| Choose Garden Tools
When you buy equipment or materials for your garden, you usually get what you pay for. The things which do the job well and last are usually the more expensive choices.

| Gardening in Dry Tropics
Soils can be dry for any one of several reasons:
a/ The soil is sandy and doesn't retain water.
b/ Rainfall is minimal.
c/ Areas under the canopy of trees where rainwater doesn't penetrate to the ground underneath. This type of position often has two other problems ‑ these being shade and a dense mat of tree roots that penetrates the soil and competes with any plants you try to establish there.
d/ Water is not absorbed easily. This could be for a number of reasons such as poor soil structure (eg: hard packed clays), the presence of quantities of rock, or water repellent soils such as some fine sands.
e/ The soil is under the eaves of buildings....(Excerpt from page) Click to read more

| How to Prune Apple Trees
In the past apples were trained into central leader shapes, having a central leader and evenly spaced out branches and stone fruit into vase shapes, however these days many people find the open vase shape easier to maintain and easier to harvest fruit.
In the home orchard the tree will produce plenty of fruit whichever type you use.
As Malus are often grafted or budded, care should be taken to remove suckers, especially those which emerge below the union. When fruiting, pruning is necessary to keep the tree open and prevent crowding. Branches may start drooping from the weight of the fruit. Cut the drooping part back to growth which is almost vertical.
Most apples fruit from spurs which are three to four year old short stems. A few types bear fruit at the tips o...(Excerpt from page) Click to read more
| Lawns in Warmer Places
Nearly everyone loves a beautiful lawn, even non-gardeners. It's one of the first things most of us think about creating in a new garden, perhaps because it's one of the easiest and often cheapest way to quickly "finish off" a new home. Once the grass is down, it's much easier to keep mud and dust out of the house, it makes the property look much neater, and it's not so much of a hassle to let the children out to play, or to invite guests over for a visit....(Excerpt from page) Click to read more

| Prune for Better Looking Plants
Any amount of pruning causes some degree of stress to a plant. Ideally, plants of suitable growth and habit should be selected for the site in which they are to be grown but this is not always possible. Also, some people prefer their plants to have a more manicured appearance, perhaps to fit in with a formal garden style.
It is important to remember that different plants have different levels of tolerance to hard pruning. With some plants, you can remove 50% of the foliage and this will result in improved vigour and health. With other types of plants, removing 50% of the foliage will cause death. Occasionally you may encounter a plant which has low tolerance to hard pruning that will survive a hard prune, but this is not typical. It is better to find out what are re...(Excerpt from page) Click to read more
