Goldfish eggs

In March 2021 I bought ten small shubunkin goldfish.  

The fish arrived in the post, and were lovely small colourful fish.  I put them in a barrel that I had filled with rain water, added a floating pot of herbs, some duckweed and azolla, and put in a small submersible solar pond pump that pumps the water through a milk bottle filled with gravel that acts as a filter.

The fish ate all the duckweed pretty fast, and mostly leave the azolla alone.  I assume this is because the duckweed is small enough to fit in their mouths and the azolla is a bit larger.  

I try to add more duckweed every few days so they always have some food available and don't have to wait hungrily until I feed them.  Having a little azolla floating around isn't a bad thing so I sometimes scoop a little azolla out but always ensure that I leave some behind.

Water is pumped through here as a biological filter

My plants grew incredibly well over winter, but as the weather warmed they ran into some issues.  One of the issues is that the milk bottle full of gravel was knocked off and all the plants were destroyed by a possum or something.  As you can see above, I have started seeds again.

The water has started to turn very green.  I have planted more plants/seeds, but it will take time before they are large enough to clear the water again.  I do some partial water changes, but there are ten fish in the barrel so the water is always reasonably green.

Presumably this is not too big an issue and my fish are healthy as they are spawning!


Look very close and you may see a goldfish egg

The goldfish appeared a bit randy as the spring weather warmed.  Goldfish are known for eating all of their eggs, so I added a spawning mop to the barrel.  The fish have laid some eggs on the spawning mop.

I was busy that day, and in the afternoon there appeared only to be a small number of eggs left.  Presumably the other eggs were all eaten.  I moved this spawning mop with the few remaining eggs into a flexi-tub of water that is in my greenhouse.  The picture above is two days after the spawning mop was moved, the remaining eggs all appeared clear, which is a great sign that they are fertile and developing.

I also made another spawning mop with far more strands and added that to the barrel.  Perhaps the larger number of strands will protect more eggs, and provide a greater chance of some hatching and surviving.  I have checked it once and it has a small number of eggs, I plan to leave it a few more days and hopefully it will collect far more eggs.

Flexitub of water and spawning mop of eggs

The flexitub had been sitting in the greenhouse for many weeks filled with water as I was hoping to get a water lily but haven't yet found one for sale anywhere.  This tub now has some algae and tiny critters living in the water.  I figured this was a good place to move the fish eggs.

I also have a container of water which has a few small pots of sphagnum moss, this water is teeming with tiny life.  I also tipped that water into the flexitub to increase the amount of tiny things swimming around in there.  

If any of my fish hatch they should have plenty of tiny swimming things that are hopefully the correct size for them to eat.

I will add the second spawning mop to the flexi-tub at some stage, than I have to wait to see if any baby fish survive.  They will be tiny and relatively inactive after they hatch, so it will take a few weeks of growth before I will be able to see any baby fish that are in there.  Fingers crossed I get a decent number of baby fish from this hatch.

Hacor Coriander, Hot & Spicy Coriander

I love coriander (Coriandrum sativum), it is a great edible herb.

People either love coriander or they hate coriander, there does not appear to be much middle ground.  Some people have a broken gene which makes this smell and taste dreadful to them, but for the rest of us coriander leaf is excellent.

I have been growing coriander and deliberately crossing as many varieties as I can for a while.  The resultant seeds are genetically very diverse, and allow to quickly select for plants that perform well in different climates. 

Last year I got some seeds of 'Hacor coriander'.  Hacor coriander is also called 'slow bolting' and 'hot and spicy Coriander'.  Hacor coriander is said to have a stronger taste than regular coriander.  Like all coriander, this plant is grown for its edible leaves (which confusingly Americans call 'cilantro') and seeds/fruits (which Americans call 'coriander').

I liked the sound of hot and spicy coriander, so I grew some of this Hacor coriander to test it out.  I grew it partly to see what it was like, and partly to include in my mass crossed superior coriander.  I grew some that I bagged the flowers and saved seeds to keep them pure.


Coriander leaves

I thought hacor coriander was good, but nothing terribly special.  I didn't find it to have a stronger taste than my superior coriander, and I would not have thought to call i hot and spicy coriander. 

I might grow hacor coriander again, but I probably won't.  It was good, and productive, but nothing special.  I have crossed it with my superior coriander to keep the genetics diverse, so will likely grow that instead of hacor.

I sell seeds of Hacor coriander from bagged plants, as well as mixed seeds from my superior coriander through my for sale page.

Potato seedlings from true potato seed Australia

I was transplanting my seed grown potatoes the other day.  I have a few different breeding lines, some diploid, some tetraploid, some wild ancestors of modern potatoes, all grown from true potato seed.  

Growing from true botanical potato seed yields interesting results, and allows me to breed and create new varieties.  As the parent stock is usually quite heterozygous, each seedling is genetically unique.

Most of my potato seedlings looked much the same, some had a few stolons, others did not.  At this tiny size neither is unexpected.  One of my seedlings is producing tiny little tubers.

I can hardly wait to see what these turn into.

I didn't break this off, there is soil covering the stolon


This little seedling really wants to live!  It had 3 tiny little tubers (not all of them are in my photos) and a few other stolons.  It has since been planted in its own pot so I can evaluate it at the end of the season.

I mostly try to grow diploid potatoes as I find they taste better.  Unfortunately they tend to yield lower than tetraploids.  

These seedlings are from tetraploid potatoes, their parentage is far superior to anything you can get from the shops so I decided to try a few seedlings and see what I could produce.  It is far too early to tell, but hopefully something great comes out of this line.

I sell a small number of seed potatoes each year through my for sale page.  These are from lines that I have developed myself and grown from true potato seeds.  I can only do this in their correct season, some lines harvest several times per year, other lines only harvest once per year.  If you are interested keep an eye on my for sale page.

Pink dandelion - Taraxacum pseudoroseum

There are a few different species of dandelion, the one that is common in lawns is Taraxacum officionale.  It grows pretty yellow flowers, and is edible and useful in many ways.  For some reason people often dislike this lovely and useful plant.

One of the other species of dandelion is the pink dandelion, Taraxacum pseudoroseum, it is still edible and useful, but it grows delightful pink flowers instead of the usual bright yellow ones.  

A pink dandelion, how incredible!

Strangely enough, there are very few web pages that talk about pink dandelions.  Most of those are copied from one another, so there is little information on how to grow them or what to expect from pink dandelion plants.  I am growing pink dandelions, so I figured I would write a little about them.

Pink dandelion flowering 

Pink dandelions, just like regular dandelions, are perennial vegetables.  Dandelions have a great many uses in a permaculture garden, basically every animal eats them and they are far more nutritious than most vegetables.  The leaves of pink dandelion taste much like regular dandelions, and while I am yet to taste the roots I am told they taste pretty similar to regular yellow dandelions too.

Pink dandelion flowers start out yellow and the outside goes white then turns pink over a few days.  They are very rarely entirely pink, most of the time the center remains yellow.  The outside gets rather dark pink on its last day, which looks great with the yellow center.

Pink dandelion seeds ready for planting

The plant itself looks much like a regular dandelion, to be honest I am not sure that I could tell them apart when not in bloom.  Much like regular dandelions they do prefer a lot of water and do not cope if it is too dry.  Full sun to part shade seems to do these plants well.  It takes very little effort to grow pink dandelion plants.

I am happy to say that frosts do not bother pink dandelions.  Mine were also hit with hail more times than I care to mention.  Not surprisingly, none of this was a big deal for these plants because they are very hardy.

Sadly pink dandelions are not as hardy or as vigorous as regular dandelions, so the chances of this finding its way into your lawn are pretty low.

The leaves look and taste similar to a regular dandelion

The center stays yellow

The white part will turn pink

One thing I have noticed is that pink dandelion flowers open in the mornings and close in the afternoons.  It means that they are not the greatest of cut flowers as they tend to close up each night.  They do reopen each day, so it isn't a great loss.

I think dandelions are great in general, and I think that pink dandelions are just delightful.  As soon as I am able I plan to try and save seed from these and grow some more of these plants.  


My plants are still relatively young, and have only had half a dozen or so blooms.  More flowers are on their way, and seeds are ripening.  

Once the seeds are ready, if they don't float away on the breeze, I will try to plant them and grow more of these pink dandelions.

If I ever have extra pink dandelion plants, or pink dandelion seeds, I will list them on my for sale page so others can also enjoy growing these lovely plants.

Growing white asparagus at home

You have probably seen, or at least heard of, white asparagus.  There are no varieties of white asparagus, but the good news is that you can make any variety of asparagus grow some white spears at home easily. 

Normally to make asparagus white the grower will blanch the asparagus by putting a bucket or something over the emerging spear.  As it grows it has no sunlight, meaning it stays white.  This is simple to do at home if you are growing asparagus.  The end result is a much sweeter asparagus spear.

Often people use any of the green varieties to make white asparagus.  This works well.

Purple varieties of asparagus are much sweeter than green to begin with.  Which means white asparagus made from a purple variety is very sweet, it's quite remarkable.

Making white asparagus at home

This year I decided to make white asparagus using a purple variety.  The end result is asparagus that is incredibly sweet and very tender.

One of the spears grew a little large and started to lift the bucket.  This bent the largest spear and let in a little light, resulting in white asparagus with a tinge of colour.  

Not to worry, this was still very sweet and unlike anything you can buy from the shops.



If you grow asparagus give making some white asparagus a try.   Just put a bucket over the soil where the spears will emerge, and remember to check it every few days.

I only do a few spears per plant so as not to weaken the plants too much, but I am probably being overly cautious.  I am sure commercial farms make a lot more white asparagus per plant and have no problems.
