YOUR QUESTIONS ANSWERED. 



I seem unable to make hollyhocks 

 grow in my garden because they soon 

 become diseased and look unsightly. 

 Must I give them up entirely? 



Novice. 



In his Hardy Flower Book, C. H. 

 Jenkins says that a cupful of salt dis- 

 solved in three gallons of water and 

 applied every two weeks in spring 

 with a syringe in a fine, mist-like 

 spray, is effective in controlling the 

 hollyhock disease. He says, however, 

 that the salt must not reach the roots 

 of the plants. We do not know of 

 anybody in this country who has tried 

 out this remedy, but if really effective 

 it seems to be an improvement over 

 bordeaux mixtures, which is most 

 commonly relied upon. It must be said 

 that bordeaux is not by any means as 

 efficient as we should like it to be. 

 Perhaps the simplest plant is to grow 

 new plants from seed each season, tak- 

 ing pains to give them an open loca- 

 tion where the air will circulate freely, 

 and using rich soil. Diseased plants 

 should be destroyed each year. 



What do you recommend for plant- 

 ing in the bulb beds to continue the 

 season of bloom? E. T. R. 



There are several shallow rooted an- 

 nuals which give a good account of 

 themselves in the bulb bed, and do no 

 harm to the bulbs. One of the best for 

 the purpose is the so-called annual 

 mallow or lavatera, which blooms 

 freely and has a small, attractive, mal- 

 low-like pink flower. The foliage as 

 well as the blooms is attractive. There 

 Is a white variety, but the pink kind is 

 better. Verbenas, heliotropes, pot 

 marigolds and similar plants may be 

 used in the same way. 



Can you give me a remedy for the 

 white grubs which feed on the roots 

 of my strawberry plants and do much 

 damage? S. P. 



It has been recommended that to- 

 bacco dust be dug into the ground to 

 prevent this trouble, but a better plan 

 has been tried out in Vermont, with 

 success. A strong decoction of tobacco 

 is poured upon the ground around the 

 plants, and seems to be very effective 

 in destroying the grubs. Of course 

 when new beds are made each year in 

 ground which has been cultivated the 

 year before, there is little trouble from 

 the white grubs. This tobacco water 

 treatment, by the way, is proving use- 

 ful in the vegetable garden, especially 

 In protecting melon and cucumber 

 plants. Little damage will be done by 

 the striped beetle if the liquid tobacco 

 is used on the ground close to the 

 stems.

Can you tell me what makes my 

 celery grow leggy and pithy? I used 

 manure freely at planting time and fed 

 the growing crop with liquid sheep 

 manure. Did I use too much of this 

 fertilizer? 



L. White. 



Who can tell? There are many 

 theories but few known facts about 

 the cause of pithiness in celery. Some 

 gardeners believe an excess of nitro- 

 gen makes the hollow stalks, yet good 

 celery is often grown where stable 

 manure is used with the greatest free- 

 dom. One expert believes that the 

 trouble commonly starts in the seed 

 bed, where the plants are allowed to 

 become too crowded. It is quite feasi- 

 ble to cut back young plants to make 

 them more stocky. Oftentimes a mulch 

 in the bed will do much to produce 

 good celery, especially if the summer 

 is a hot one. Professor Watts, of 

 Pennsylvania, has advocated spread- 

 ing a deep mulch of horse manure 

 over the beds, thus keeping the ground 

 cool, preventing the growth of weeds 

 and reducing the amount of labor.
