Growing Large Exhibition Onions in The Greenhouse – update 23/06/2011

Onions continue to do ok with the exception of one thats got Saddlback whereby they growing point gets stuck and grows out of the bottom of the bulb! it completely ruins that bulb.

The best bulb at the moment is about 24.5 inches in circumference, that says they have grown about 10.5 inches in 5 weeks, I would have expected more but June has not been very warm on the North East Coast. There is still nearly 3 months growing time before the big show but growth of onions slows down from now on , I am just hoping they dont stop growing as they sometimes do.

I have applied Red Spider Mite predators Phytoseiulus persimilis as we move into Red Spider Mite season.

The onions get watered every 2 days with about 3 litres per pot around the edges taking care not to get water on the leafs or the bulb. I do not feed them at all with any liquid feed, there should be ample in the soil.
