rectly in a frost-proof coldframe, as
lilacs can be grafted. All seven grafts made good growth, that is, over
three inches, by early May, but failed later. There is only one alive
today, I do not think this an impossible method, but there must be a
better way of handling to give success, such as attention to shading and
careful watering. One may find more on this subject in "Propagation of
Trees, Shrubs, and Conifers," by Wilfrid G. Sheat.
In our greenhouse work we have used several nutrient preparations, with
poor to good results. There is one that has proved quite remarkable, and
may be of use to the nut grower. Our concern has been to promote
greener, healthier leaves, and the product "Ra-Pid-Gro" is most
outstanding. Our tests in regards to nut growing are very limited. A pan
of Chinese chestnut seed mixed in pure sand was set under the greenhouse
bench last winter. The seed sprouted too early to be planted out, and
trees have been left inside. Since the sand had no food value,
Ra-Pid-Gro was applied to the leaves, allowing the drippings to go into
the sand throughout the summer. Today, the little seedlings are indeed
nice. Outside, a Persian walnut had yellow-toned leaves, and Ra-Pid-Gro
was applied--now the leaves are green! It is amazing how quickly yellow
leaves will become green. This appears to be a very useful product.
_I believe we can have scions too dormant to graft!_ Last winter I had
to make a new scion-box for storage, so copied it after the Harrington
method, sinking it in the ground north of some evergreens. Scions have
kept perfectly--maybe too perfectly--because they were absolutely
dormant at grafting time, and have given poor success. It was rather
late to save scionwood when I received an order to cut some of Mr.
Hostetter's "Special Thomas" wood, so I cut a little extra for myself,
and some wood from a little seedling Persian walnut that I wished to
hasten by topworking. The buds were very much swollen that day, and the
terminal buds were partly expanded. At grafting time I was quite
surprised to find the wood I had cut late to be in exactly the same
condition as it was the day I cut it. When grafted, every scion
grew--all nine grafts made of the little Persian walnut were smaller
than a lead pencil--and were _pithy_ as well! This experience is so
encouraging, I hope to have most of my wood in this advanced condition
another year. Absolutely dormant wood might well be brought out of
storage s
