Extending your season

I was wondering if anyone knew of methods to increase a tree fruit and berry season.
My only thoughts would for the early season cultivars to be in sunny spots and late season varieties in the shade.
I also read on permies about using rocks in shallow water to act as thermal storage. Would a tree planned next to one of these shallows experience an earlier spring or later fall.
Also would the light reflected by the pond also offset the daylight and dark cycle a little?
Any other ideas?

Water has a high specific heat capacity, so it will moderate the temperatures; similarly, rocks have a high thermal inertia. Water and rocks are good ways to store heat during the day and release it back out during the night which is why there are almost always breezes at the beach. I think plants located near the ponds and rocks might experience an earlier spring or later fall.

I think the light reflected off of the pond will increase the amount of sunlight reflected to the plants near it, but I do not think it will offset the day and dark cycles. If the light isn't there to begin with, increasing reflectivity might not help. Paul's thread on tefa (textured earth food all year-long) will be useful for figuring this out.

Does anyone know of a good resource or have any ideas on how far and how effect a given body of water is? For example I am slowly building a pond to slow runoff water from my neighbor's property and it is probably around 500 gallons, I assume this has a pretty minor impact on anything that’s not right next to it. I was hoping to find figure out if it’s worth trying to extend out the season for some woody perennials or if it would even make a difference- maybe a serviceberry, siberian pea shrub and hazel stand. Any thoughts or suggestions?

Paul has done a lot of writing on this, look up his lemon tree in montana stuff (I can't right now, will look later if I remember).

Water, rocks, wind protection--building a microclimate!

Thank you!

Here is the post I found to get started: lemon trees in montana
Looks like there is a related podcast I haven't got to yet I don't think:

There is also a hugelkultur documentary that might be helpful link

I did just start my first hugelkultur...I foresee a devious plot developing

I know what i'll be listening to on the way home!

My south facing hugelkultur warms up early and finishes late. In cool climates, mulch can delay spring warm up. It can also delay winter freeze. My absolute hottest spots are rock piles at the base of the hugelkultur and bare spots covered in dark coffee grounds. Once steps have been taken to create a warm micro climate, mulch manipulation adds a little more.

With fruit trees, it's important to not induce early flowering in areas where a late frost could ruin the crop. Trunks are sometimes whitewashed to delay flowering. The harvest season for the same cultivar growing side by side, can be stretched by painting some trunks while others remain bare. Shade and elevation difference can greatly effect fruiting time. I have harvested Himalayan blackberries in July on sunny slopes and in November on north facing, windswept slopes.

I have found out another way to influence the period of fruiting: watering.

You need several trees of course.
For example I have strawberry guavas. I love them because they have the colour and so the antioxydent of blueberries.
And they produce "only" twice per year!

Mine are late this autumn, because i stopped watering when in flower. They fell down... And it reflowered when I started to water again.
A citrus tree will also flower after some extra watering.
