Biochar pit trial for soil amendment

August 15, 2017December 10, 2017 Stephen Carlin

A biochar pit is a way to turn waste wood into useful soil conditioner. This Winter with the return to burning season I have been making some more biochar, this time burning the wood in pits. The aim is to make optimal use of our waste timber, from camphor laurel we have cut to clean up the block. Biochar is said to be a soil conditioner that lasts for centuries, better than just burning wood to ash or leaving it to rot. I made two biochar pit fires and have been very…

Aquaponics update; the first month

October 26, 2015December 14, 2015 Stephen Carlin

Our aquaponics system has been running-in and settling-down for a month now. As expected, it has needed some adjustment, but it is working well for a first time try. Now that the system has proved itself it’s time to expand and get some of those rain-sensitive Summer crops going. Tweaking the system has involved more structures, like a shade house for the pond, a sand filter, and setting up for expansion, but the main issue has been controlling the pH of the reservoir.

Heritage breed chickens for eggs

September 16, 2015December 18, 2015 Stephen Carlin

In your home flock you can choose from a wide variety of chicken breeds. The easiest to buy are the standard layer types, but if as you probably aren’t keeping them just for maximum egg production, you might find heritage breed chickens are more attractive and interesting option.

Growing watercress; green goodness

September 14, 2015December 29, 2015 Stephen Carlin

Whether you treat it like a herb or a vegetable, growing watercress is rewarding for the home gardener. In the cities you’re likely to find a reliable if costly supply, but I haven’t seen it for sale out here, and it’s very handy to have to pick at anytime for a garnish, or to liven up a sandwich, or on the larger scale to use as the main vegetable in a soup or frittata. A problem with bought watercress is that it tends to be all stem with yellow leaves low down,…

No-dig beds; are they any good?

September 10, 2015December 27, 2015 Stephen Carlin

I was keen to try no-dig beds, as they seem an ideal solution for opening up new garden areas without the considerable effort of hoeing and digging over new soil. My first efforts have not been entirely successful, although I’m still working at finding a method that works for me. Here are a few tips if you’re thinking of giving this method a try.

Growing strawberries over black plastic

September 9, 2015October 12, 2017 Stephen Carlin

This really works! As a kid we went to strawberry farms which had huge rows of black plastic with strawberries planted along them, and it always seemed a bit mean to the plants to have them almost smothered, but it really works for growing strawberries in the home garden too.

Wheat, linseed, and other chicken forage.

September 7, 2015December 18, 2015 Stephen Carlin

I’ve just opened the fence to let the chickens in to one of the chicken forage yards. There are three fenced yards next to the chicken run, one has the beginnings of a citrus orchard and grass for grazing, but the other two I have been using to experiment with chicken forage crops. My first Winter crops have been rewarding; particularly the linseed (flaxseed) and wheat. Fenugreek hasn’t done well with any of my sowings over a full year now, and the mustard I sowed there was also a fizzer this season,…

Candystripe beetroot (Chioggia)

August 24, 2015December 29, 2015 Stephen Carlin

Candystripe beetroot is a bit of fun for the vegetable patch. I’ve never seen it in the shops, and it would be difficult to sell as it looks like a plain red beet until peeled and cut, so it’s one of those vegetables that reward the home gardener with something unusual.

Growing swede (turnips)

August 11, 2015December 28, 2015 Stephen Carlin

Swedes are one of those vegetables that you either love or hate, and with their strong flavour they are probably hated by most kids, but ever since my tastes matured I have been on the side of relishing swedes. It’s the combination of sweetness and depth of mellow flavour that gets me, and says Winter in a mouthful. They are the sort of vegetable that needs to be seasonal, and growing swede in the subtropics is a very seasonal matter, you have to get your timing just right. Growing swede in the…

Burning-off season

August 6, 2015December 29, 2015 Stephen Carlin

There’s something primally satisfying about watching a fire burning-off, and Winter days give us the chance for burning-off some of the vegetation we have cleared in the previous months. There are two woody weeds in particular that we have a lot of; lantana and camphor laurel, and when we have a couple of spare hours we typically get out and clear some, which involves pulling out the lantana and cutting down the camphor laurel. The piles then sit until a winter day when it has been dry enough for a few…
