Digging yacon and Chinese artichokes

We are having some great, sunny days lately so I have been getting out to do a heap of weeding and tidying up for winter. The last of the tuberous crops to go up to Qld with me have been dug so I am ready to go, well, as soon as I clean up my van and put the seed in. Must get on to that today.

This will be my last post for a couple of weeks as I will be on the road and I probably won't be on the internet much.

 Yesterday I dug up the Chinese artichokes. I only had a few plants in after losing most of them last year due to bad management. I had them growing in a bed where I hadn't got rid of the crab grass properly. By the time the artichokes started growing the crab grass was well up and growing strongly so I couldn't get rid of it. The artichokes really don't compete well with running grasses.

Even with the few plants I had and not watering them well last summer they did produce good sized tubers. This is not a good producing crop but it is fun.
You can put the tubers in salads and stir fries for a bit of crunch, and they look amazing.








I also got into digging up the yacon. The eating tubers were great this year, and quite big, though I was a bit disappointed with the small amount of growing sets that were produced. At least I had enough to replant and to fill the order I have for them.

I will let the tubers sweeten and take them to the markets next month.





The tubers were quite crowded and I think this was because the soil amendments like lime and fertiliser have not yet sunk down low into the soil so the roots have stayed around the top of the soil rather then going down.

This will remedy itself over time as rain washes the good stuff deeper into the soil but I will have to keep an eye on it. The roots really don't like the severe natural acidity of my soil. I have also noticed this in some of my other vegetables.

As the soil gets improved deeper I will get better results every year.

Digging the Arracacha

With only a week to go till I leave on my trip up north I have started digging some of my tuberous vegetables to take. I have beds of yacon, arracacha, mauka and arrowroot to get through, clean and pack for the trip. Due to the wet at the end of last year most of the plants rotted and died so I don't have near as many as I would have liked.

 A couple of posts ago I told you about a couple of aracacha plants that I dug up to divide for replanting. They had heaps of top growth and no roots.

Well the one I dug up today only had a few small roots but at least it was enough for a meal. I had forgotten how tasty they are, like thick, sticky potato with a flavour I can't really describe and also a bit sweet. I will leave a couple of plants in the ground for another year to see what the roots do.

The roots must be cooked (I boil mine) as they are too hard to eat when raw.

The plants grew bigger this year than they ever have done before. It is probably the soil but I will have to work on the optimal conditions for not only top growth, but also root formation.

The leaves are a bit too stringy to eat though they are not poisonous.

This is a pic from last year but I decided to show it again because I forgot to go out and take some photos today.

This is how the main part of the plant grows, the roots have been pulled off at this stage.
The main stem produces smaller stems which you can cut or break off and replant.
Before planting you need to cut the bottoms of the cuttings a few times to encourage more roots to form.

Although you can dig the plant every winter if your season is long enough, you should try to leave the plants in the ground for two years for bigger roots. The plants will die down a bit to a lot over winter depending how cold it gets but will bounce back in spring.

Selecting white beetroot for seed, and frosty mornings

The frosts were late this year but they are making up for it now. We have had some fairly severe frosts the last few mornings which has finished the yacon and capsicums.


 This is what the yacon looks like now. I will be digging the tubers next week ready for sale. I really like yacon but I grow too much to eat all the tubers. I am really disappointed that I can't get people to buy them, or even take them for free.
Oh well, just like the melons, pumpkins and capsicums I will be throwing out a lot of good food.
 I have just mowed another acre, well, 3/4 of an acre once I take out the shed and yard. I am happy to expand some more and corn will go in here next spring. I wish I could expand faster but until I can find a working business partner I will just have to do what I can.
I have had a couple of bites but no-one who is interested enough to actually come and chat and see the business. It is hard to find anyone who wants to move to a small town like Casterton, even though the business has so much potential.

 Today I got to pulling the white beetroot to select the best roots to replant for seed. I was happy to see that I had to do very little roguing, just about all the roots were a good shape and size.

I sometimes see white beetroot and sugar beet called the same thing in seed catalogues but they are different. White beets are rounder and less sweet that sugar beet, and less ugly.


White beets are said to have none of the chemical that makes red beets taste like dirt to some people. I love beetroot so I don't know for sure but I should test that out one day.














Here is a pic in the middle of planting the selected roots into a new 20m bed. They will quickly recover and be healthy plants by spring when they will bolt to seed.

Today was very cold and frosty in the morning but lovely and sunny this afternoon so I took advantage of the sun to get out and get a heap of work done.

Disappointing arracacha, and digging the oca

With the weather unusually wet - we have had a wetter autumn than I have experienced for many years - I decided to dig the tuberous vegetables early so I don't risk them rotting in the ground. There have been some disappointments and hope.

The arracacha plants have grown huge and I was really looking forward to eating them this year. Unfortunately when I dug them I found that they had not made any roots. It seems weird to me as I would have thought they needed large roots to support the nutritional needs of all that foliage.

This is the first time I have grown them in the seed block so I guess that it is a nutritional/soil problem that I will have to work out.

At least I will have plenty of divisions to plant out. This is good as I nearly lost all my plants last year in the flooding.




Yesterday it was foggy most of the day and I didn't feel like getting wet while weeding so I decided to dig my oca. They had not died down fully yet so the tubers were not as large as they should be but I was starting to see some slug and mouse damage and I didn't want to take a risk seeing as how I lost nearly all my varieties last year and had a very poor seed germination this season.
I mostly only had the few tubers I saved.

Out of the 33 varieties I planted 9 died of stem rot and I kept 11 of the best producers. I also had 4 that were heat tolerant but only kept the two of those that produced ok.

The summer was pretty mild this year which is probably why more did not get stem rot. Next summer will be the real test.



The four top pictures on the left are of some that I kept. These plants not only produced decent sized tubers (which would have been bigger if I had left them another couple of weeks) but also produced around a kilo of tubers.

I will plant a heap more seed next spring in the hope that I get another nearly black tubered one that I lost last year.











This last pic shows a few tubers of plants that I tossed. These plants mostly produced badly, had small tubers, or did not grow well. I did have one variety that grew into huge bushes but didn't produce many tubers which was sad to toss out, but was a waste of space.





I have left one plant in the ground that is so far showing no sign of frost damage or dying down so I will leave it to see what it does.

Pulling my potatoes and chufa varieties

It was a lovely day today so I went out and pulled up the last of my TPS diploid potatoes and chufa varieties. We have a had a few frosts now so things are dying down and ready to harvest. The oca won't be long.

The great thing about growing potatoes from true seed is that when you have seed from a range of coloured varieties you never know what you are going to get and just about every plant has different tubers.

I was disappointed to find that I only ended up with one that had red coloured flesh and three that had coloured rings or splashes through the flesh, but what I did dig had a range of white, cream and yellow flesh. They also had a range of tuber sizes and shapes though those in this pic are all small because the plants are the latest and smallest.
 I grabbed some of the small tubers and boiled them to eat while I worked at the computer. Although I like the yellow fleshed waxy ones my taste buds are not sensitive enough to find much of a difference in taste. They were good anyway.


I told you that the rabbits kept eating my peanut plants so I thought I would not get any nuts off them, well, I pulled up a couple of plants and found that I will get enough nuts to plant again next year.

Just in - my young niece is visiting and watching me type this. She asked me to tell you this joke:

What do you call a peanut?
A nut

Well, she will understand a bit more about jokes when she gets older, lol.

I pulled up my 4 varieties of chufa today. I put a few on plates to show you what they look like.

Starting from the left:
*Spanish (productive)
*Black Tiger (the biggest)
*My usual un-named one (the most round)
*Jumbo (didn't live up to its name but it could have been the conditions so I will see next year)

As far as taste is concerned, Spanish was the sweetest, Jumbo the best tasting with a good almond flavour, and the other two were fine but milder.

Selecting Pusa Asita carrot

I am so looking forward to the winter break. The mornings are getting too cold now to be out when the sun rises so I an enjoying sitting at home a bit longer and just working mostly in the afternoon.


I started to harvest the chufa and found that mice have been living among the roots and eating them. I have only been able to gather half of what I expected.
 I was so worried about rabbits that I didn't even consider the mouse problem.

At least the longer than usual season means that the tubers are also bigger. I have enough to sell and some left over to eat, yam.

Today I dug up one small bed of 'Pusa Asita' carrot to choose the best roots to replant for seed.

If you have been following my journey with this carrot you will know that at first I had so much trouble germinating it that I crossed it with 'Cosmic Purple' just to get the germination percentage up.

The germination is a lot better now but I have spent the last couple of seasons selecting back to dark purple/black to the core. Cosmic purple has a yellow core.

The colour seems to be getting a lot better. I dug up 75 carrots and only had to bin three for yellow or white cores and five for having a thin yellow ring around the core.
Hopefully I won't have any light cores at all next season.

 I am also selecting for purple foliage and pink flowers.

Too bad the dark purple flesh stains everything from your hands to the benchtop. At least the dark purple pigment is full of nutritional flavonoids. At least the flavour is good and it doesn't loose its colour too easily when cooking.

 The worst thing about this variety is that it is so damn sensitive to soil conditions. It is usually a fine shape till it matures and then if the soil conditions are not exactly right the roots get so ugly it is hard to even look at them.
Some of these roots got eaten tonight, they are still tender even like this.

I understand it is an environmental problem but I don't want to have to worry about fixing the soil especially for them so I am selecting away from this trait. I want them to do well in any soil.
Only the best coloured single roots go back in the ground. Out of this lot I have selected 36 to replant.

I have another bed that is younger so I won't be digging them till well into winter.

Slowing down for winter

Sorry it has been a while, there is not much happening besides weeding and harvesting the last of the capsicums. Soon I will be digging my chufa but they are still a week or two off.
We had out first light frost this morning which is quite late but I am glad as my oca is only just tuberising now. It is also late which suggests to me that although day length is the main driver for oca tuberising, there is probably something else at play also.


 With a couple of nice days I decided to make new benches for my parents greenhouse. The old, metal benches were so rusted out that they were falling apart.

It is very easy to make benches, all you need is a few treated pine posts, some other timber to hold up the tops and an electric driver and screws. Getting enough boards to make the tops was the hardest thing and I think I might have to buy some to finish off one of the benches.

They don't take long to do so I thought I had better do them now before winter makes it too cold and wet and I will rather stay indoors, lol.

These benches are 7 metres long and one metre wide and after I finish the last of the three I think I will have racked up a bit of good will. My mother is already pleased and has already loaded one of them up with young cyclamens in pots.
I will make another bench underneath to hold empty pots when I get the materials later.


I am really looking forward to going on my annual trip up north to chat with my seed buyers next month. That trip is basically the cut off between work and my three months off.
