March in my vegetable garden

What to do in the vegetable garden in March in Melbourne (Australia)

March in My Green Garden

After the hyper-growth over summer, some plants are almost finished and so there will be a lot of clearing up.

  • The tomatoes are still bearing but some are slowing down. The determinate varieties (such as the Roma) will be pulled up soon as they won't continue to flower once their fruit has finished. I always like to check the roots when they come up to check for tell-tale signs of root-knot nematode. If they come up without the knobbly bits, the soil has been clear.
  • However, when the beans are ready to come out, I prefer to cut the plants to the base and leave the bean roots to rot in the soil. They do have knobbly bits but on the legumes, these are good for the soil instead as they are nitrogen-fixing nodules. Some of the beans did escape my picking and are getting fatter. I can either let them dry on the vine to save as seed or to use as dried beans; or I can pick them and peel off the green outside which will be quite tough and pod to cook the fresh beans inside.
  • I’m battling white fly and powdery mildew, but really, my attitude is to wave the white flag and accept that this happens in Melbourne at the end of the growing season in my garden, regardless of what I try to do anyway. There are ladybirds galore feasting on the powdery mildew of the cucurbits, so I’ll let them enjoy them while the plants are still producing. Of course, when I do get rid of these plants, they will go to the green waste bin for collection, rather than in my compost heap.
  • I will endeavour to grow some lettuce from seed in punnets, but I’ll also let nature take its course because I’d left some to go to seed and new seedlings will soon be popping up. I’ll just have to clear up the soil in the meantime to give them some space to grow. As the soil cools, the lettuce seed might sprout naturally. This goes for the coriander too after some autumn rain and cooler weather.

      And then planning! This time of the year, once the summer crops are out, I’ll sit down and plan the winter garden. I always aim to rotate my crops. At the very least, I’ll make sure that broccoli doesn’t go in where it did last season.

      Then there’s soil rejuvenation. Time to empty out the compost bins once again to rejuvenate the soil after the excesses of mega-production over summer. Some nice gentle cow poo won’t go astray and maybe even some mushroom compost where the brassicas and the garlic will go. Can't see this happening before the end of the month as the plants are still in good production but planning can always happen.

      Speaking of garlic, it’s still a bit early to get it in but I will pop several bulbs in the vegie crisper section of the fridge to simulate the cold needed for larger clove development. If you've got no garlic to plant, get some from an organic greengrocer, at a farmers market or good nursery. In the meantime, once the heavy feeding vegies are out (tomatoes, zucchini, cucumbers, eggplant) the soil can be prepped a bit in time for the garlic. Around Easter is my target to get it in, but you put it in as late as the June solstice in Melbourne. For detailed notes on getting great garlic, click here.

      My seed-raising frame will come into use again soon to get some winter veg sown before they are ready for the garden. I sow and leave the seedlings to sprout indoors as they won't germinate properly if it's too warm, but take them outside once germinated to get some gentle morning sun until the soil is ready to take them ie when I've cleared out the summer crops and prepared the beds. Broccoli, kale, cimi di rape, silverbeet, spinach and spring onions will go in this way. Broadbean seeds will go directly into the soil, as will beetroot, carrots and radish. Phew! I’m exhausted just talking about it all…

March in the Kitchen of My Green Garden

Preserving and cooking with more tomatoes which are ripening fast. I like to make jars of peeled and chopped tomatoes using a bottling/heat preserving technique. Dead-easy if a bit messy. I will also make jars of a simple ready-to-pour pasta sauce using the excess ripe tomatoes.

More basil = more pesto.

If the zucchini fritters, zucchini slice, zucchini pasta and zucchini chocolate cake is starting to feel a bit repetitive, I will make some more zucchini under oil. This preserve keeps well and is delicious.

Olives might be starting by the end of this month too...
