Growing Feijoa (Pineapple Guava) in the Pajaro Valley
If you garden in the Pajaro Valley around Watsonville, the feijoa, or pineapple guava, is an easygoing fruit that fits the warm valley well. It handles the heat, the soil, and the rare valley-floor frost without complaint, making it one of the simpler fruits to add here.
Quick verdict: A good, reliable choice. The Pajaro Valley's warmth and rich soil suit the feijoa, and its strong cold-hardiness means even the valley's frost pockets are no real threat. Pick a self-fertile variety, or two varieties for heavier crops, give it sun and decent drainage, and it largely looks after itself.

Why the Pajaro Valley suits feijoa
The Pajaro Valley is the county's warmest agricultural microclimate, sheltered enough to build real summer heat while keeping some marine moderation, and blessed with deep, fertile soils. Those conditions grow a strong, productive feijoa. Unlike a frost-tender avocado, the feijoa is not troubled by the valley's one quirk, the cold air that pools on the flat floor on still winter nights, because it is hardy to around 10F, far below anything those frost pockets produce. So a feijoa here gets the upside of valley warmth and good soil without the frost-pocket worry that complicates more tender fruit. The only nuance worth naming is flavor: feijoa is often most aromatic in cool coastal air, so a valley feijoa is excellent and heavy-bearing, though a foggy coastal one may have a slight edge in fragrance. If you have read our local overview, gardening in Watsonville and the Pajaro Valley, the feijoa is one of the lower-maintenance fruits you can grow in the pocket.
When to plant in the Pajaro Valley
Plant in spring once the soil has warmed, or in early fall, both of which suit the valley. The feijoa's cold tolerance makes timing forgiving, and unlike avocado you do not need to fret over which frost pocket you plant in. Spring planting gives a young plant the full warm season to establish. If your ground is very low and damp, simply choose the better-drained part of the lot.
Self-fertile versus cross-pollinated varieties
This is the key choice. Some feijoa varieties are self-fertile and fruit alone, while others crop best with a second variety nearby for cross-pollination. For a single-plant garden, choose a reliably self-fertile variety such as Coolidge, Apollo, or Pineapple Gem. Even these crop more heavily with a different variety nearby, so plant two if you have room. The valley's warmth and good pollinator activity help fruit set, but a partner variety remains the surest path to big yields, especially with larger-fruited types like Mammoth.
Sun, soil, and water
Sun: Full sun for the best crops, which the valley supplies generously. Feijoa will take light shade but fruits best in full sun.
Soil: The valley's rich, deep soil is a genuine asset for this adaptable plant. Feijoa is not fussy but appreciates good drainage and organic matter, so avoid the heaviest, wettest patches or improve them before planting.
Water: Regular water during establishment and through fruit set and sizing gives the best crops. Warm valley summers mean it drinks more than a coastal feijoa, so water deeply and let the top few inches dry between soaks. Established plants are fairly drought-tolerant once their roots are down.
Shaping the plant
Feijoa is naturally a multi-stem evergreen shrub and can be kept as an informal hedge or screen or trained into a small single-trunk tree. In the warm valley it grows strongly, so decide the form you want early and prune to it. Its silvery evergreen foliage and showy edible flowers make it a useful landscape plant as well as a fruit, handy along a property edge or driveway.
What to expect from the fruit
- Aromatic, sweet-tart green fruit tasting of pineapple, guava, and mint, ripening in fall.
- Fruit that drops naturally when ripe rather than needing to be picked off the plant.
- Edible, sweet spring flower petals to enjoy before the fruit forms.
- Generous, dependable crops on an established plant, especially with a second variety nearby.
Common questions in the Pajaro Valley
- Light fruit set: usually pollination. Add a second variety and welcome the bees and birds that pollinate the flowers.
- Knowing when it is ripe: ripe feijoas fall from the plant. Gather them off the ground or shake the plant gently.
- Vigorous growth: the warm valley pushes strong growth, so prune to keep the hedge or tree form you want.
- Heavy or wet soil patches: improve drainage before planting in the lowest, dampest ground.
Local tip: The feijoa is one of the few fruits in the Pajaro Valley you can plant almost anywhere and trust to thrive, since its cold-hardiness sidesteps the frost-pocket question that worries avocado and citrus growers. Use it where you want a tough, productive evergreen, plant a self-fertile Coolidge or Apollo with a second variety if you can, and enjoy the fall harvest.
Frequently asked questions
Do I need to worry about valley frost pockets with feijoa?
No. Feijoa is hardy to around 10F, well below anything the Pajaro Valley's frost pockets produce, so the cold air that worries avocado and citrus growers is not a concern here. You can plant it in spots that would be too risky for tender fruit.
Do I need two plants to get fruit?
Not necessarily. Self-fertile varieties such as Coolidge, Apollo, and Pineapple Gem fruit on their own. Every feijoa crops more heavily with a second, different variety nearby for cross-pollination, so plant two if you have the space.
Does the warm valley affect the flavor?
Feijoa fruits heavily and tastes very good in the warm Pajaro Valley. The fruit is often at its most aromatic in cool coastal air, so a foggy coastal feijoa may have a slight fragrance edge, but a valley feijoa is excellent and far more productive than many heat-loving fruits.
How do I know when the fruit is ripe?
Ripe feijoas drop from the plant on their own in fall. Rather than picking firm fruit, gather the fallen ones or gently shake the plant. The fruit is ready when it yields slightly and smells fragrant.
