CELERY AND CELERIAC 



After the plants have reached a full growth, 

 they should be blanched. The board method is 

 one of the best. Boards eight to twelve inches 

 wide, placed end for end, the edge close to the 

 plants and flat on the ground, may be lifted 

 carefully against pegs driven close to the plants 

 at intervals of five to eight feet to support the 

 boards. Another set of pegs or stakes are 

 driven on the outside of the board to keep 

 it in position. This is done on both sides 

 (A, in Fig. 56). By raising the board care- 

 fully there is little danger of breaking the 

 leaves. 



If the soil is a clay type it is a good practice 

 to run a strip of building paper on each side 

 of the plants and bring the soil up to it, leaving 

 the tops of the plants sticking out. The soil 

 may be pressed against the plants without the 

 use of paper (Fig. 54). There are many in- 

 ventions on the market for blanching celery 

 and these may be had from any seed store (Fig. 

 55).
