Winter Vegetables

Autumn. Warm Days, cool nights. Perfect for vegetable planting.

 

By now your vegetable patch has been freshly composted and manured. It’s just waiting for you to plant out.

The basic cool season vegetables that I find grow well in most areas are –  broccoli, beetroot (my favourite), cabbage, cauliflower, leek, onions, shallots, silverbeet, spinach, snow peas, strawberries (my other favourite), peas, kale and rhubarb. 

 

If you don’t get a frost or you can cover your vegetables - beans, lettuce, capsicum and tomatoes can also be grown.

 

If you get really cold you can give brussels sprouts a go.

This is the basic vegetable range; there are so many different variations on these classic cooler weather vegetables.

 

In seedlings alone you can get about four different versions of broccoli. 

 

If you start using old fashioned open pollinated seeds the list can be endless. 

If your vegetable patch consists of a variety of different sized pots don’t worry, there is a large range of dwarf vegetables available in seedlings and seeds. 

 

Leek, lettuce, capsicums, shallots, silverbeet, spinach, snow peas, strawberries, peas and rhubarb all grow well in pots without needing dwarf varieties.  

 

The secret to growing any vegetables in pots follows the same principles as growing in the ground. 

 

Start with the best quality soil or potting mix, mulch with an organic material (I like organic sugar cane mulch that is free from weeds), fertilise with a complete organic slow release fertiliser and liquid fertilise fortnightly with a complete organic liquid fertiliser. 

 

I like using the Plant of Health range of fertilisers – Organic Link and Triple Boost and Searles' range of garden soil and potting mix - Peat 80 Plus

I find the cooler months are the best time for growing herbs.  Nearly all the herbs are available now. Herbs grow well in the garden or in pots and most herbs can be grouped together in pots to make mini herb gardens. 

The best thing about growing cool season vegetables is that it’s usually too cold for the pests to be out and about.  If you do get a few pests a pyrethrum based spray or one of the new organic sprays like eco oil or eco fend work well.  Mildew and mould is a common problem during wet winters - copper spray (some are considered organic) can be the best solution. 

 

I have heard that having pretend white butterflies in your vegetable patch not only looks pretty but helps deter moths.

Remember though the healthier the soil, the healthier the plants and the less likely you are to get problems. Now get outside and get dirty!

Bloomin' Fabulous

A common question I am asked is "why didn't my fruit trees fruit profusely or if they did why was the fruit misshapen?" Or "why didn't my camellias and azaleas flower as well this year?" Or even "why are all my coloured foliaged plants like crotons and dracaenas losing their colour?"

The answer is usually quite simple - Your garden just needs some TLC and a little Potash!

Potassium Sulphate or Sulphate of Potash is commonly called Potash.  It is an essential element necessary to the lives of all plants.

It aids in disease resistance and frost protection by strengthening the plants cell walls.  It helps in seed and root development. It encourages strong new growth and helps with the formation of flower buds and fruit.

Potash can improve the quality and the colour of flowers and enhances the formation of proteins and sugars in fruit. Potash can even help plants with slender stems and large flower heads such as Iceland poppies and gerberas hold their heads erect.

Potash defective cues can be seen in a number of ways in your plant. Your plants might be showing signs of overall weakness especially in its stem.  It could have yellowing leaf margins and grow more slowly.  It could also be disease prone and its fruit and flowers will be small and poorly coloured and sometimes tasteless.

Don't confuse a potash deficiency though with an unhealthy plant. Always make sure you have given your plant some complete slow release organic fertiliser like Organic Link first.

It seems that many Australian soils are low in potassium (potash).

Complete fertilisers, whether they are chemical or organic, usually contain potash.  Organic Link contains potash. An N:P:K ratio can usually be found on the fertiliser label. A very quick explanation of the N:P:K ratio is - N stands for Nitrogen (greening, growing), P Phosphorus (roots) and K Potassium (fruiting, flowering).

If you use mainly a manure based fertiliser like blood and bone or chicken manure you will need to add potash as these products don’t naturally contain it.

Potash also is available by itself in a liquid form and a granular form. 

The liquid form is added to water and used as a foliar spray. Used like this it is quick acting but not long lasting and needs to be repeated on a fortnightly basis. This is best for promoting flowers especially on annuals.  I use Plant of Health's Potash and Silica. 

The granular form is added to the soil and watered in.  The granular is slower acting but lasts a lot longer.  This is best for correcting deficiencies, promoting fruit and stimulating coloured foliage. We use Searles' Potash.

This weekend I want you all to get some granular potash and go a little silly in your gardens. Your winter blooming plants like camellias and azaleas will love you and your citrus trees will adore you.

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 50 degree day was just in our imagination. 

This is what it feels 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 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 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.  The green manure seeds packs contain a mix of seeds.

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.
