about 3ft. apart, and allow from 18in. to 2ft. between the 
tubers in the rows. Keep clear of weeds; and, as soon as the 
foliage is yellow, in the latter part of the autumn, the roots 
will be fit for use. The best plan with this crop is to leave

it in the ground till wanted, or till the end of February, 
and then to take up every tuber, replanting those which 
are wanted for stock, and storing the others away in a cold 
dry place. When they commence 
growth, they turn black, and are of 
little use for cooking, save for fla- 
vouring soups. 
The Jordadlik Artichoke (see Fig. 
152), has of late years grown into 
favour as a marketable crop, and the 
demand seems to be increasing. 
Considering its very easy culture, it 
is a fairly remunerative vegetable.

are adapted for cuttings; and suckers may be utilised 
when procurable, which is very rare.
