Growing Instructions - Laelias
The two main localities for laelia species are northern-central America and southeastern Brazil. The laelias of Mexico are primarily from areas of higher elevation, 3000-9000 feet (except for L. rubescens). This gives them generally broad temperature tolerance from freezing or below, to the warmest of growing extremes. Brazilian laelias from the southeast are inhabitants of the Brazilian plateau and the sub-tropical southern coast. Hot, humid summers are characteristic of nearly all habitats, while winter freezes sometimes occur in some areas, thus giving much temperature tolerance to this group.
This plant likes bright filtered light and/or direct morning light. Avoid prolonged periods of direct afternoon light, or complete all day shade.
Temperature
Day temperatures in the 70's and 80's (F) are perfect, but even higher
temperatures up to and over 100ºF are not harmful. Night temperatures
55-60ºF are fine, though only a few require it. Most are able to
drop down to freezing and a number of them can tolerate cold to the mid
to low 20's for a few hours.
Water
Watering, as with all orchids, is done as needed. Under our conditions
watering once a week with occasional wetting down during warm times is
sufficient. Mounted plants are wet down daily on sunny summer days,
reducing down to weekly waterings during the winter. The time of
growth corresponds to the dry season from where the plants come.
Some laelias such as L. speciosa and many of the rupiculous species of
Brazil, benefit from dryness during the dormant time.
Fertilizer
Regular feeding promotes good growth. Use a balanced fertilizer
(10-10-10) or one a little higher in nitrogen (10-5-5). Micronutrients
are always desirable with the inert orchid mixes.
