Thyme progress

For some reason it is difficult to find many named varieties of thyme in Australia.  For some reason it is almost impossible to find any comparisons of thyme varieties.  Plant nurseries write such lovely things about their plants, but an honest side by side comparison is practically unheard of.

Last year I wrote a post comparing some thyme varieties to highlight the differences between them.  To expand on that, below are comparative pictures of the growth after about 6 months.  The pictures were taken at the beginning of spring after the plants had survived winter.

I wish I had planted them further apart, but I needed the space so they are cramped together.  The small pots contain cuttings of each variety.  You can see how each of the varieties of thyme grew compared to the others.  They are probably each double that size now and have started to flower.

Four varieties of thyme growing side by side.  It is pretty obvious that Jekka's thyme is larger and stronger than the other varieties.  It goes outside of the picture to the left somewhat.

Grow more dandelions

I like dandelions (Taraxacum officinale).  They are a perennial edible plant that are easy to grow.  I allow them to flower and set seed in my yard and encourage them as best I can.

Dandelions have many uses.  People eat the nutritious leaves and roots, they are high in vitamins minerals and inulin, nice coffee substitute can be made from the roots, wine can apparently be made from the flowers, animals relish all parts, bees (both native bees and honey bees) and other pollinators just adore them, they have medical uses, and they can be useful in composts.  Dandelions flower for much of the year where I live now, which is great for bees and other pollinators.

If you look closely you may notice that every photo on this page of dandelion flowers has a honey bee somewhere in the picture.  Bees really seem to love dandelions.

Dandelions have many uses, they grow reasonably fast, they are reasonably productive, they have no real problems with pests or diseases, and they can just grow in my lawn so do not use space that is needed for other vegetables.

I don’t see what is not to like and I like to encourage people to grow dandelions in the lawn.
Dandelion - you should grow more of them!
I have never understood why anyone would want to get rid of dandelions from the lawn or why dandelion poison exists.  The only problem I can think of is that they don’t survive if it is hot or dry.  That is no real reason to poison them though.

I have read permaculture sites and gardening books who claim that 'dandelions are a gift from nature that freely grow everywhere and thrive in damp as well as dry places'.  Even though I wish this were true, this is not the case.

Overwintering diploid potatoes

Last year I grew some diploid potatoes from true potato seed.  I really enjoyed it.  Every single plant produced different potatoes.  Each of them tasted far superior to anything you can get from the markets.  They were quite remarkable.

Unfortunately these diploid potatoes lack any real dormancy and start to grow not long after producing tubers, so it was unlikely that they would survive winter without help.

Being seed grown meant that each plant was unique, and I would love to keep the best new varieties alive.  Unfortunately I lack the time and space required to grow them via tissue culture, which means I had to think of a way to keep them alive through winter.

I attempted three methods of overwintering potatoes, putting them in the crisper of the fridge, leaving them in the garden, and putting them in a pot in a protected position.  Read more and I will explain what worked for me and what didn't.

mulberry tree time from planting cuttings to fruiting

Have you ever wondered how long it takes for a white mulberry to go from a small cutting until it is large enough to fruit?  I have grown cuttings a few times so thought I would share my experiences and hope that it helps someone.

I have looked on the internet and found a nursery overseas that claims they sell 2 year old plants that should fruit in 2 - 3 years.  That seems overly long to me.  Judging how quickly I get things to fruit from cuttings or seed grown and how much longer they claim it takes for 2 year old plants to fruit I would have doubts over the quality of their plants and/or the accuracy of their claims.

Large mulberry cuttings can fruit that same year, but what about small cuttings?  Obviously it varies from plant to plant, some will fruit much faster or slower than others, and the climate will change things.

Here are some photos of a cutting that I took of a cutting from a white mulberry that is meant to be white fruiting (most white mulberries are dark fruited).  The cutting was around 10cm long and far thinner than a pencil.

My little cutting went from this tiny cutting just sprouting roots September 2017:

to this small ~60cm tall tree just before going dormant:

to this little tree emerging from dormancy in October 2018:

Unless something goes wrong I should find out in a month or two if it is white fruited or dark fruited. 

Mulberry breaking dormancy - note the catkin emerging
Almost every node that is producing leaves is also producing catkins, each of which should turn into mulberries.

It appears that this will be a productive tree once I plant it in the soil.  I am hoping that it will be white fruited, but even if it is dark fruited I think it will still be well worth growing.






 


I am waiting until the fruit ripens before planting this tree in a larger pot or in the soil.  I would hate for transplant stress to cause it to abort its fruit and have to wait another year.

I am assuming that some varieties of white mulberry take longer than this to fruit.  I assume that some varieties will be more productive and others less productive than this one.  Regardless, it appears that this is a productive and reasonably fast growing variety.  Going from a cutting to a fruiting tree in a year is pretty impressive.  I don't know of many fruit trees other than mulberry that can do this.

Skirret in Australia

Skirret (Sium Sisarum) is the ultimate perennial vegetable.  As far as I am concerned skirret is the perfect vegetable for organic gardeners, permaculture gardeners, people who are into increasing self-sufficiency, people who are increasing their food security, and people with fussy children.   That’s right, even fussy kids will eat skirret.

Skirret has a long history as a vegetable, it has been blessed with the highest recommendation and cursed with the lowest popularity of any of the root crops.  It grows wild across Asia, and has been well established across Europe.  Skirret may have made its first documented appearance in a 1322 list of seeds maintained by the gardener for the Archbishop of Canterbury, Lambeth Palace, which included a penny's worth of skirret in a 1321 to 1322 inventory.  We don't know how long it was used as a vegetable prior to this, it is believed that skirret grew along damp riversides and ditches and was easily harvested for free, so didn't need to be bought and sold.  It is likely that skirret was grown and eaten long before this but simply not recorded.

People keep telling me that there is no skirret in Australia, but I grow skirret, I sell skirret, and eat skirret.  I have given skirret to some people who now also sell it.  So skirret is slowly becoming less rare in Australia.  Hopefully one day I will see skirret for sale at a farmer's market.

I adore skirret, I have grown it for a number of years now, have written a few posts on it to try and show other people how to grow it.  Skirret is the most delicious roast vegetable ever.  I have never eaten anything that even comes close to how great skirret tastes.  I like the taste normally, but frosts make it far sweeter.  I want to encourage more people to grow this remarkable vegetable.

Growing string of pearls succulent in water

I love string of pearls succulents (Senecio rowleyanus).  There is something special about their almost spherical leaves with little windows, and the crazy way they grow out of their pot and drape over the side that I love.

I started two tiny cuttings a while ago and have expanded my stock significantly since then by planting more cuttings.  They are a delightful and surprisingly simple plant to grow.

Unfortunately my two year old shares a similar fascination with these plants too.  He likes to rip off the longest strands and hide them around my yard or in boxes.  While I would prefer he didn't do this, and would prefer to have longer strands growing, whenever he pulls parts off I use them as cuttings to create more plants.

Small string of pearls plant
Normally when I take cuttings of string of pearls plant I remove the lower few leaves (its leaves are the round pearl things), then I stick that lower part in soil, and that is all.  In a few weeks the cutting has roots and the top is actively growing.  Very simple.

So far, even using cuttings that have been ripped off by the baby and hidden in the yard for a few weeks, I have had 100% strike rate.

String of Pearls cutting ready for planting
Recently I heard of another method to grow string of pearls cuttings.  Instead of putting the cutting in soil, you put it in a glass of water.  I root plenty of other cuttings in water like this but not succulents.  Being a succulent, and having such great success simply planting cuttings in soil, I had not even thought of rooting them in water.

I was intrigued if the cutting would grow or if it would simply rot.  Curiosity got the better of me so when the baby pulled off a strand I gave it a go.  I think that it is fun learning new things.

The water method of rooting string of pearl cuttings is much the same as the soil method I currently use.

I take the cutting and remove the lower few pearls as normal.  Then, instead of planting in soil, you place the lower section in water.  Common sense tells you that only the lower part goes in water, the top section with leaves remains above the water level just like most other cuttings.  To be honest, I can't think of any cutting that you would totally submerge other than fully aquatic plants.

I have an egg cup on the kitchen window sill where I grow a few cuttings.  A jar would probably work better, but the egg cup takes up so little space.  So I put the end of the cutting in the egg cup, and the top is draped out of the water towards the window.  As the egg cup is so small it has to be topped up with water each night which ensures less algae growth and more oxygen is in the water.

Strangely enough all went well.  In a couple of wees roots started to form and the cutting was ready to be planted in soil.

String of pearls cutting actually grew roots in water!
I expected it to rot, but it grew roots pretty fast
Not only did roots form, the tip started to grow longer.  This indicates that the plant is alive.  Towards the end the cutting started to put down more roots in search of soil.
Growing longer and forming more roots
At this stage the cutting was ready to be planted in soil.  If you grow string of pearls plants in water then this is the time to plant them in soil.  Once again curiosity got the best of me.  I started to wonder how long the string of pearls cutting could survive in nothing but water.

String of pearls is a succulent, and succulents are adapted to growing in dry places, growing a succulent in water feels strange.  It was worth giving this a go simply to learn more about this fascinating plant.

String of pearls roots getting longer

Surprisingly enough all has gone well so far.  The roots have gotten pretty long.  The plant is growing longer and seems reasonably healthy.

So far the only issue is lack of light as I am growing it in the kitchen where it is bright but there is little to no direct light.
Internodes are a bit long as the light levels are too low


I figure sooner or later my string or pearls cutting growing in a glass of water will start to rot.  When that happens I will cut off the rotting section and plant the rest in soil so it can root and grow normally.  Hopefully that works so I have not lost anything in trying this.  It is fascinating though.  I wonder how long it can actually survive in water like this.

-----------------------------------------------------------------------------------------------------------------------

Update from April 2019: I started the string of pearls cutting from the pictures in water back in late August 2018.  It is now April and it is still going strong.  Who would have thought!  It is not as large as ones of the same age that I grew in soil but still looks healthy.  So far its only issue is not getting enough sunlight because I have had it growing on the kitchen window.

-----------------------------------------------------------------------------------------------------------------------

Update March 2021: my string of pearls cutting in nothing but water died after two and a half years.  

It fell out of the water and I didn't put it back in for a few weeks.  The stem got bruised/broken from having something heavy placed on it, making the roots die.  I tried to put it back in water in hopes the roots would grow again, but they didn't, I think it had been out of water and crushed for too long.  Had I noticed earlier I think it would have survived,

I think this would have kept growing forever if the plant had more sunlight and it didn't fall out of the water.  

This cutting didn't rot, it never flowered but it kept growing longer and branching.  It lasted two and a half years in nothing but water!

-----------------------------------------------------------------------------------------------------------------------

If you want to grow a string of pearls plant I sell string of pearls cuttings as well as small string of pearls plants through my for sale page.  At this stage I only have the regular green variety, I plan to have the large variety and the variegated string of pearls plant for sale day too.

Red Fleshed Huonville Crab Apples

When we lived on acreage we had many apple trees.  We had three mixed orchards, each orchard had some apples.  We had some old heritage apples, we had over 50 espaliered apples consisting of four newer apple varieties.  We also had a few other things such as medlar.

Now we live in town we have far fewer fruit trees.  One I particularly like is the Huonville Crab Apple.  It is believed to be the cross between a domestic apple and a crab apple.  It grows small edible apples and is pretty enough to belong in an ornamental flower garden!  The apples are red fleshed, which is very rare in Australia, but it has other traits that I also like.

The bark of the Huonville Crabapple is a lovely dark colour.

Domestic apples the branches are often more green
During the growing season the Huonville Crab apple leaves are a beautiful purple colour.  Most types of apple leaves are varying shades of green.

Huonville Crabapple flowers are a dark pink.  They are incredibly beautiful.  Before they have opened they look like tiny roses.  Most domestic apples are a pretty light pink/white when they flower.  While I like the look of both, and am glad to be growing both, I prefer the look of the darker Huonville crab apple flowers.

The flesh of Huonville crab apple is red.  I will try to remember to take some pictures of them this year and put it up in another post.  Even the sap of the Huonville crab apple is purple.

I am quite taken by this tree.  The dark trunk, the purple leaves, and the stunning flowers look amazing together.  The dark red apples with red flesh are great, I think they would be better if the apples were just a little bit larger.
