Receiving a live Pink Guava plant

A rooted young plant has already passed through germination, but it needs a quiet transition from the shipping box before stronger sun, transplanting or feeding.

Unpack
Open promptly and inspect the stem, foliage, container and actual medium moisture.
Initial light
Begin in bright filtered light, then introduce direct morning sun gradually over one to two weeks.
Water
Water according to the medium, not the calendar; soak thoroughly when needed and drain fully.
Transplant
Wait until the plant is stable unless drainage is failing, then step up one pot size with the root ball intact.
Feeding
Begin light balanced feeding only after active growth resumes.

Pink guava identification

Leaves
Opposite, oval, prominently veined leaves with a slightly leathery texture.
Bark
Smooth and mottled, flaking to reveal lighter patches — a reliable field character.
Flowers
White flowers with a prominent brush of stamens, typical of Myrtaceae.
Fruit
Rounded to pear-shaped berry containing numerous small hard seeds embedded in the pulp.
Aroma
Ripening fruit is strongly and unmistakably perfumed.

Yellow skin, pink flesh

The source fruit behind these seeds matures to a yellow exterior and opens to rosy pink interior flesh.

Exterior
Green while immature, turning yellow as the fruit matures.
Interior
Pink to rosy pulp; the colour comes from naturally occurring carotenoid pigments.
Flavour
Sweet to pleasantly sweet-tart, varying with genetics and maturity.
Seeds
Numerous small, hard seeds concentrated in the central pulp.
Variation
Seed-grown offspring may differ in skin colour, flesh colour and intensity, size, flavour and aroma.

Pink guava vs other guavas

Common guava
Psidium guajava — the species sold here; larger fruit, pink or white flesh depending on the individual tree.
Strawberry guava
Psidium cattleianum is a different species with much smaller fruit and different foliage. These seeds are NOT strawberry guava.
Flesh colour
Within Psidium guajava, flesh colour ranges from white and cream to pink and red between individual trees.
Cultivar status
No named cultivar is claimed for these seeds; they are sold based on the source fruit.

Seed preparation and sowing

Cleaning
Rinse away pulp residue; leftover pulp encourages mold in the germination tray.
Optional soak
Guava seed has a firm coat, so a 12–24 hour soak in clean room-temperature water is commonly used before sowing.
Medium
A fine, airy, free-draining seed-starting mix, for example coir or peat generously opened with perlite.
Depth
Sow shallowly at about 1/4 inch, or surface-sow and cover lightly.
Moisture
Keep evenly moist without saturation; bottom watering avoids displacing the small seed.
Warmth
Warm conditions favour germination; cool, wet medium slows it and raises seed-rot risk.

Germination expectations

Timing
Germination time varies with seed condition, temperature, moisture and growing environment; emergence is often uneven across a tray.
Patience
Keep trays warm and evenly moist rather than discarding them early.
No guarantee
No germination percentage is guaranteed; results depend on conditions and handling.

Seedling care, light and temperature

Light for seedlings
Bright light once emerged so seedlings grow stocky, with shelter from harsh all-day direct sun at first.
Light for trees
Established guava performs best in full sun.
Temperature
Warm tropical and subtropical conditions throughout; avoid cold, damp conditions for young plants.
Air movement
Gentle circulation reduces damping-off in crowded trays.

Soil and watering

Soil
Guava is notably adaptable but performs well in suitable well-draining soil of reasonable fertility.
Drainage
Free drainage matters more than richness; avoid chronically waterlogged roots.
Establishment
Keep consistently moist while young plants establish.
Ongoing
Afterwards water according to the actual moisture of the soil rather than a fixed schedule.
Mulch
A mulch layer clear of the trunk helps stabilise soil moisture outdoors.

Transplanting and container growing

When to pot on
Once seedlings have several true leaves and a sound root system, keeping the root ball intact.
Container size
Step up gradually; oversized pots hold excess water around small root systems.
Long-term containers
Container culture works with adequate root volume, free drainage, consistent feeding and regular pruning.
Repotting
Refresh the medium and manage root volume periodically as the plant grows.

Fertilization and pruning

Feeding
Feed lightly and regularly during active growth with a balanced fertilizer rather than heavily and infrequently.
Young plants
Newly germinated seedlings need very little; begin feeding only once they are growing actively.
Structural pruning
Shape while young to build a strong, open framework.
Size management
Guava responds well to pruning, which keeps the canopy open and the tree in proportion to its space or pot.

Flowering, pollination and fruit development

Flowers
White flowers with prominent brushes of stamens, borne on current growth.
Pollination
Flowers are visited by bees and other insects; both self-pollination and insect cross-pollination are reported, and cross-pollination is often associated with better fruit set.
Fruit development
Fruit swells and shifts from green toward yellow as it matures.
Time to fruit
Seed-grown trees need maturity before flowering, and timing varies widely with genetics, climate, soil and care. No fruiting age is guaranteed.

Harvest and ripeness

Colour
Mature fruit of this type turns yellow on the outside.
Aroma
A strong guava perfume is one of the most reliable ripeness signals.
Feel
Fruit softens slightly as it ripens; fully hard green fruit is immature.
After picking
Guava continues to soften off the tree and is best used promptly once fully ripe.

Cold protection

Sensitivity
Young tropical guava plants are sensitive to freezing and prolonged cold.
Protection
Shelter seedlings and young trees from frost and cold wind.
Cooler climates
Grow in containers that can be moved under cover before cold weather arrives.

Seed-grown genetic variation

These are seeds, not grafts or clones, so offspring are not genetically identical to the parent tree.

What can vary
Fruit size, shape, skin colour, flesh colour and intensity, flavour, sweetness, aroma, seed content and productivity.
Why
Sexual reproduction recombines parental genetics, and guava is commonly cross-pollinated.
Practical approach
Growing several seedlings gives a better chance of finding an individual you like.
No guarantee
No fruit colour, flavour, fruiting age or yield is guaranteed.

Growing pink guava step by step

  1. 1

    Prepare the seed

    Rinse away any remaining pulp residue and let the seed surface dry briefly. Pulp left on guava seed encourages mold in the germination tray.

  2. 2

    Soak (optional)

    Guava has a firm seed coat, so many growers soak the seed in clean room-temperature water for roughly 12–24 hours before sowing. Discard the water and sow promptly.

  3. 3

    Mix a light medium

    Use a fine, airy, free-draining seed-starting medium — a coir or peat base opened up generously with perlite works well.

  4. 4

    Sow shallowly

    Guava seed is small. Sow about 1/4 inch deep, or press onto the surface and cover lightly, then firm gently.

  5. 5

    Keep evenly moist

    Maintain steady moisture without saturation. Bottom watering or misting avoids displacing the small seed and reduces surface crusting.

  6. 6

    Provide warmth

    Warm, tropical-style conditions favour germination. Cool, wet medium slows emergence and increases the risk of seed rot.

  7. 7

    Be patient

    Germination time varies with seed condition, temperature, moisture and environment, and emergence is often uneven. Keep trays warm and moist rather than discarding them early. No germination percentage is guaranteed.

  8. 8

    Light the seedlings

    Once seedlings emerge, give bright light so they grow stocky. Very young seedlings appreciate protection from harsh all-day direct sun.

  9. 9

    Pot on

    Move seedlings into larger containers once they have several true leaves and a sound root system, keeping the root ball intact.

  10. 10

    Grow on in sun

    Established young trees perform best with abundant sun, free-draining soil and consistent — not waterlogged — moisture.

Common problems and fixes

Seed fails to emerge

Likely cause: Sown too deeply, medium too cold, or the tray dried out.

Fix: Sow shallowly at about 1/4 inch, keep the medium warm and evenly moist, and allow more time — guava emergence is uneven.

Mold on the medium surface

Likely cause: Pulp residue left on the seed plus stagnant, saturated conditions.

Fix: Rinse seed thoroughly before sowing, water from below, and improve air movement around the tray.

Seedlings collapse at soil level

Likely cause: Damping-off in crowded, over-wet, poorly ventilated trays.

Fix: Reduce surface wetness, thin crowded cells, and increase gentle air circulation and light.

Leggy, stretched seedlings

Likely cause: Insufficient light after emergence.

Fix: Move to brighter light promptly, keeping harsh all-day direct sun off very young seedlings.

Yellowing leaves on a young plant

Likely cause: Waterlogged roots or nutrient shortage during active growth.

Fix: Check drainage first and let the medium dry slightly, then feed lightly and regularly if growth is active.

Leaf damage after a cold spell

Likely cause: Exposure to frost or prolonged cold in a young tropical plant.

Fix: Move containers under protection before cold weather, shelter from cold wind, and wait for warm-season regrowth before pruning damage.

Flowers but little fruit

Likely cause: Poor pollination, plant immaturity or stressful conditions.

Fix: Encourage pollinators, keep water and feeding consistent, and allow the tree more maturity. Fruit set is not guaranteed.

Frequently asked questions

What is Pink Guava?
Pink guava is common guava, Psidium guajava, of a type whose fruit has pink or rosy interior flesh. The source fruit for these seeds matures yellow on the outside and is pink inside.
What is the scientific name of guava?
Psidium guajava L., in the family Myrtaceae.
Is Pink Guava Psidium guajava?
Yes. Pink guava is a pink-fleshed form of the common guava species, Psidium guajava.
Why is the fruit yellow outside but pink inside?
Skin colour and flesh colour are controlled separately. This type ripens to a yellow exterior while the pulp carries carotenoid pigments that make it pink or rosy.
Is this Strawberry Guava?
No. Strawberry guava is Psidium cattleianum, a different species. These seeds are Psidium guajava.
What is the difference between guava and strawberry guava?
Psidium guajava is the common guava with larger fruit and larger leaves; Psidium cattleianum, strawberry guava, is a distinct species with much smaller fruit and different foliage.
What other names is guava known by?
Guayaba and guayabo in Spanish, guayaba rosada for the pink-fleshed type, goiaba and goiabeira in Portuguese, goyave in French, bayabas in the Philippines and jambu biji in parts of Southeast Asia.
How many seeds will I receive?
The quantity you select: 25, 50, 100 or 1,000 seeds.
Can I choose the quantity?
Yes. One listing offers 25, 50, 100 and 1,000 seeds, and free shipping applies to every option.
Is this listing for seeds, fruit or a live plant?
Seeds for planting only. No fruit and no live plant are included.
Is fruit included?
No. The guavas in the photographs illustrate the source fruit and the mature species. FRUIT IS NOT INCLUDED.
Are these seeds from pink-fleshed guava?
Yes. The seeds were sourced from guava fruit with a yellow mature exterior and pink/rosy interior flesh.
Will every seed-grown tree produce identical pink fruit?
No. Guava grown from seed shows natural genetic variation, so fruit colour, size, flavour and other traits may differ from the source fruit. No fruit-colour guarantee is made.
Is this a named cultivar?
No named cultivar is claimed. These are seeds sold on the basis of the source fruit, and they are not grafted, cloned or genetically identical to the parent tree.
How should guava seeds be planted?
Sow shallowly at about 1/4 inch in a fine, airy, well-draining medium, then keep it warm and evenly moist in bright light.
Should guava seeds be soaked before planting?
Soaking is optional. Because the seed coat is firm, many growers soak for roughly 12–24 hours in clean room-temperature water before sowing.
How long can guava seeds take to germinate?
Germination time varies with seed condition, temperature, moisture and environment, and emergence is often uneven. No fixed number of days or germination percentage is promised.
What temperature is suitable for germination?
Warm, tropical-style conditions are preferred. Cool, wet medium slows germination and increases the risk of seed rot.
Does guava need full sun?
Established trees generally perform best in full sun. Very young seedlings should be protected from harsh all-day direct sun and acclimated gradually.
Can guava grow in a container?
Yes, particularly while young. Long-term container culture requires adequate root volume, free drainage, consistent feeding and regular pruning.
How large can Psidium guajava become?
It develops into a small tropical or subtropical fruit tree or large shrub. Final size depends on genetics, climate, soil and pruning, and container plants stay much smaller.
What soil does guava prefer?
Guava is adaptable but performs well in suitable well-draining soil of reasonable fertility. Good drainage matters more than richness.
Can guava tolerate cold weather?
Young tropical guava plants are sensitive to freezing and prolonged cold. Protect them from frost and cold wind, and grow in containers in cooler climates.
How long can a seed-grown guava take to fruit?
Seed-grown trees need to reach maturity first, and timing varies with genetics, climate, soil and care. No fruiting age is guaranteed.
Does guava require another tree for pollination?
Both self-pollination and insect cross-pollination are reported in guava, and cross-pollination is often associated with better fruit set, which is why some growers raise more than one tree. Fruit set is not guaranteed.
How do I know when guava fruit is ripe?
This type turns yellow on the outside, develops a strong guava perfume and softens slightly. Fully hard green fruit is immature.
What does pink guava taste like?
Highly aromatic, with flavour ranging from sweet to pleasantly sweet-tart depending on genetics and maturity.
How is guava used?
Fresh eating, juices and nectars, smoothies, jams, jellies and guava paste, preserves, desserts, pastries and sauces.
Does guava have health benefits?
Guava is commonly noted for vitamin C and dietary fibre, and Psidium guajava has a long ethnobotanical history and has been studied scientifically. This is educational information only, not medical advice, and no treatment claims are made. The product is sold as seeds for planting.
