Some of you may recall that I began experimenting with growing romaine in the local weather conditions. I initiated this experiment after discovering heat-resistant seeds, but so far, I have not achieved any satisfactory results as the plants have bolted. Recently, I decided to leave the seeds exposed to the harsh weather conditions during germination. At present, they appear promising, and I am hopeful that this attempt will be successful.
I throw shade cloth over my lettuces after spring is ending and temps rise. Seems to put off bolting for me for a bit longer
Thanks Logan, Clay_22 for the suggestion but I don't think that will work. I remembered in 2010 I planted them not in a full sun area and they bolted too. Yes here it is - Romancing the Romaine!! | Page 4 I remembered when I was staying in a organic farm in Luxemburg, we transplanted a few hundred romaine seedlings in summer and that year the temperature was soaring between 35°C to 40°C. Before transplanting we have to cut the leaves in halves and was told that they will have a better chance to survive. They were not shaded. I wasn't there long enough to see them grow to maturity and I am sure they grow well because that is a commercial farm. At the moment my romaine still looking good and I guess I just have to keep my finger crossed and hope for the best.
