What Seed Do I Buy

When we bought Trevallan nearly 24 years ago our experience with seeds was minimal.

My grandfather always reused his own seed and that was considered normal.

When we bought Trevallan we had three different seed companies in stock and within a few short months most of our complaints came about due to seed issues.

So started a research project into something entirely new for us, using customer recommendations and my grandfather as our test subject!

Very quickly we converted to Eden Seeds.

Very quickly our seed problems diminished and demand for seeds grew until now where we have the Great Seed Wall!

So what were our problems with some of the seeds we used to stock.

• Low germination rates (by experienced growers)

• What grew wasn’t exactly the same as what it was marked as

• Problems with growing past a certain point

• Major problem was not being able to collect seed reliably for future cropping. This was something my grandfather always did. It was very important

We discovered Eden Seeds. Eden Seeds states “aim is to distribute old traditional open pollinated varieties of vegetable seed, preferably old Australian varieties and organically or bio-dynamically grown where possible. We believe they are more nutritious and better tasting, hardy and easier to grow for the home gardener. Old varieties produce over an extended period. Home gardeners obtain relaxation, enjoyment and quality from a most rewarding hobby. Our seeds are the old traditional open pollinated non-hybrid varieties and have no chemical treatment, and no genetic engineering.”

This sounded great to me but first I needed to understand what that all meant!

Hybrid Seeds

Hybrid seeds are produced through careful pollination of two specific varieties by human intervention. Normally, this highly selective plant breeding is done to bring together two traits in each of the chosen varieties so that the resulting seed has both of the traits
An example may be a cabbage that grows huge but is susceptible to disease. A smaller-growing cabbage is very disease resistant. They combine the two and boom a large cabbage head that is disease resistant. Usually, you can’t reseed these plants as the seeds may not contain the characteristics of the hybrid plant.

Positive of Hybrid Seeds Hybrid seeds are believed to have better disease resistance and perform better in terms of more fruits, flowers and vegetables produced.

Negative of Hybrid Seeds Hybrid seeds tend to be more expensive to buy due to the specialized pollination process and the seeds you collect from them will not grow the same plant next year and, in some cases, have been bred so that no plant at all can grow from the seeds of a hybrid plant.

Non-Hybrid

Non-hybrid seeds, or open-pollination seeds, are naturally pollinated naturally (bird, insect, wind). They come in a wealth of different varieties and produce seeds that grow into plants with similar characteristics as the original plant. Over successive generations, non-hybrid plants may also adapt to local growing conditions, making them stronger plants, and ultimately less susceptible to local pests and disease.

Using non-hybrid seeds has another advantage: you’re helping preserve the biodiversity of our food supply. Many of the rarer “heirloom” and “heritage” seed varieties would be extinct were it not for the efforts of non-hybrid gardeners and farmers

Genetically modified organisms (GMO)

GMO seeds are produced by genetic engineering, altering the genetic material of an organism. This is different from hybrid seeds that are produced by cross-breeding of two varieties through artificial mating

 Organic vs Non Organic

You can buy Organic hybrid seeds and organic non hybrid seeds You can not buy organic GMO seeds. Many people tell me that they buy their fruit and vegetables organically so they just reseed their garden from that. You can buy hybrid organic vegetables and seed. This means while your seed is organic your vegetables may not regrow true to the plant you purchased.

Australian Organic Laws are very strict, always look for the Australian Organic Certification stamp when buying organic products. In Australia, the Australian Certified Organic (ACO) standards require organic seed producers to use organic practices and to undergo an annual certification process. The certification process for organic seeds involves ensuring the land is free from synthetic chemicals, using organic methods for seed production, and processing the seeds without synthetic chemicals.

No Chemical Treatment

Untreated seed is classed as ‘clean’ seed and has not been treated using any chemical, biological, or physical method. While untreated seed can be grown under organic conditions, the seed crop was not grown under Certified Organic Conditions. As the Certification process can be lengthy and costly many farmers choose the no chemical treatment option. Untreated seed is a popular alternative to organic seed.

Bio-dynamic

Bio-dynamic seed crops are grown in living soil within a diverse thriving ecosystem. Not a sterile environment such as under growing houses or single crop acres. Seed produced from this growing environment is bred to thrive in organic/bio-dynamic growing conditions.

Best Seed?

A lot of information to cover there but as you can see buying open pollinated, no chemical treatment, bio dynamic seeds is dare I say it ‘the best option’ for starting your thriving vegetable garden.

Eden Seeds

We have chosen Eden Seeds as they are a great Australian company with an ethos we align with. They stock both Organic and no chemical treatment, Bio dynamic seeds and we try to stock a good range of both. Our Great Wall of Seeds is constantly changing and evolving to supply you with not only the best seed but the best diversification so we all aren’t stuck growing just beans!

Choosing what seed to grow… Well that is another story!

Is Green Manure just really Green Poo?

Wonderful blistering hot days, humidity that feels like we should be living in tropics, rain and winds that blow your roof off then cool days that make us wonder if that 45 degree day was just in our imagination. 

This is what it can feel like to live in Ipswich in the summer. 

How would you fare in this weather? Hot, bothered, quick tempered? 

 I know I've been struggling, the smallest things bother me. 

 If I had a vegetable patch right now, I know I'd be pulling most of it up. 

 If the heat didn't kill everything off, the humidity or insects probably would have. 

In years past when I have had a vegetable patch in summer I have suffered with burnt leaves, white mould all over my cucumbers, tomato blight and then to top it all off grubs in my fruit (from fruit fly stings).

Which is why now, at this time of year I always sow a summer green manure crop. 

Green manure crops are crops grown not to be harvested but instead to be incorporated into the soil before they reach maturity to contribute to the health of the soil. 

It is an old technique of soil management that seems to have been forgotten by many gardeners and farmers. I think it's because we are no longer aware of the proven benefits and cost effectiveness of green manure crops. 

Trevallan Lifestyle Centre stocks Eden Seeds, a seed company that only stocks old traditional open pollinated varieties of seed, preferably old Australian varieties and organically or bio-dynamically grown where possible.  Eden Seeds do a wonderful green manure seed pack that contains a mix of seeds suited to most climates.

Green manure crops contribute directly to the fertility of your vegetable patch through the supply of important plant nutrients. Legumes, for instance, supply nitrogen because their roots form an association with soil-borne bacteria that can transform nitrogen from the atmosphere into nitrogen compounds that can be used by plants. Isn't nature wonderful? It's also just saved you money as now you don't need to add as much fertiliser to your vegetable patch.

Green manure crops can also contribute indirectly to nutrient supply. Just the process of decomposition of the crop aids in making further nutrients available that are already present in the soil but in a form that cannot be used by plants.  After the plants have grown and you incorporate them back into the soil you are supplying vast amounts of organic matter that is usually supplied by organic mulches. Once again saving you money - no need to buy organic mulch. 

Drought resistance can also be improved as a lot of the crops are very deep rooted. Their roots can penetrate the subsoil and open it up. Next season's crops can also obtain plant nutrients from the subsoil once it is opened by deep rooted green manure crops.

 So this weekend get dirty and take out all your hot weather anger on your vegetable patch by pulling everything up and planting some green manure crops. Your winter vegetables will thank you.
