The picture below explains the lapse in blog posts. The week mentioned in the previous post turned into a month. The early shoot growth stage starts off at a very vigorous pace which is hard to keep up with. At this point of the season we have gone through bloom and fruit set. The weather has been dry and warm over the last month making the conditions for bloom and fruit set perfect. With the weeks of warm weather and very little rain we now have to monitor the vines for signs of drought stress. The forecast shows a chance this weekend; all we can do is hope for a bit of rain.
With warming temperatures, White Birch is ramping up its preparation for summer. Our tasting room is now open seven days of the week and will soon feature over a dozen wines to enjoy. Our winetail list is ever expanding, with a wine float in the works for hot summer days. With our white wines hitting the shelves in a few weeks, the reds are expected to be on the shelves by summer’s close.
The season is starting to jump into full swing with shoot growth tripled since this photo taken May 25th . The weather has been dry helping ease early pressure from the fungal spores that like tender vinifera shoots and leafs. We did get a bit of rain followed by hot sunny weather that pushed the vines and weeds into full gear. Julio, our other full time vineyard worker, and I have been moving dirt to disrupt the weeds from growing over the past week. Soon it is time to tuck the shoots into the wires and tie the new shoots from the base of the vine up so they do not lie on the ground. Stay tuned for an updated picture that shows what a week’s worth of growth can be.
The younger vines are pushing their way to the fruit wire. The vines in the pictures were planted last spring and should produce fruit in a couple seasons. Vines can be injured in various ways; the most common over the last few seasons has been the cold temperatures. Currently we are pruning out the old wood to promote the growth of the buds we had covered with dirt. After the old wood is pruned we tie the canes to the fruit wire to try to control the placement of the fruit. If the fruit is not uniform in the fruit zone it is hard to manage the fruit throughout the season.
The grapevine buds are compound buds each containing three buds. The primary bud contains the most flower clusters, the secondary fewer clusters, and the tertiary bud contains no flower clusters. The three buds are varying in cold hardiness. The primary bud is least cold hardy, the secondary is a bit hardier, and the tertiary is most cold hardy. The picture above is of two of the three buds pushing out of a cane that was buried in the dirt. In regions where the temperature does not damage the buds, the secondary and tertiary buds are normally plucked off early in the growing season to prevent crowding of the fruit zone.
