Among the numerous varieties on the market, after much deliberation, you will definitely find the right specimen. In order for the cultivation of your chosen sweet corn to be successful, there are a few things to consider.
Sweet corn can be grown indoors from the end of March
Where and in what does sweetcorn grow best?
An ideal location is found in a sunny, warm and wind-protected location. The substrate in which the sweetcorn is planted should be thoroughly loosened before planting, enriched with lime and an organic fertilizer such as compost or manure. The following features are important:
- pH between 5.5 and 7 (slightly acidic to neutral)
- high nutrient content
- profound
- calcareous
- to keep well moist
When are the seeds sown?
The seeds can be grown in pots at home from the end of March/beginning of April to the beginning of May at the latest. Before sowing, it is advisable to let them soak in water for a few hours. Direct sowing does not take place before mid-May, since sweet corn is sensitive to cold.
Which plant neighbors are suitable?
The sweet corn can be cultivated with shallow-rooted vegetables without any problems. A mixed culture with runner beans and pumpkins is also known. Good plant neighbors include:
- peas
- beans
- cucumbers
- pumpkins
- melons
- zucchinis
- salads
- potatoes
- sunflowers
- dill
What distance between the rows and the plants is necessary?
Planting in blocks or double rows is recommended so that the individual plants do not hinder each other and can still pollinate well. A row spacing of 60 to 80 cm is ideal for walking through and looking at later. A distance of between 30 and 40 cm from plant to plant in the rows is sufficient.
When is the sweet corn harvested?
The sweet corn is ready to harvest about three weeks after the flowering period. Basically, the ripeness of the cobs depends on the variety. But the intended use (seed collection or consumption) is also decisive. Some varieties ripen at the end of July, while other varieties are not ready for eating until mid-August.
tips
Sweetcorn is easily propagated by leaving a cob on the plant and waiting for it to fully mature and begin to dry. However, this can only be achieved with seed-resistant varieties such as 'Damaun' and 'Golden Bantam'.
