My pleurothallids are happiest here in my area during late Fall to early Spring when we get cooler temps, tule fog, occasional cool rains..that is when I get some blooms. It is really great they thrive better here during our very mild winters. But mine are Barbosellas, not masdies. Come summer..I just try to find the shadiest spot I can and frequently water them to cool down. Thankfully this May is cooler than usual..fun for the 'chids.
