Tropical Climate

What To Plant in April?

• What to plant is determined by the weather. My notes are relevant to the areas where you plant the tomatoes in the dry season. This is my test of whether it is a sub-tropical or tropical climate. Tomatoes planted for the wet season will grow long and spindly but will not fruit before the dry season. Plants which have self-seeded are naturally germinating now, the beginning of the dry season.

• April is a transition period from the wet season to the dry season and so planting is risky. There is a low forming up north so there may be some more heavy rain. This wet season has not been wet, with only a week or so of wet weather. The strong winds which signal the end of the wet season, called the ‘knock-em-downs’ in Darwin can cause a lot of damage in the garden. Seeds can be washed away and young plants bashed and drowned.

• Now is the time to plant all the cooler climate vegetables vegetables that are normally grown in summer in the cooler climates. Try everything you want to grow. The list is endless. I put in kale sometimes, knowing that the flavour is not the best without a frost, and hope for some unusually cold weather.

• Continue to practice crop rotation to reduce the likelihood of pest and disease infestations and to manage the fertiliser in the soil.

• Prepare beds for further planting by applying well-rotted manure and compost and dolomite to sweeten the soil. Fork it in and allow maturing for about 2 weeks before planting.

• Keep seed beds moist but not wet. Beans may only need one further watering prior to germination. Smaller seeds like carrot are more sensitive and will need daily watering and a light layer of mulch on top. I have also used thick hessian bags to keep the soil moist till germination. Check daily for germinating seeds and remove as soon as most of the seeds have germinated

• Planting seeds of hearting lettuces and plants which form a bulb like onions early allows for substantial vegetative growth before the cold weather initiates hearting or bulb formation.


• The weeds have not stopped growing vigorously so keep on top of them.

• Turn in any green manure before it flowers so that it can break down while the weather is still warm and the humidity high. This will increase the rate of decomposition in the soil.

• Planting can commence in these areas prior to be breakdown but added nitrogen will be needed.

• Fertilise trees and perennial plants with trace elements to build the soil up for the dry season and replace micronutrients leached by the heavy water inundation.

• Start looking at trees which will need to be pruned at the end of the wet season. Pruning now will not cause the flush of new growth which follows pruning during the wet season when almost everything is in active growth.

Weeds, Pests, and Disease

• The citrus leaf miner is active so I just pull of the affected leaves and put them in a plastic bag for binning. Most of the time I don’t even notice them and the world does not end.

Harvest and Preserve

• Harvest the last of the wet season crops now. Those left in the ground will provide growing material for next wet season but the tubers will not be very palatable.

• The sweet leaf is slowing down as the weather cools down so stop harvesting for the dry season.

• Harvest plants like yard-long beans, okra, capsicum and eggplant regularly to keep the plant in active growth.

• Bananas and longan are still being harvested.

Permaculture Principle #4: Apply Self-Regulation and Accept Feedback

• Feedback can be positive or negative and both are necessary to teach us about the system and it’s needs.

• The distance and disconnectedness between elements of the current system reduces the likelihood of feedback being noticed and interpreted correctly. The productivity of our soil is decreasing but the general population is not aware of this nor are they aware of the amount of artificial intervention required to produce our food. We are also not aware of the resource cost of what we consume or what we export.

• The capitalist system negates the validity and reliability of feedback to survive. It depends on ever increasing consumption. This does not indicate that the capitalist system is all negative as it is not. The disconnect between production and consumption and the impact of advertising serves the vested interests and not the long-term interests of society or the planet.

• The permaculturist is aware of, and open to the information provided by feedback systems. This is relevant to our income source, our food production, maintenance of soil fertility and structure and the plants we grow. If we listen to the feedback we will learn what grows in our climate without massive amelioration of soil and climatic conditions. Why grow food plants that require a greenhouse when we can choose to grow plants that suit our climate and garden conditions?

• My lack of any pest control in the garden is based on the belief that the system will provide the controls it needs to work in balance and harmony. The pest may attack a plant but the predator is on hand to control but not eradicate the pest. If the pest was eradicated then there would be nothing left for the predator to eat and it would therefore move out or die.

• Listening to the feedback may tell us that we need to be looking for other sources of income. The typewriter repairman may not have seen the rise of computers and therefore would not have realised that he needed to find another way of generating income. The repairman who did see the signs can retrain in another area or specialise in working on typewriters in museums.

• Without negative and positive feedback we do not learn and adapt to changes needed for survival.
