no more than one or two plants or clumps of any other
thing together.
• That means I have
probably huge beneficial insect population. I don't know.
• I don't treat for
anything -- ever. If bugs take a plant away, well, so be it. I
try something different. But this also means I never kill off
beneficials along with the harmful insects.
Also I don't water them enough. Maybe
it's too dry there for slugs and snails!
The only place I have snail problems
is in my house! They come in my sliding glass door at night
and leave silvery trails on the carpet.
DEAR BRENDA: I have recently (1
month ago) planted 6 tibochinas at our ranch near San Antonio.
It is an alkaline soil and the climate is hot and dry. I have
been watering the plants often but the leaves have all turned
wilty with brown edges curling upwards. The flowers have
fallen off and no more are present. Could you please advise
what I need to do to save them. I have not given them any
Miracle Grow or anything for that matter. I was waiting for
them to get over their transplanting shock but they have
gotten worse. J.
DEAR J. These tropical trees have done
very well here along the Gulf Coast in recent years because of
our mild winters. In a normal winter here (a week of very cold
freezing weather), I suspect they'd all die. But they do like
our humid, very poorly draining soil with very heavy spring
and fall rains which is a lot like their native Brazil. They
actually prefer a slightly acidic soil, so here the
recommendation is to use a good pine needle/oak leaf and/or
pine bark mulch to counter our normally alkaline soil.
So I can see why they might object to
the climate around San Antonio.
However, you say they've only been
planted about a month? Trees traditionally set strong root
systems before they do anything above ground. I wouldn't panic
for at least a full year.
You should have removed all the
flowers and cut the stalks back about 1/3 when you planted.
Flowering, and even supporting existing buds, takes a lot of
plant strength away from root formation. That should be your
first focus.
Cut off all buds and pinch back the
branches just slightly. You don't want to prune too much
because that will force new topgrowth and you don't want that
right now.
You may be overwatering as well.
Curled wilted leaves are a sign of overwatering (and
underwatering). Are they well mulched? That could be more
important than anything in that area.
Leave off the Miracle Gro and
fertilizers right now. Again, these just trigger topgrowth. If
you feel you must try something, get some SuperThrive at the
nursery and water that in. It's not a fertilizer, just a great
root stimulator, and don't use more than recommended. More is
not better.
Then be patient. If they work, they'll
be well worth it.
I'm stretching it a bit to recommend
planting advice for that area, which is so different from our
little subtropical pocket here in Houston. A great resource
for you would be the Texas A&M website
(http://aggie-horticulture.tamu.edu/extension)
which is really geared more for the rest of the state than it
is for us here in Houston.
Hope this helps
DEAR BRENDA: I have some plant that
are growing way larger than they were supposed to. Why don't
they come up with something you can put on a plant tomake it
stop growing so large? M.L.
DEAR M.L.: Growers use manipulative
growth hormones all the time to . In Amsterdam we saw
oleanders and hibiscus only one foot high covered with regular
size blooms. All the result of growth manipulation to keep
plants smaller.
But this is done only to 1. make
shipping easier and 2. entice us to buy the plant. We want
plants covered with blooms, but nurseries can't manage full
size plants.
I did have to smile at your question.
Most of the queries I get want to know how to make plants
grow, not to make them stop growing.
One reason we're all having a problem
with overgrowth is global warming ...
IF that's what's responsible for our
very warm winters here along the Gulf Coast. Plants that
normally grow for 10 months out of the year (our usual growing
season) are now growing 12 months a
year with no let-up and no dieback. Even if it's cold to us
outside, the ground hasn't gotten cold enough to stop root
growth in many years. Only the most tropical of plants
probably even notice winter is here. Mildly tropical plants
are now perennials for us.
You have two choices:
1. Remove those plants and get
something for that space that is genetically programmed to
grow smaller.
2. Prune off unwanted growth.
It's really not a good idea to do any
serious pruning now, especially if you plant to leave on
vacation. Pruning a plant during its growing season triggers
more growth. True the growth will be internal, that is, the
plant will send out more side branches making for a fuller,
prettier plant. But this new growth will also require more
water.
Having said that, tho, I just got
through whacking my porterweed in half.
It's so huge I can't stand it.
My theory is that you should do what
you want to do in the garden when the spirit moves. In my
case, the spirit may never move again. If the plants can't
take it, then they don't belong in my garden!
DEAR BRENDA: I hate this time of
year. Nothing looks good in the garden. What do you do
in your garden in the summer to keep it looking good? I'm in
uptown Houston. A.L.
DEAR A.L.: Your questions frustrates
me almost as much as S. J.'s did. We have so many beautiful
plants that can be totally ignored in our gardens in the
summertime. We insist onignoring these flowers and insist on
planting all kinds of stuff that is totally inappropriate for
Houston summers. Then we complain when everything dies.
Okay, here's what's blooming in my
yard right now. I have watered maybe twice since the first of
May. We've been out of town off and on, so they are on their
own. If they die with this kind of treatment, they don't
belong in my garden. I'm writing this on June 16: Father's
Day!
In the front yard now, in bloom are a
pink oleander, a fire engine-red Knockout rose, blue and white
plumbago, yellow and orange bulbine, a deep red Martha
Gonzales rose, the aforementioned coral porterweed, a pink
Nearly Wild rose, a white Texas swamp lily (crinum), a white
althaea, a pink LaMarne rose and, to my utter amazment, the
mock orange (Philadelphus or English dogwood). It should have
stopped blooming long ago. The cashmere bouquet is also
blooming, but I don't recommend this plant unless you've got a
huge area where an invasive plant would be welcome. Oh, and
some daylilies and Mexican zinnias and Mexican petunias (ruellia).
In the back and side yard, there are
flowers on the coral fountain plant (a russellia), also Red
Rocket russellia, yellow esperanza (Tecoma stans or yellow
bells), pentas, lots of cosmos I planted back in the spring,
barlaria, the last strands of cape jasmine (the only kind of
gardenia I can get to grow in my swampy, slightly alkaline
soil), Katy Road Pink rose, some white rose (all the
aforementioned roses are antiques), hostas, cestrum, lanceleaf
coneflowers, swamp sunflowers, four o'clocks, shell ginger,
turk's cap, crape myrtles (oh, and there are some weeping
crepe blooming in front too), hymenocallis, purple oxalis,
pomgranate, shrimps, purple passionvine, begonias, a
spectacular rangoon creeper. I've probably forgotten some, but
don't tell me that nothing will bloom in your garden in the
summer. All of these except for the cape jasmine will go
through to December if I'm lucky. And pretty soon the
firespike will be beautiful with it's fire engine red spikes.
And it's a shade lover too!
And in July, the lion's tail and
tickseed sunflowers will burst into bloom.
Now, lest you imagine that my yard is
solid color, don't. I have maybe one of each of these plants,
except for the firespike and tickseed and plumbago. I have
lots of those. So these are just spots of color all over.
Still, they are in bloom and it is blasting hot and I haven't
watered much at all.
But then, maybe that's one reason they
do keep going. I haven't pampered them. I am not big on
watering systems. I don't have one. When something looks
really wilted, I may water it. But I don't water things that
aren't wilted.
Most of these plants are very drought
tolerant, which means overwatering will stop them from
blooming and may even kill them. You really do need to get to
know your plants!
If some of these plants aren't
familiar to you, try this:
Log onto: www.google.com.
Type in the name of the plant.
If you want to see more photos, click
on image before you type in the name.
But, before you take any growing or
planting advice off the internet, look to see where it's from.
A full sun plant in Connecticut may need afternoon shade here.
If it says “well-drained,” it mean put it in a well-raised
bed here, perhaps a foot off the ground.

IF YOU ENJOY BRENDA'S
COLUMNS, YOU'LL LOVE HER GARDENING BOOKS — available online
at www.urbanharvest.com.
FROM THE LAZY GARDENER •
• “The Lazy Gardener's
Guide” — revised and updated! First published 10 years
ago, The Guide is described by Brenda as “a gardening book
in calendar format … so you don't have to think!” Based on
her humorous-yet-informative Houston Chronicle calendar, The
Guide details what gardeners should be doing in the garden
each month, provides garden designs (using the hardiest plants
for our climate) for butterflies, hummingbirds, sun, shade and
a variety of other typical suburban situations. Filled with
funny and touching anecdotes from decades of covering
gardening in the Greater Houston/Galveston area. As the
daughter of a BOI, many of these involve Galveston sites and
people!
• GARDENING WITH DOGS.
Co-authored with Frances Burke Goodman, this little booklet
offers tips, landscape plans, good plants for dog-challenged
areas and lots of fun insights into why dogs do what they do
(and how you might just unknowingly be encouraging “bad”
behaviors!)
Look for all these River Bend
Company books at your neighborhood nursery this fall or online
