This is my sixth and final article on the different sowing dates used by 6 top exhibitors from different regions of the Country. So far the response that I have had to the articles has been very positive and encouraging for me and to the growers who helped me put it all together.

This is my sixth and final article on the different sowing dates used by 6 top exhibitors from different regions of the Country. So far the response that I have had to the articles has been very positive and encouraging for me and to the growers who helped me put it all together. One word of caution however; after many years of growing vegetables under all sorts of weather conditions, sowing dates is certainly not an exact science as it is so dependent on seasonal factors.

The dates given in each article by my colleagues are the dates that they use and I know for a fact that they would be the first to admit that sometimes even they get it wrong. One of the two worst vegetables for timing are Cauliflowers and Celery, they are a single specimen vegetable and therefore if they are not ready for a given date or were ready a few weeks prior to that date, then there isn’t a lot you can do about it. Multiple cropping vegetables such as peas beans and tomatoes are a lot easier as you can still get specimens higher up the plant a few weeks later than you had timed for.

Another question that I have been asked since these articles were published is what date to use if they do not live near to any of the growers dates. Well you may find it useful for instance if you live somewhere between Bob Herbert from Derby and John Branham from Aylesbury to split the sowing dates; For instance Bob puts in his first sowing of Gringo short carrots on the 8th April whilst John would sow them on the 20th April. If you therefore live somewhere between these two areas then why not sow your first batch on the 14th which is half way between the 8th and the 20th, you wouldn’t be that far away come show day.

My last sowing dates were given by Charles Maisey from South Wales who is well known throughout the country for some exceptionally fine specimens of vegetables. Over many years Charles has performed at the highest level and has excelled with Runner Beans, Tomatoes, Cucumbers, Potatoes and Peas. Charles is quite a scholar at the exhibiting game, if you notice he never grows onions or leeks or shallots because he realised many years ago that he couldn’t grow them to the standard that he would like so he dropped them. Instead he concentrated on those vegetables listed above that he did grow particularly well.

There is certainly a lesson here for many up and coming exhibitors who want to make their name at the highest level, concentrate on the vegetables you know you can grow well and make your name with them. To assist Charles with sowing dates for those items that he no longer grows he asked Jim Thompson to assist him, Jim is a National exhibitor who lives only a few miles away from him.

Charles is a National Judge and Chairman of the Glamorgan District Association of the National Vegetable Society and his vegetable plot is certainly a joy to see. Charles practices what I have repeatedly said, a mixed vegetable garden at it’s peak is a work of art and more beautiful than any floral garden.

Here are Charles’ varieties and their sowing dates for those on the list that he grows:-

I trust that the six articles have been of use to all of you who might consider exhibiting at either the Welsh Championships on the 26th of August and/or the National Vegetable Society Championships which are held at Malvern on the 29th September.

My whole hearted thanks must go to the six contributors as without their willing assistance the job could never have been completed; Also my thanks once more to Harry Atkinson who first planted the idea in my mind.
