Tips for Pruning Roses

Pruning rose bushes doesn't have to be difficult or intimidating. Rose bushes need to be pruned in a special way, so make pruning more efficient with these tested tips.

Roses have a reputation of being difficult to grow—as long as you feed them and prune them correctly, you shouldn't have too much trouble with these pretty plants. Pruning is a vital element of rose plant care and the longevity of the plant in your garden. In general, you will be pruning rose bushes just before the plant breaks dormancy after spring's final frost. This will be early in the year in warm climates, and anytime between January and April in cold climates.

If it's old roses you are tending, prune them after blooming. They bear flowers on last year's wood. When rose pruning, cut away the dead wood first—it will help you "see" the shape of the plant without distraction. It's a good idea to visit a public rose garden and find specimens of roses you are growing. Note how the gardeners have pruned roses of the same type.

In cold-winter climates, pruning roses in spring is often reduced to one option: Simply cut back the wood that was killed in winter. In warm climates, pruning can be done at any of three levels, depending on your purpose. Severe pruning (cut to leave three or four canes, 6 to 10 inches high) produces fewer but larger blooms. Moderate pruning (five to 12 canes cut to 18 to 24 inches) makes for a larger bush. And light pruning (less than one-third of the plant is thinned out) increases the number of short-stemmed flowers that will be produced.

Diagnosing the Problem

Since brown leaf tips can be caused by any number of factors, begin by considering the least serious causes first, typically environmental or culture problems. Compare how you care for the plant, such as over- or underwatering or what kind of light conditions you provide, with what kind of care the plant actually needs. Check the plant's tag if you still have it or look up your plant online or in a gardening book to see what it requires. Then, if all the conditions are OK, examine the plant carefully for insects or disease.


Presence of Spines or Thorns

The spines or thorns are spread all over the branches, which is an adaptation of the trees growing in arid and hot climate. It grows best under hot tropical climatic condition. The spines provide protection against animals and discourage herbivores from feeding on it.

Poisonous Alkaloid in Leaves

The acacia tree has some unique adaptations to protect itself from animals. One such adaptation is the poisonous alkaloid that the tree pumps into the leaves. This discourages the animals from eating the leaves. It also releases a chemical that prompts other acacia trees nearby to produce the same alkaloid.

Fire Resistance

Fire is a common problem in the dry Savannah areas where the acacia trees are found. In case of a fire, only the parts of the tree above the ground are damaged. Later, it can resprout from the root crown.

Symbiotic Association with Ants

One interesting fact is its symbiotic association with ants. This is mostly observed in the plant species growing in Central America (e.g Acacia sphaerocephala) and Africa. The large hollow stipules having thorn-like structure provide shelter to a numerous species of ants. The ants protect the trees from the attack of herbivores while it derives nutrition from the sap secreted from the stalk of the leaves.

Benefits and Usefulness

The tree has multiple benefits to human beings. It is an ornamental tree, which is also used in the perfume industry. Silver wattle is grown as ornamental plant in the garden. The plant has bright yellow flowers with silvery leaves. This plant is often confused with mimosa, which also has yellow-colored flowers. Other ornamental species of include Acacia dealbata, Acacia retinodes, Acacia pycnantha, and Acacia baileyana. Willow acacia, an Australian species devoid of thorns, is also used for ornamentation. These species are usually used by landscape architects for enamoring gardens and houses. Acacia also finds immense application in the field of medicine. Acacia nilotica is used to treat problems associated with premature ejaculation. In ancient ages, the roots were boiled and used to treat rabies. The tannin extracted by evaporating the liquid obtained from the wood is used as an astringent. The feathery shoots are used in fries, soups, and gravies. Honey made by bees using the flower as forage has a mild flowery taste. The seeds are either eaten raw, roasted, or salted. Sauce and fritters are also made from the flowers. This savory is more popular in Mexico.

Acacia trees require direct sunlight in order to grow and survive, therefore ensure that you plant your tree away from the shade of buildings or other trees.

Gardeners' Notes:

Here in southern CAlifornia this is thankfully not an invasive species. it is pretty slow growing in our dry summers, but drought tolerant. I have never seen one taller than 20' and that was exceptional. THey tend to be neat, tidy trees and, if pruned regularly, make excellent landscaping trees. The color is unique.. and NO thorns (great, for an acacia!). As for hardiness, it certainly is more cold hardy than zone 10b, as these grow all over southern California in many zone 10as and I had one in Thousand Oaks, a decidedly zone 9b without any frost damage than I can recall (got down to 26 over night frequently)

On the negative side, this is a sticky tree. anything you plant below it will get covered with a fine layer of sticky goo (pollen and saps) that will then att. read more ract ants and worse. I have one planted in a planter box in my yard and below it are dozens of goo-covered succulents that I am constantly trying to clean off and remove the parasites attracted by the goo. Good tree for landscaping, but a bad tree to put stuff under.

This plant is rather unfashionable in Australia as it is quite invasive outside its own region. It is a lovely acacia. My father-in -law had one in Southern Tasmania that was snowed on fairly regularly and showed no harm. A bigger threat seems to be a warm wet Summer where growth is so fast the tree breaks under the additional weight. He pruned severely in Summer, and lost the tree the year he forgot.

An evergreen, fast growing cultivar, small tree or large shrub.

Has very showy, purple overlayed with grey/silver, 2 pinnate leaves. Bears bright gold, spherical flowerheads in late winter to spring.

It's not particularly hardy and there is a lot of conflicting information as to just how low a temperature it will stand. Personally I'm hedging my bets and bringing it in over winter.

Grow in a well-drained sheltered site, protect from frost and cold winds.
