MEMBERS’ SUMMER CHALLENGE
Each member of the Ropley Horticultural Society is provided with a plug plant in March to grow on and exhibit in the Summer Show.
The Summer Challenge Cup is awarded to the best exhibit.
The plant for the 2021 Summer Challenge is: Pelargonium “Klass” (deep pink)
The plug plant supplied free to members at the end of March should produce a quality flowering plant by the time of the show on 21 August 2021.
Plant the plug into a 9cm pot as soon as possible using a quality potting compost, with a little perlite or vermiculite added (in a ratio of 4 parts compost to 1 part additive). Keep the plant in a warm light place.
Repot again, in stages (minimum of two times suggested), up to the maximum pot size of 23cm internal diameter.
In order to produce a bushy plant with plenty of flowers at the time of the show, it is necessary to ‘stop’ the plant:-
- Soon after potting up the plug plant, pinch out the tip of the growing point ie stop the plant, to develop a framework of stems.
- 14 weeks before the show - around mid May - stop each stem, as above
- 9 weeks before the show - around mid June - disbud by removing all buds above the level of the foliage. To develop even growth, turn the pot regularly. (Suggest a quarter turn twice weekly).
Compost retains its nutrients for approximately six weeks. There are 24 weeks between receiving the plug plant and the show, therefore it is beneficial to feed the plant at each watering. Use a liquid tomato feed, or equivalent, diluted as directed.
Do NOT over water. Only water when the plant is nearly dry and preferably water from below.
