Common Rose Diseases

This article will help you identify and treat the most common ailments that might befall your roses. They fall into two categories: insect pests and microbial diseases.

Insects

Some insects are beneficial to your roses, but many like to chow down on the leaves and buds. In most circumstances, it’s best to treat the plants with insecticides only when you see the pests or their effects; otherwise, you can weaken the plant by killing the good insects as well as the bad. The following section discusses how to identify and treat infestations of common rose-attacking insects.

Wisteria

Wisteria is best known for its pea-like blossoms in varying shades of white, rose and lavender. Once established, wisteria is not difficult to maintain. It will survive with average rainfall, and bloom with little to no fertilizer. However, wisteria does need seasonal pruning to ensure spring blooms and compact growing. Otherwise, you could end up with 25 feet of rambling vines and no flowers.


Wisteria is native to the United States, as well as, eastern Asia. The Chinese and Japanese cultivars are most commonly used in landscaping since their blooms are fragrant, unlike the US varieties. Regardless of the variety you choose, follow these guidelines for years of prolific blooms.

Plant Collapse

It is always disappointing when a cherished specimen suddenly looks sickly, and it is so often the more expensive types which succumb first. There is not going to be much pleasure in growing indoor plants unless you learn how to avoid plant troubles.

Specific pests and diseases are not usually to blame; in most cases the cause of illness or death is either too much or too little of one or more of the essential growth factors.

There are scores of possible reasons which can account for the death of an indoor plant. The seven most common fatal factors are:

Ginger – The Multipurpose Herb

Ginger (Family Zingiberaceae) is a perennial herb that thrives in most parts of southern Asia, Jamaica, Nigeria, and the West Indies. The plant has recently been cultivated in Florida, California, and Hawaii. Purple orchid-like flowers grow on the stalks of the wild plant. The most common part of the plant known for its multi-faceted use is the thick tuberous rhizome root that is brown on the outside but a dark yellowish amber hue on the inside.

Ginger yields an essential oil that is steam distilled from the unpeeled, dried and ground root. The scent is somewhat bitterer than the root but when used in aromatherapy the oil mixes well with sandalwood, cedar wood and patchouli, adding a woody-spicy scent to the mix.

Fall Berries

A big display of fall berries provides a striking seasonal note and also adds a range of colors, from bright red to yellow and white. In time most, except the toxic ones, will get eaten by birds. Meantime, as the fall mists descend and then lift, they will reveal beautiful clumps of tiny colored balls high up in the trees and down on the ground, attracting extra wildlife.

The best berrying trees include ash (Sorbus), which provide a range of colored fruit and several specimens that will not grow too high. The slow-growing Sorbus x kewensis only grows 2.5m (8ft) high and 2m (6ft) wide, and its late spring flowers are replaced by bright red berries.

Living Stones

The Living Stones are interesting rather than beautiful, as they mimic the pebbles which abound in their natural habitat. Living Stones are flowering succulents that blend into their native environment because they grow in a stemless clump resembling small stones. All are members of the Mesembryanthemum family and each plant consists of a pair of extremely thick leaves. These are fused together to produce a stem-like body with a slit at the top. This slit may be as small as a tiny hole or it may extend right down to ground level, depending upon the species.

The sizes of the various types available do not differ very much – the range is a height of ½-2 in. Colors and patterns, however, present a bewildering array and collecting a comprehensive range of Living Stones can be a hobby in itself.
