Fall
is the prime time for planting of hardy spring
flowering bulbs. Bulbs and perennials need plenty of water and good
drainage. If water has a tendency to stand in the planting area, you’ll
want to break up hard sub-soil and put in a layer of drainage material
such as coarse gravel, broken stone or sifted cinders below your
surface soil.

Summer-blooming
Dutch bulbs and perennials are not fussy about soil – provided it is
not too heavy and sticky. If soil is heavy, loosen it with lots of
humus, sand, gypsum, etc. If very light, add moisture holders – humus,
peat mold, etc. If you have a soil with a high clay content, it can be
improved by adding compost, peat moss or some other source of organic
material. The organic material should be worked in the top twelve
inches of soil (eighteen inches is even better).
