March in the Garden
March
The start of autumn …
This month sees the beginning of the “season of mellow fruitfulness” when the bounty of summer’s flowers, fruits, and veggies is almost finished, the sun is losing its intensity, it’s less humid in the northern states and days are gradually shortening. There’s an overall feeling in the air that we’ve managed to survive the challenges of another summer.
Summer’s seasonal flowers and vegies and the last of the fruit crops are coming to an end with the onset of cooler days and crisper nights. It’s a great time to make jams, sauces, relishes and preserves with the abundance of produce available, to tide you over the less productive months ahead..
As flowers and vegies fade, pull the plants out, dig over the soil, add compost and fertiliser and start preparing to plant Winter and Spring flowers, bulbs and edibles.

Vegetables
What to plant now
Sowing seeds or planting out seedlings of Winter veggies can begin from mid-month. Your crops will get a good start before colder weather slows down growth.
In temperate to cool temperate areas, sow seeds or plant seedlings of:
- Broccoli
- Brussels sprouts
- Cabbage
- Cauliflower
- Chinese cabbage
- Kale (including Tuscan kale or cavallo nero)
- Carrot
- Leek
- Parsnip
- Spinach
- Spring onion
- Silverbeet
- Turnip
In warm regions, sow or plant:
- Beetroot
- Broccoli
- Cabbage
- Carrot
- Cauliflower
- Peas
- Silverbeet
- Spinach
- Okra
- Swede
- Soft herbs – parsley, coriander, basil
What to harvest now
As Summer fades into memory, many vegetables will still have the last of their crops ready for picking.
- Leafy veggies like lettuce, rocket, silverbeet, spinach and rhubarb should be picked/cut and either eaten while fresh or blanched/cooked for freezing.
- Beans, zucchinis, capsicums, chillies and cucumbers may be snap-frozen or pickled.
- Ripe tomatoes may be turned into passata, sauce or chutney or simply peel, cut up and freeze in meal size portions (use within 6 months). They can also be bottled (preserved) for use over Winter. Green tomatoes are unlikely to ripen at this late stage, so make them up into pickles.
- Pumpkins should be left on the vine until the plants die, usually after the first frost of the season. Cut from the vine with a stub of stem attached and store on racking in a cool, dry spot with good air circulation. They will keep for several months.
- Potatoes should be dug before the weather turns cold and wet. Leave them out in the sun for a day to dry then brush off loose soil and store them in a dark, cool place, again with good air circulation to minimise rotting.
Veggie patch tips for March
- Before sowing or planting, dig the soil over to a depth of about 300mm to work in any remaining mulch, then add a generous handful of garden lime per square metre as well as a suitable fertiliser.
- Allow rainfall (or watering) to wash the lime and plant food into the soil before planting preparation.
- Keep new plantings growing strongly with applications of liquid fertiliser for vegetables and herbs such as Scotts Organic Plant Food Ready to Use every two to three weeks
- Water deeply at least once a week if the weather is dry – add a wetting agent to ensure moisture penetrates deep into the soil
- Hand pull or hoe out weeds as they appear – they compete for nutrients and moisture and may also harbour pests that could attack your crops
- Use snail and slug traps or baits to protect young seedlings
Fruit & Flower Beds
What fruits to harvest now:
Most of the summer fruits like apricots, peaches, plums and nectarines will have finished by now but there should still be good crops of mid to late season fruits maturing. These include:
- Apples
- Pears
- Raspberries
- Grapes
- Figs
- Melons (rock and honey dew)
- Mandarins
- Selected oranges
- Passionfruit
- Persimmons
- Pomegranates
- Quinces
What fruit to plant:
Evergreen fruiting plants may be put into the garden now while the soil is still warm – passionfruit vines and citrus among them. Deciduous fruit trees in pots should be left until they are dormant and have lost all their leaves before being transplanted into the garden. Together with new bare-root fruit trees, they are best planted in mid to late Winter. Here's the list of fruit and citrus to consider:
Garden Tasks
What flowers to plant:
- Alyssum
- Calendula
- Chrysanthemum
- Cineraria
- Cyclamen
- Forget me not
- Gypsophila
- Lobelia
- Ornamental Kale
- Pansy
- Sweet peas
- Viola
Garden jobs for the month:
- Pick up and dispose of any fruit on the ground under fruit trees – they may be diseased or harbouring insect pests – don’t put them in the compost bin!
- Remove and dispose of diseased or “mummified” fruits clinging to branches to avoid diseases spreading or over-wintering on trees.
- Cut out and dispose of galls (swellings) on citrus trees to help eradicate gall wasps.
- Tidy up the garden by removing spent flowers and flower spikes from perennials and annuals.
- Dahlias and chrysanthemums may need staking and/or the ties checking to ensure they are not cutting into stems.
Pest Control
- Keep an eye out for aphids, especially on roses, herbs and vegetable seedlings. Use a general garden insecticide like Defender Pyrethrum Insect Spray to control them. Don’t forget to spray the undersides of leaves too.
- Watch for the caterpillars of the White Cabbage Butterfly on cabbage, cauliflower, broccoli and other brassicas. Pyrethrum will assist or try a cabbage dust.
- Newly planted seedlings may be targeted by snails and slugs. Protect them with Snail & Slug Pellets.
Lawn
Tips for March
Summer can be harsh on lawns, especially during drought and heatwave conditions. This month is a great time to repair the damages caused by the ravages of the season just passed.
- De-thatch with a garden rake to remove build-up of dead grass, especially in buffalo, kikuyu and couch lawns.
- Aerate the lawn with a garden fork or you can hire a coring machine suitable for home gardens.
- Top dress with Scotts Lawn Builder Organic Lawn Soil – Topdress Mix & Underlay.
- Water entire lawn area, if permitted, to settle topdress mix.
- Fertilise with Lawn Builder All Purpose Slow Release Lawn Fertiliser, Lawn Builder Buffalo, Lawn Builder Extreme Green Granular or one of the Lawn Builder hose-on equivalents.
- Worn and bare areas may be over-sown with lawn seed to match your existing grass type or patches of instant turf.
