CALENDAR OF OPERATIONS 217 



Heart " varieties sown last August will now be ready 

 for cutting. Those sown in February will be ready 

 for planting out about the middle of the month. 



Lettuces. The " Passion " variety, planted in 

 January, will now be nearing maturity, and the space 

 between each plant may be filled with a Cauliflower. 

 The frames and lights may be taken away altogether 

 from these crops, if necessary, about the end of the 

 month, and used for a second crop of Melons. 



Melons. Those already in frames require careful 

 ventilation each day when the weather is fine. Seeds 

 should be sown each week to have plants ready later 

 on for the beds as they become vacant. 



Celery. Make a sowing early in April, and prick 

 out 3 in. apart in May on an old hot-bed. These are 

 to follow Cauliflowers. Young Celery plants may now 

 be placed in frames, from which Turnips, Radishes, 

 and Carrots have been gathered. 



Lettuces. The Cos varieties grown on hot-beds will 

 require attention. As the earlier plants are nearing 

 maturity, the cloches covering them should be removed 

 to cover the plants next in order of ripening, as ex- 

 plained at p. 163. 



Carrots. During this month attention must be given 

 to weeding and thinning out, as the plants grow quickly. 

 If necessary, the frames may be raised 2 or 3 in. by 

 placing bricks or blocks of wood at corners, but manure 

 should be previously banked up round frames to 

 prevent soil from falling down afterwards. 



Celeriac. The young plants from seeds sown at end 

 of February or early in March will be ready for pricking 

 out on south borders or on an old hot-bed.
