Multiple spikes on dendro question?
 

Specifically on phal types, how do you get multiple spikes? Do they respike from older already flowered pseudobulbs?

Basically just good care. If they are large healthy plants they can have multiple new canes growing in a season which can then flower together.

However yes... two of mine are currently spiking of old canes and one of them has just finished on flowering on the new cane. It was very close to having two at once.

thank you
