Prune it back after flowering (April/May) taking all the long traily bits, and prune again hard in late September. Starting now, give it blood, fish and bone meal as this not only promotes good leaf growth, but strengthens the roots and will help it flower better next year. Be patient- it's worth it!!
Reply:Watering: The wisteria needs lots of water during the growing season. In summer, after flowering, place the pot in a tray of water so that the plant can soak up as much water as it needs. Do not allow the water to stagnate. Water heavily before and during flowering.





Feeding: In general, wisteria need more fertilizer than most bonsai. However, in order to ensure good flowering, feeding should be minimized during and immediately following flowering. Fertilize heavily in spring before flowering and in late summer and autumn, until the leaves drop.





For organic and slow-acting fertilizers, feed double the usual strength for bonsai, applying fertilizer at the recommended intervals. For chemical fertilizer, you can either use it full strength every other week or you can use it at half strength every week.


The dry racemes should be cut off, leaving 2-3 shoots at the base of the raceme. At the same time, pinch back the tender tips of these shoots. After this pruning, many tendrils will emerge. These tendrils grow rapidly, as much as an inch each day. The tender tips of these shoots should be pinched back as soon as they have 4-5 sets of leaves. Do not remove the new shoots until the end of August, otherwise the plant may set new flower buds and bloom again that summer, which will weaken the blooms the following spring. After August, completely remove any shoots that are not going to be used as branches. The wisteria sets blooms on the short lateral shoots rather than on the tips of the growing shoots, so removing the tips will not endanger the following spring's bloom.





If you want a good bloom in the spring, remove any seed

Reply:prune it after its flowered, and then again in late winter, beware of products like miracle grow as they just produce fleshy growth that is then likely to get diseased, instead just mulch the roots with manure or compost. its probably quite healthy but just hasnt been pruned in years, if you prune it this year all the new growth will have flowers next year. happy gardening!
Reply:you can cut it back after it flower's





Try feeding it with some miracle grow in the mean time
