Sweet Pea Culture. 
The development of the modern Sweet Pea has been 
phenomenal in recent years. Size, range of color and the 
formation of the flowers have been immensely improved and 
methods of culture have changed for the better so that the 
practice of taking a packet of seed and sowing it thickly in the 
early spring, followed by placing brush in far greater quantity 
than the plants require, is far too antiquated to secure the best 
results. Plenty of room for development together with all the 
light and air possible, is essential. 
Soil The Sweet Pea is a deep-rooting plant, and soil conditions 
must be conducive to encourage this. Trench to a depth of at 
least eighteen inches and if possible three feet, work in plenty 
of manure and a sufficient quantity of bone-meal and add enough 
lime to correct any acid condition. This work is done better in 
the fall for two reasons — it allows the soil to settle before spring, 
and it gives the fertilizer time to permeate thoroughly before 
the planting season arrives.
