TRELLIS or TREILLAGE, is an 

 arrangement of supporters upon which 

 to train plants. 



Espalier Trellis. — The cheapest, the 

 easiest, and soonest made, is that 

 formed with straight poles or stakes, of 

 proliferum. This, like the Ciboule, is j ash, oak, or chestnut, in lengths of from 

 without a bulbous root, but throws out i five to six or seven feet, driving them 



numerous offsets. Its top bulbs are 

 greatly prized for pickling, being con- 

 sidered of superior flavour to the com- 

 mon onion for that purpose, as well as 

 others in which that species is employed. 

 Tiine and Mode of Planting. — It is 

 propagated both by the root offsets, 

 which may be planted during March 

 and April, or in September and October 



in the ground in a range about a foot 

 distant, all of an equal height ; and then 

 railed along the top with the same kind 

 of poles or rods, to preserve the whole 

 form in a regular position. They should 

 be full an inch and a half thick, and 

 having pointed them at one end, drive 

 them with a mallet into the ground in a 

 straight range, close along the row of 



and from the top bulbs, which are best] trees, a foot deep at least. To render
