stump carrots grown in pop bottles

Above is a photo of the stump carrots that i grew in pop bottles this year. The type was sweet candle. As you will see they were not grown in sand but a very good make of compost which i have found to be excellent for many years. Like all gardeners they have there own litttle secrets on the way they use there growing mixtures but as i just mentioned they were not grown in any sort of sand which is used in drums ware drill holes are to be made for the growing mixture. I must admit i was not in a position during there growing period to give the attention re to watering and also checking for carrot fly which i have been very lucky by not having that problem. As to the water i did use water gel which i mixed with the growing mixture i use.
