Plant from seedlings: Asian greens, broccoli, cabbage, garlic, kale, mustard, shallots, silverbeet, spinach
June will mark the shortest day of the year, which means a lot less sun for our gardens. The growth of our vegetables will slow down dramatically.
Bear this in mind when sowing and planting this month, and seeds will germinate faster when started in trays.
You won’t see any big growth changes until the soil warms up, closer to spring, especially if you are in colder areas of NZ.
If your area is prone to frosts, keep your salad greens undercover and choose cold-hardy varieties, or sow other hardy leaves such as mustard.
Keep Your Plants Warm and Your Soil Protected.
Keeping your soil covered with mulch or a green manure crop will stop the rough winter weather eroding it and keep those nutrients locked in and the soil organisms happy.
Choosing a homemade mulch first helps keep costs down in the garden.
Plants around your garden that need to be pruned or trimmed? Chop up the trimmings to make instant mulch. Grass clippings work wonderfully as well, as do pine needles and chopped seaweed.
Shredded leaves are always a fantastic option too, as is leaf mould.
Green Manure Crops
Green manure crops are seeds that will create a cover over your soil so it’s not left bare in winter. This keeps the micro-organisms and bacteria under your soil fed and happy. It also suppresses weed growth and helps keep the nutrients in your soil.
Some green manure seeds also provide nitrogen as some are ‘nitrogen fixers’. Seeds such as blue lupin, Lucerne, and broad beans are nitrogen-fixing which means they take up nitrogen from the soil and ‘fix’ it in these small nodules at the end of their roots.
Come spring, you can chop down this cover crop and let it break down back into the soil. The nitrogen from these little nodules will then be released back into the soil in a form that other plants can then take up and absorb.
Compost
Any spent plants you're not using for mulch can be added to the compost
Chopped spent plants, dried leaves, grass clippings, fruit and vegetable scraps, manure, shredded paper, pet hair...this can all go in the compost.
Every time you add in some fresh 'green' stuff (food, green leaves, grass clippings..) add in some 'browns' too (dead leaves, brown paper bags, shredded cardboard, straw...)
Giving it a turn every few weeks will speed things up. I use a compost turning stick.
Tree Health
Now that the focus isn’t all on planting vegetables, it’s a good time to take care of your fruit trees, especially the deciduous ones.
If your trees suffered from fungal diseases such as a curly leaf, blackspot, or oozing wounds, now is the time to treat them. Fungal spores can harbour over winter and reinfect your trees next season.
Spraying your infected trees with a copper spray (following the diluting instructions exactly!) and once again at the end of winter before the new buds burst can help tackle these problems.
Never mix copper with any other fungicide sprays. As with any fungicides, take care when using them and wear appropriate protection and be cautious with any runoff. Copper, for example, is toxic to fish.
If bugs such as thrips were a big issue you can also spray horticultural oil on your tree which will smother the eggs that are hiding in the crevices of the tree.
Clear underneath your trees too and get rid of any decaying, fallen leaves. More than just fungal infections can hide there, like thrips for example.
Once you have cleared under your trees, give them a good helping of compost and organic matter (aged manure, chopped seaweed, leaf mould…).
Protect your vulnerable trees from frosts, such as young citrus or avocado. You can easily make a frost cover enclosure by hammering in a few wooden stakes and wrapping frost cloth around it when you know it will be a cold night.
In the evening, check if there are clouds in the sky. If it’s a clear night, it will be a frosty, clear morning too.
It’s a good time now to plant fruit trees too.
Stay warm, and happy gardening!

Eilen, I love your blog and always look forward to it arriving in my inbox. What a good mum you are to feed your two energetic boys with real food, and food you have grown yourself. I'm a wife, mother, and grandmother to 16 grand-babies . I have grown my own food for ever. I grew veg in pots when my first son was born as we lived in a flat. The first thing I did when we bought our own home,was to dig up some ground, put down some compost and put in a vegetable garden. I feel sad when I see, today, what some mothers feed their children, and then wonder why they have behavioural and learning problems. Keep up the good work, and keep those little boys bouncing with your lovely homegrown goodness.❤️ Julia.
