I looked for this term, because somewhere I read that hosta can go heat dormant. I found only one place which mentions it, and it was the HL Don_R lists. The one specifically called Sun Tolerant Hosta.
"In areas where summers are very hot and dry, hostas should be planted in some shade, as the sun is just too intense. In these environments, hostas may go heat dormant for the hottest part of the year."
And that is where I am focused at this time. Where can I go to find more about the issues of heat dormancy for a normal hosta gardener who is not a pro? Me.
If they go heat dormant, say sometime around August dog days, is that the end for this year? Or will they emerge again as the weather cools in mid October, do their root growth in a big rush, and then assume it is winter along about January?
Last year, the nearly 20 hosta I had from Massachusetts underwent some dormancy in November before we hauled them to Alabama. This year, they will have to adjust to a different sort of seasonal cycle. I'm afraid to think how confused they might become--as well as myself.
Has anyone in the higher zone numbers encountered ANY heat dormancy? From a thread which BKay commented in, she indicated that her hosta in zone 8a basically observed the same cycle as in other parts of the country.
My original 20 hosta from last year are still in pots. The rest of my plants were purchased this year, now totalling upwards of 137. The three in the ground did not come up as early as those in containers. I'm watching to see if they also grow longer, or bloom and give up.
Anyway, point me in the right direction to read more about heat dormancy. Which must not be the same thing as death or winter dormancy...... should I do something to keep it from happening if at all possible? Is it a bad thing, or will the heat dormancy save their little green lives?
