December

December

Before you get that rush of blood about planting some summer crops, remember that December for many can be a time of holiday travel and/or socialising. You need to think if that leaves time to successfully tend a vegetable garden.

Instead, you might consider some more mundane jobs - you could plant a green manure crop (which will probably still need supplementary water but is far more forgiving). This will help set you up for an early autumn planting.

Perhaps consider spending what time you have available installing an irrigation system for your edible beds. Drip irrigation will be better for most edibles than a system using microsprays. Mircosparys tend to encourage fungal problems on plants like zucchinis and cucumbers.

And maybe just get on top of the weeds - not glamorous or much fun, but it will be time well spent.

If you're not in the travel or social butterfly tent, then just be realistic about what you might grow through an El nino summer. We've seen that it's a long time between drinks! So maybe the previous advice could apply to you as well.

The most important aspects of real estate are location, location, location. The most important aspects of gardening are soil, soil, soil. Through this El nino summer, watch for water infiltration into your soil. Use a trowel to dig after watering. Check that moisture has penetrated. If your garden stays hydrated with deep watering it will encourage stronger root growth and bigger, more efficient root systems.

If water is not infiltrating (your soil is shedding water) then try a product like Eco Hyrdate.

If you have loads of lawn clippings (assuming it does remember to rain), take advantage of this resource and make loads of compost to feed back onto your garden.

Alternative crops

Given we live in the subtropics rather than Europe, you might consider which crops you plant to minimise the need for fungicides and reduced workload.

Try:

New Guinea bean instead of  zucchini

Longevity spinach rather than English spinach

Snake Bean rather than Blue Lake

Poor man's bean rather than bush bean

Cherry tomato rather than Grosse lisse

Is it a straight swap - probably not! But it's about being agile and adapting to our changing climate.

Soil wetting

After a prolonged dry, soil can repel water - called hydrophobic in the trade.

Soil wetters have often been discussed, and invariably, someone asks, can I use dishwashing detergent? The short answer I'd give is - NO!

Eco hydrate has been reviewed as an organic product that's safe to use. When used as directed, it will help soils absorb moisture, rather than repel. With other good practices like mulching, and regular watering, soil life will resume the job of building soil for plant health.

Compost tea and weed tea are two home-made organic solutions to overcome hydrophobic soils.

Mulch

Adequate mulch will be key to regulating soil temperatures and moisture levels over the coming months.

Whether you choose lucerne, sugarcane or Emmo's Hay doesn't really matter. What you're aiming to do is add 50 - 75mm of mulch around established plants. By using something like Emmo's hay, you know that soil life will break it down, and it will therefore be feeding your soil.

You'll water less, weed less and keep your soil life pumping. The result will be a productive edible patch despite the weather.

If you're planning on using lawn clippings, throw some old leaves onto your lawn before you mow, to ensure a much more open product that won't mat down as much when used around your edible beds.


Seeds or seedlings?

With generally consistent overnight temps, germinating seeds should be relatively easy at the moment.

The challenge could be at the transplant stage. New seedlings will need to be hardened off before exposing the plants to near 30 degree days.

Seeds are best direct sown. The challenge then is to provide sufficient water to keep them thriving without them damping off. All the harder if you have a busy schedule that doesn't allow you to tend to them daily, or twice daily. Almost impossible with seeds like lettuce that need light to germinate. Deeper planted seeds will be just that bit easier.

Seedlings too, will need care. But they're usually much bigger, and can cope much better with high temperatures.

Whichever way you choose, water your new plants in with a liquid seeweed solution to assist with transplant shock. 

Feeding

Seaweed helps plants in times of stress such as hot summer days. Healthy and well-prepared soil also goes a long way to making your plants more drought tolerant.

Powerfeed contains higher levels of Potassium which strengthens plants - it thickens their cell walls. That makes them more resilient and able to defend against disease. Potassium helps flowers and fruit to form

I use a Powerfeed as a liquid fertiliser, sprayed with a hose-on applicator. No matter what the weather is doing, it will be absorbed by the plant leaves. A great strategy during dry spells.

Raised beds

Raised beds have become very popular for growing edibles. I used roofing iron to contain the beds, and stop the soil slumping.

Raised beds can have large sheets of metal exposed to the hot sun, which tends to "cook" the soil biology in the bed. This can be devasting to growing healthy, organic crops.

I decided to plant out my walkways, with flowering plants, to both shade the metal and attract pollinators and beneficial.

Consider how you can keep your soil life active by protecting it from the sun.

The list above is for Summer planting in the subtropics.  Success will depend on available shade and moisture.

I won't bother with many root vegetables (like carrots) because I can't grow them quick enough to get the flavour I like. Here's a pretty good guide to help you plan the sowing of seeds in punnets or trays, so they're ready for planting out when you're ready - https://www.boondieseeds.com.au/blogs/news/plantingguide Read seed packets to check which seed should be soaked prior to planting.
