Every year my children ask me to grow sweet corn as they love to eat the cobs straight from the garden, freshly picked, perfect in their raw state. They also ask me to take photos of them EATING their cobs as well because they think it's an amazing treat. And they're right♥
Eating corn immediately at the time of picking is the most ideal time because as the minutes tick over the starches in the corn actually increase and loses their vitamin value. That is one very good reason why the corn cobs we buy at the fruit and veg store really do not have very much taste and have a pasty texture. When it comes to eating corn, freshly picked is always the best by far.
Our crop of sweet corn is growing rapidly this year. They are so easy to grow but they need a little attention to make sure that the corn cobs grow large and juicy. Here are a few of my top tips for amazing corn.
Top 10 Tips . . .
- Choose an open sunny position for planting, but is protected from wind. If wind does become a problem, stake them and use a ties to keep them upright.
- Corn requires a moderately heavy feeding, so build the soil up with lots of good organic matter and manure before planting. I also toss a handful of blood and bone and rake through.
- Corn requires moderate watering. Never let the soil dry out completely but needs to be in well drained soil. The trick to getting those cobs really juicy is all down to your success with the soil moisture level. Many gardeners choose to water using drip-line irrigation to ensure the moisture level is adequate. This is absolutely number one in getting great corn as they are shallow rooted!
- Plant your crop in a location that has previously grown high nitrogen plants such as beans, peas, cauliflower, cabbage or broccoli. Where ever you would plant cucumbers, melons or pumpkins is the same type of soil that corn would love.
- Give your corn crop an application of seaweed solution every couple of weeks.
- Pinch off the side stalks near the base to channel more growing energy into the main stalk. The side stalks may grow back after a time, but removing these side stalks will make a big difference to your crop's yield.
- Make use of the tall corn stalk by co-planting bean seeds around the base of each corn stalk once corn is more than 5 inches tall. By the time you have harvested your corn cobs, the beans will be well on their way to using the height of the stalk to climb and produce their crop next.
- Pollination is done by wind, so mild conditions are ideal. For this reason, multiple planting is needed to ensure a good cross pollination.
- If your crop fails to produce good ears of corn, it may be due to extreme weather conditions: too hot, too cold, too wet can all affect pollination.
- Harvest only when the silks turn brown. To be doubly sure, you may also pierce the top kernels which will exude a milky or clear liquid which will indicate that they are ready for harvesting.
There are 3 main types of corn:
Standard (su types): Heirloom varieties, typical old fashion style. They need to be eaten at the time of harvest as they quickly become starchy.
Sugary-enhanced (se types): They have better keeping qualities as their sugar remains more stable after harvesting.
Supersweet (sh2 types): Very common variety that has a much higher sugar level than the others, and will remain sweet for up to 10 days after harvest.
Spring to early Summer is ideal as they require a soil temperature 16-24 C for optimum growth. Typically corn will produce only 3 ears/cobs of corn per plant.
Pinching Out Side Stalks
As I mentioned earlier, pinching off the side stalks near the base will channel more growing energy into the main stalk. The side stalks may grow back after a time, but removing these side stalks will make a big difference to your crop's yield. Don't be scared to pull. They snap off so easily. You will son see a marked difference in the size of the corn stalks if you choose to only pinch off from only a couple and leave the rest.
