Romaine not bunching

Westbrook, CT(Zone 6a)

Although my leaf lettuce is growing like gangbusters, I have a problem with my Romaine lettuce plants. They don't seem to form tight bunches. They have a leaf then an inch higher on the stalk, there's another leaf on the other side, and so on. Plenty of leaves but I'd like to see them form bunches they way they are packaged in the grocery store. (I planted Cimmaron and Parris Island.)

The lettuce area only gets 5 or 6 hours of sun in summer, but it doesn't seem to affect the leaf lettuce. Any ideas on how to make the Romaine bunchier?

Do you have a picture?

It is one of three things:

1. Plants are too close together. Romain needs a good 10-15" between plants.

2. Sounds like it could be starting to bolt. Temperatures above 80F with long days can cause lettuce to bolt and never form heads. Romain is one that is a little more tolerant of heat but I have seen it bolt this time of year.

3. Or not getting enough sun? Lettuce grown is too much shade will not form compact heads.

They were about 8" apart, and showing no signs of bolting yet, so I'm inclined to suspect your cause #3. Next year I'll try to steal some space in the flower garden where there is more sun! Thanks!

I grow Parris Island. The need cool night temps to for a head/bunch. Maybe wait for fall?
