I've read a lot about continually adding organic matter to the soil, but if you're digging around in there, don't the plants become uprooted? Do you just mix it in the soil between the plants?

"Continually" an mean 'yearly' or 'seasonally' or 'before every time you plant', or 'whenever you want on a regular basis by side dressing' (put down a layer of compost around the main stem of the plant coming out in width as wide as the plant can potentially grow.

Also, I just read a post about not watering the garden..somthing that has never occurred to me. Unless it's rained, I water daily.

There is no need for you to water daily. Some people go so far as to think they'll be able to water each plant according to it's specific water requirements. It's ambitious to try to give each plant the exact amount of water it needs but not practical or necessary. Even if someone gave you a chart, it would still depend on the quality and friability of your soil as well as the stage of the plant.

So long as you have good drainage, the plants will take what water they need. General rule of thumb is that gardens require one inch of water per week by supplementing rainfall.

You will have to adjust throughout the season and be attentive to the amount of rainfall you receive each week. There are two schools of thought on watering. Frequent shallow waterings or less frequent long, deep waterings. The general rule of thumb is that mature plants need 1-2 inches of rain per week in summer. You should provide whatever portion of this moisture is lacking. One inch of rain equals 65 gallons per 100 square feet of garden space. But this is just a guide. Time of the season, stage of the plants, soil composition, and many other factors affect the amount of water required. Be consistent during fruit production.

Mulched plants require less water than plants that are not mulched. Raised beds require more than non-raised beds.

If a good amount of compost is incorporated into the soil, less water is needed. Compost holds 6 times it's weight in water.

Watering too frequently and too heavily is just as hard on plants as too little water. Roots require oxygen just as much as they require water and nutrients.

Dry winds dehydrate plants.

Cooler temps require less water.

It is always best to water in the early morning hours so that any water left on the plant can evaporate with the morning dew and not cause fungus or disease problems.

Those using drip irrigation whether from a soaker hose or milk jug are likely getting the best use of their water which is going right where it needs to go and the ground has time to absorb it.

There are hundreds of methods of watering. Whatever you do, just be consistent. Roots require oxygen equally as much as they require nutrients and water.

I personally believe in a couple of deep waterings per week with the use of 2 inches of mulch to reduce evaporation and maintain a more stable soil temperature.

Plants recover from dehydration much better then they ever recover from the roots being suffocated by drowning so under watering is better than over watering until you get the hang of it. Oxygen is equally as important as water and nutrients and rain water is always better than municipal tap water.
