I have a Eureka lemon tree that gives lemons in the fall thru January. I would like to get another lemon tree that will give lemons in the spring/summer when the Eureka lemon tree does not produce lemons. I'm being told the Meyer lemon tree would be a choice. Is this correct? I don't want two lemon trees producing at the same time. I appreciate your help. I live in Vacaville, California
"Eureka" lemons can often be picked year round, but the primary season of harvest is from late winter to early summer. The "Lisbon" variety also produces fruit sporadically throughout the year, though the main season is in winter and early spring. The harvest of "Bearrs" lemons is heaviest in the months of July through December. "Meyer" lemons are a hybrid variety with sweeter juice, picked mainly from November to March, but is likely to have some ripe fruit at almost any time of year."
The fruiting period is not only related to the variety, but depends largely on the growing conditions (deep fertile soil, full sun, etc), soil and water management, as the article indicates.
In Vacaville you will have extreme drought conditions in the dry season through October. So it's important to have a good irrigation program during that time. Frequent irrigation as with lawns will cause root and crown rot. Drip systems are usually not adequate, citrus do best with deep flood irrigation every week or 10 days. Try to achieve 10 inches penetration of water into the soil profile. Mulch to help retain soil moisture. Fertilize with a slow release complete organic citrus fertilizer like this:
