I want to grow Sun Red nectarines but do not know the chill hour requirements for my area. I know the chill hours for other fruits as I already grow peaches, plums, pears, all citrus and other varieties of fruit. Can anyone help with sun red? they will be planted in zone 9b. Thanks

The best way to find out how many chill hours your average is to ask your local AgriLife Agent. This site gives you an approximation, but remember as you approach the dividing line between section the number of chill hours goes down. You appear to average between 200 and 400 hours. These are averages so some years you'll get more and some years you'll get less.

Here's their site link:

I just found a link that lists Sun Red as recommended for your zone:

I would still recommend you contact your AgriLife agent . You are so close to the coast and that big body of water can really temper both the highs and lows. You may not really come close to the 400 hours. If the fruit trees don't get the required amount of chill hours, you won't get fruit, the trees' health will decline and they will eventually die or fall prey to a disease. There are a number of fruit that are labeled "low chill" because they need less than 200 - 300 chill hours. They would be your best bet if you want fruit every year. One thing most of us here in Texas forget and that is how late our last frost can arrive. The later the trees bloom the greater the chance of getting fruit. My Fuyu persimmon is my most reliable fruit producer because it blooms so late in the spring even though it only requires 100 chill hours.
