ANSWERS TO 



CORRESPONDEISrTS. 



CLAEKIAS IN POTS.— S. W., Leicester: 

 I have some small seedlings of clarkias, and 

 should like to grow them in pots for autumn 

 house decoration. How should I proceed?- — 

 Pot each seedling in a small pot, using a 

 fairly rich, free compost. Grow in a cold 

 frame and afford ample light and ventilation, 

 and removing the lights during fine days. 

 A second shift will be needed, and 48 or 

 32-sized pots will suffice for this, the former 

 for preference. Provide a neat stake as 

 each plant begins to extend, and when the 

 larger pots are full of roots, afford weak 

 liquid cow manure once or twice a week. If 

 you have sufficient plants, divide them into 

 three batches, giving one set the brightest 

 position you can afford, and transferring 

 them to a greenhouse fairly early, affording 

 ordinary frame culture for the second batch, 

 and preserving the smallest seedlings for a 

 cool position. By this means the flowering 

 season will be extended. 



FAILING RED CUEEANTS.— M. E. H., 

 Cambridge: In my garden there are a num- 

 ber of quite old red currant bushes; ap- 

 parently they have not received very kindly 

 treatment ; consequently the fruit-s they 

 bear are small, and by no means plentiful. 

 Do you think it would be a good plan to re- 

 move the bushes and plant young, healthy 

 trees in their places in the autumn? — As soon 

 as the fruits have l^een gathered grub up 

 and burn the old, debilitated currant bushes, 

 and at once deeply trench the plot they have 

 occupied, working in a plentiful supply of 

 half-decayed manure and burnt refuse from 

 the garden fire. If this is done at once the 

 ground will be in excellent condition to re- 

 ceive the new plants as early in the autumn 

 as you can secure them. A new site would 

 have been preferable, but with deep trench- 

 ing and manuring, and an annual free top- 

 dressing of manure, the currants should do 

 well if the side branches are kept spurred 

 baek so that each long main branch resembles 

 a cordon. 



SLUG WOBMS ON EOSES.— H. S., Chels- 



field : Can ynu p,lease tell me of a remedy for 

 the eradication of enclosed pest from my rose 

 trees? The little yellow-green larvae have not 

 left one green leaf on a rose bed containing 

 fifty plants. I shall feel very grateful for 

 an answer through your columns. — The pest 

 is the rose slug-worm (Eriocampa rosse), and 

 one that is capable of doins: a vast amount of 

 harm in its larval stage. It attacks all kinds 

 of roses, and is a common pest in manv Euro- 

 pean countries, and also in North America. 

 The eggs are laid in May or early June bv 

 the adult winged sawfiy, but two or more 

 broods mav ])e hatched out in one season, 

 hence the not d of great care once there has 

 been an infestation. The ]>est remedy is 

 he]Ie]>ore wash sprayed over the rose trees, 

 so as to wet every portion ; the larvae only eat 

 out the upper epidermis and tissue of the 

 leaves, rarely eating the lower epidermis, 

 but they drop quickly from leaf to leaf, 

 hence the need for spraying so as to reach 

 every portion of each tree, and consequentlv 

 every larva. The hellebore wash is made by 

 mixing loz. of freshly gfround hellebore and 

 2oz. of flour, with a little water, until a 

 smooth, thin paste is formed, and then add- 

 gradually enough water to make up three 

 gallons of mixture. This wash must be kept 

 well stirred during use, and must also be 

 distributed in the form of a very fine spray.
