A General Purpose Rock Garden Soil
  The gardener knows that there is nothing like coarse, gritty sand for the drainage of a soil. He uses it in his bed cut into the soil he mixes for potting soil. Sand, is one of the ingredients.
  The roots of rock garden plants, as we have seen how to cling to the moist surfaces of bits of stone buried in the soil, while the remaining leaves on the tracks, which made its way to the surface, so that direct contact with the dirt.
  An important component will be stone chips. Regular gravel, as is used for the surface treatment is suitable roads, this can be readily used in most sections. If not, bank gravel, preferably not too fine or smooth, and not "washed", serves as a substitute.
  For our third ingredient, we humus or decayed vegetable matter, which is almost always in the ground, in the rock grow plants. This material is an additional supply of moisture, in addition to the equipment some plant food. For the supply of humus, granulated peat moss is best. It is slightly acidic so that only the extreme lime-loving plants on the object, and it absorbs moisture and holds more than a similar material.
  Moreover, it is absolutely pure and free from weed seeds, an advantage that can not be overemphasized in rock garden planting. Peat Moss is easily available everywhere, but if you do not happen to have finely sifted leaf mold will. Commercial humus has a tendency rather than a top of the wet or soggy.
  Fourth, and finally, to provide additional authority for the plant food that we good light garden loam. This should, however, quite free from clay, this is the last thing in the nature of the soils that are used if rock units are to go.
  All this has required some time in to say, but if you cook it on them. To reach a satisfactory all around rock garden soil, mix thoroughly together the following:
  1 part clean, gritty sand, 1 part stone chips, or clean, gritty gravel, 1 part granulated peat moss, or sifted leaf mold, 1 part clean, light garden loam.
  You have a ground in which 90% of the rock plants, you will probably try to start will be satisfactory.
  Special soil for specific purposes
  Occasionally, however, you can find plants that are somewhat different than those cited in the question of the earth, this will be reflected in the above mixture, but grow better if their tastes be taken into account.
  Some insist, in an extremely acidic soil, lime or soil, are to survive. Such facilities can either be used as they are by themselves, or are in bags filled with earth, their own special dietary requirements.
  These special blends are ground up using the following rules, the heads of the changes is an increase in one part or one of the various ingredients. These proportions are approximate, there is no need for weighing the ingredients into a jeweler's scale.
  Acid soil
  1 part sand, 1 part stone chips, 3 parts acid leaf shape (ie, leaf form is collected under evergreens, laurels, or the like), lime or sweet soil 1 part sand or 3 parts old plaster, 1 part loan, 1 part peat moss
  Dry soil.
  3 parts sand, 2 parts stone chips, 1 part loam, 1 part peat moss
  Moist soil.
  1 part sand, 1 part chips, 1 part loam, 3 parts Sphagnum moss or granulated peat moss, or both
  Fertilizers
  For plants that are not the true rock-and alpine-like garden annuals and herbaceous plants, shrubs, evergreens, and most of pear and also those of the rock or alpine plants as easily to a somewhat stronger diet, often decayed manure and bone meal can be added to the general soil mixtures suggested above.
  For evergreens, shrubs or other plants that are around the rock garden, with a background or context, the terms are usually for them, of course, be given. Especially if a specialty garden features have been added, as in the collection Williamsburg, http://technorati. com / videos / youtube. com 2Fwatch%% 3Fv% 3D9HrZ2bNaiGk.
  Do not use commercial fertilizers, except bone meal, and even with this great caution.
  Lime is not a fertilizer, but can occasionally for the rock garden. If old lime rubbish, it's better for this purpose is not to have ground limestone or gypsum may be used, a soil otherwise too sour.
  Aluminum sulphate, now supported by most seed houses, in the opposite direction. This can be used either to neutralize a lime soil, or by applying in larger quantities to the soil acidity reacts. Acidic sheet tool that in most sections, if a problem is to hunt them.
  Leaf mold, under oak trees is sufficiently acidic, for most purposes, if decayed laurel leaves, conifer needles, leaves or rhododendrons are not to have.
