ORANGES, LEMONS, AND LIMES POTTING AND TUBBING. 51 



most fibrous turf, shaking out the loose particles, and spread a layer over the drainage 

 to keep the compost from mixing with the crocks. Now turn the orange tree out of 

 its pot, remove the drainage, then pick out the old spent soil from the sides of the ball 

 with a pointed stick, and remove the surface soil down to the fibrous roots. Place 

 enough rough compost in the pot, so that when it is rammed down and the tree 

 resting with its base thereon, the upper part of the ball will be 1 to 2 inches or more 

 below the rim of the pot or tub, according to its size. The space all round, 1 to 2

inches, must be filled in with compost, and made rather firm with a potting- stick. 

 When the work is properly done the tree will have its collar slightly raised in the 

 centre of the pot or tub. The compost ought to be mixed a month or more before 

 being used, and be warm, but not too dry. Syringe the trees with tepid water, but take 

 care not to saturate the soil. Water will usually be required in about two or three 

 days after re-potting. An excess causes the compost to become sour, and the roots do 

 not take to it freely, the trees then being in a worse state than if they had not been 

 re-potted. Tubs may be made of oak, or preferably of slate, secured with galvanised
