- I - 2- DRYANDRAS AT MY PROPERTY, FRESHWATER CREEK, VICTORIA
I have a 31 ha farm which has a g e n t l e s l o p e t o t he North. The s o i l v a r i e s from almost pure sand i n t he south t o b a s a l t der ived i n the north. The house and most of t he garden i s s i t u a t e d i n between i n an area where the 25 cm deep s u r f a c e s o i l i s a medium loam and o v e r l i e s a r a t h e r heavy c l a y which becomes q u i t e puggy when wet. B a s a l t rocks appear a t a depth of about 2m. The a r e a of about 4 ha around t h e house i s surrounded and divided by windbreaks of a n assortment of bushy p l a n t s of var ious indigenous spec ies and numerous r e l a t i v e l y low growing euca lypts . Most of the p l an t s i n the garden grow on e l eva t ed beds usua l ly i n c l o s e proximity t o the wind- breaks. A l i t t l e over $ of t h e beds a r e between 30 and 50 cm high and c o n s i s t of coarse g r a n i t i c sand which does n o t compact. The remainder, up t o l m , c o n s i s t of c l a y m a t e r i a l s excavated from road workings and housing p ro j ec t s and a r e covered wi th 15 cm of coa r se g r a n i t i c sand.
The average annual r a i n f a l l i s 540m and is spread f a i r l y uniformly throughout t he year . Only a l imited amount of dam water i s ava i l ab l e f o r watering. The ph of t he s o i l l i e s between 5.5 & 6.0.
Before the windbreak t r e e s grew most banks i a s p lan ted a t normal s o i l l e v e l s succumbed due t o poor drainage and a high water t a b l e i n win ter and spring. The mature windbreaks have g r e a t l y lowered the water t a b l e so much so t h a t t he s u r f a c e s o i l near the t r e e s b a r e l y becomes moist even i n spring. The r a i s e d beds have f u r t h e r enhanced t h i s e f f e c t so t h a t shrubs near the t r e e s grow very slowly and need some d r i p p e r watering i n a dry summer (such a s t h i s one, 1988). Apart from t h i s t h e remainder receive l i t t l e supplementary water some none a t a l l . The garden has been extended t o l a rge a r e a s around two fenced off dams. Here t h e s o i l i s heavy bu t very wel l drained. Some banksias and dryandras s t r u g g l e with the weeds, grow slowly and even flower.
Nearly a l l my dryandras and a l l the 60 o r so spec i e s of Banksia have been r a i sed i n my nu r se ry from seed. I use a mixture of 3 p a r t s coarse p e r l i t e t o 4 p a r t 6 m minus p ine bark and 4 p a r t 6 m minus r o t t e n hay, both of which have been s t e r i l i z e d by heat . The seeds a r e placed on top of t h i s and covered wi th 6 m minus g r a n i t i c sand. The pots a r e placed i n f u l l sun and watered every morning - no fung ic ides have been used s ince convert ing t o t h e use of pine-bark.
The seed l ings , a t f i r s t growth of leaves , a r e po t t ed ou t usua l ly i n t o 12.5cm p l a s t i c po ts and a f t e r 2 weeks i n a shade house placed i n t h e open sun. The p o t t i n g mix is 5:3:k of p ine ba rk , coa r se sand, lignum pea t and the t r a c e elements and f e r t i l i z e r l e v e l s used a s those recommended by Aus t r a l i an P l a n t s , June 1987 except t h a t low o r zero phosphorous Osmocote i s used. Watering i s done by micro je t s and t h e d u r a t i o n and time is s e t on a R a i n j e t c o n t r o l l e r . Some p l an t s d i e from unknown causes but most a r e planted ou t i n t o t h e r a i s e d beds where the ma jo r i t y t h r ive . (Unfortunately i n one small a r ea Dryandras hewardiana, mucronulata a s we l l a s a few banksias a f t e r 4 years of v igorous growth and good d i s p l a y s of f lowers died r a t h e r suddenly. Other banks ias and dryandras i n t h e same a r e a a r e s t i l l th r iv ing and f lowering) .

M a g a r e t P i e r o n i
-% - A NEW METHOD OF GRAFTING NATIVE PLANTS
r
Merv. Hodge, Queensland Region
About four years ago I was encouraged by a close friend to try grafting
as a method of increasing the reliability of some of the more difficult
native species in my area.
I followed his method of placing a small plastic bag over the scion
and sealing it just below the graft. My results steadily improved
with experience and I began to experiment with different methods.
\
The material used to bind the graft is a plastic film called "Nescofilm"
which is available in rolls of 40 metres by 10 cm. This film has the
advantage that it will break down in sunlight so that it is unnecessary
to remove it when the graft takes.. It also stretches so it is not
necessary to remove it and rebind the graft. However, there is a limit
to what has been stated because if too many layers are applied, the
breakdown and stretching could be affected.
On a number of occasions I noticed that if a dormant bud of the rootstock
was included in the binding of the graft, then it would eventually
grow and break through the tape. This gave me the idea that possibly
the scion might do the same if right conditions prevailed.
The methods used by other growers required that some leaves be left on the
scion. I reasoned that the best way to promote the growth of dormant buds
was togo against convention by removing all of the leaves. I then reasoned
that, if the whole scion was tightly bound with a single layer of tape,
then the buds might break through.
In the first trial I used an unnamed Brachychiton sp. scion onto B. acerifoliurn
rootstock and Dryandra fraserii scion onto Banksia integrifolia rootstock.
The former was almost a certain success but the latter was a little more
adventurous.
The Brachychitons were the first to take and some burst through the tape
in less than two weeks and continued to grow without any further assistance
beyond the normal watering etc. The Dryandras were slower to take but
eventually did break through: Only a couple of the Dryandras took, but
I was satisfied that the method was successful and that I should try more. 1
Since then, I have successfully used this method on the following:
Hakea multilineata I1 petiolaris II victoria
. 'cristata II crassinervia I1 corymbosa 11 c lavigera
Grevillea dryandrii I I stenobotrya II bipinnatifida

Grevillea robusta I I
I I t t 11
I I I 1 11
II ' Ivanhoe ' I I
I1 'Royal Mantle' 11
Kunzea flavescens II
Some of the above were tried simultaneously with the bag method, but at this
stage I would not say that one method is better than the other, but there
is reason for cautious optimism.
I have lost plants because of fungal attack on foliage of the scion using the
bag method. There is quite a build-up of condensation in the bags and
this can encourage fungal attack. In addition, there is need for hardening
of the foliage of plants by gradually opening the bag over a number of
days.
This was evident recently when I tried to graft Baeckea 'Winter Pink' onto
Kunzea flavescens. I used the bag method on 12 plants and only one using
my method. I tried only one because of the time taken to remove all of
the fine foliage and I doubted that the B. 'Winter Pink' would be strong
enough to break through the tape.
The end result was that all of the plants using the bag method were lost
just after the gradual removal of the bag. The one that was fully tapes
over the scion broke through the tape and is still growing vigorously.
At the time of writing, a number of other plants are on trial and many look
promising. One of these is Grevillea pritzelii scion onto G. robusta stock.
Both methods were tried. The foliage of the two plants, using the bag
method, has blackened and it looks as if both are dead. Two plants, using
my method, have'started to break through the tape and look healthy. All
were grafted two weeks ago.
The method has the disadvantagk that it is labour intensive where there
is fine foliage to be removed. I have not tried the method without removing
the foliage but feel that the foliage would obstruct the new shoot.
Without removing the tape, it is difficult to know when the graft has taken,
but the vigorous new shoots produced give some indication. I have found
Brachychitons generally to be tKe most successful and quickest to take,
usually within two weeks. However, the quickest of all so far is eight
days for Grevillea bipinnatifida onto G. 'Sandra Gordon' only just observed
in the last few days. Other grafts may take up to eight weeks or more.
Most of the trials so far have largely been limited by the availability
of suitable rootstocks and, to a lesser degree, the scion material.
I have sustained many losses in the past, using either method, when placing
the rootstock under stress, either because of erratic watering or by trying
to push them along with too much fertiliser. It only requires underwatering
on one occasion during the establishment period for the graft to collapse.
The rootstock may survive but the scion will die.
I did try to go one step further in the process by using an aerosol plastic
skin on the scion instead of the tape. Unfortunately, the chemicals in
the mixture burnt the scion and it promptly died. If there was an aerosol
plastic skin available which did not burn then it would be worth trying.
Please note that normal grafting tape is too thick and I doubt that it
would be successful for this method.
I have not tried my method on cutting grafts but I feel that there is some
potential in that field.
All normal precautions-and selection of material should be exercised.
Normal grafting tools may be used. In my case I use a scalpel with a number
eleven blade. I normally prefer a whip graft, although on occasions I
use a wedge graft.
I cut strips of Nescofilm lOcm long by 10-15mm wide and roll these onto
one end of a nail (about 65mm long). I use this to wind the tape onto
the graft and scion. I find this much easier to manipulate than a loose
strip of tape.%I keep two on hand in case one runs out half way through
the operation. The most difficult part of the process is starting the
t a p e and h o l d i n g t h e ~ i e c e s t o g e t h e r , p a r t i c u l a r l y when u s i n g a whip g r a f t .
