FLOWERS

Now is the time to start watering your flowering and fruiting trees with Liquid potash. It is also available in a granular form but a friend told me about the liquid as it is much easier to use. This can be both watered and sprayed onto your trees. Do it every 2 weeks until flowering next spring. It is very high in potassium which is the goodies you need for fruit and flowers.

It Is N 0%, P 4%, K 20%.

It is available at most Bunnings or nurseries.

FERTILISING

Don’t forget to keep up the fertilizing at the moment. Even though the trees may seem to have stopped growing, they are still hard at work storing all their nutrients for spring. If you fail to keep this up at the moment, you will pay the price at spring time with less than efficient growth, and dieback of much of the small branchlets that take so long to develop. Remember that growth must come from somewhere, and that somewhere is nutrients stored in the trunk and large roots. This is especially important if you are trying to increase branch ramification on trees as well as fruit and flowers.

DECIDUOUS TREES

This is a good time for exploring your trees as they defoliate, it’s a great time to consider if the tree needs restyling. Often over the growing months, the tree will send shoots out all over the place. Whilst the tree might look good in full foliage, its not until you see it with out its leaves you realize that the tree is really messy. Now don’t be lazy and just leave it as it is thinking it will look good again when its got all its leaves in spring! Take the time to go through all the branches and cut of all the branches that have grown to long, have grown to far upwards, shot downward under the branch, and grown outside the overall shape of the tree. Now wire any branches into their correct position. Remember that refinement is an ongoing work on your trees. Being deciduous it just makes it easier to get to.

This will pay dividends over the years with great ramification, which is just as important as your summer look.

There is nothing more stunning than a elm or maple that has hundreds or even thousands of tiny little branchlets in winter. Believe me this wont happen naturally, it takes time, pruning, fertilizing and vision. By vision I mean seeing the future shape of the tree, by starting at each individual branch.

Most people are a little timid when it comes to pruning their deciduous trees. It is really important to be quite hard in cutting them back. Especially with trees such as elms, you need to be fairly savage. Remember to cut to the bud that you want the branch/branchlets to grow in.

By doing this you will create shorter internodes (the distance between the buds) which will give you better ramification. If this is not trimmed or pruned each year, you will gain a mass/mess of little twiglets that will not produce the fine even growth you are trying to achieve.

Pines also can be pruned quite hard now also. Remember to take out the larger candles at the top, and the smaller candles lower down as they are dominant in their apex. If this is not done then the tops will grow at the expense of the lower and inner branches.

By cutting back this way smaller buds will form at the base of the cut which will produce next seasons branchlets, which in turn will need to be thinned. This will help produce those elusive smaller needles and compact growth.

CLEANING CONIFERS

As your conifers begin to slow down in growth, you will notice that as the weather cools that you will get “die back” inside your tree. The reason for this is that sun is no longer penetrating this area so the tree stops producing new growth underneath. This leads to lots of small brown needles which if allowed to stay, will produce the ideal living place for lots of bugs (if it already hasn’t.) Much of insect infestation can be avoided by keeping your trees well groomed and clean.

The best way to remove these old needles is to use something like a chopstick to loosen all the old matter. After you have done this is then worth going over the tree and shortening all the smaller branchlets that have grown over 25mm in height above the branch. By doing this you will allow light to penetrate inside the tree which is imperative for health, good growth, and short compact ramification. This is how these lovely compact clouds are developed.
