Keeping Our Plants Alive During the Heat

I've been thinking a lot lately about how we can keep our gardens going and keep producing food during the hot weather we've been having.


Maybe the main culprit is not the heat but the dryness of the air? Certainly here, the humidity is usually close to zero during the summer heat and the air seems to suck the moisture out of everything.

The beans form nicely on the climbing bean plants, but they almost dry on the bush before they are fully developed. The plants look fine and are mulched and watered, but the air is so dry it dries out the fruit as it hangs on the plant.

So, I've been trying to think of ways to reduce the evaporation from my plants. Things like the old sheet canopy I put over the carrots to get them to germinate or possibly some sort of shade tunnel that could also be used to ward off the first few frosts? Or get the food forest thing happening in the orchard . . .

Then last night I was visiting Molly's blog and she had a post about some online resources. Adding to my heat-induced sleep deficit (yawn!), I decided to pay the site a visit. I found an article by William Albrecht which claimed that the absence of water was not what damaged plants during drought, but the fertility and depth of the soil. That is, plant hunger, rather than plant thirst!

Dr Albrecht's basic argument is that if soil is prepared and made fertile to greater depths than used in conventional agriculture that the plants will use the available water in the soil more completely and more efficiently. He cites experiments to support his theory.

Interestingly, the vegie bed that is best surviving the heat at my place is the one in which I grew the oats last winter. The oats left the soil in a very fine tilth, although not that deep. Because I thought the oats might have taken out a lot of nutrients, I gave that bed twice the amount of manure that I normally do. I also gave it a good dig over to distribute the manure. This bed is planted up fairly densely with sweet corn, tomatoes and rockmelons and is coping much better than the maize in the next bed.

The other bed still coping very well is the asparagus bed, which I heavily manure twice a year and give the odd dose of seaweed extract and fish emulsion. The asparagus are barely fluttering a fern with the heat.

Well, it could be canopy cover - both of these beds have good leafy coverage. But so do some of the other beds. It could be the plants, but the same plants in other beds are not coping nearly as well with the heat. It could be the mulch, but most of the other beds are mulched as well, if not better. And, if anything, the maize bed gets more water than the sweet corn bed and certainly more than the asparagus bed.

So, maybe William Albrecht's studies have something to show us - prepare the soil well and deep to maximise fertility and the plants will survive. It's certainly made me think about doing much more preparation in the garden this winter to try to build the humus and soil fertility.

Which brings me to another point. In naturopathy, we talk about a person's vitality. The theory is that the more vital the person (physically, mentally, emotionally, spiritually), that the more likely they are to be resistant to disease and the more resilient they are likely to be.

Surely the same must apply to our gardens. We can't stop the heat, but maybe we can build our gardens to be more resilient to it.

Forecasts about climate change are predicting temperature rises of 0.4C to 2C by 2030, with more hot days over 35C.

This means we need to build our gardens to be able to cope with more summers like this one. I'm going to be putting some serious thought into this and I would love to hear any ideas you may have about how we can help our plants survive. I'd also love to hear if you have some areas of your garden surviving the heat better than others and what the differentiating factors might be.

Using Less and Valuing More

Well, the energy and water bills are in for this quarter, so it's time to make a comparison with the same period last year. Our consumption of:

• Gas is down by 8.5%
• Electricity is down by 15.5%
• Water is down by 8.9%

I am absolutely thrilled! And the best thing is that I don't think it has impacted on our lifestyle at all. We have simply tried to be mindful of what resources we are using. It's amazing what we can all do if we try.

So what have we been doing?

• Not having mega showers, although from time to time we have to remind someone who is taking a while
• Not heating as much - we reduced the temperature by about 2 degrees and covered up a bit more; we were still comfortable and upped the heat a little if people were sick
• Consciously turning off lights and unplugging appliances not in use (except for the TV which is always plugged in because it's too hard to get to the plug and the clock radios and things like that)
• Turning off our computers when not in use
• Cooking some foods such as oats and rice by bringing them to the boil then turning them off and leaving them to cook in their own heat

Things we could do to further reduce our energy and water consumption include:

• Eat more raw food ;} and/or obtain a solar cooker
• Have shorter showers (we try to keep them short, but we're not turning the water on just to rinse or anything like that yet)
• Install a grey water recycling system - we do put the water from the laundry out onto the garden (only with low sodium detergents, of course!) but we are not harvesting the water from the shower yet
• Mulch more in the garden

I'm sure there's a lot more we could do; I don't think we are really doing the hard yards yet.

As for other areas of resource consumption, such as transport - we are using the bus more, but because my partner's children's other home is 90km away, trips back and forth do add up to a bit of petrol. Even so, we have reduced our petrol consumption to one tank or less per week. And growing some of our own food and trying to eat as locally as possible, means our food miles have come down as well.

The other side effect we've noticed over the past year is that we are generating a lot less rubbish. We no longer put our bin out every week and even when it goes out it is generally only half full. Most weeks we would only generate about two shopping bags worth of rubbish. Even the amount we put out for recycling has reduced, as we are endeavouring to re-use things before recycling - most of my purple asparagus seedlings are quite happily growing in tin cans and the potatoes are coming up through a cover of shredded paper.

The way I feel about all this was summed up nicely in an email from the Meditation Society of Australia the other day:

How inspiring it is to walk all day in the sunshine and sleep all night under the stars. What a wonderful experience in simple, natural living. Since you carry your food, sleeping equipment, etc., on your back, you learn quickly that unnecessary possessions are unnecessary burdens. You soon realize what the essentials of life are - such as warmth when you are cold, a dry spot on a rainy day, the simplest food when you are hungry, pure cool water when you are thirsty. You soon put material things in their proper place, realizing that they are there for use, but relinquishing them when they are not useful. You soon experience and learn to appreciated the great freedom of simplicity. - Peace Pilgrim

Liquid Gold = Water Saved

My darling man came home from his weekend away to the bucket in the loo, ready to collect all our liquid gold. In discussing the whole issue, we did some rough calculations and realised that we'd save in excess of 20,000 litres of water each year by collecting rather than flushing.

Here are the numbers (based on old loo - we estimated 6 litres per flush):
Weekend days: 12 less flushes = 72 litres saved
Week days: 8 less flushes = 48 litres saved
Weekly total = 384 litres saved
Yearly total = 19,968 litres saved

These are only our flushes and are not counting the children's contributions when they are here. That means for our family alone, we will save more than 20,000 litres of water per year and probably more like 25,000 litres. I wish we'd done these calculations a while ago. It is quite staggering.

Energy, Food and Water

Given Molly's post on Peak oil? Peak Food? .....and now peak water?, I'd thought I'd do a little comparison on our energy and water consumption with where we were at this time last year. We've been trying to reduce our consumption over the past year and we've just received our end of financial year bills, so it is a good time to compare.

Water - over the past 12 months we have used 58% of what we used the previous year. Most of this saving came from over summer, when our water consumption fell to less than half of what we used the year before. Given I've got more food growing, I'm rather surprised at the result, but very, very pleased.

Electricity - comparing this quarter to the same one last year, we are using 59% of what we used the previous year. A lot of this saving is probably due to installing a solar hot water system and replacing our old electric oven and cooktop with a gas burner, electric oven stove (which is also lovely to cook on!).

Natural Gas - we are using about the same amount of gas as we did in the comparable quarter a year ago. However, since we are now using gas for cooking, this means our heating usage has definitely gone down.

Petrol - I don't have any accurate figures on this, but judging from our budget spreadsheet, we were filling up two to three times each fortnight and now we are filling up mostly only once and sometimes twice. We have been making a concerted effort to use the bus, so obviously our strategy is working.

Food - this is pretty hard to judge, as the children are getting older and are therefore eating more. However, I have more weeks where I don't need to buy any supplemental veges and so we must be heading in the right direction. Also, there are definitely less processed foods entering the house - we are pretty much cooking from scratch these days and snacks tend to be raw nuts and dried fruits or homemade treats, rather than stuff that comes in packets. Which reminds me - we often shop at the co-op where you supply your own containers, so we've reduced our packaging that way, too.

I know we still have a long way to go in terms of saving energy and water and growing our own food, but I'm feeling pretty pleased with what we have achieved this year. It will be interesting to see what our consumption is this time next year.

So here's the challenge - get out your energy and water bills and, if they record the information for you, see if your consumption has decreased. I think we will be trying to set ourselves some goals each quarter.
