How to Diagnose and Prevent Phony Peach Disease Xylella fastidiosa subsp. multiplexWhat could be wrong with an attractive, compact, bushy peach tree? Plenty! Your tree could have the incurable bacterial phony peach disease (PPD).
This disease came seemingly out of nowhere and first struck peach trees in Georgia in 1900. And it had spread all the way to Texas by 1933.
A century later, this pathogen is still a pernicious problem.
No peach tree is safe – every cultivar, form, and hybrid is susceptible.
Your tree won’t die of this affliction, but it will stop producing fruit over a two- to four-year period.

The cause of PPD is a type of bacteria known as Xylella fastidiosa subsp. multiplex. It is closely related to the pathogen that causes the dreaded Pierce’s disease, which has effectively limited the types of grapes that can be grown in the southeast.
Other strains of this species of bacteria can also cause leaf scorch in elm, maple, oak and sycamore trees, or citrus variegated chlorosis in citrus trees.
These bacteria live in the plant’s xylem – the tubes that transport water and nutrients from the roots to the leaves.
And they would stay there if it weren’t for aggressive leafhoppers known as sharpshooters or spittlebugs that suck out the liquid, and become infected in the process.
Unfortunately, these leafhoppers can live on a number of different types of weeds as well as trees, so they are probably residing in close proximity to your peach tree, though this is not typically their number one choice of host.
What can be done at this point? Not much. If your tree is infected, you should remove and destroy it.
However,

The two best complimentary colours are Red and Green. There are many ways this is demonstrated in the spring garden and they will be sure to draw compliments. The Peonies are just opening under a bit of shelter and shade.
Gardeners are observant, and when a favorite plant is struggling, we tend to take notice. Knowing how to respond, however, is another matter entirely. Some folks head to the garden center looking for a cure-all, determined to spray first and ask questions later. But a gardener who invests just a little time to observe the signs and symptoms of a disease can often narrow down which pathogen is affecting the plant and then make an informed decision about what to do next.
Homeowners have had to combat root-knot nematodes for as long as home vegetable gardens have existed. Nematodes are microscopic worms in the soil in high numbers that can cause damage to susceptible plants. Traditionally, the vegetables most affected were beans, watermelons, cucumbers, and especially three grower favorites: tomatoes, sweetpotatoes, and okra. Although there are many types of nematodes in the soil, root-knot nematodes are some of the most common and cause the large galls or knots you see on the roots of susceptible plants
Our names are Jonny and April, and we are from Barnsley in the north of England. We recently moved into a brand-new property with a rectangle of grass for a garden. Over the last five months we have transformed the garden into the beginnings of a tropical paradise, the main feature being the pondless waterfall. Neither of us had ever undertaken a garden project before; however, we have completed all of the work ourselves through the use of YouTube videos and online articles for assistance.
I N A GOOD SPRING, BELOVED PLANTS COME BACK. Not everybody, of course; some just can’t find their way home.
THIS WEEK’S DOODLE IS REALLY A POSTCARD, one to send to the beloved garden in appreciation for a year of its devoted service and joy. Thanks, Andre Jordan, for just the right thing at just the right moment–one less thing on my to-do list, now that you have “send card to garden” covered.
IDIDN’T WASH MY WINDOWS all spring and summer one year, and though I hated looking out through dust and rain splatters and my cat’s many pawprints, it was part of an experiment to see what—if anything—might help reduce the horrible event of window strikes by songbirds, a leading cause of their death.
IT WASN’T ONE OF THOSE “KA-POW!” YEARS in the garden, visually (well, unless you were my dear old rhubarb, above). In fact at many moments it was more “ka-bam!” (as in things crashing and burning, rather than showing off in bursts of glory).
Bill Logan and I talked about how mankind learned to use trees and evolved alongside them with their help; about pruning tactics like pollarding and coppicing; and also how nearly immortal trees are.Read along as you listen to the May 20, 2019 edition of my public-radio show and podcast using the player below.

“What holds the garden together in such a moment?” he asked as we chatted, and as he looked out the window at the scene above.Texture, primarily we agreed. And at Ken’s, especially some refreshing splashes of variegation and definitely the freshness of some white flowers. Using all of those effectively is our topic today, along with some favorite plants (like his Hiba arborvitae or Thujopsis dolobrata, below, a conifer with great texture a
Generally poisonous plants cause harm either by ingestion or touch. Both the phenomena are dangerous especially for people with certain allergy and sensitivity: dermatitis, nausea, vomiting, itchiness are usual symptoms. They can be harmful for pets too, that is why the best option is to remove them securely as soon as you find them in your garden.
