Caring for potato vine
- Water regularly during the first 2 years after planting.
- Adding fertilizer in spring and summer will boost and extend the blooming.
Pruning potato vine
Pruning isn’t really needed but you can still balance or reduce branches overall.
Indeed, potato vine can quickly become invasive if it has settled in well, and that’s why pruning it often can help control it.
- Prune both in in spring and summer if you need to prune several times. If once a year is enough, better in spring, then.
- When pruning, watch for dead wood, broken branches or weak ones and remove them.
- Never prune in fall because this would weaken your potato vine just before winter.
Potato vine in winter and how to protect it from the cold
Potato vine is vulnerable to freezing. It can resist low temperatures, but below 23°F (-5°C) or or 21°F (-6 °C), you’ll need to winterize it against the cold or it will die.
The first years, it is crucial to protect its roots with a thick layer of dried leaves, for example at least 8?to?12?inches (20?to?30?cm).
If the leaves have frozen and died, simply cut everything off in spring and your potato vine should grow anew if the roots were well protected.
