Growth Regulators Applied / Height graph

Graph shows projected plant heights during production of the crop. Dots are plotted actual height each week. Arrows indicate when PGRs are applied with details in the weekly notes. We use the “late” graphical tracking curve and heights are from bench to height of growing tip. Heights are plotted from date of pinching to projected date of finish.

Red Elf November 16th11/16

This crop of Red Elf has finished on schedule, but is about 2 inches short. The crop schedule was too short and it would be better to start this variety about 14 days earlier. An additional problem was the very unusual cooler temperatures and lower light levels from the hurricanes that came during the important vegetative growth period between pinch and initiation. In other areas and crops, we are seeing this effect on other lower vigor varieties that are already on a short schedule.

Red Elf  November 9th11/09

This crop will be finished next week.

Red Elf  November 2nd11/02

This crop should finish in a couple of weeks be well developed short plants.

Red Elf  October 26th10/26

These plants continue spreading more than growing in height. We still anticipate them finishing at about 11 inches.

Red Elf  October 19th10/19

These plants are filling out more now and the more spreading growth habit is starting to show. They should finish at about 11 inches but with large bracts.

Red Elf  October 12th10/12

First color is starting and it is clear now that this crop is not going to make the size objectives. The schedule is too short and 1-2 more weeks of vegetative time was needed.

Red Elf  October 5th10/05

This crop continues to look good and is displaying its compact growth habit.

Red Elf  September 28th9/28

Red Elf is another early variety that is showing the first blush of color now. So, we need to let it go and see what it does.

Red Elf  September 21st9/21

This crop is not likely to jump on us, so we did not spray this week.

Red Elf  September 14th9/14

Lateral growth on Red Elf is good now. We will wait to see when the first spray is needed.

Red Elf September 7th9/07

Red Elf is a naturally shorter plant, but is not a weak plant. It has a slightly rounded habit and is uniformly flat on top. Height control should not be a problem.
