In Production Today, September 2014

Spring is over in my garden. Winter crops are flowering – my garden is transitioning into its seed saving phase.

I’ve replaced several unsatisfactory fruit trees and used the opportunity to increase diversity (another blog, another time).

The mulberries are flowering, the ‘White Shahtoot’ mulberry (Morus alba var. laevigata, syn. M. macroura) for the first time. Also, my 13 year old Pouteria australis (syn Planchonella australis), a Native plum aka Black Apple, has its first flower buds. I sowed this tree in 2001, so I’m keen to see if I finally get fruit.

Last month, I filmed a story for Gardening Australia about brassica pests with my friend, Gurion Ang, a PhD Entomology student at the University of Queensland. Gurion confirmed that my garden has a healthy population of White Butterfly parasitoid wasp (Cotesia glomerata, Species Number 434 found at Bellis). This biocontrol manages Cabbage White butterfly (Pieris rapae) but the parasitoid pupae are often mistaken by amateur gardeners for pest eggs. Instead of keeping them, they are often destroyed.

I’m particularly pleased to have a small planting of Landcress, Barbarea vulgaris sourced from Greenpatch Nursery (Taree, NSW). This plant has a family connection, because my maternal grandmother started growing this during an unprecedented drought in England in 1975.

Instead of requiring lots of water, like Watercress, Landcress needs much less water to produce its peppery tasting leaves. Nan also noticed her cabbages did better than normal that year and grew Landcress from then onwards, believing it to be a good companion plant. Gurion confirmed my grandmother’s opinion.

Cabbage White butterflies find Landcress irresistible, they always lay eggs on this plant in preference to other brassicas. Caterpillars feed on the leaves and are unable to detect that Landcress contains saponins, soap-like compounds which kill them. Saponins give humans a stomach ache, so it’s important to lightly boil or steam leaves to neutralise them before eating: using them for coleslaw is not recommended.

Huauzontle, Chenopodium berlandieri, also contains saponins and it too harms Cabbage White butterfly caterpillars. They start nibbling it but fail to make it to pupation. I’m going to use Landcress as a regular Trap Crop in addition to huauzontle.

Gurion also confirmed that my Ethiopian cabbage, Brassica carinata ‘Old Women Meet & Gossip’ and my ornamental kale, Brassica oleracea ‘Coral Seas Mixed’ have a waxy coating on their leaves, unlike Asian or European brassicas. Cabbage White butterfly love Asian and European brassicas, which lack the waxy leaf coat, but the African brassicas and ornamental cabbage and kale do not greatly appeal to Cabbage White butterfly, and their caterpillars never prosper on them.

An alternative use for Asian and European brassicas, is growing them as a sacrificial crop. Growing some of them alongside a favourite brassica they attract pests so your favourite crop grows unharmed. Just remember to eliminate the sacrificial crop before the pests pupate and start reproducing!

Edible Chrysanthemum, aka Shungiku, has had a name change to Glebionis coronarium (syn. Chrysanthemum coronarium). I’ll have to update my photo library.

    Hi Jerry. I came across the following excerpt on Mangel Wurzel from an early newspaper while researching another topic for work and thought you might be interested:

    Colonial Times (Hobart, Tas. : 1828 – 1857) Friday 27 November 1829 p 3b (accessed via Trove, 24/9/2014)
    Mangel Wurzel.
    This root was first introduced into this country, for general use, about the year 1786 by Thos. Boothny Parkins, Esq. then residing, at Metz, in France, who sent a packet of the seed to the late Sir Richard Jebb, Bart. The roots at Trente Place, the product of the seeds sown by Sir R. J. weighed about ten pounds each. Amongst the greatest promoters and earliest cultivators of this root, we find the late Sir W. Jermingham, and Sir Mordaunt Martin, of Norfolk In the year 1815, the latter sowed Mangel Wurzel and Swedish turnips in drills alternately; the result was, that every mangel wurzel was bitten by the hares and rabbits, and not a Swedish turnip was touched. Sir Mordaunt subsequently covered up a wheelbarrow full of mangel wurzel with a cart load of Swedish turnips, and his cows turned over the latter to get at the former, as horses do cut straw to get at oats; swine, too, he says, will leave a corn, stack to get at them, and will fatten thereon sufficiently for roasting pork. Dr. ?ettsom calculated, that from the produce of his garden, a square yard of ground planted with the mangel wurzel would yield fifty pounds in weight of salutary food. Mr. Harvey, of Alburgh, in Suffolk, says, he finds good mixed soil land, to be far preferable to either light, strong or wet land. In one year, upon his best land, Mr. H. had 47 tons, 15 cwt.; upon the light, about 40 tons, and upon the wet cold land, not more than 35 tons per acre. The quality Mr. Harvey describes is superior to any other root known in tins country; bullocks, sheep, or pigs will, after the first three or four days, leave every other root for it; bullocks, he says, do quite as well at mangel wurzel as at oil cake. In Hertfordshire it was first introduced amongst the tenantry of the Marquis of Salisbury, who have ever since been growers for the sole purpose of feeding and fatting of cattle. In 1813, Oliver Cromwell, Esq. of Cheshunt Park, Hertfordshire, had two roots which weighed together 61 lbs; the heaviest of the two weighed 31 lbs and measured 34 inches in length (including five inches of the stalk leaves), and 28 inches in circumference. On many farms in the Fens of Cambridgeshire and Isle of Ely, the produce has been abundant beyond example. Mr. Clayden, an extensive farmer at Littlebury, in Essex, considers the root of great advantage to the occupier of a strong clay soil, which is not adapted to the growth of potatoes, as it comes early to market and may be carted off the land any time in October, thereby enabling him to winter more stock, and to sow his land with wheat if he thinks proper. Mr. Moyse, of Denny Abby farm, a gentleman of great practical knowledge in farming and grazing, planted in the season of 1827, forty acres, and calculated the produce of roots at 50 tons weight per acre; the year previous, Mr. M. says he had 48 tons, and the crop was not so abundant as the last. Mr. Moyse never strips the leaves from the roots, thinking, that the trampling over the land, and loosening the roots, occasion more injury than the value of the leaves will compensate, but, when he takes up his crop, ploughs them for manure, as is customary with green cote seed. In sowing for a crop, Mr. M. recommends (especially on good land) to plant them in ridges 30 inches asunder, and to leave the plants 18 inches apart.

    1. Dear Lucinda,

      That is very kind and thoughtful of you. It’s a beautiful and informative piece. When I managed the Royal Botanic Gardens, Sydney (1992-2003), I delighted in having access to the library. Whenever I could, I read an Agricultural Gazette, which evolved into The Gardeners’ Chronicle, a UK publication. I think that is my most loved horticultural publication.

      Thank you so much!

      Jerry

    Jerry notice that you have Old Mans Saltbush on the list of edible leaves can we eat them thought it was only a fodder plant

    1. Think again. You don’t think I would list something as being edible if it wasn’t, do you?

  3. bruna mumbulla says:

    hi Jerry
    thank you for the lecture at griffith uni, it was really interesting n inspiring. Could you please tell me
    when is your next open day. Will you have the lime tree which gives u 4 – 6 crops a year and the rare Mandarin tree for sale. Which avocado type is ideal for small garden? How do i get coriander to last in my garden?
    THANK YOU again for giving up your time to answer my questions and lecturing at Griffith.
    bruna

    1. Hi Bruna,
      Thanks for the thanks.
      I am a busy person and if you want free advice, please ask single questions.
      Question 1. My Open Day is Mother’s Day weekend 2016.
      Question 2. You can buy Tahitian lime anywhere, try Bunnings.
      Question 3. As I said at my talk, I can only sell ‘Parramatta Sweets’ mandarin after it has recovered from cyclone damage and produces fruit.
      Question 4.Choose an avocado that has been grafted on Dwarfing Rootstock. Plant two trees, selecting an A pollinator and a B pollinator. Discuss at the place of purchase.
      Question 5. You never stop coriander from flowering – or you miss out! Collect their seed, use it as a spice, and keep on with successive sowings
      Thanks
      Jerry
