Meeti n g w i th you r p eer s i s a good th in g!

This past week, I had the privilege of meeting with horti- culture agents from across the state in Fredericksburg. We had three days filled with excellent talks, tours and field trips; but what I enjoyed the most was the oppor- tunity to sit and talk to other agents to see what is hap- pening in the different parts of the state.

There are some terrific experts in the state and extension is working hard to add the horticultural expertise that is needed. We toured several wineries and vineyards and I was pleasantly surprised to learn that extension has hired new viticulture agents/specialists.

We also had an excellent presentation on fertilizers, where we learned that organic matter is very important when paired with fertilizer, whether organic or store bought. All in all it was an excellent experience and it makes me proud to know that Texas A&M AgriLife is working hard to keep up with the changes occurring in Texas in horticulture.

H o m e m a d e S e l f W a t e r i n g C o n t a i n e r The concept of a self watering planter/bucket has been around for some time and you can find many different vari- ations in many place. The most common process is simply a 5 gallon plastic bucket set in a identical plastic bucket, with specific modifications.

The modifications create a water reserve and wicking so that the container continually provides water to the plant and dramatically reduces the number of times water has to be added. These are most practical when there is not enough room within a standard garden area or when living in a condo or apartment that has only a small yard area or balcony space. Also, if you have a busy schedule the self watering container provides relief from having to consist- ently monitor container soil moisture and add water.

This picture provides a good example of how it works. The easiest process to make one, that I found, was from Baxter County Master Gar- dener Robert Dunston. To see what he created

Howdy y-all,

Well, it’s May and we should all have our gardens planted and even started harvesting some of our vegetables. But for this gardener it looks like I will have to rely on the charity of others for my fresh veggies. I was too late planting and then the neighbors dogs thought they should dig up everything I put in the ground.

As sad as my vegetable garden is, my flower beds are coming along beautifully. Lots of lilies, vines, roses and hibiscus in bloom. Little surprises in every corner. Our house was vacant for over 10 years and much of the landscaping was over grown or non existing. So with a chance to start anew I did what I thought I should do. Bought a book on landscaping, Texas landscaping. Followed all the beautiful pictures to a Tee. Most of it died, but what did survive is strong.

Earlier this spring my front flower beds were all white. Just like clock work every plant that bloomed white bloomed at the same time. Amazing, then all the lilies started blooming. Orange, yellow, purple, blue and lovely greens. I love lilies. I love them because you can ignore them for years and then bam they are back as the star of the yard.

I really do not have a plan for my yard or gardens. I was talking to another Master gardener and I loved her description of her landscaping, she said it w as more of an experiment than a plan. That is an accurate accounting at my house, an experiment. If someone gives me a plant or seeds I will find a spot. These usually turn out to be wonderful blessings.

Right now I have firespikes on my kitchen counter in water hoping to root so I can add some more color around the water garden out back. Really it’s just an old bath tub with water lilies growing in it, but a girl can dream.

Talking about dreaming, we would love to see your gardens. Let’s have some social time and plan on vis- iting with our fellow masters gardeners at home this summer.

Comfrey has been used as an herbal remedy for at least 2000 years. It was once used for a variety of ailments, both internally and externally. Such things as sprains, fractures and bruises were treated with comfrey poultices. It was also used to treat stomach problems. The ingredients in comfrey are no longer recommended for internal use, but might be used as an ointment on skin to reduce swelling and bruising for the short term. It contains allantoin, rosmarinic acid, and tannins. Allantoin is known to help cell growth. Comfrey also contains poisonous chemi- cals called pyrrolizidine alkaloids, which can lead to kidney failure and it’s important to know that those chemicals can be absorbed through the skin.

As a gardener, you might be pleased to know that comfrey has its uses in the garden as a mulch, as a fertilizer and as a compost activator. According to Rodale, the leaves have an N-P-K ratio of 1.8-0.5-5.3. Because it has a long taproot, it can draw upon chemicals, such as calcium, from deep in the soil. It thrives in c lay soil! Should it decline in the heat of our summers, it will return from the deep roots. It may be happier planted in partial shade.

Freshly chopped comfrey leaves can be chopped up and placed in planting holes. The whole leaves can be used as a mulch. If your compost doesn’t heat up, the comfrey leaves can be added with other material as an activator. A diluted compost tea made from the leaves and water can be used as either a foliar spray or a drench. As a spray, it may deter fungus. It is a smelly product, so be forewarned.

More information on the historical uses of comfrey can be found in A Mo dern Herbal by Mrs. M. Grieve , Dover Pub- lishing, first published in 1931. Her writings about specific herbs can be found online. The University of Maryland Medical Center, [ http:/ / umm .edu/ health/m edical/ altm ed/ herb/ com frey ] has an up-to-date view of comfrey.

The Corpus Christi Area Garden Council was formed in the 1940’s by local gardeners with the objective to

conserve native plants and all natural resources, en- courage civic planting, and educate members and the general public in the growing and artistic use of plant material.

The Garden Council wanted to cre- ate a garden headquarter building on City land at Lindale where asso- ciated garden clubs could meet. The City instead suggested a new

building behind the new business zone which was named Cullen Mall. The new garden building was built

at 5325 Greely St., which is just be- hind the Cullen School.

The Garden Council raised the money to finance the

building which was constructed and belonged to the Garden Council. However, after a time the upkeep and other costs of the building became more than

the Garden Council could handle. In November 1963 the building ownership was trans-

The CC Area Garden Council provides the local Gar- den Clubs with a place to meet at no cost, Insurance for local conventions, plant shows and plant sales, financial grants for projects and conventions, a year

book to each Club and a website where they can post their information.

Currently (2016) the following Garden Clubs are members of the Garden Council: CC Bonsai Club, CC Bromeliad Society Inc., Cacti & Succulent Society,

Nueces Master Gardeners, Native Plant Society of Texas (South TX Chapter), Plumeria Society of S. Texas, CC

Rose Society, Bay Area Garden Guild, Ocean Drive Garden Club, Paisano Garden Club, Port

Aransas Garden Club and the Late Bloomers of Portland. Any other garden club can join the

Council for $25 annual dues.

Garden Book that dealt with local conditions was published in 1949. The second was published in 1970

The Renovated Building was renamed as The Garden

Senior Center. It should be noted here that the one person mainly instrumental in all of this is Yvonne

Padilla who has been the heart and soul of gardening in the coastal bend for the last generation.

P o w d e r y M i l d e w o n O r n a m e n t a l s Extracts from this a rticle b y the University o f Califo rnia

Powdery mildew is a common disease on many types of plants and is prevalent under the diverse conditions found in many areas of California (and Texas). Different powdery mildew fungi cause disease on different plants. These fungi tend to infect either plants in the same fami- ly or only one species of plant. I DENTI FICAT I ON AND DAMAG E You can recognize this disease by the white, powdery mycelial and spore growth that forms on leaf surfaces and shoots and sometimes on flow- ers and fruits. Powdery mildews may infect new or old foliage. This disease can be serious on woody species such as rose, crape myrtle, and sycamore where it attacks new growth including buds, shoots, flowers, and leaves. New growth may be dwarfed, dis- torted, and covered with a white, powdery growth. In- fected leaves generally die and drop from the plant earli- er than healthy leaves. LI FE CYCLE All powdery mildew fungi require liv ing plant tissue to grow . On perennial hosts such as roses, powdery mildew survives from one season to the next as vegetative strands in buds or as spherical fruiting bodies, called chasmo thecia, on the bark of branches and stems. Most powdery mildew fungi grow as thin layers o f myce- lium on the surface of the affected plant parts. Spo res, which you can see with a hand lens, are part of the white, powdery appearance of this fungi and are pro- duced in chains on upper or lower leaf surfaces or on flowers, fruits, or herba- ceous stems. In contrast,

vary, all powdery mildew species can germinate and in- fect in the absence of free water. In fact, water on plant surfaces for extended periods inhibits germination and kills the spores of most powdery mildew fungi. Moder- ate temperatures of 60° to 80°F and shady conditions generally are the most favorable for powdery mildew development. Powdery mildew spores and mycelium are sensitive to extreme heat and sunlight, and leaf temper- atures above 95°F may kill the fungus. MAN AGEMENT The best method of control is prevention. Avoiding the most susceptible cultivars, placing plants in full sun, and following good cultural practices will adequately control powdery mildew in many situations. Some ornamentals do require protection with fungicide sprays if mildew conditions are more favorable, especially susceptible varieties of rose and crape myrtle (See Table 1. on web- site). For a list of other common ornamentals suscepti- ble to powdery mildew, (see Table 2 on website). CULTURAL PRACTICES Shade and moderate temperatures favor most powdery mildews. Locate plants in sunny areas as much as possi- ble, provide good air circulation, and avoid excess ferti- lizing or use a slow-release fertilizer. Overhead sprinkling actually may reduce the spread of powdery mildew, be- cause it washes spores off the plant. Also, if spores land in water, they die. The best time to irrigate is mid- morning, so plants dry rapidly, reducing the likelihood of infections by other fungi, such as ones that cause rust or black spot on roses. As new shoots begin to develop on perennial plants, watch closely for signs of powdery mil- dew. FUNGICIDE APPLICATIONS In some situations, especially when growing roses, you may need to use fungicides, which function as protect- ants, eradicants, or both. A protectant fungicide pre- vents new infections from occurring, whereas an eradi- cant can kill an existing infection. Apply protectant fungi- cides to highly susceptible plants before the disease ap-

do wny m ildew, another pears. Use eradicants at the earliest signs of the disease.

fungal disease that produc- es visible powdery growth, has spores that grow on branched stalks and look like tiny trees. Also, downy mil- dew spores occur mostly on the lower leaf surface. Envi- ronmental conditions that favor the growth of downy mildew are different from those that favor powdery mil- dew and include low temperatures of 50° to 70°F, a rela- tive humidity of 90% or higher, and free moisture. Wind carries powdery mildew spores to new hosts. Alt- hough relative humidity requirements for germination

Once mildew growth is extensive, controlling the situa- tion with any fungicide becomes more difficult. FUNGI CI DES Several least-toxic fungicides are available, including horticultural oils, neem oil, jojoba oil, sulfur, potassium bicarbonate, and the biological fungicide Serenade. With the exception of the oils, these materials are primarily preventive, although potassium bicarbonate has some eradicant activity. Oils work best as eradicants but also have some protectant activity.

FUNGI CI DES Several least-toxic fungicides are available, including hor- ticultural oils, neem oil, jojoba oil, sulfur, potassium bi- carbonate, and the biological fungicide Serenade. With the exception of the oils, these materials are primarily preventive, although potassium bicarbonate has some eradicant activity. Oils work best as eradicants but also have some protectant activity. OIL S To eradicate mild to heavy powdery mildew infections, use a horticultural oil such as JMS Stylet Oil, Saf-T-Side Spray Oil, Sunspray Ultra-Fine Spray Oil, or one of the plant-based oils such as neem oil (e.g., Powdery Mildew Killer) or jojoba oil (e.g., E-rase). Be careful, however, never to apply an oil spray within 2 weeks of a sulfur spray, or it may injure plants. Also, you never should ap- ply oils when temperatures are above 90°F or to water- stressed plants. Some plants may be more sensitive than others, and the interval required between sulfur and oil sprays may need to be even longer. Always consult the fungicide label for any special precautions. Of the horti- cultural oils, JMS Stylet Oil is the most highly refined and therefore the least likely to damage plants, but it may be more difficult to obtain than the others. SULFUR Sulfur products have been used to manage powdery mil- dew for centuries but are effective only when applied before the disease appears. The best sulfur products to use for powdery mildew control in gardens are wettable sulfurs that are specially formulated with surfactants similar to those in dishwashing detergent (e.g., Safer Garden Fungicide). However, you shouldn’t use dish- washing detergent with sulfur. Additionally, sulfur can damage some ornamental cultivars. To avoid injuring any plant, do not apply sulfur when the temperature is near

or higher than 90°F, and do not apply it within 2 weeks of an oil spray. Other sulfur products, such as liquid lime sulfur or sulfur dust, are much more difficult to use, irri- tate skin and eyes, and are limited in the types plants you safely can use them on. BICARBONAT ES Also available to licensed applicators only is a fungicide containing potassium bicarbonate (e.g., Kaligreen). Sprays of potassium bicarbonate can injure the plant, so use these products with caution. Biological Fungicides Biological fungicides (e.g., Serenade) are commercially available beneficial microorganisms formulated into a product that, when sprayed on the plant, destroys fungal pathogens. The active ingredient in Serenade is a bacte- rium, Bacillus subtilis, that helps prevent the powdery mildew from infecting the plant. These products have some effect in killing the powdery mildew organism but are not as effective as the oils or sulfur in controlling it. SYN T HETI C FUNGICI DES Myclobutanil (Immunox) also is available to the home gardener and functions as an eradicant and protectant against both powdery mildew and rust. HOW T O USE Apply protectant fungicides to susceptible plants before or in the earliest stages of disease development. Once mildew growth is mild to moderate, it generally is too late for effec- tive control with protectant fungicides. These are effective only on contact, so applications must thoroughly cover all susceptible plant parts. As plants grow and produce new tissue, additional applications may be necessary at 7- to 10- day intervals as long as conditions favor disease growth. If mild to moderate powdery mildew is present, you can use
