will grow in damp and shade. Cystopteris is a 
very easy Fern to cultivate ; it will suit itself to 
almost any locality. Osmunda requires damp and 
shade. Polystichums, and Polypodiums and Allo- 
sorus need sun. All Ferns must have good 
drainage. I always mix good garden earth with 
the soil of old banks, the debris of trees, &c. I 
water nearly every day during the summer. 
Do not be afraid of Ferns. They like being 
moved and divided, and will forgive almost any- 
thing but neglect. 
Never plant a Fern upon a rock or stone ; there 
must always be depth of soil with drainage beneath. 
If a Fern does not do well in one situation try it in 
another, but never see a plant looking unhappy 
without trying to find out the cause, and seeking 
to remedy it.
