Pruning the vines should be copied from the system followed in produc¬ 
ing espalier fruit trees, the branches supported and guided each by its 
own wire; the wires may be 24 to 36 inches apart, horizontal or perpen¬ 
dicular, according to fancy or convenience. 
If the soil where you intend to plant your Wistaria is not so good 
as you would like it to be, and that is frequently the case near a building, 
dig a hole 2V2 Met wide, 2 feet deep, and replace the old soil with new 
field soil, or improve the present soil with old manure, leaf mold, peat 
moss, and the addition of sifted coal ashes or sand if the soil is too heavy. 
Before planting the vines, fill in the new soil completely and dig a small 
hole in the surface after the new soil has been packed. Set your new 
vine 4 to 6 inches deeper than the graft. The graft can be seen as a 
swelling just above the roots. In the case of the larger vines, set them 
8 to 12 inches deeper than before, tramping the soil firmly after spreading 
out the roots. In fair soil, no fertilizer is required for several years. If the 
weather is dry, watering should be done. 
Wistaria can be grown successfully whether your soil is acid or 
alkaline, light or heavy, sand or clay. In sand they bloom sooner. 
Regardless of age they will not produce flowers of worthwhile quality 
the first year. Some of the larger plants may produce a few undersize 
flowers. The Standards we list should bloom the second year. The 
Chinese Standards are almost certain to bloom the first season. 
October, November and December are good planting months, as 
well as March, April and May. If potgrown vines are used, the planting 
season begins in March and ends generally December first. 
Newly planted Wistaria are not likely to come into leaf promptly. 
Therefore, be not uneasy when the vines appear to be dead. Excess 
watering is no help. Shading with muslin and sprinkling with water may 
be an advantage, but probably not necessary. 
Wistaria plants may be produced from seeds, layers or grafts. If a 
definite variety is to be reproduced, production by layering or grafting 
is necessary. Vigorous plants may be produced from seeds. Seedlings 
frequently produce flowers when they are six or seven years old, but 
occasionally it takes much longer before they get into production. A few 
seedlings here and there have not produced flowers during the first 
twenty years, but they should bloom some time or other, sooner or later. 
We are experimenting with a certain chemical, as there seems to be 
distinct indications that this chemical hastens production of bloom. 
It is a very easy matter to make Wistaria grow after it becomes 
established. All you have to do is to supply fertile soil and ample mois-
