Dahlia Experiments 2025 - Growing Dahlia Seedlings
Hello friends,
As part of my dahlia growing experiments this year, one of my goals is to grow my own dahlia plants from seed. I have a stash of dahlia seed available, including the Bee's Choice dahlia variety from Floret in the USA (which I bought from Emerden last year), Beeline I and II dahlia seeds from the breeder Doctor Keith Hammett in New Zealand, dahlia seeds from Susie Ripley's garden in Dunedin, and also open pollinated seeds from my own garden.
At the end of August, once I was able to garden again after my second cataract surgery, I sowed my dahlia seeds into two covered seed trays, and sprinkled them with enough seed raising mix to cover them.
With them watered, and kept moist in the trays, the dahlia seeds stayed in our dining room in the warmth while they germinated. To my surprise, most of the dahlia seeds I planted germinated, at a rate of about 95%, which is way more dahlias than I expected to plant in my garden this year.
They grew nice and strong, and soon they were ready to transplant out into bigger pots with potting mix. They've been growing safe and sound in my glasshouse since then, growing bigger each week. My plan is to plant them in the garden after the last frost, but for now I have to figure out where I'm going to put 43 dahlia seedlings...
I can't wait to see what dahlia flowers appear from these seedlings over the summer. My plan is to be quite harsh with them, and I'll pull out any flowering plant that I'm not happy with, to give other dahlias room to grow. I'll give you updates as I go...
Have a wonderful day

Side Garden Project - Planning and Building Raised Garden Beds
Hello friends,
After we had taken down the old aviary/berry cage, it was time to get to work turning this space into garden beds.
The first task was to weed the area, tidy up the fence line, and move two concrete pavers. Once I pulled out all the weeds and then tidied the fence line by putting old pieces of wood up against it for protection, hubby and I maneuvered the pavers into the space next door, where I have my worm farm located.
With all that done I ordered macrocarpa sleepers from our local garden centre for creating the new garden beds. The sleepers are 1.8 m long, which was the exact size we needed for that space.
The next step was to first put up some old trellises for our raspberry bushes, so we could train them along the fence line. We then create 90 cm wide beds using the macrocarpa sleepers, with 50 cm pathways in between for easy access to the garden beds. It was a lot of hard work considering there was a lot of river pebbles in the area. We transferred those river pebbles into the pathways between the garden beds when we were finished.
Once all the beds were in place, hubby did the hard work of digging over the garden beds and adding compost. The first bed closest to the garden shed was set aside for the strawberry plants I had put into pots in the glasshouse before the aviary was removed.
The next garden bed was set aside for my natural dyeing plants including Madder, Woad, St John's Wort, Tomentil, and Lemon Sorrel, which I had squeezed in another garden bed down the side of the house. While transferring the plants I was able to harvest some of the madder roots for natural dyeing. I have enough space leftover now to put more natural dyeing plants in the other half of the garden bed this spring.
Garden beds 3 and 4 are currently empty, and they still need to have compost added, before being prepared to a fine tilth for spring.
My plan is to grow Linen and Japanese indigo plants in bed 3: I have my own homegrown flax linen seeds in storage from last year, and I bought Japanese indigo seeds from Growing Textiles last autumn with the intention to grow my own indigo plants for natural dyeing, and also for indigo seed production.
In bed 4 I want to start my own breeding experiments with dahlias. I've wanted to do my own plant breeding for ages, and I now have the space to start this. I have dahlia seeds set aside from last year's plants to do this. I'm very excited about this project and can't wait to get started in spring.
Have a wonderful day

Dahlia Profile - Lucky Number Seedlings
Hello friends,
Today we're looking at dahlia seedlings that I grew from Lucky Number dahlia seeds I harvested back in the summer of 2024.
First up we have the original Lucky Number dahlia. It's a peony dahlia with multiple rows of bright pink petals, with yellow centers. Each flower is about the width of my palm. Lucky Number gets to about 1 metre in height with bright green leaves and brown stems.
And here are the progeny of my Lucky Number dahlia.
This first one is a single dahlia with colours of peach and yellow in the petals, and a smaller flower than Lucky Number. The dahlia plant is similar in size to Lucky Number, but the stems are much darker in colour. My hunch is that this dahlia is a cross between Lucky Number and my Mystic Sparkler dahlia in the garden.
The second dahlia is pretty similar to the first dahlia, but the petal colours are a much darker pink, and there is an uneven mottling across the flower petals. The flowers are much bigger than Lucky Number in size, and I think this dahlia is a cross between Lucky Number and a red hybrid tree dahlia that grew in my garden in 2024, from seed that I purchased from NZ dahlia breeder Keith Hammett. The hybrid tree dahlia was bright red in colour with huge single flowers similar to this seedling.
The third seedling is definitely another cross between Lucky Number and the red hybrid tree dahlia. The petal colour is exactly the same as the red tree dahlia, but has rows of petals similar to Lucky Number, and the plant as a whole is similar to Lucky Number in size and colour.
And last up is a Lucky Number seedling that looks like a smaller cross of the third seedling. The flower is much smaller, and the red a bit more scarlet. I think this is also a cross with the red hybrid tree dahia.
It was an interesting experiment to grow seeds from the Lucky Number dahlia, and right now I'm unsure if I will keep any of the seedlings, as space is always at a premium in my garden. I'll make a decision in the coming weeks on what to do with these dahlias, and then tag them for digging up or keeping them once the first frost has passed.
Have a wonderful day
