Winter Warmers for your garden - by Julie Munn

Winter Warmers for your garden - by Julie Munn

Jullie Munns

Gardening enthusiast, Julie Munn will keep you up to date with tips around the garden.

During the winter months, even though it’s cold and wet, there is still a lot you can be doing to help keep your garden and lawn looking the best it can be.  

Here are a few little things that you can do to keep your lawn and garden the envy of your friends and family. 

Tips on mowing

Now that the weather is cooler, you can lower your mowing height on your Munns Arid Smartgrass and Munns Pixie Sun 'N ShadeTall Fescue lawns. I recommend 2.5cm cut in Winter as this lower mowing height will allow the sun and the warmth into the thatch, improving turf quality.

During Winter I don’t recommend cutting warm season lawns at all. I always set my mower approximately 3.5cm on my Santa Anna Couch and all I cut is any weed, sour sobs etc that may be in the Santa Anna. I would also suggest this practice for other improved couch varieties. I always fertilise my Santa Anna in early Winter. Even though I do not get a 100% uptake of the fertiliser because I live in Victor Harbor, South Australia (we have cool Winters – 12°C -15°C), I do get some greening up and the lawn looks really good during those long cold Winter months when everything else looks grey and bleak. Once again, Munns Golf Course GreenBuffalo Booster or Buffalo Green Lawn Fertiliser are good ones to apply.

Coring your lawn

Winter is an ideal time to get your lawn cored, this can be done with a hand held corer or you can hire a machine or contractor to do the job for you! After coring apply gypsum at 1kg to 2sqm. The gypsum will work its way into the core holes and improve drainage. You could mix your lawn fertiliser with gypsum and apply at the same time and water in immediately.

Always cut your lawn and catch clippings before fertilising. Don’t forget to check mower blades as sharp blades cut the lawn “cleaner”. Try not to cut lawns when they are wet. Apply fertiliser while it is raining and save water.
Apply Munns Weta-Lawn and Garden during Winter. It’s once a year application, let the Winter rain water it in for you!

Fertilising your lawn

Cool season lawns can be fertilised during Winter as these grasses are evergreen and are growing 12 months of the year. Cool season lawns are: Tall Fescue (Munns Arid Smartgrass and Munns Pixie Sun 'N Shade), Kentucky Bluegrass, Rye Grass and Chewings Fescue. These grasses are in Golf Course Green and Houndog Lawn seed mixes. Don’t fertilise if the temperature is below 15°C.

A good fertiliser to use is Munns Golf Course Green Lawn Fertiliser. This is a wonderful organic based fertiliser containing Munns organic Weta-Lawn and Garden. Look for the “Golf Course Green” on the pack. Once again, if you prefer a liquid fertiliser use Munns Organic Lawn Booster.

Fertilising your garden

Munns Betta Bloom Fertiliser is available in 5kg and 10kg bags and 2kg box, which includes a free measure scoop. The 5kg will feed 50 established roses or 100 potted roses. It is also ideal for tomatoes, vegetables, citrus and stone fruit and contains our organic wetting agent.

Betta Bloom can also be used on the following:


Betta Bloom can be used on tough natives like Bottle Brush, Melaleuca's, Lilly Pilli's etc but on the smaller softer types with the lower Phosphorus it would be suitable on the more general hardy natives but would be wise to feed with care. In most instances it is not the fertiliser but the plant it’s being used on.

Azaleas and Camellias:

Betta Bloom can be used on these plants but since azaleas are gentle feeders they will need less. Camellias can be fed twice a year.

Other general garden plants:

Just about all other general garden plants can be fed 3 times a year with Betta Bloom. With new seedlings once their established, a side dressing prior to the first flowers gives bigger and more flowers. Also feeding bulbs prior to flower appearance and again before the flowers finish to build up the bulbs ready for next seasons flowering is a good tip. When planting out potted plants, apply to the soil surface after planting between half to one scoop depending on the plant size.

Bare root plants:

When planting any bare root plants especially roses, do not apply for the first 6 weeks then start a feeding program.  

Potted plants:

Betta Blooom is also great on potted plants, the smaller the pot the less is needed to avoid burning. On large pots a good application 3 to 4 times a year is recommended, water well after any application to either the garden or pots.

David Cooper’s tip: Never apply any fertiliser to dry soils, always water well first.
