GARDENERS' CHRONICLE 



THE GREENHOUSE MONTH TO MONTH 



{Coutinnrd from page 51 ) 



post of mushroom bed ni;imirc, a little sand and moss; 

 divide the rhizomes into moderate sizes and phice in flats. 

 Cover them with the compost but do not water ; the 

 moisture 'n the rose house will ^ive them a good start. 

 This is far better th.an starting them by the usual method 

 m dry pots. 



The next batch of achimenes can be started in baskets. 



Clean olt the sour soil of carnation beds, gently stirring 

 the surface, and give a fair sprinkling of bone flour. 

 Top dress with one inch of tine loam and well rotted horse 

 manure, and you will realize the benefit to the plants as 

 the days lengthen and the sun strenglhens. 



Repot into three-inch ])ots any 'mums that recpiire a 

 shift. Do not allow any check or the buds will be devel- 

 oped from stunted plants and their season interrupted. 

 Keep them very cool. 40 degrees at night and day, if pos- 

 sible, is desirable. If other plants are grown in the 

 house, they nmst be subservient to the "mums, or the latter 

 will be ruined. The last batch of cuttings should be in- 

 serted this month and the old stock thrown out to make 

 room for the new. Fumigate regularly to keep clear of 

 aphis. 



Cclosia spicafa is a subject useful for house decoration. 

 easily raised .ind will withstand draught and dust better 

 than ordinar\- kinds. 



Lantanas and Bouvardias that are rooted in sand should 

 lie potted and grown along in gentle heat. The weeping 

 Lantana is a fine specimen for han.ging baskets or pans. 



The sweet peas should have a good mulch of sheep ma- 

 nure and loam, equal parts. Remember the best sweet 

 peas or rather the earliest are better if sown in pots in 



.March in a temperature of 55 to 60 degrees. They will 

 germinate in ten daj's. Grow them along gently in the 

 same temperature until weather conditions are suitable 

 for their removal to cold frames. 



Give the last batch of cauliflowers a dose of nitrate 

 of soda, a very li.ght sprinkling, or a watering of a tea- 

 spoonful to a gallon of water will do nicelv.
