Rhubarb (Rheunz rhaponticum) aperennial plant, does not comeinto the normal garden crop rota-tion, and a special bed should beprepared where it can remain forsome years. As with all perennial
crops, success in growing rhubarbdepends largely on the initial pre-paration and building up of thesoil before planting.
A large quantity of organicmanure should be worked into thelower layers of the soil, out of therange of the roots of newly plantedsets. No stems should, be pulledfor the first year after planting,and pickings should be light duringthe second year.
Good drainage and heavyannual manurial dressings willkeep the plants producing, butafter the fifth year from plantingthe crowns should be lifted,divided and replanted, using onlythe younger outside buds.
Most varieties do not producestems all the year round, and a
range of sets from the mainvarieties Stone's Ever-bearing,Sydney Crimson, Wilson's Ruby,Wandin Giant and Topp's Wintershould therefore be planted. Thesewill give a succession of harvestdates covering almost the fullyear. Five plants will provide areasonable supply for the averagefamily.
Rhubarb can be grown fromseed, but seedlings are not always
true to type. Where it is difficultto get sets, seed can be sownduring the winter and transplantedin the spring.
The plants will grow enoughstem to allow their quality to beassessed. Those selected can begrown on for another seasonbefore being set out in the per-manent beds. Where obtainable,sets are the most satisfactorymethod of propagating rhubarb in
the home garden.
Soil preparation and fertilisers
The rhubarb bed must be welldrained. The bed should betrenched before planting, even if the ground has been trenchedbefore. When trenching the sub-soil, as much organic manure ascan be spared should be dug intothe subsoil and the lower topsoil.A 150 to 200mm layer would notbe too much. A liberal dressingof NPK 5 : 8 : 4 completefertiliser should be worked into thetop soil.
Planting setsThe sets are taken from estab-lished clumps. Each should haveone or two buds. Obtain setsfrom a reliable source so that theright seasonal varieties will be
planted. As old crowns develop
decay and rots, it is advisable todip sets taken from them in a fun-gicide spraying solution, such asBordeaux or other copper fun-gicide before planting.
Plant the sets at a depth whichwill bring their buds just abovesoil level after allowing for settle-ment of the surrounding soil.
Space the plants800
mm apartand make the rows one metreapart.
CultivationRhubarb requires heavy feeding
during the winter. Apply 150 g
of NPK 6 : 6 : 6 completefertiliser to the metre around theplants, and fork it into the soil.This can be supplemented duringthe growing season by application
of liquid manure.Rhubarb should be wateredliberally in summer. A mulchhelps to retain moisture. Break off any flower buds as soon as theyappear. Flower development ex-hausts the crown.
HarvestingThe stems, which may be pickedat any stage, should be taken witha downward pull so that they
come away from the crown with-out leaving a stub. Pick the out-side stems first, always leavingsome of the centre stems to pro-tect later shoots.
Several stems should be allowed
to mature on the plant. Seasonalpicking ceases when the later stemsdeteriorate in size. The plantsshould never be completelystripped of stems. Some must beallowed to remain to mature and
ripen off naturally.

Salsify andScorzoneraSalsify (Tragopogon porrifolius)it is very like parsnip and is cul-tivated in much the same way.Salsify makes a soup which has anoyster-like flavor, or can be cookedin the same way as parsnip. The
roots store well in the ground forup to six months.
Soil preparation and cultivationSalsify is deep rooted and may beup to 50 mm in diameter at thetop. Soil should be well prepared.Dig the bed deeply and dig in com-post or animal manure. Salsifywill do well without additional fer-tiliser in soil which has previouslygrown a leaf crop and has been
well manured.Sow seed in the spring or
summer in shallow drills. Coverseeds with 10 mm of soil and thinto 100 mm when the seedlings are50 mm high.
Salsify is ready for use in fiveto six months. Roots should belifted carefully with a fork, notpulled. A good quality root shouldbe as symmetrical and tapered asa small parsnip.
Scorzonera (Scorzonera his-
panica) is a close relative to thesalsify and is grown in exactly thesame way. I t is used and cookedlike parsnip. *zonera and Salsify.
Cooking SaZisfy and ScononeraThe roots should be gently scrapedbefore cooking to remove only athin layer of outer peel. This canalso be done by first boiling the
root to soften the skin. Beforecooking, soak the peeled root inwater containing lemon juice.Salsify can be boiled, mashed,baked or fried, as well as beingused for soups.
Silver beetSilver Beet (Beta vulgaris) igrown easily and provides a6
ditional greens during the winterIt is a true beet but forms leaverather than bulbs. In New SoutWales it is known as spinach.
Cultural requirements are thsame as for beetroot. Seed ca
be sown from January througMarch, and again in August andSeptember in the south and in thsummer and early autumn in thnorth of Victoria.
Soil requirements and fertilisersLike beetroot, silver beet does nolike an acid soil and liming mabe necessary. It should be growwithout a check. Apply a goobase dressing of fowl manure an
75 to 150 g of NPK 5 : 8 :complete fertiliser. Side-dressingof sulphate of ammonia, 30 g t
each metre of drill row, will maintain good growth.
Sowing and cultivationSow seed in drills 500 mm aparand 20 mm deep. When seedlings are 50 mm high thin to 30
mm apart. Thinnings can btransplanted in another row
Leaves are pulled off like rhubarleaves and the leaf stalk and thleaf cooked either together oseparately. Discard older outeleaves if picking is not regular.
