Noticed that yesterday. I have 3 apples very close to one another, all get roughly the same sun/etc. The McIntosh and Cortland are showing red (from the flowers) and the Sweet 16 is silver tip.

We're assuming that they're all alive and healthy, right? None of them are dead or dying?

I guess I don't have a good answer why two of the same kind side by side would develop at different rates. Are they on the same type of rootstock? -- that could have an effect, I would think.

I have seen the same thing here. Sometimes, I think it's because I have heavier mulch application around one tree compared to another. That can delay bud break a bit.

I general I found out that early apples bud out first,.. then late apples. I like the later one's...keeping late frost damage to a minimum.

I've been curious about how many chilling hours you far northerners get; yes, I know it gets stinking cold, but how many hours between 32 and 45 degrees? Could it be lack of hours in this temperature range?

Many apples that do well in the far north also do well here in Southern California, and even the tropics; Wealthy, Honeycrisp, and White Winter Pearmain are all quite reliable here (and tasty too).

I'll look into that and see what they are for here in La Crosse.

We get a LOT of that temp range in the fall (Sept/Oct/Nov)...

Interestingly, where I'm at, all my apple trees bloom at about the same time (Westland, Chestnut, Noret, McIntosh, Honeycrisp, Goodland, Kerr, Prairie Magic, Hazen, State Fair, Carroll, September Ruby, Zestar, Parkland), usually not until early June. The blooms on some last longer (eg., Honeycrisp). Our growing season is short--I've not been able to get Hazen, Honeycrisp, or Prairie Magic to ripen properly, and some years Goodland and McIntosh don't fully ripen, either. It would be helpful to have a good chart that gave days from bloom to ripen.
