POSTULATES OF TULIP-BULB PRODUCTION. 



(1) Do not plant on lean soil. 



(2) Use the most available source of fertility and utilize it to the 



utmost by a thick and exhaustive planting. 



(3) Continually strive to plant back every year as large a percentage 



of the smallest bulbs that will grow to maturity in one year 

 as is compatible with maintenance of stock. 



(4) Do not sell all the large bulbs, but plant back a small number 



of the largest and best, especially of the varieties which repro- 

 duce poorly. 



(5) Do not plant on the same ground more often than once in two and 



preferably once in three years. 



(6) Dig and replant every year. 



(7) Practice clean culture; keep down weeds. 



(8) Preserve the bulb coats; do not let the bulbs mold; handle them 



without bruising. 



(9) Avoid having the broken tulips in close proximity to the breeders 



or self-colored stocks. 



(10) Plant early. The best results are to be expected from plantings 



made before the end of September.
