Winter Gardening Tasks for June

 

Cold, damp winter days are now with us, but the garden is brightened with the flowers of camelias and azaleas. New plants are now arriving at garden centres, so an exciting time for planting in the home garden.

Houseplant care 
Time to ‘condition’ your houseplants for the colder months ahead. It may be necessary to shift some houseplants to parts of the home that receive better natural light. Drop back your weekly watering with lukewarm water. With leafy, foliage houseplants, keep misting regularly with lukewarm water. Check your houseplants often for early signs of problems – these are typically related to watering – too much or too little!

Vegetable garden 
Traditional winter vegetables that were planted in autumn can now be harvested including: Asian greens, broccoli, cabbage, carrots, cauliflower, celery, kale, leeks, lettuce, silverbeet and spinach. 
Continue plantings of broccoli, cabbage, cauliflowers, kale, silverbeet and spinach. Old rhubarb plants can now be divided and re-planted into sites prepared with fresh compost. New, healthy garlic bulbs are available and can be planted in a sunny, well-drained position. 

Flowering annuals
Winter annuals are now bursting into flower, including alyssum, calendula, cornflower, pansies, poppy, primulas, snapdragons, stock, and violas. Dead head (removing finished flowers) your flowering annuals to ensure continuous blooms. Brighten up areas in the garden with ‘potted colour’ to provide instant flowering – there is plenty to choose from at your local garden centre. Extend winter-flowering by planting dwarf cineraria’s which flower late winter and into early spring. 

Perennials 
As perennials flourish in the garden, some species become overcrowded leading to poorer growth and less flowering so it’s a good idea to divide and replant them every few years. Remove all the old foliage prior to dividing, and replant into new ‘beds’ replenished with fresh Daltons Garden Time Compost. 

Fruit Trees
Prune your pip and stone fruit trees – this is particularly important with new, young trees. The aim is to establish a strong framework that will support later fruiting. With older trees, there may be more ‘radical’ pruning required to reduce the tree height and to encourage the growth of two-year-old wood that will produce fruit. A ‘clean up’ spray of a copper compound after pruning is completed, should be undertaken. 

Raspberries  
Complete your raspberry bush pruning this month. Remove all but the strongest canes as raspberry plants produce many spindly shoots. Tie the selected canes to stakes or wires.  Remember, canes older than two years usually produce little or no raspberries so best to cut those back. 

Rose care 
Traditionally June was the accepted month for pruning roses, however as the climate warms, it may be wise to wait until late June, early July before beginning this important task (dependent on where you live). Continue adding compost around existing roses and when planting new specimens. New-season roses will appear in garden centres in June and July.

Ornamental trees and shrubs 
As new seasons plants arrive at garden centres, this a great time to add new additions to your home garden! Plan new gardens carefully – read plant labels so you know how large the plant will grow to avoid overcrowding later on. Soil preparation before planting is one of the most important steps to give your new plants the best chance for strong and healthy growth. Prepare the planting site thoroughly by adding in plenty of fresh compost.  

Lawns
Grass growth should have stopped by now, limited mowing will be required over the winter months. Check the lawn for ‘wet’ spots, as these areas may require additional drainage.
