YOU ASKED: 

What's wrong with my
Sago Palm?

Sago Palms are very unusual plants and cause lots of concern in the gardening community. When everything seems to be going well, they suddenly exhibit something that we've not seen before. Here is one customer inquiry that had several of us stumped: 

I stopped by the nursery today to inquire what might be wrong with one of my Sagos [click on link to view photo] located by our swimming pool. They suggested that I email you for advice because they have never seen anything like it before. As far as I know, no chemicals have been used on or around it. We did have the lawn service place some mulch in late April. We have several more Sagos in the backyard and they all look healthy. Can you help me?

I surfed the web and found a link to a page with similar photos (I've included the link below). You might go and read about the problems in those photos and decide if you think that these photos and the customer's photo could be related. I think that a combination of nutrition, pH and culture might be the problem with our customer. Here is what the Texas A&M Plant Disease Diagnostic laboratory said about the photo when I sent it to them:

"In my opinion, these symptoms do not really suggest infectious disease. It looks like this plant has experienced an "episode" of something that has stressed/damaged tissue at a certain stage of maturity or development. It appears that oldest and youngest tissue is not affected or minimally affected. It is difficult to say what this might be...I tend to think NOT anything infectious, but more physiological or cultural...or even chemical (drift, exposure, etc). I can't rule out some type of nutritional stress but nutritional stress generally develops slowly over time...so aspects of time of progression of occurrence would be important here. I would ask if anything had been sprayed in the general vicinity prior to symptom development.

"At this point in time, I see no reason to apply any type of fungicide... unless additional evaluation and/or symptom suggest fungal problems."

Poisonous Walking Stick

 Fact or Myth?

Got a message lately about a foreign species of walking stick insect that has invaded Texas and spits acid into your eyes, causing pain and possible blindness? Here are the facts (you'll have to put up with a couple of ads from this site, but it's a great site to debunk possible urban myths and clarify other stories that might be true).

And if you'd like to see the insects in question without going to the site, here are a couple of links:

Celebrate Safely

Whether you celebrate Hanukkah, Christmas, Kwanzaa, New Year's, Thanksgiving, Halloween or all of the above, the year-end holiday season is a time to enjoy. But as it coincides with colder temperatures and heating season, we need to exercise additional caution to have a safe Holiday Season.

Have your heating units checked and cleaned early. Keep space heaters away from anything that can burn and keep fireplace fires small and covered with a screen.

When you give a party, use chafing dishes with caution, provide smokers with non-tip ashtrays, and keep an eye on anyone who is drinking and smoking.

Mixing children with matches and lighters, like for New Year's celebrations or lighting Holiday candles can be a dangerous situation. Teach older children how to light the candles and fireplaces and keep all matches and lighters out of children's reach.

Be sure that you use indoor lighting that has been tested by an independent laboratory, throw away any sets of lights with frayed or cracked cords, and don't overload your electrical outlets. Extinguish all candles before retiring at night and never burn candles near a Christmas tree or decorations or displays.

And if you have a fresh-cut Christmas tree, check it daily and keep it well watered. If you have an artificial tree make sure that it's flame-retardant.

Enjoy this Holiday Season and many more.

Fall & Winter Plants

I thought it might be fun to list the plants that are showy right now and give you a little clue to the suitability of each for the season. So I strolled through the garden center just now and jotted down a few plants that "popped" out. If you'd like this kind of information more regularly than what I'm sending now, maybe we could do a really short note, maybe just in Text format, and send that to you. If you have any input you'd like to share, just write and tell us.

Blooming Right Now

Celosia - the popular Feather type of Celosia has been absolutely gorgeous. There are also some of the Cockscomb type in mixed containers and singly. Annual; great for Fall and Spring, not winter hardy; give full sun.

Mums - This is THE season for mums, both garden-type and fancy, party mums. Perennial but treated mostly as annual; great for now and re-bloom in the spring.

Cassia - Both Splendens and Corymbosa are blooming right now, bright yellow bonnet-type flowers on upright, shrubby plants. Perennial; bloom now, deciduous in winter, give full sun.

Marigolds - Beautiful right now but not great for colder temperatures. Annual, see them again in the Spring.

Petunias - One of the world's most popular plants is hardy to the 20s. Full sun.

Bougainvillea - Tropicals that are in bloom right now and that contrast strikingly with Fall colors; Best for Summer gardens, will need Winter protection. Full sun.

Geraniums - Most people don't realize that these are hardy into the 20s during the Winter. Bloom nicely in the Fall, grow all Winter then explode in the Spring with blooms. Full sun.

Crossandra - Orange & peach colored blooms right now and through the spring and summer. Great for mild weather but will need frost protection. Remove spent blossoms like the ones in the photo and treat as an annual, semi-shade.

Ornamental Peppers - The most beautiful crops ever, multi-colored peppers on bushy plants, great for Fall Decorating. Annual, but you can carry them through the Winter with protection. They'll produce again next year. Full sun.

Snapdragons - Winter hardy to the lower 20s, choose from tall "rocket" types or "border" types. Full sun and will bloom all Winter and next Spring.

Pansies & Violas - THE favorite Winter bedding plants. Very hardy, bloom all Winter and into next Spring. Full sun best.

Dianthus & Carnations - Extremely Winter-hardy, produce flowers during the coldest Houston weather. Great complement to Pansies. Full sun best.

Bulbine - More is visible in streetside and median plantings these days. Yellow or golden spikes of blooms on plants that look like green onions. Very Winter-hardy and perennial. Full sun.

Cuphea - Several varieties including the Mexican Heather and the taller, "cigar" types like 'David Verity'. Taller varieties have more prominent flowers. Perennial, Semi-shade to full sun.

Hamelia - Firebush or Hummingbird Bush, it's blooming right now and will repeat in the spring if protected through the winter. If not, then it will usually die down to the ground and return from the soil, blooming by Summer. Full sun.

Colorful Plants Right Now

Crotons - One of the most Fall-looking plants around. Leaves are multi-colored with reds, oranges, peaches, yellows, greens and almost black, ideal for Fall decorating. Tropical and will require Winter protection. Best for Summer and Fall patios, full sun.

Japanese Maples - Not the ordinary plant for Houston, but rapidly becoming popular. Right now they are beginning to turn colors for Fall, the Lace-leaf types are best looking. Great for specimen areas or large containers for accents. Semi-shade is best.

Grasses - Many ornamental grasses are showing their Fall colors right now. One of the most striking is the 'Purple Majesty' Ornamental Millet. Black-burgundy leaves on tall plants that produce golden spikes of seeds that birds love.

Polka-Dot Plants - Also called Pink Splash, these plants can become perennial in the protected garden. Leaves speckled in rose, pink or red, and an occasional white variety. Can be kept small with pinching, and are ideal for container combinations.
