Prof. Charles Hartman, Ph.D.Growing kiwi in containers allows gardeners to circumvent poor soil conditions and harsh winters. I have grown Issai in 25-gallon fabric pot containers for the last decade. I would use a 50-50 mix of compost to perlite, as perlite allows for good drainage while supporting deeper root systems and preventing water logging. I'd recommend drilling at least three drainage holes at a 1-inch minimum.
Pot Selection
- 25-gallon fabric pots prevent root circling
- Elevate pots 2" off ground for airflow
- Black containers absorb heat in cool zones
Root Management
- Prune roots every March before bud break
- Trim 30% of outer roots with sterile knife
- Refresh top 6" of soil annually
Pollination challenges are heightened in containers. While male vines typically pollinate eight female vines, potted plants bloom at a faster rate. Additionally, I staggered the males and females on wheeled plant stands. I hand-pollinate using a makeup brush daily to gather pollen during flowering. After working out the timing, I saw a 40% lift in my yields.
Leaf Yellowing
- Test soil pH monthly, adjust below 6.5
- Apply iron chelate every 14 days
- Check for root-bound conditions
Poor Fruiting
- Increase pot size by 5 gallons yearly
- Use bloom-boosting 3-12-12 fertilizer
- Ensure 6+ hours of direct sun
To provide some protection over winter, you may move your container-grown kiwis to a garage that does not have heat. Water them once a month, even though the roots and plant are dormant they still require some moisture. I wrap all of my pots in bubble wrap if they are below Zone 6. Using this method, it has protected Arctic Beauty varieties down to -25°F (-32°C). Avoid pruning until you see new growth in spring.
