The picture below shows Neville Burt holding a 23kg Hubbard Squash, which was harvested at the end of March 2012.
The seed catalogue from which the seed was purchased said ‘grows to around 6kg’.
No special attention was given to the plant other than a good dressing of EarthZing. and plenty of water.
2 plants were grown and of the 3 squash harvested, these weighed 16, 21 and 23kg respectively. Will make a good exhibit at next months Timaru Horticultural Show.
