Q: How does Red Strawberry Guava differ from common guava?
A: Red Strawberry Guava (Psidium cattleianum) is a distinct species from the common guava (Psidium guajava). It produces smaller, cherry-sized fruit with thin skin and pink flesh, while common guavas are larger with thicker skin. The flavor is more tart and aromatic, with distinct strawberry and passion fruit notes, whereas common guava has a more traditional, musky sweetness .
Q: When is the fruit ready to harvest?
A: The fruit typically ripens in summer to early fall (July-September in most regions). The berries are ready when they turn from green to deep maroon-red and yield slightly to gentle pressure. They ripen over several weeks, allowing for multiple harvests.
Q: How large does the tree get, and can it be kept small?
A: In ideal conditions, it can reach 15-25 feet tall and wide . However, it responds very well to pruning and can be maintained at 8-12 feet with annual shaping, making it suitable for smaller gardens and even large containers .
Q: Is it invasive?
A: Yes, in some tropical and subtropical regions (notably Hawaii, Florida, and parts of Australia), Strawberry Guava is considered an invasive species . It spreads readily by seed and can form dense thickets that displace native vegetation. Check local guidelines before planting, and in regions where it is problematic, consider growing it in a container or choosing a sterile variety if available .
Q: How should I grow it for the best fruit production?
A: Plant in full sun for the best fruit production, though it will tolerate partial shade. It prefers well-drained, slightly acidic soil but adapts to a range of conditions. Water regularly during establishment and fruit development. Fertilize with a balanced, slow-release fertilizer in early spring. Prune after harvest to maintain shape and size .
