Mike and Wendy Robinson-Koss have been operating Otway Greening since 1995 and have accumulated lots of knowledge and expertise over that time on how to revegetate the land.
Otway Greening is a plant nursery specialising in Otway indigenous trees & understorey, located in Deans Marsh, Victoria.
Mike and Wendy love to share their wisdom and practical hints about growing plants that are native to the Otway Ranges.
Otway Almanac 2018 has pleasure in posting their tree planting calendar.
Tree Planting Calendar For the Successful Grower
It has been proven over and over that weed or grass competition is the main cause of tree seed- ling mortality. In other words, the trees die before they become established because they are com- peting with the surrounding vegetation for available soil moisture. By keeping the area around the young tree seedling weed free, the seedling will grow without competition and by the rst summer will have its roots into the moist subsoil helping it survive until the rains begin again.
In years of drought or exceptionally hot conditions this pre planting weed control could be the one factor between success and failure. Weed control is the most important step in a successful reveg- etation program.
The other points to consider now before you’ve picked your trees up and are ready to plant are:
1. Do you have rabbits or hares or other animals on your property that nd tree and shrub seed- lings tasty such as sheep, wallabies, kangaroos, crickets, magpies, etc?
If the answer is yes then you should be controlling the feral critters and fencing out the others. If you’re not sure, look for burrows, droppings, or rabbit scratches in the soil. Go out at night with a spot light and look around for animals. You will soon see them in the light and you can work out what they are. Ask questions of your neighbours of their experiences- do they know of browsing animals in the area and if yes what are they?
2. What species of tree/shrub are you going to plant on your property? What are your needs/ wants?
c. Attracting birds and wildlife.
3. When should you be planting your trees/shrubs?
The Plan of Attack for Successful Revegetation 9-12 months prior to planting
1. Start your weed control program now if you have highly competitive weeds such as phalaris, blackberry, paspalum or bracken.
2. Order your plants well in advance of planting.
3. Begin your vermin control program now!
4. Wallabies and kangaroos can be a big headache locally so check with tree planting neighbours on their tactics or enquire with the relevant government agency.
4-6 months prior to planting
1. If the ground has been cropped for years or has had cattle on it, the soil may be compacted which may affect root penetration of your native seedlings. Before the soil becomes saturated with autumn rains, pull a single tyne ripper through the soil using a tractor or dozer. Instead of slicing the soil, the ripper will shatter and crack the hardpan layer giving the trees’ roots a chance to ven- ture below the impeding layer. Single tyne rippers can be hired.
2. You will need to control weeds and grasses again when they germinate with the autumn break. This will either be with mulching or with chemical control (glyphosphate). Many people use a knap- sack and spray spots with the herbicide where the tree will eventually be planted.
3. Mounding of the soil might be important if your plantation will be in a very wet or salty patch
4. Don’t forget to get your fencing started (and hopefully completed). If you are using a fencing contractor, you’ll need to have booked the contractor well in advance.
5. Do you need to order tree guards? Most guards only protect the plants from rabbits.
Wallabies can’t be guarded against unless using expensive wire mesh or tall tube guards. Wind can be limiting factor in extremely exposed areas however in most situations guards are not necessary against wind.
4 weeks prior to planting
1. If you’re using herbicides to control weeds you should be spraying now. * If you sprayed glyphosphate in the autumn you have a choice now. You can just spray glyphosphate by itself (which will kill any weeds that have germinated since autumn) or you spray a mixture of glyphos- phate and simazine (or other pre emergent herbicide). A pre emergent herbicide provides some post planting weed control by killing off germinating weed seeds. The success of this herbicide depends a lot on your soil type, rainfall near the time of application, and rate of application. (*Some landowners only apply herbicide once, 3-4 weeks before planting. This is usually the glyphosphate/simazine mix. This can be successful if the existing grass is short and doesn’t have highly aggressive weeds like phalaris or kikuyu).
2. Fencing should be complete prior to planting. Stock should not run over the ground once simazine has been applied.
3. Contact Otway Greening to make sure all your plants are ready and arrange a pick up date.
4. What tools will you need to plant the trees/shrubs. You can hire Hamilton tree planters (for for- estry tubes or Lannen cells); Potti Putki tube planters and kidney baskets (for Lannen cells) from Otway Greening. Organise them now!
1. Pick up your order and give the plants a few days to get aclimatised to their new home. All our plants are grown out of doors so there will be no problems with the plants being too green.
2. If your plants are in cells (Lannen 81 or 63 trays) maintain a watering schedule. The seedling roots have claimed most of the space in the cells so the cells can dry out quickly especially on warm days. Make sure your plants are saturated for planting using a sprinker or wheelbarrow lled with water.
3. Have you organised family and friends to be labourers on the day? Work as a team with even the kids helping.
4. If the ground is wet (and your plants are too) it won’t be necessary to water the plants in the ground. Just rm the soil in around the plants so there are no air pockets to dry out the seedling.
5. Make sure to have fun!
6. You might want to keep records of where and what you planted. This might be useful informa- tion later on when ordering more plants.
7. After planting, PLEASE return your Lannen trays to Otway Greening. They are very expensive to buy and we need to reuse them every year.
8. When returning your trays talk to us at Otway Greening about next year’s project because it won’t be long before the December deadline comes around.
