Do blood orange trees need cross pollination in coastal California? If so, what is the cross pollinator?
Answers:
I have looked on a few sites for you, and I cannot find anything that mentions cross-pollination.
Are you asking because your fruit is not red, or you have no fruit at all? If you have no fruit at all, did you grow it from a seedling? (they can take 2 - 15 yrs to yield a crop)
Here are some quotes and links:
Blood oranges are supposed to have a dark rose pulp, but this can be modified by climate. In Southern California, the typical pulp color occurs when blood oranges are raised in desert areas, e.g., in the Coachella Valley, but homeowners who grow blood oranges in coastal Orange and Los Angeles County are disappointed to discover that the pulp is orange, not red.

Healthy trees and a sweet, delicious harvest are the goal as you tend your oranges throughout the year.
Steps:
1. Purchase an orange variety adapted to your area. For example, Washington navels grow well in California, while Valencia oranges are adapted to Arizona, Texas and Florida, as well as California.
2. Plant the tree in a warm, sunny area where the soil drains well.
3. Mulch to conserve water.
4. Water the tree deeply once every 7 to 10 days in midsummer. Water less often if it rains or if the weather is cool.
5. Fertilize every four to six weeks from February to August.
6. Protect trees from frost if temperatures are forecast to drop below 28 degrees F.
7. Harvest oranges when they taste sweet. Timing will vary by variety and growing area.
TIPS:
Most nurseries in citrus-growing regions offer a nice selection of container-grown orange trees.
You can grow citrus from seeds, but there's no guarantee that the seedling will be identical to its parent. A seedling can take from 2 to 15 years to bear fruit.
Warnings:
The more likely that winter temperatures will fall below 28 degrees F where you live, the less likely you'll harvest a quality crop.
