Guava Tree Propagation
Growing Guava from Cuttings
Guava is propagated from cuttings and seeds. Growing guava from cuttings require specific temperature and humidity, this method is suitable in warm climates.
Growing Guava from Seeds
Guava seeds are propagated easily with high germination rate. The main thing is that they must be fresh and obtained from the quality source. You can also use seed fresh seeds collected from the fruit but it is better to buy seeds from a seed store or online.
If you are using seeds obtained from guava fruit. Firstly, rinse them in soft water, which is not very cold then wrap the seeds in a cloth and dry them for a couple of hours. Then pour them in a cup of warm water and soak the seeds for 3-4 hours. Prepare a pot filled with seed starting mix, and sprinkle seeds in it. Now put the pot on a warm, well-lit spot, like a windowsill. To speed up germination, you can install a small plastic or cellophane over the top of a pot.
Guava tree grown from seeds take 3-4 years to mature and start to form fruits. From cuttings, it grows more quickly. However, our recommendation for you is to buy a grafted guava tree. Most of the grafted trees start to bear fruit in the same year and remain healthy.
Choosing a pot
Guava tree grows large (around 30 feet) but in pots, it can be reduced to 2-3 m. Choose a pot that is at least 3 gallon (10 inches) to provide the plant a sufficient space to grow roots. *It is best to choose a clay pot with sufficient drainage holes in the bottom.

Requirements for Growing Guava Tree in a Pot
Guava loves the sunny and warm exposure. It is a tropical plant but very much adaptable to temperate climates with moderate winter, when grown on the ground.
If you are growing guava in a container in tropics you can choose a location that receives shade in the afternoon and at least six hours of sun daily. In colder zones, place the plant in a spot that receives full sun for healthy growth and more fruiting.
For growing guava in pots choose a quality potting mix or make your own substrate using equal parts compost, sand, and soil.
Growing guava is possible in a variety of soil types. It is one of the plants that tolerates different soil types easily. It can be grown in heavy clay-rich or very sandy soil with pH ranging from 4.5 (acidic) to 9.4 (alkaline), but a loose, well-drained soil that is rich in organic matter and neutral to slightly acidic in pH is optimum.
When growing guava in a pot choose a self-pollinating variety.
The optimum temperature for germination of guavas falls in the range of 68 to 82 F (20 to 28 C). In winters, the temperature must not fall below 27 F (-3 C) for young guava trees. Mature guava tree (at least 3 years old) can bear temperature down to 20 F (-6 C). Remember, guavas are not frost tolerant, especially young plants, so if in a climate where the temperature falls below the range given here then it is better to keep the plant indoors until the temperature rises up.
When the plant is young or forming flowers water it regularly and deeply to keep the soil slightly moist. Evenly moist soil at the time of fruiting helps in developing more juicy and sweet fruits. In winter reduce the watering. One of the most interesting facts about guava trees is that they are drought tolerant and once established they can survive only on rainfall and bear long periods of drought. Still, it better to keep the soil slightly moist.
Guava Tree Care
Guava tree care is simple and easy and with a few basic information, you can grow a healthy plant.
Pruning guava is essential to keep guava tree growing in a pot in desired shape and size to develop a strong structure, healthy plant and increased fruiting.
Dry, dead, damaged or diseased branches can be pruned anytime. The crowns grow naturally and well-branched and do not need regular cutting. Best is to cut back too long, unbranched shoots and branches that are crossing each other and blocking the penetration of sun rays after the harvest or at the beginning of growing season.
Whenever the first time your guava tree blooms to form fruits it is better to deadhead the flowers, never allowing the fruits to set (do this if your plant is weak).
Allow no more than 4 fruits per branch. Also, thin out the fruits if they are developing on a small and weak branch.
Repot the plant in one size bigger than the previous one. Never plant a plant in a too big pot directly, albeit change the pot time to time once the plant has outgrown the current one.
Guava responds well to the monthly fertilizing. When the tree is young and is not bearing fruits, fertilize your potted guava tree with 6:6:6:2 [N P K Mg] to speed up the growth of the plant.
When the tree starts to bear fruits change the composition to 8:3:9:2 [N P K Mg].
Guava tree is also susceptible to iron deficiency (symptoms includes yellowing of the leaves in between the dark green veins). It can be corrected or prevented by periodic application chelated iron.
Do mulching with organic matter so that the plant retains moisture. Mulching also helps in insulating the root of guava tree in winter.
Pests and Diseases
Guava tree care from pests and diseases is not much required when grown in a pot. This fruit tree is very tough but you should keep an eye on common garden pests. Mealy bugs, guava scale, white flies, fruit flies and thrips can affect it.
In diseases, guava plant suffers from rust, which occurs in too warm weather and high humidity.Besides this, anthracnose and leaf spot can be a problem too, both of these occurs in wet humid weather and spread through splashed water. By proper irrigation, you can easily prevent this.
Most of the guava tree varieties are self-pollinating and fruit ripens year round in tropics (except summer). Guava fruits usually mature in 3 to 4 months after flowering.
In India, generally, the main crop arrives in winter and after the summer in the rainy season. Winter crop is more flavorsome and sweet.
Guava fruits taste better when picked earlier than they fully mature. Fruits are highly nutritious, rich in vitamin C and can be eaten raw, its seeds are edible too. Ripened fruits can be used to make guava ice-cream, juice, jam, chutney, sauce or desserts.
A Few Guava Tree Care Tips
- Do not abruptly change the location of your potted guava tree otherwise the plant may lose leaves (partially).
- To get a bushy plant, it is necessary to pinch the growing tip regularly.
- It is advisable to suspend the fertilizer during the winters. In tropics, you can continue it.
