Gardening Under Glass 



Plants growing in a lean-to are bound to "draw" 

 or lean strongly in one direction because of the 

 uneven distribution of light, and the difficulty of 

 proper ventilation. .;. 



POSSIBILITIES OF THE UNHEATED GREENHOUSE - 



Prickly Spinach sown in August will germinate and carry through the winter. 



Half-grown Lettuce from the garden will mature if brought in. 



Cauliflowers not yet headed will mature inside. 



Dandelions may be grown for winter greens from strong roots that have first been frosted 



outside. 

 By January 15 sow Peas, Radishes, Lettuce, and Round Spinach. 

 In February sow Lettuce, Beets and Spinach. 



Plant Asparagus roots under benches, cover with 3" of earth, and cut in March. 

 Mushrooms may be grown also, as the natural warmth of late winter's sun suffices. 

 By January 25 sow Sweet-peas, Bachelor Buttons, Mignonette, and Marigolds. 

 February 25 start any deciduous shrubs desired, also Tulips, Hyacinths, etc. 

 Bring indoors any sprmg-fiowering herbaceous plants for early bloom.
