In the spring I blogged about growing grape vines from cuttings for fall planting. You can go back to the previous blog to see how the cuttings progressed from May to present, - here is the May 2021 post and here is the June 2021 post.
We grow the cuttings in a 1 foot x 1 foot container in 2 inch by 2 inch sleeves. This gives us 36 vines per square foot incubator. The propegation rate was approximately 75% and would have been higher but we lost probably 10% due to the intense 44c heat we had in early July. However, of the cuttings that did grow into vines, we only planted out the best vines from each group. The result is about 65% of the cuttings were strong enough with big enough roots to move into the field. The other ones that were smaller and weaker are going to be left in the incubator and grown bigger next year and will be planted out in the field next fall.
In mid September the vines had achieved good growth over the summer and were ready to move from the nursery to the field. Here is a picture of the group of vines that have been extracted from the incubator. The roots are somewhat tangled and have to be gently separated. Once separated they can be planted in the ground.
This picture below shows the both the top growth and root growth of the vine that occurred from the cutting planted in may. All in all we planted out 1500 row feet this past week and we have another 1500 row feet to get planted in the next few weeks. Next spring we will plant 3000 more row feet of vines.
