336 GARDENING FOR BEGINNERS

 hardiest. 



Ferns in Wardian Cases. Practically the only satisfac- 

 tory Ferns for Wardian cases are the Filmies ; all others are 

 apt to get drawn or to outgrow the limited space. Our native 

 Filmy Ferns (Hymenophyllum tunbridgense and Wilsonii\ and 

 the lovely Killarney *Fern(Trichomanes radicans), of which there 

 are several beautiful varieties, do well in a perfectly close case 

 if pegged down on pieces of limestone or sandstone embedded 

 in an open peaty compost. After pegging down, this should 

 be covered with a handful or so of sandy compost and then 

 watered overhead so heavily that this mulching is washed well 

 into them, thus establishing them firmly, but not burying them. 

 This done, they may be left untouched for months together, 

 save a watering when needed. That beautiful New Zealand 

 Fern (Todea superba) makes a grand central plant if the case 

 be large, and it is hardy as grass. These Ferns must never see 

 the sun, and drought is absolutely fatal. They are the children 

 of caves and hollows by, and even under, waterfalls, and shrivel 

 at once if exposed to dry air or sunshine. The need for strong 

 light is consequently less, and hence they may be grown in 

 duskier situations than Ferns that love the air. Judiciously 

 aired and well lighted, the Wardian case may accommodate a 

 small rockery containing some of our small growing Spleen- 

 worts, such as Asplenium trichomanes and its varieties, which 

 constitute a pretty group, and will thrive provided the fronds 

 are not wetted and the plants be carefully installed in rocky 

 chinks, limestone for preference, soil sandy leaf-mould. Pretty, 

 temporary arrangements may also be made by filling the 

 bottom of the case with fresh cocoanut fibre and bedding 

 small thumb pots therein containing small growing specimens 

 of Hart's-tongues, Spleenworts, &c., which can easily be 

 shifted when growth renders it necessary. Good drainage 

 is essential ; water-logged soil breeds a sourness fatal to 

 everything. 



Perns in the Conservatory. Here, of course, we have 

 ampler room for our plants, but also different conditions. 

 Most conservatories are built for flowers, and hence placed to 



f^t as much sunshine as possible, and in such we find the 

 erns usually either ignominiously dumped under the staging 

 or stunted and out of condition by uncongenial baking. The 

 ideal Fernery under glass never sees the sun at all, a deep 

 ravine, as it were, with a glass roof. However, few of us being 

 millionaires, we must do with what we can get, and hence if 

 we have a conservatory attached to a house and facing north,
