Sponsors

Most of our 2009 sponsors have agreed to sponsor us again in 2010. Their generous support is very much appreciated. It allows us to provide a range of services for our members, such as a newsletter, guest speakers, prizes, etc and still keep our annual subscriptions low.

What we ask is that you support our sponsors where this is appropriate.

April Meeting

Please note that our April meeting will be on 22nd April. This is because the Botanic Gardens Hall was not available on 1st April because of another booking for Easter and the school holidays. Please mark this in your calendar.

Growing Competition

Our guest speaker for the meeting on 6th May will be Murray Shergold from Easy Orchids. He will be speaking on the Oncidiinae Alliance e.g. Beallara, Miltassia, Odontocidium, Degarmoana, Colmanara, etc.

And he will be judging the growing competition for the plants that he gave us after his deflasking demonstration last year. How is your plant going? Please bring it along, even if it doesn’t seem to have done much. Murray will talk about the plants and give some suggestions. The plant was Miltassia Charles M Finch.

Autumn Show

Preparations are well underway for our Show at the Botanic Gardens at the end of April. How are your plants going? Even if you don’t have any plants that you think will win a prize please bring them along so that we have a good display of plants for the public.

Please note that plants for the display need to be brought to the gardens between 6 p.m. and 7.30 p.m. on Thursday 29th April, or between 7.30 a.m. and 8.30 a.m. on Friday 30th April. There is a copy of the show schedule on our website. The secretary has a few spare copies.

Ivy is looking for people to help out with the various jobs which make the show a success. Anyone with items for our raffle should see Bruce Hall. Please note we are after QUALITY plants.

Preparing plants for a show

At our March meeting Steve Clemesha spoke about preparing plants for a show. Using orchids from the members on the night, Steve covered topics on cleaning up the orchid plants in removing all dead and decaying matter from the plant. A number of aspects on staking plants for presentation were also given. Suggested that staking should occur while plant is still in bud, normally stake to lowest branch if a branched spray and don’t have stake above highest flower.

Consideration was given to the flowers, any marks, and the number of open buds per spray, damaged flowers and the like.

The treatment of diseased plants, along with the treatment of pests was also talked about. Carefully check plants for disease – please don’t bring diseased plants to show. Scale and mealy bug can be removed with white oil. Leaves can be cleaned with white oil or milk.

Steve’s talk generated a number of questions in relation to labeling, whether the plant is a species or hybrid. Duties of the show marshal.

Growing Softcane Dendrobiums

Part Three. Following from March Coffs Orchid News, this is taken from a chapter by Sandy Anderson – one of our life members in the booklet “Orchid Culture by leading North Coast Growers”

POTTING

Size of pots, type of potting material and water frequency are all inter related. In brief, the smaller the pot and the more open the mix, the more often watering will be needed. However, don’t use larger pots or finer mixes than necessary. We grow our single flowering cane plants in 100mm (4”) pots and a mix of 2/3 Casuarina bark ( ¼” to ½” grade and1/3rd perlite and water well in the late afternoon daily during summer. On hot days (over 30 degrees C) we give a 4 to 5 minute watering once or twice during the day, mainly to increase the humidity.

Repotting is done as soon after flowing as possible and before the roots on the new leads can be damaged. If any organic material is used in the mix such as bark etc. 2 years will be about its limit.

When dividing or trimming old growths at re potting time we leave 3 years growth on the plants. These old canes act as a reservoir for food for new growth.

PEST AND DISEASES

These orchids are subject to attack by pests that growers know only too well and are treated with insecticides appropriate to the pest. The exception to that is leaf spotting. This is caused by a fungus and we control it completely with a fungicide spraying every week. We are still using Captan, but when our supply runs out we will try Dithane 45 which was recommended to us by the Agricultural Department

FLOWERING

Soft canes Dens need a cooling off to initiate flower buds. Yamamoto says a month of nights at about 10 deg is needed, but we believe 13 deg is cool enough. If plants are placed in a good position where good light reaches the full length of the flowering cane at bud initiation time, you will find that they develop over a greater length. If crowded together at that time flowering will be confined to only the top sections.

SOME HELPFUL HINTS

A porous floor covering that can be kept wet. Sawdust or wood chips are good or some sort of plant growing on the floor will improve humidity. The closer your soft canes are grown to the floor the better. Hanging plants to the roof provides the lowest humidity.

Polystyrene boxes turned upside down, with holes cut in them to the pot size with a sharp knife are good to hold plants upright and trap moisture in the root area -a definite plus.

It will also help if plants are grown fairly close together for the hot growing season but space wider in autumn for better flowering.

Flowers are long lasting but this can be extended by keeping the plants cool and the flowers dry when watering.

TO SUM UP

  1. Fertilize and water freely all summer.
  2. Stop fertilizing not later than mid March
  3. Water all year if conditions are dry.
  4. Grow under plenty of light and air movement
  5. Sit back and enjoy the results
