Pollination

Self-pollinating — one plant is all you need

Ruby Supreme Guava Tree sets fruit with its own pollen, so a single plant will produce a full crop on its own. You don’t need a second variety to get fruit.

Planting another compatible variety nearby can still nudge yields a little higher, and pollinators like bees always help — but it’s a bonus, not a requirement.

FAQ

Common questions

Ruby Supreme Guava Tree FAQs

1. What are the key benefits of the Ruby Supreme Guava Tree?

The Ruby Supreme Guava Tree is a fantastic addition to any garden due to its delicious fruit and ornamental value. It produces sweet, aromatic guavas with a beautiful pink flesh that are perfect for fresh eating, juicing, or making desserts. Additionally, the tree is known for its attractive, glossy green leaves and fragrant white flowers, which can enhance the aesthetic appeal of your garden.

2. How do I care for my Ruby Supreme Guava Tree?

The Ruby Supreme Guava Tree thrives in full sun and well-drained soil. Regular watering is essential, especially during dry periods, but be careful not to overwater as guava trees dislike waterlogged conditions. Fertilize the tree every two to three months with a balanced fertilizer to encourage healthy growth and fruit production. Prune the tree to maintain its shape and remove any dead or diseased branches.

3. When and how can I harvest guavas from the Ruby Supreme Guava Tree?

Guavas are typically ready to harvest when they change color from green to a lighter green or yellow and emit a fragrant aroma. The fruit should feel slightly soft when gently squeezed. To harvest, simply twist the fruit off the tree or use a pair of scissors or pruning shears to cut it from the branch. Guavas can be enjoyed fresh or stored in the refrigerator for up to a week.

4. Can I grow a Ruby Supreme Guava Tree in a container or indoors?

Yes, the Ruby Supreme Guava Tree can be grown in a container, making it suitable for patios, balconies, or even indoors with sufficient light. Growing in a container allows for easier mobility and control over soil conditions. Ensure the container has good drainage and is large enough to accommodate the tree's root system. Place the tree in a location that receives ample sunlight, and move it indoors if temperatures drop below 30°F.

5. Does the Ruby Supreme Guava Tree require pollination?

The Ruby Supreme Guava Tree is self-pollinating, meaning it does not require another tree to produce fruit. However, having more than one guava tree can increase fruit yield through cross-pollination. Bees and other pollinators can help with the pollination process, so creating a pollinator-friendly environment in your garden can be beneficial.
