Hi Jen, These are my sick palms we talked about from the freeze.  See you in kickboxing class on Wed.

Bernadette

Hey Jen,

Hope all is good with you.

My buddy bought some fox tail palms last year (approx. 20 foot tall) and this winter has them brown.  Will they come back or are the toast?

Let me know please when you get some time to answer.

Tommy

Hi Bernadette and Tommy,

We recommend waiting until March to see if their is any new  “green” growth before you cut the brown frowns and do not cut into the green. 

 Jeff River Law, Houston Xeriscape expert,  says as long as your palms are not leaning over or mooshy they should be fine. 

Grant Stevenson, Houston Palm  and Tropical expert  says if you can pull the frowns out from the top then it is dead.  Horticultural Consultants, Inc. has become a leader in providing Palms, Cycads and Bamboo to professional clients nationwide.

My bird of paradise leaves are brown with green stalks from the snow last year. Should I cut them back to stimulate new growth? If so how far?

Is it time to prune my crepe myrtles?

Paul H., Bellaire, Texas

Hi Paul,

You can do either two things with your bird of paradise:

1. Cut back your bird of paradise halfway and new shoots should start sprouting with the warm temperatures we are having. Just hope that we do not get another freeze this season.  If it  freezes again this season make sure you cover it well.  

2.  Or you can wait until late February to cut them back when their is no chance of a freeze.

Winter is the best and easiest time to prune crepe myrtles because the tree has no leaves and all the energy is in the roots.  It is also the best time to see their branching structure, and the best time to identify and remove limbs that are damaged or that are beginning to rub against one another. However, you can actually prune crape myrtles to remove unwanted branches and basal sprouts year ’round. 

We recommend not topping the crepe myrtle like  I saw today at my daughter’s elementary school.   If you must to control the height it should be done every 7 years and fertilize with tree spikes when you do this.  Topping trees leaves large open wounds that can trigger problems and shorten the specimen’s life span. It results in fists or nubs from which multiple weak branches sprout in the spring. These are fast-growing, but they usually result in unnaturally long branches that are loosely attached and more susceptible to breakage

Please don't Murder

According to the Arbor Day Foundation, “The appearance of a properly pruned tree is like a good haircut: hardly noticeable at first glance.”

Jen,

Aren’t you big into native plants?  How do they fair in a Houston freeze? Jon

Yes, I love the  indigenous plants.  I think all natives did well. During this time of the year they are not blooming so they just look dead.    Interesting you asked Jon,  I was just in the car with my mentor and friend Jeff Law, owner of Indian Summer Lodge and he pulled out a list he has been working on of ”good” plants and  damaged plants from the freeze.    Of course I told him I have to have it so I can share it.

Most everything that was established will come back says Houston Xeriscape expert, Jeff Law.  Remember, most of the hybrids, semi tropicals and tropicals have done well the past 20 years.  Gardeners just have to know which ones will winter, which ones to cover, and which palms not to plant in Houston. Mexican, queen, date, and sabal palms all see fine. foxtail Palms look dead, but we won’t know until it warms up.    Jeff says, he planted some foxtail palms this year, even though he knew they do not like it below freezing much, yet everyone has been planting them the past 5-8 years quite a bit.  Even Queen palms don’t like it this cold, but most seem fine so far.

 The following lists are plants that Jeff has observed at his famous Indian Summer Lodge in the Heights and in other Houston gardens. 

List of  “GOOD” Plants

• silverado sage
• aztec grass
• pampas grass
• gulf Coast Muhly grass
• maiden grass
• cosmopolitan grass
• horsetail
• artemsia
• roses
• blue agaves
• cassias
• loropetalums
• oleanders (standard)
• loquats
• palo verde retama
• nandinas
• privets
• dianella
• sparkler sedge
• holly fern
• polygala
• dianthus
• virgina sweetspire
• cast iron
• bottlebrush tree

 Normal winter flowering plants that DID NOT do well that usually prefer winter

• skyflower vine
• mexican flame vine
• firespike
• cassias
• Van Houti and Indigo spires
• Bolivian Pink Powderpuff
• Hamelia

Some plants that did not like this cold at all. 

• ixora                                                                                                                                          
• heliconias
• persian shields
• plumerias
• birds of paradise
• coleus
• little john bottlebrush- looks burned, but leaves still on
• asparagus fern
• sword fern
• fire spike
• Kolanches look like wilted spinach
• banana
• jatropha
• basil
• sedum
• echeverias
• oleander (dwarf)
• pentas
• variegated ginger (standard)
• Cestrum
• Sweet Memory Duranta
• Almond Verbena
• wandering jews
• succulents
• australian violets
• croton

These plants look dead, but stems still alive so we won’t know until it warms up.  Tropicals can go into shock, or die, but we need 40s-70s this winter to keep them alive now.  Any more deep hard freezing will not be good for anything but for the plants on the first list and of course the “normal apartments“ such as  boxwood, Indian hawthorn, photinias, pittosporum, ilex….

As for bamboo some did great, and some we have to see when it warms up.  There are cold hearty one that can take less than 20 degrees and our heat.  Some of the new types do not take the cold that are sold in commercial nurseries the past few years. 

 Jeff says, he has gardens grow all winter, just depends on the freezes light or heavy, long or short and what time of the winter we get them.  It also depends on where they are planted, along walls or sides of homes to block wind, in the sunlight or in the shade, or what part of Houston.  There are 100 miles north to south to Houston and several different mini zones. Please email me if you can add to the list!

Hey Jen,
Hope all is well. Any suggestions for how to handle the cold?  I think we lost some ixoras
and lantana.  Also, how should we handle the sprinklers?

Thanks and best for 2010!

Hi Jeff and Jamie,

Cover your plants with a sheet or blanket and water in your favorite ones before covering them.  The ground is soggy so I don’t think much water is really needed and do not cover your plants with plastic because they will suffocate.   As for your plants that have damage from last freeze do not clip them back until Spring.  Heidi Sheesley from TreeSearch Farms , who I think very highly of told me a few weeks back that the damage will help protect the tree/plant if we get more freezes this winter.  

As for your spinkler system it should be off this time of the year. If you have new plant material, watering by hand is better. I spoke to my friend Jeff Law, one of the founders of Houston’s Green Movement and a specialist in xeroscaping and we discussed how watering should really not be used unless we have a fall/winter drought.  Wishing you a warm and cozy weekend.

Below is a picture of my parent’s backyard during a New Hampshire blizzard this winter.

Can you tell me what might be eating my Bougainvillea folliage?   

Thank you,

David Vincente

 

David, It sounds like its the bougainvillea looper.   The caterpiller is a green or brown and about 1 inch long.   It feeds primarily at night, which is why you may see the damage but fail to find the culprit on the plant.

The insect will cause significant visual damage to bougainvillea, although this does not apparently result in the death of the plant.

With the cooler weather the loopers will slow down so I recommend nothing. 

If you would like to use something you can spray with Bt or with Spinosad. Neither one lasts very long on the plant after it is sprayed. It probably would be good to spray about 3 times a week apart.

There is an expanding brown patch of grass in the front yard , it started this past week.  Could it be due to all the rain?  Can grass get over-watered?

J&J Weinberg

Hello J and J,

You have Brown Patch which can be very damaging to St. Augustine in the fall.   Brown patch varies in size from 4 inches to 18 inches in diameter.  Brown patch is a disease from hot, humid weather. It is most common when night temperatures and relative humidity stay high for several days and are accompanied by rain.  We treat our jobs with Liquid Systematic Fungicide.  Brown Patch usually occurs in areas that lack good air circulation or have poor drainage. 
This weekend I will be enjoying the weather and going to see some inspiring John Palmer Art in the Heights.   His art is magical!

John Palmer’s Gallery is inviting Houston to a Greek Afternoon and Greek Party that will  help raise funds for the Houston Heights Association’s Heights Boulevard Beautification and Reforestation.

“Dumb Question!     What happens to the St Augustine grass we currently have?  Will it return?”

Yolanda Ramirez

Hi Yolanda,
Not a dumb question….Many of my clients have asked the same question and yes it will return.

Keep in mind that there are two kinds of Rye, both annual and perennial. The difference is in the grasses’ preference of climate. Perennial is perfect for those living in cooler climates with milder summers, while annual will only live for one season and must be replanted in southern states.

The rye seed that JenScapes is applying is an annual which will give you green lawn throughout this fall and winter AND WILL CHOKE OUT YOUR WEEDS..   This Rye grass  we spread will die when the weather becomes hot in late spring.  Just in time for your St. Augustine to come out of dormancy.

Rye grass is what you need to keep your lawn beautiful all year long. The best time to plant for optimum forage production is September and October in fall.

After spreading seed, water lawn immediately, preferably in the late afternoon.  Mow rye grass after it sprouts and enjoy a blanket of thick green grass.

Don’t skimp on the quality of seed.

BE GREEN,

Jen

Hi Jen, What to do what to do. I planted some oleanders last year and they are thriving. I read somewhere that they should be cut back in late August or early September. What is the best way to prune these? I read something about cutting below the three leaves! What and how do you determine that? Lost in my oleanders!!! Please help

Yolanda Ramirez

Hi Yolanda,

Oleanders are evergreen shrubs that can be pruned basically anytime of the year. The best time is when they are not in bloom.  Cut back to desired height and let the spring flush it with new growth and produce the desired look.  Some say the oleander is pruned after blooming and should be pruned by the end of August or early September to give any new growth sufficient time to harden off before winter. Houston has very mild winters so this probably doesn’t matter as much. I would only prune your oleanders if you think they are just overgrown and ugly otherwise little pruning is required to maintain their natural shape.A rule of thumb is not to prune more than a third of the existing foliage and to carefully prune stems so that removal is evenly distributed for a balanced look.

By cutting back just above the leaf nodes of the Oleander it will make your shrub very full.   This is the section where three leaves come out of the branch. By cutting it here, you will be forcing new branching at each of the leaf nodes (joints). Three new branches will grow from the section that once had three leaves. By doing this, it will increase the branch threefold.

One thing to note: all parts of oleanders are highly poisonous. I usually wear long sleeves and gloves to prune mine back. Even the woody parts are poisonous, so don’t go putting your hand in your mouth.

Hey Jen,

Do you know what the little clear dots are on my Papaya?  And do you know when the fruit will be ready for harvest?

Jules, Houston, Texas

   

Hi Jules,

I think the oozing from the Papaya are sugars produced by the plant. It is probably a normal phenomenon caused by heat, humidity or some other climactic pressure.

Heidi Sheesley from TreeSearch Farms said that the fruit would begin to turn yellow then (she does not have experience this is an assumption) it could be harvested and ripened inside like an avocado.
