We grew corn in a group but the cobs only partially fruited. What do you think went wrong?
There are few things that may have impacted your corn resulting in the partially developed cobs; soil, fertiliser, mulch, and watering. You have done the correct thing by planting your corn in a group which aids pollination, and it also helps the plants to support themselves as they grow. Many people think corn can be grown anywhere, but it does need a nice rich, friable (crumbly) soil so it’s worth preparing it well before planting. Add in lots of compost and garden mix, and combine well with existing soil.
Corn is actually a gross feeder and needs regular application of fertiliser throughout the season. As the plants start growing you should regularly side dress with Daltons Vegetable Fertiliser – make sure you water it in well. As the plants continue to develop, water them deeply up to twice a week until the cobs mature. Regularly apply mulch as this aids water retention by hindering water evaporation, keeping the moisture in the soil.
