| Grapes -
Concord |
| Dormant |
 |
No visible indication of growth. |
| Scale Cracked |
 |
Scale Crack (SC), is the first visible indication of growth.
A small crack occurs between the hard outermost bud scales as the bud begins to swell. |
| Early Bud Swell |
 |
During First Swell (S-1), the bud has swollen out of the hard
outer bud scale and is globular, light brown (doe-colored), and fuzzy. No green or pink is
visible as of yet. |
| Late Bud Swell |
 |
When Full Swell (S-2) occurs, the bud has elongated (about
1.5 to 2 times as long as wide) one or more bulges of leaf tissue are visible and appear
green or pink. The bud remains closed around the growing point. |
| Bud Burst |
 |
During the fourth step, Bud Burst (B), the leaves have
separated at the tip, usually exposing the growing point. No leaf is, as yet, at a right
angle to the growing stem. |
| 1-3" shoots |
 |
Expanded Shoot (ES) is the final step and occurs when the
stem is 4-6 cm in length with 1-3 small leaves at right angles to the stem. |
| 4-8 " shoots |
 |
Shoots are 4 to 8 inches long. Three leaves are out on this
stem and 2 flower clusters are exposed. |
| 10-16 " shoots |
 |
Shoots are more than 8 inches long. Flower Clusters are
clearly visible. Many Growers talk about the number of leaves out perpendicular to
the shoot. |

First flowers open. |
| Bloom |

Berry Touch or cluster tightening is when the berries begin
to touch and it becomes impossible to protect the interior of the bunch from pests and
diseases. |
