General Gardening Tips for July

Harvest a winter salad: Baby leaves of kale, beetroot, spinach and silverbeet make colourful, yummy winter dishes.

Deal to heavy clay soils: when planting add a handful of Gypsum in the planting hole before filling with a mix of existing soil and Premium Garden Mix.

Gypsum


Frosty garden? On still, cold nights cover young avocado, citrus and tamarillo trees with frost cloth - available at the local garden centre.

Forward planning: a variety of deciduous shrubs such as philadelphus, the shrub-like Magnolia stellata and the bright Mollis azaleas can be planted now.

Trees & Shrubs

Prune and shape deciduous shrubs such as cercis, crepe myrtles, viburnums, as well as roses.

Plant new season’s fruit and ornamental trees – there’s a variety of great fruit trees being bred for small urban gardens – just check with your local garden centres.

Dwarf Fruit Treet

 

Stake them to two-thirds of their height to keep the root area steady and protect them when spring winds start.

Deciduous trees and shrubs are winter dormant so this is the best time to lift and re-position in your garden.

Lift and divide favourite perennials now – free plants are often under your nose.

Daphne, wintersweet and boronias are just some of the wonderfully scented shrubs that can be planted – preferably near a walkway or a doorway.

Prune deciduous fruit trees and spray with copper and oil mixed together.

Flowers

Sharpen secateurs and loppers ready for pruning roses, which can be started this month.

For newbies local garden centres often hold rose-pruning demonstrations – or there’s always Youtube.

Rose Prunning


A copper and oil spray over pruned roses provides early resistance to disease and disrupts any scale forming on the canes.

Ordering online – it’s the time to order lilies, gladioli and dahlias.

Dahlias from last year can be lifted and divided for replanting in October.

Lilies grow well in pots – choose dwarf varieties.

Regular deadheading, plus a side dressing of dried blood around flowering polyanthus will encourage a long-flowering season.

Rainbow Silverbeet

 

Brighten the winter garden with rainbow silverbeet, giant mustard, ornamental kale and edible calendula flowers all have great colour in winter.

It’s not too late to put in garlic bulbs – break them up into separate cloves and plant at twice the depth with the pointed end facing upwards. Onion seed can be sown from now on too.

Renovate your raised garden beds to get them ready for spring growing by adding fresh Garden Mix or digging through some Revital Organic Compost and Morganics Organic Fertiliser.

Now is a great time to fix any leaks or drippers in your irrigation systems.

Winter lettuce varieties: a mix of frilly, cos and ‘Great Lakes’ are all hardier types that cope with cold temperatures, provided they get some sun.

Brighten up winter salads by growing a range of microgreens such as kale, komatsuma, spinach, sorrel, and pea shoots.

If the weather is too wet, try growing sprouts in a jar in the kitchen to add to salads.

Seed Potatoes

 

Prepare the potato patch – dig in lots of compost and sheep pellets so the soil is ready for when you’ve sprouted the seed potatoes.

Keep seed potatoes in dry cool areas – garage, carport, under eaves to begin sprouting. Planting is generally 6-8 weeks from now.

Make sure broad bean plants are well-staked.

Planting of kale, cold hardy lettuces such as cos and sowing of radishes and carrot seed can take place now - try our Premium Garden Mix for premium results!

Strawberry Plants with Straw


The first of the summer crops need attention: Place sheep pellets and straw around strawberry plants; place a light layer of compost over asparagus and place seed potatoes in a dry area to sprout (under house eaves is good).

Spray pip and stone fruit trees with copper and oil mixed together to provide resistance to fungal infection.

July Lawn Care

Sharpen the blades of your lawnmower! There's never been a better time.

Lawn care


For best results to pep up winter lawns apply our Prolawn All Purpose Fertiliser - a quick-acting fertiliser ideal for a late winter boost. This fertiliser is good around the garden beds as well.

Landscape Project Ideas for July

Landscape a weed-covered bank

Gaining control of a weedy bank is one of the most satisfying achievements in your garden.

We recommend Weed Safe Pro Weedmat and Weedmat Pins. Simply cover the bank with matting and pin it in place.

Plant desirable NZ natives or other hardy plant species by cutting a hole in the matting and incorporating Garden Mix in the planting hole as you go.

Condition your soil

Condition soil by adding compost and sheep pellets, or try our Aquaticus Soil & Plant Conditioner.

Compost breaks down clay and enables the soil to retain moisture, building resilience ahead of hotter weather.

Sheep pellets add nitrogen and also work to improve soil texture

Make a winter bird feeder

Winter Bird Feeder

A birdseed pudding is easy to make: take birdseed mix, melted lard and a bit of honey, shape it into a ball and place in a netting bag.

Hang it high in a tree where the birds feel safe enough to get to it.
