How to Grow Corn in Balcony Flower Pots: A Planting Guide and How to Plant Corn Seeds
Who wouldn't want a"miniature cornfield"on their balcony? Watching the tender green seedlings break through the soil, shoot up to2m tall, leaves unfurling in the wind, plump ears hidden among the husks--that sense of accomplishment from sowing to harvest is more healing than buying ten jin of corn!
But many friends always worry:"Is the balcony light enough?"
"Will thin, weak corn plants produce empty ears?"
"Fujian is so hot in August, is it still too late to plant now?"
Don't panic! This super-detailed balcony corn growing guide will walk you through avoiding every pitfall, so you can easily achieve"corn freedom"!
Step1: Seed selection and sprouting are key
At first I tried planting supermarket corn kernels and they all failed,choosing the right seeds is what really matters!
Seed selection: for sweet corn choose Jinbaitian/Xuenuo, and for fruit corn go for Jinguan218
Three-step sprouting method: soak in warm water for3hours->wrap in a damp paper towel2days until the white tips show->then sow, with a germination rate of99%!
Step2: Sowing timetable+Container guide
In the north, sow at the end of4 when soil temperature reaches12°C, and in the south you can plant two seasons in3month/8 month, so Fujian friends should hurry and get going now in8 month~
On the balcony use a40cm deep growing box, or for ground planting build a20cm high ridge with furrows to prevent waterlogging
Sowing tips:
1. Dig a3cm hole and put2 seeds per hole (to prevent birds pecking)
2. Plant spacing35cm, row spacing60cm (too dense and they compete for nutrients)
3. Cover with soil and water thoroughly, and in5-7 days tender sprouts will pop up~
Step3: Three key moves for water and fertilizer management, so corn is plump with no bald tips
Seedling stage: water once a week with1 round of rice-washing water (prevents lodging, stalks become super sturdy)
Tasseling stage: sprinkle plant ash+sheep manure fertilizer (cobs become plumper)
Grain-filling stage: mist with water morning and evening (the key to kernels bursting with juice!)
Pollination tips: when the tassels shed pollen, shake the plants every morning to help pollination and reduce bald tips~
Pest control+Complete harvesting guide
Hang yellow sticky traps for aphids, spray Bacillus thuringiensis for corn borers, and immediately remove leaves when you find armyworm egg masses
Harvesting signals: the corn silks turn dark brown, and when you pinch a kernel it oozes milky white juice; the optimal window is only3 days! Picked and boiled right away, sweetness is atMAX~
