Next, size up your plants as to height—larger and bolder plants for the background or for accent, creepers for blending. In between should come the many flowering and foliage plants that make your garden a thing of beauty.
Many of these plants can be bought at florists’ shops or variety stores. Others are available by mail, including the wildlings. The woods are always a source, but conservationists urge all of us not to destroy plants carelessly or move them out of their native haunts to unfavorable locations.
I find that the plants available from mail-order specialists are reasonably priced and are always good sturdy stock. More on this in Chapter 13.
PLANTING AND CARE
Whether your glassed-in garden is an artistic arrangement of plants or an actual garden, give your design a tryout by placing the plants on a temporary basis. Put them in place and appraise the arrangement. Don’t rush. You’ll save time by not having to do it over later.
In the case of containers rounded on the bottom, line them with thin sheets of moss. Turn the green side out. Next add an adequate layer of pebbles or sand, for drainage. A sprinkling of broken charcoal is particularly desirable. The close humid air may cause soil to grow “sour” without it.
Soil may be acid or not, heavy or light, sandy or humus-rich. It all depends on the type of plant to grow in it, and it will be moist when you use it. Please, make the soil deep enough to give the plants root-room. If you want to make it interesting, build it up gently into slopes or natural mounds. Flat land is dull, not nearly so interesting.
As you put in the plants, add the stones, pebbles, paths, or pools—whatever you have in your design. May I warn you—don’t dirty the inside of the glass. Once dirty, it is almost impossible to clean up later. Plant sparsely. Remember, your plants are going to grow. The finishing touch will be the addition of “sod” or moss on the bare areas. Most of the suggestions for dish gardens and model landscapes in earlier chapters apply here. Finally, polish the glass and spray the plants with a fine mist to clean off any soil that may be on leaves and stems. Water very gently.
According to tradition, partridgeberry bowls are arranged differently. The base of the bowl is lined with moss, and covered with drainage layers, charcoal, and then soil. Then the berried plants and any others to be combined with them are placed, one layer at a time, with their faces against the glass. Their roots are toward the center and covered with soil. Finish the top layer facing up; sprinkle any loose berries on top; mist the foliage gently; cover with glass, and deck out with a big bow of Christmas ribbon.
For a few days after planting, set a terrarium where the light is not bright. After that, it needs light or sunlight according to the requirements of the plants. If they grow lank, limp, and leggy, they are usually stretching out for more light. Window-sill plants may lean toward the window—remedy: simply turn the terrarium around, and alternate it every few days so that both sides get an equal share of light.
