A CALENDAR OF REMINDERS 209 



MARCH 



Increase the amount of moisture in Orchid houses by damp- 

 ing floors and stages frequently ; the atmosphere outside is usually 

 dry this month, and bright sunshine generally accompanies a low- 

 temperature and dry winds. 



Shading must be given during the brightest hours of the day, 

 as the plants cannot stand as much sunshine at the end of the 

 Winter as at the end of the Summer. 



Deciduous Dendrobiums should be potted and top-dressed as 

 soon as they pass out of flower, and encouraged to grow 

 vigorously. 



Seedling Orchids that are sufficiently large should be potted 

 off separately. 



Thunias will commence new growth towards the end of the 

 month, and potting must not be delayed. 



Odontoglossums that were not potted in the Autumn may 

 need that attention now, and it is a mistake to defer the operation 

 until warm weather arrives. 



Calanthes must be potted as soon as their new growth 

 advances. 



Let Mexican Laelias have the benefit of all light and sun- 

 shine, and only give them sufficient water to keep the pseudo-bulbs 

 and leaves plump. 



Evergreen Dendrobiums will need additional moisture to assist 

 them in the development of their flower spikes. 



Pot Miltonia Roezlii if the plants need new rooting material.
