GARDENERS' MAGAZINE. 



Editorial communications should be addressed to the Editor of the Gardeners' 

 Magazine, 148 and 149, Aldersgate Street, E.C. 



Aehleaf Potatos.— W. S., South Wales : The tubers sent are fine hand- 

 some ones for this early date, and large as well. They do not represent any form 

 of the Ashleaf Kidney with which we are acquainted, and are much too robust to 

 belong to that variety. What the variety is we cannot tell at present, as the tubers 

 are not mature, and there are no opportunities for proper comparison at this 

 season. The variety is worth taking care of as an early sort for your district, 

 whatever it may be elsewhere. 



Black Spot on Tomatos.— J. R., Wigan : The attack is a rather bad 

 one of the dreaded Black Spot, a fungus known as Cladosporium lycopersici. 

 The fungus attacks the pistil, sometimes as soon as the young fruit has set, and from 

 this it radiates, forming a black flat patch over the apex of the fruit. Often the 

 attack is not sufficient to absolutely spoil the whole fruit for culinary purposes, 

 but it always renders it useless for sale. If allowed to ripen such fruits as you 

 have sent will be useless for food, while they will be serving to spread a trouble- 

 some fungus. The best plan will be to remove and burn all the affected fruits, 

 and any that subsequently appear with a black spot. Ventilate freely, and in 

 every way do all possible to maintain a buoyant atmosphere in the house ; a little 

 artificial heat will probably be necessary, as the nights are by no means warm as a 

 rule this summer. There is no remedy known to be effective without destroying 

 the plants, and we know of no preventive. Even in the best grown collections of 

 tomatos Black Spot sometimes appears, but affected fruits are removed as soon 

 as seen. 



Losses in Bedding Pelargoniums.— A. C R., Faversham : There is 



something radically wrong in the soil to make the pelargoniums die away as in 



the specimens sent, and as the plants have only been affected in a few places 



along the extensive border, it would almost appear as if foul play were the cause. 



An excessive application of some chemical manure would produce a similar result, 



especially if given in a liquid state, as it would burn up the roots and the 



stem below the ground line. This, of course, might happen by accident in the 



case of a badly-mixed liquid, where the last poured from the can would be 



immensely stronger than the first. We have seen an escape of both coal and sewer 



gas do similar injury, but in such cases the damage occurred in a restricted area, 



and almost in a straight line. We trust these remarks may help you to fix upon 



the cause of the mischief, and we suggest, by way of experiment, that in some 



cases you remove the soil at the points where plants died, replace it with new 



material, and plant again ; in others do not remove the soil, but plant again as 

 before. T 1 ^ '- e - - * ^ - 



Let us know the result if you make the experiment.

A concise yet excellent handbook, equally useful to the amateur, the practical gardener, 

 and the grower for market. The subjects dealt with comprise all the m)St important plants, 

 fiowe»s. fruits, and vegetables, and each of the chapters is written by a horticulturist who is not 

 only master Of the subject, but is able to discuss the details in a manner that cannot fail to 

 merest his readers."— Gar^emts* Magazine. 



1 n^* L V S Successful Gardening' is a well written and useful work, teeming with 

 valuable information. Its publication will, I am sure, make clear to thousands the great differ- 

 ence j-tween the proper use and the abuse of Clay's Fertilizer, which I have long regarded 



as a perfect plant food, and continue to use largely. In tteJ^j^SS^^ 

 day is at hand when Clay's will be in every garden in Great Kntam.
