I have a planting of Red velvet that was pinched about 16 days ago . The branching on these plants are about 1/2" long ,they seem to be growing very slowly.They were treated with florel twice.Roots seem to be ok and waiting for soil analysis.Should I be concerned?

What rate did you use with the Florel? Where any other growth regulators applied prior to pinch?

What is your fertility program like?

Where were the roots in terms of establishment when the plant were pinched?

FLOREL was applied twice once before the pinch and once after at a rate of 1 tbs / gal.

They have been fertilized with 250 ppm poinsettia fertilizer and also alternated with 15-0-15.

The roots were not to the sides of the pot, just getting to them.

Other plants on the same bench were pinched later and have passed these up in vigor.

Florel does have some mild growth regulator effects but with the low rate you used it shouldn't be the reason for the slow growth.

Were any PGR’s applied prior to the pinch?

With the slow growth are you seeing any distortion or hardened growth? How much phosphorus is in your fertilizer?

If the roots aren't established well when the plant is pinched sometimes the new shoots can get off to a slow start. This is because the plant is prioritizing its energy output to rooting first. Once the roots reach the edge of the pot and begin to circle energy goes to shoot growth. Now that a few days have gone by hopefully the root system has really taken hold and the new shoots are showing more vigor.
