Drought Proofing Our Gardens 2

I have been feeling really angry about statements made by our politicians about the water restrictions. On one hand we have someone saying that water use has actually increased since the Level 2 water restrictions were put in place. Then someone else says that the situation is so bad that we may have to go to level 5 with no outside watering. After all people have got to have water. Then someone else says that water use is actually down 20%. Which is it? The silence since these pronouncements were made last week has been deafening.

How can people live without water? How can people live without green plants around them? Who is it who thinks that people will actually be living if all gardens are left to die around them? How can anyone isolate people from plants? How come, when irrigation allocations are reduced, there is still adequate production? Why are these huge allocations made in the first place to individuals or companies to the detriment of an ecosystem which benefits all citizens? Why are those who use their water in a responsible way treated in the same way as wasteful individuals and businesses? Why is there so little education about the actual amount of water required by plants, the best cost effective way to water, to set up sprinklers or drippers effectively, to use timer taps, to improve soil moisture retention, etc?

In spite of the fact that I feel extremely annoyed, I look at a plant like an Eremophila (emu bush) knowing that the gorgeous flowers celebrate a plant that is drought hardy. It is useful as a feature plant or hedge or screen. Also, so long as it has good drainage and is trimmed occasionally as emus or kangaroos would do it, it will provide pleasure in the garden for many years. There are so many useful Australian native plants like this.

I will get over the feeling of helplessness I have one of these days. I just have to do my bit where I am and hope that lots of individuals like me are doing the best that they can also.

The Eremophila shown is a beauty in that it comes in shades of cream, pink, lilac and ruby and probably some others I don’t know also. It is a mallee plant. That is it grows in mallee woodland areas. I like the calyx which is left after the flower has finished, giving the plant the appearance of another flowering.

Drought tolerance in plants is a relative thing. For example, a plant originating from an area of high rainfall may grow quite well here. It may never reach the ultimate proportions mentioned in books or on plant labels but will be a good looking plant–foliage or flowers, whatever is the special feature of the plant– on say one watering a week. The same plant may never need watering apart from natural rainfall in another area. Our low rainfall makes it difficult to maintain growth on many plants without some supplementary water. This, of course, assumes that the plants are already established, which can take up to two years.

How do we drought proof our gardens? How do we manage the plants we have so that they can remain reasonable looking in a time where water restrictions make it difficult?

There are some actions that I want to take over these next few weeks with my own plants.

Beaufortia squarrosa is a shrub with brilliant red flowers. It flowers for months from spring through to autumn. (It is similar to Melaleucas). This is another of the shrubs we tried to rescue from the bulldozer. It was cut back hard and put into the new mound that was made to provide the extra drainage required by many Australian native plants.

Beaufortias need particularly good drainage. They are drought tolerant as we proved with this plant. It rarely received water other than the natural rainfall during winter and early spring, totalling 340mm (13 inches). Beaufortias are restricted to Western Australia and most are in the south west. Years ago when we were touring in the south west I remember seeing these brilliant ‘flames’ along the side of the road. I am not sure which species it was but sights similar to this photo were what we were seeing.

We must have some 35mm slides of this species. I must get the scanner going.

Even more plants were cleaned up by the bulldozer and involved a rush to collect cutting material as these were not in the plans given to us. A special planting of young Eremophilas was moved on Monday and just as well it was done. It was a matter of not trusting what we had been told and our doubt was vindicated.

The plant in the photo (two plants in fact) were pushed out because of the development taking place. This patch was suppose to be saved.

Lasiopetalum baueri is a pretty plant when in flower and attractive anyway because of the overall rusty appearance caused by the dense hairs on the stems. It is drought tolerant and hardy to most frosts. It puts on its flower display in spring and responds well to light pruning after flowering. It would make a good hedge or low screen plant. The one I have in the garden is a rounded shrub because of the tip pruning that I do to take cuttings

Rescuing Eremophilas

We were once more at the retirement village this morning attempting to rescue some Australian Native plants from the bulldozer. New retirement homes are being built and three of them will cut well into the park next to the existing village.

Plants that have been there for many years went today. We attempted to move a dozen of them by chopping the tops back hard and getting them into the ground again quickly. I have been using the chopped material to take cuttings. The trouble is that some of these have the reputation for being difficult to strike. That is why they were planted there in the first place. It was an attempt to conserve the plants at a time when it was not popular and arboretums were only just beginning to be seen as a place to conserve plants.

The photo is of an Eremophila (emu bush) which has probably gone now. No one seemed to know for sure whether it would be in the way or not. I am not sure of the name of this species. Some homework for me.
