Question: White Rose Diseases

Good morning.

My white rose has fallen ill: the leaves have begun to fill with holes, they seemed to have been eaten by some animal which, however, could not be seen. So I pruned it, cleaned it up and it looked as if it had recovered, it also hunted 3 new buds but now I see the stained leaves again and some are starting to show some holes again. What does he have ? What do I have to do ?


Answer: White Rose Diseases

Hello Simona, we welcome you to the expert column of our website, the place where gardening enthusiasts can find free advice from plant and gardening experts. Your plant is most likely infested with Oziorinco, a beetle that carries out part of its life cycle in the soil and part of its life cycle on the leaves of the plant. Both in the ground and on the leaves this insect causes enormous damage, certainly dangerous in both cases and above all difficult to identify when the insect is in the ground and cannot be seen.

To eliminate the oziorinco in the larval stage it is necessary to do a geodisinfestant treatment or to treat the soil with special products to eliminate the larvae and thus improve the health of the plant. If, on the other hand, as in his case, the oziorinco is already on the leaves, he will have to use a special product to be applied to the foliage by sprinkling with a spray. To check for the presence of this insect, we advise you to check the leaves at night as this insect is almost always nocturnal.

For more information on products, prices and methods of use, we recommend that you contact your trusted garden center.

Diseases White rose - garden

How to grow flowers and plants in gardens, balconies, in apartments ...

I have never been able to understand if beautiful people have an innate tendency to grow roses or if roses in their growth make people beautiful.”Roland A. Beowne wondered this, I don't know the answer but, if in doubt, I would try to cultivate them.

The Rose is certainly one of the most popular flowers. It is no coincidence that she is considered the queen of the garden. The merit is of its beauty, of the many varieties, of its intense and enveloping perfume, of the extraordinary range of colors, of the charm that has lived and crossed centuries and centuries of history.

Let's go into the wonderful, immense, romantic world of roses.

The Rose, more than any other flower, is part of history. Every genre, every group, every variety has behind it a story to tell, made up of people, work, mixes. We think that the history of the rose as a wild species spans millions of years. The first evidence of its cultivation dates back to five thousand years ago.

But it is in the last 300-400 years that roses have begun to arouse particular interest, which is what these flowers deserve. Hybridization in the history of roses has played a fundamental role: starting from the end of the eighteenth century and throughout the nineteenth century, hybridization works have been almost frenetic and has never been arrested.

Red rose symbol of passion

The numbers speak for themselves: in the last 150 years, over ten thousand cultivars of roses have been created and today about three thousand are grown, selected among the most beautiful, among the most fragrant, among the most robust.

The only drawback seems to be represented by the difficulty of choosing: the range is so vast that it is really difficult to choose. Shrub roses, old roses, modern roses, ground cover roses, tea hybrids. Each has its peculiarities, its characteristics, its cultural needs. For every garden there is its own rose or there are its roses.

Due to the very wide range of varieties it is difficult to describe the Rosa plant.

The Rose is a shrub that is generally erect but which can also be sarmentose, has more or less dark green leaves that have mini-leaflets (from 5 to 11) with simple or double toothed margins, depending on the species. they may have hair.

The flowers of the rose are gathered in inflorescences, they have a number of petals that changes according to the species.

Roses have a stem with thorns, these also change depending on the species.

The fruit of the rose is called rosehip whose size and shape changes depending on the species.

It is therefore the species that makes the difference. And not just the species.


Pest diseases.

Aphids.

Symptoms: presence of green insects on the buds, wilting of the buds, weakening and delay in flowering of the plant, presence of "honeydew", a substance that rejects the aphids, which favors the formation of mold that solidify forming a black crust on the leaves.

Care: it is necessary to obtain a specific pesticide from florists or specialized shops. It is also advisable to wash the leaves with specific soap for plants, available in specialized stores until the encrustations disappear.

Prevention: be very careful when pruning and always use sharp and disinfected tools, taking care to make clean cuts without producing fraying.

Physiological alterations.

Roses can often show signs of suffering not due to insects or molds but only to unsuitable soil and poorly performed cultivation treatments.

Symptoms: yellowing leaves, slow growth, curling leaves.

Causes: too sandy and nitrogen-poor soils, excessive fertilization.

Remedies: repot the plant using different soil and bought in specialized shops.


The Rose Garden is the most beautiful garden in the White House

Renovated by the Kennedys, this is the story of the garden at the center of the news after the intervention of Melania Trump.

When Rachel Lambert Mellon threw a picnic on a sunny August day at her Cape Cod home, she certainly didn't know that afternoon would allow her to make her mark on the history of the most famous mansion in the world. It was 1961 and among the guests, as well as a few friends, there was also the then president of the United States with the First Lady. The two had just returned from France, explains Mellon herself in an official text for the White House Association, and had seen wonderful flower gardens there as in Austria and England. The White House did not have a garden of such splendor and the Kennedys were determined to give one to history as the definitive sign of their passage. The two had in fact understood the symbolic importance of a large and lush garden in an official residence and therefore asked Rachel "Bunny" Mellon, a dear friend of Jackie's, to take care of it.

Arriving at the White House, Mellon was greeted with her friend Perry Wheeler (landscape architect) by the friendly staff of the house: she was ready to go to work. The space to be renovated was that of the Rose Garden, an area of ​​the garden characterized by four rows of privet hedges just over a meter high that ran along the walls of the house and some Tom Thumb roses hidden between one row and another. No trees or plants decorated the area in front of the long porch that connected the Oval Office and the Cabinet Room, except for the ancient magnolia by Andrew Jackson. Mellon had to find a way to harmoniously unite the solid block of the central building and the West Wing with its two long colonnades found inspiration a few months later by observing the wonderful magnolias on the streets of New York.

He would have planted four magnolias in the corners of the Rose Garden to soften the hard edges of the building, he would have sown a lawn large enough to accommodate a thousand people for ceremonies but also small enough to be covered would have been the heart of the garden. On both sides there would then be rows of wild apple trees Katherine, roses and other flowers. The president had found Thomas Jefferson's notes on the garden and wanted to find some of the species planted there in the time of the historic president. Small details such as a higher step from which to make speeches (still widely used today) or a bench under the ancient magnolia were then the special requests of JFK who decided to make the place livable and welcoming. The garden would be divided into sections: along the edges of the designated areas there would be blue tulips and Mùscari in the spring, lavender and geraniums in the summer, and in the autumn it would be time for chrysanthemums, anemone japonica and Michaelmas daisies. With the winter everything would have emptied and only the roses would remain.

The heart of the garden, Mellon always writes, must have remained the roses, undisputed protagonists and never absent in the history of the house. In fact, where the Rose Garden stands today, a wonderful rectangular glass greenhouse once stood, inside which various species of the flower were grown and which gave the place its name. Alongside this, several other greenhouses were dedicated to the cultivation of palms, fruit trees, orchids and camellias. A legacy of the post-civil war period, the greenhouses were later removed by Charles McKim, under the Roosevelt presidency. In their place, the First Lady created the so-called Colonial Garden in 1902, where she grew quinces, sweet peas and plums, as well as the jasmine under which she and President Roosevelt rested on summer evenings.

The Kennedy Garden was completed in 1962 and handed over to White House history. Over the years, First Lady picked up Jackie's and Jack's inheritance to add special touches to the Rose Garden: Mrs Taft added tropical plants in pots, for example. The current First Lady of the United States Melania Trump also spent time working in the garden during her stay. However, its results are much discussed.

In the last few days, very heated controversies have inflamed social media Melania had announced the start of the renovation of the garden at the end of July, in a very controversial period and marked by thousands of deaths from Coronavirus, which meant that the choice was reread as a "Marie Antoinette" act according to a well-known journalist from New York Times. The criticisms concern, beyond the historical moment in which these renovations were carried out, the choice to remove the roses and tulips planted directly by First Lady Jackie Kennedy. As reported Dezeen, the new garden designed by landscape architect Perry Guillot and Oehme, van Sweden & Associates, has been described by many as nothing more than a "piece of lawn of little interest". What remains is the hope that the new First Lady (in November?) Will be able to do better.

It too comes in a woolly form, like a gray felt.

Favored by humidity and hot humid environments.
