How to Grow Guava from Seed
To grow guava from seed, you will need optimal conditions such as sunlight, soil, and water. Growing guava from seed can give you a rewarding experience. It grows slowly from a seedling and becomes a large, fruit-bearing plant. To grow guava from seed, it will require 3-8 years to produce fruit. Also, seed-grown guava may not always be the same as the guava tree from which you took the seed.
7 Steps to grow guava from seed
1. Collect Seeds
Use seeds from fully ripe, healthy guava. After removing the seeds, wash off all the pulp with fresh water.
2. Prepare the seeds
Soak the guava seeds in warm water for 24 hours to improve germination. You can also lightly rub the seed coat with sandpaper to speed sprouting, as it softens the seed. Rub only a small spot of the seed; do not rub the white inner part, as it can damage the embryo. After you rub the seed with sandpaper, soak the seed in warm water for 24 hours.
3. Plant the seeds
Fill a pot with well-draining soil. Sow the seeds about 0.5–1 cm (¼–½ inch) deep. Cover the guava seed lightly with soil.
4. Keep warm and moist
Place the pot in a warm location (around 25–30°C / 77–86°F). Provide the pot with warm and bright indirect sunlight. Also keep the soil evenly moist, but do not water too much, as it may waterlog the pot.
5. Wait for germination
Guava seeds usually germinate between 2 and 8 weeks. Some take longer to germinate.
6. Transplant
After germination, when there are 4-6 true leaves, move them to a larger pot or outdoors. Make sure the climate is frost-free.
7. Care for the plant
Give the guava plant 6-8 hours of sunlight daily. Water only when the topsoil of the guava plant begins to dry. Also feed with balanced fertiliser every 1-2 months during the growing season.
Tip: If your goal is fast fruit production with predictable fruit quality, a grafted guava plant is usually a better choice than growing from seed.
Frequently Asked Questions
How long do guava seeds take to germinate?
Most guava seeds germinate within 2–8 weeks.
Do guava seeds need sunlight to germinate?
No. They germinate best in warm, moist soil. After sprouting, seedlings require bright light.
Can I plant seeds directly outdoors?
Yes, in warm tropical or subtropical climates. However, starting seeds in pots offers better control and higher germination success.
Is growing guava from seed better than buying a grafted plant?
Growing from seed is inexpensive and enjoyable, but grafted plants usually produce fruit sooner and more reliably.
