144 PEACH CULTUEE. 



unless they know that they have been propagated from 

 good seed ; and also that the finds have been taken from 

 thrifty, healthy trees. This is preventive, and is better 

 than cure. 



2. Do NOT PLANT IN FOUL GROUND. We do not mean 

 by this, rough ground. Peaches may, and will do well 

 in any soil, no matter how rough it may be, provided it 

 contains the essential elements of tree food. But ground 

 is foul in the sense in which we use the term when it 

 is poisoned by unhealthy matter, such as injurious or de- 

 structive mineral or vegetable substances, or undue pro- 

 portions of ingredients, innocent enough when properly 

 combined. Hence, exhausted lands should not be planted 

 until they have been restored by proper tillage or fertili- 

 zation. And especially should not old peach orchards be 

 replanted until they have been cultivated for a period of 

 years in other crops. Clover and lime are excellent 

 restoratives. 



Under the head of foul land may be included wet, 

 springy, or miry land, which is altogether unsuited to the 

 peach, but very conducive to disease. 



3. PULL UP THE DISEASED TREES. When the Yellows 

 has once been allowed to make much headway, the best 

 remedy yet discovered is to pull up the trees by the roots, 

 and haul them out of the orchard. And this should be 

 done before flowering, as it is supposed by some the dis- 

 ease is spread by the carrying of the pollen from one tree 

 to another while in blossom. 



4. LIME AND MANURE. If the symptoms are mild in 

 character, and limited in extent, and the planter cannot 

 consent to lose his trees entirely, let him lime and manure 

 them vigorously. Stir the ground thoroughly around the 

 trees, and plow the entire orchard, and keep it in a mel- 

 low state. Then if the trees are full grown, apply from 

 half a bushel to a bushel of lime to a tree. This should 

 be sown uniformly over tho surface as far as the roots 

 extend, and not piled around the neck of the tree. If
