SPECIAL MANURES 223 



leaves, but not over the blooms.^ If tbe soil is defi- 

 cient in phospboric acid, sodium or potassium phos- 

 phate should be included in the liquid manure (|-oz.). 



Rhus or Sumach is improved by using a 

 manure containing guano, magnesium sulphate, 

 kainit, and iron sulphate. 



Rose Trees ^ are greatly benefited by means 

 of a liquid manure containing J oz. of litne 

 superphosphate, and |- oz. each of iron sulphate and 

 ammonium sulphate to 2 gallons of water. This 

 manure should be applied once a fortnight from 

 April to August to outdoor roses, and once a week 

 to pot and climbing roses indoors. Liquid manures 

 should be applied at the roots and not over the 

 foliage and blooms. With's Carbon Manure and 

 With's Eose Manure are also valuable for the 

 growth of rose trees. 



It is an advantage to place farmyard manure 

 round rose trees in the winter. It protects them 

 against cold, as there is little sunshine in England, 

 and rose trees love the sun. In the words of the 

 late E. L. Stevenson : 



" Late lies the vnntry sun a-bed, 

 A frosty fiery sleepy-head 

 Blinks but an hour or two ; and then, 

 A blood-red orange, sets again."
