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

Harvesting My Own Sugar Beet Seeds
Hello friends,
Back in the Winter of 2024 I was perusing the Kings Seeds website looking for seed packets to buy for the upcoming spring season. One of the packets I was looking to purchase was Sugar Beet seeds, which Kings Seeds had supplied for many years. As you may have seen in my blog, I grow Sugar Beet plants as a source of my own sugar. You can read all about my Sugar Beet extraction method in this blog post from 2023.
Except there wasn't any Sugar Beet seed packets available on their website. So I contacted Kings Seeds and asked them if they were going to be selling Sugar Beet seeds that year, and they told me they were no longer going to be stocking them. I had a little panic, but then went online to see if anyone else in New Zealand was selling Sugar Beet seeds for the home gardener. Unfortunately, I wasn't able to find any Sugar Beet seed suppliers, and all of the big commercial seed companies were only selling fodder beet for farmers.
So now I was panicking big time. All I had left was one packet of Sugar Beet seeds, and it was only half full. The expiry date had run out as well, and Sugar Beet are biennial, which meant that seed harvesting from any plants was two years away.
Determined not to give up, in Spring I direct sowed all the Sugar Beet seeds I had left, and impatiently waited for them to germinate. I managed to get a small number of seedlings dotted around the vegetable garden, with each plant growing under slightly different conditions, with the hope that some of the plants would survive the two year wait to collect my own Sugar Beet seeds.
A number of Sugar Beet plants managed to survive the first growing season, including a very cold winter with -6˚C frosts, and then started growing again in their second year. The Sugar Beet plants began bolting over summer, and started flowering in February of 2025. By this time the plants were very tall, about 1.5 m high, and were prone to toppling over in the wind. A number of plant supports were erected to keep the plants upright until the Sugar Beet seeds were ready to be harvested.
In late March 2025 it was finally time to start harvesting the Sugar Beet seeds, and I made the decision to harvest them by hand, picking off each of the seeds one by one as they became brown. This long and drawn out period of harvesting the seeds took around two months, and then once they were nice and dry, I stored them away over this winter.
Now I have my own Sugar Beet seeds to use year by year to make my own sugar, and to collect my own seed in Autumn, whenever I need to. And I'm also pleased to say that I have enough Sugar Beet seeds at the moment to sell my excess to other home gardeners through my small business Hearth & Oak. If you are interested in buying some of my Sugar Beet seeds so you can grow your own Sugar Beet, and then collect your own Sugar Beet seeds in the years to come, please follow this Sugar Beet seed packet link to my Felt Store.
I had not intended to use this blog commercially to sell anything through my small business Hearth & Oak, but the thought of home gardeners in New Zealand not having access to Sugar Beet seeds and plants in the coming years, was too much to bear. Rare and interesting seed varieties in New Zealand deserve to be saved, and this is my attempt at doing this for Sugar Beet at least. I hope that if you do buy some of my seeds, my blog posts on Sugar Beet will help you grow your own plants, and then collect seeds, so that you can grow Sugar Beet every year.
Have a wonderful day

Sowing Ranunuculus Seeds
Hello friends,
Three weeks ago I finally got around to sowing the ranunculus seeds I bought from Bud & Bloom back in January. The seeds don't germinate in hot weather, so I had to wait until late March when we start to get cooler mornings.
I pulled out my new seed sowing tray protector and got to work. I'm so pleased that I invested in buying it earlier this year, as it cuts down on mess big time, and it's so much easier to sow seeds.
I sowed one seed per cell, and gently covered each ranunculus seed with vermiculite as suggested in the instructions that came with the seeds. I gave them a good watering and stored all the seed trays undercover in the woodshed where it is cool for most of the day.
Now came the patiently waiting part, as ranunculus are notoriously slow at germinating, usually taking 2 - 3 weeks to germinate. Each day I checked on the seed trays and kept the vermiculite damp.
Two weeks after seed sowing, a single ranunculus seedling popped it's head above the vermiculite, and then another and another over the next few weeks.
Quite a few seedlings have come up now, and they are slowly growing in their seed sowing cells. Over the coming weeks they'll grow their underground root systems, and then as the weather gets even cooler, the plants will grow more leaves. I can't want to see lots of ranunculus plants flowering in spring this year.
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
