would like to grow wisteria up a balcony that has only concrete
beneath it and not a lot of room for large pots. Would a wisteria
survive for a number of years in a smaller sized pot. If so, what
would be the main criteria to ensure it remained healthy and flowered
profusely? Do you recommend any particular white wisteria that would
be particularly fragrant?
wisteria grows well in pots and is used in the ancient art of bonsai.
The pot size you select will depend upon how big your plant is now.
I would not go any smaller than 35 cm for a metre high plant. Choose
the maximum size pot that will fit the space. The bigger the pot,
the bigger your wisteria will grow.
Your wisteria could remain
in that pot for several years. Additional fertiliser would need
to be added use Osmocote granules at three monthly intervals
during spring and summer. Liquid feed throughout spring and summer
Thrive Flower and Fruit will also benefit your wisteria.
Keep well watered throughout the growing season; water every day
during dry periods.
There are products suited
to growing plants in containers that will assist your wisteria
a wetting agent such as Saturaid will help channel the water to
the plant's roots where it is needed. Crystal Rain water crystals
will help retain moisture in the potting mix. Seal your terracotta
pot with Terraseal pot sealer or silicon spray to help prevent drying
