18 SECOND THOUSAND QUESTIONS IN AGRICULTURE 



Do not go in for summer cover crops unless you are sure you have 

 an excess of soil moisture. Irrigate and cultivate well and give the 

 trees all the advantage you can. 



Planting-Out Rooted Olives. 



/ have about 30,000 olive tip cuttings, all rooted. Would you advise 

 me to plant them in the nursery now? I figure they have a month or 

 more to establish themselves in the ground before frost. 



The planting can be successfully done in the autumn providing the 

 ground is moist enough to protect the little plants from drying up 

 before the rains come. Such planting is safer in places where frosts 

 are absent or very light but there would be much less risk in planting 

 out in February or later when the ground becomes warm and perma- 

 nently moist. 



Do Not Plant Olive Trees in Mud. 



Intending to transplant 2-year-old olive trees, I dug holes and 

 found that water filled them up in about 15 minutes. Shall I bale out 

 the water and plant with plenty of earth tamped in around the tree, 

 or had I better find out in summer time how far back from the adjacent 

 ditch the moisture will soak through the ground, which consists of 

 sand, loam and gravel? 



You should not transplant olives until everything begins to warm 

 up and the buds look like starting a new growth. This may be in 

 April or even in May. By that time you can see if there is still too 

 much water, etc. A short stand of water in such soil will not hurt 

 an olive, but if there is always as much water there, it is no place 

 for an olive or any other fruit tree. 



What Is Citron? 



Where can I get seeds of the plant producing the candied citron 

 which they sell in stores? Is it a fruit tree or a vine? 



The true citron of commerce grows upon an evergreen fruit tree 

 just as an orange does, and budded trees can be had from the nurs- 

 eries. There is a member of the melon family called the pie melon, 

 which is also called "citron" in parts of the world where citrus fruits 

 cannot grow, because the rind of it is preserved so that it has some 

 distant resemblance to the true candied rind of the citron fruit. It 

 has no commercial importance. (Curing of true citron is described in 

 Part I, Vol. 1 of this issue.) 



Causes of Coarse Oranges. 



Why are oranges rough, ivith thick rind at the upper or stem end? 

 Is there any danger of applying too much manure to orange and 

 lemon trees?
