In spite of the snow outside the greenhouse, the nuts are starting to wake up from their winter dormancy. I'm sharing a close-up profile of a chestnut germling below. We've planted over 4000 hazelnuts and 900 chestnuts to date.  We wait until they have germinated so that all seeds in a flat are nearly the same developmentally.  By doing so we can ensure watering and other treatments can be provided at near optimal timing for the entire population of plants in a flat. We use subirrigation via flood-able tables to ensure even water availability to the tublings.  If you are familiar with the leaf size of hazelnuts (or chestnuts) you can readily see how water from an overhead source could be deflected from reaching the surface (and interior) of individual tubes (white containers above and below).  In order to ensure good capillary action we presoak the flats after planting.  Included in this presoak is a combination of beneficial soil organisms in a produc...

We're spending a great deal of time right now watering - but only hazels (or other) that were planted THIS year.  Anything planted last year, for us, is not stressed - yet.  Though it might be.  Anything planted 2 years ago; we consider safe and not in need of supplemental water except perhaps in extreme circumstances (or on sandy soils, maybe). But; yes; this kind of extreme heat and dry weather can kill tubelings planted this year; they're still tiny. Get them watered if you have ANY doubts about it. Meanwhile: Our friend Hank Roberts made this comment on the last post: "I know you're too busy to be blogging these days, just thinking about y'all while watching the weather. I know a tiny bit about heat stress on corn and soy (both the limits during critical periods and the overall degree days, I think?), but nothing at all about what factors combine to affect success with your woody crops." Yah, busy, but it takes a while for the pickup water tank to fill; 45...
