fore they come out seem to be about as 
long* as the tree. (Laughter). 
Question 13. Which is better, a two 
year bud or one year bud orange? 
Mr. Hart: I think the larger the trunk 
is, up to four or five inches, the quicker 
you will get a good, bearing grove. They 
are stronger and put on a much more 
rapid growth. I would rather plant a 
large tree and save all that time that is 
spent in waiting for the smaller tree to 
make its growth. 
Question 14. Would spraying fun¬ 
gus spores for whitefly control be likely 
to spread lemon scab on sweet orange 
trees ? 
Mr. Hume: I would advise the in¬ 
quirer to obtain and read Experiment 
Station Bulletin, No. 103. He will find 
full information in that Bulletin. 
Question 15. Would spraying for the 
whitefly be apt to spread the whitefly 
fungus ? 
Mr. Hume: I think this question can 
safely be answered in the negative. 
Question 16. Please inquire where 
whitefly fungus can be obtained, both red 
and brown. 
Information was given that these fun¬ 
gi could be purchased from the following: 
Frank Sterling, DeLand, Florida. 
J. A. Stevens, DeLand, Florida. 
G. E. Story, Eustis, Florida. 
Question 17. How does sheep man¬ 
ure compare with fish guano ? Have been 
asked this many times and would like the 
views of others. 
Dr. Coffin stated at Winter Park he 
had obtained the most beautiful growth 
by using sheep manure. The question 
was discussed more or less generally. 
Mr. Hume finally stated that those who 
had secured excellent results by this line 
of fertilization might keep it up, but to 
look out for die back. 
Question 18. What about using 
muck ? 
Mr. Gaitskill: I can answer that brief¬ 
ly : It does not pay. 
Mr. Rolfs: I think we can repeat a 
quotation used before the Horticultural 
Society fifteen or twenty years ago, in 
connection with this same question as to 
using muck: “Applying muck to a citrus 
grove is harmless amusement.” 
Question 19. What about using 
ground phosphate rock “float” as. a citrus 
grove fertilizer. 
Mr. Poole: Several years ago a con¬ 
siderable number of groves were fertil¬ 
ized by ground phosphate rock, but in 
more recent years very little of the ma¬ 
terial is being used. 
Capt. Rose: The ground soft phos¬ 
phate rock compares favorably with 
Thomas Slag in the availability of phos¬ 
phoric acid. 
Question 20. How many applications 
of fertilizer do you think best 'for a 
grove ? 
Mr. A. IT. Brown makes about three 
applications of fertilizer to his groves. 
The first application is made in June, the 
second in October and the third in Janu¬ 
ary, varying the formula according to the 
time of the year. Making the formula 
high in the nitrogen for the January ap¬ 
plication and high in potash and phosphor¬ 
us for the October application. 
Mr. Poole makes six applications to 
young trees, making the first application 
in February, the second in April, the third
