How to Grow Guava Tree from Seed to Harvest: Check How this Guide Helps Beginners

Guava is a round or pear-shaped fruit 2 to 3 inches long. Ripe Guava contains sweet, moist flesh that is highly scented. Each fruit contains several small, hard, but edible seeds. Guava trees in tropical climates are 12 to 14 feet long but are kept in a container, and they remain small enough for a covered porch or small greenhouse. Commercial farmers use grafted trees to get specific fruit characteristics, but growing Guava from seeds in a home garden is an easy and fun way to add to the garden landscape.

How long does it take to grow Guava from seed?

  • Guava plants thrive in soil with good drainage and full sun to produce the best flowers and fruits and attain up to 20 feet in height. 
  • Although Guava can be grown from seeds, it will not be true to the parents, and it will bear fruit in eight years. Trees are more commonly propagated through cutting and layering. In this case, the fruiting of the Guava tree should occur when the tree is 3 to 4 years old.
  • The period between flowering and ripening is 20 to 28 weeks, depending on when the tree was pruned. Pruning is not the only factor determining when Guava trees fruit, however. The fruiting of the Guava tree also depends on the age of the tree.
  • Guava trees can bear fruit in 8 years when grown from seeds and continue this work for forty years. Guava trees can bloom throughout the year, but spring is the primary season. The fruit usually develops 90 to 150 days after the first bloom. When ripening, the fruit changes from green to yellow and becomes considerably soft.  

Can I grow Guava from seed?

  • While seed-grown Guava doesn’t reproduce true to type, it is an economical way to grow Guava and is not uncommon. 
  • You should plant Guava seeds immediately after extracting them from mature fruit. Guava trees are often propagated by seed or cutting. Either method is quite simple so choose which one works best for you. 
  • Plant your seeds or cuttings in the two feet-deep holes at the end of March. February-March or August-September month is an optimum time for planting Guava. Then, fill it with soil, but do not compact it so the roots have more space to spread. When it is young, water your tree 2 to 3 times weekly and fertilize it with organic fertilizer every three months.

How do you transplant Guava seedlings? 

  • You should plant seeds ¼ to ½ inches deep in moist, sterile soil. Keep the soil temperature consistent from 21°C to 29°C. Cool soil will significantly delay seed germination time, and soil temperatures below 15°C to 19°C will completely prevent germination.    
  • Gently lift the root ball and set it on an untreated natural burlap. Wrap the burlap around the roots, then move the plant to its new location. You should place the root ball in the new hole. When transplanting Guava trees, set them to a new location as deep in the soil as in the old place.

How do you grow Guava fruit faster?

  • In growing Guava from seed, the first step is to break the dormancy of seeds. This is done in two ways. Either you can place the Guava seeds in a pot of boiling water for 5 minutes, or you can soak the Guava seeds in water for two weeks before planting. Both of these seeds allow the coat to soften and thus hasten germination. 
  • Then cover the seed with only a small amount of seed starter mix. Place the pot in a warm place, and whenever the upper layer of the soil surface feels dry, keep it moist. It will take two to eight weeks to germinate.
  • Regular applications of Guava tree fertilizer are needed to keep this fast-growing plant to ensure the production of high-quality flowers and fruits. The use of Guava tree fertilizer with a 6-6-6-2 ratio is recommended.

Do Guava trees need a lot of water?

  • Guava often doesn’t need deep water. During hot weather and the growing season, water Guava is two to three times a month, deeply. Guava resists drought in the winter, so water sparingly. Guava has shallow roots and absorbs water and nutrients rapidly.
  • You should water young Guava trees 2 to 3 times weekly. However, once it matures, it won’t need as much water as it should be 2 to 3 times monthly. Guava trees are sensitive to waterlogging, so regulate what you give. 
  • Water to grow Guava trees every other day after planting and then once a week in the first year. Guava trees appreciate deep water but let the soil dry before you re-water. It also likes good organic mulch. 
  • Guava trees can tolerate brief periods of flooding, but if the soil remains wet continuously for more than 7 to 14 days, the tree can suffer leaf and fruit drops, yellow leaves, twig dieback, and even tree death.

Does Guava tree need full sun?

  • Guava plants thrive in soil with good drainage and full sun to produce the best flowers and fruits. Guava is a tropical plant that can grow in dry climates, but plenty of moisture is also beneficial for the tree, and too much drought can reduce the size and quality of fruits. First, Guava plants need full sun to partial shade to grow, but they cannot tolerate too much heat. 
  • Guava trees in generally planted in full sunshine for best growth and fruit production. Select part of the landscape away from other trees, buildings, structures, and power lines. Remember that Guava trees can grow up to 20 feet in height if not pruned to keep their size. Tropical Guava does not tolerate frost and dies back to the roots in temperatures below -3°C. 

What is the best fertilizer for Guava trees?

  • A fertilizer high in potassium is the best fertilizer for Guava trees to increase fruit production. You should feed Guava trees with liquid fertilizers during the growing season. Guava trees become deficient in iron in alkaline and high pH soil. So, you should fertilize with iron sulfate 1 to 2 times every year.
  • The use of Guava tree fertilizer with a 6-6-6-2 (nitrogen–phosphorus–potassium–magnesium) ratio is recommended. You should spread the fertilizer evenly on the ground for each feeding, start one foot from the stem, then spread to the tree’s drip line. By adding 600 grams of neem cake to the Guava plant, you can produce good quality fruits with increased production. 

Can Guava be grown in pots?

  • You can grow Guava in a wide range of soils, but you should use well-drained, fertile soil to grow in pots. Guava grows best in the soil pH level should be around 4.5 to 7.0. Using a good quality commercial potting soil rich in organic matter is recommended to grow Guava in pots.
  • Select a container at least 18 to 24 inches across and at the same depth. Make sure the pot has proper drainage holes. These adaptable plants make them the best fruit tree candidates for Guava trees in containers.

How deep do Guava roots go?

Guava trees are grown by seed, air layering, and cuttings and typically have a shallow root system with roots within 12 to 18 inches of the soil surface. Guava trees can successfully take root in several different types of soil. Guava trees bred from cuttings, a common method of cultivation, do not take root more than 18 inches deeper than the ground’s surface. 

How do I make my Guava tree bear fruit?

  • Spray your Guava tree shortly before flowering in the spring. Use a 25 percent solution of urea mixed with a wetting agent. Follow the instructions about the amount of wetting agent to add. Combined with the recommended amount of water in a hose and receptacle sprayer. Allow enough time to dry the urea spray before water or rain. Urea has been found to increase the production time of fruits.  
  • Apply fertilizer containing high potash or potassium to increase fruit production and health. Spread 450 grams of 8-3-9-2 fertilizer around the tree’s base in the root zone and work with the trowel or hoe. Guava needs fertilizer three to four times per year. However, you should not fertilize them in late autumn or winter except in many tropical zones. Late-season fertilizing encourages growth and fruit, which is inappropriate in cold climates and can damage the tree.
  • Remove the old wood 3 to 4 inches into the branch and cut before the growth node or swelling on the wood that will form the new growth. Guava will give flowers and fruits from new green twigs that will form where you cut.

How can I increase the sweetness of Guava fruit?

The pulp can change the flavor and taste sweet or sour, depending on the fruit’s type of Guava and ripening. Spray a 5% urea solution on your Guava tree just before flowering with a moisturizing agent. Water the plant when the urea spray is dry. After this, the duration of fruit production will increase. Guava ripens in 2 to 4 months after flowering.

How do you keep a Guava tree small?

  • You can keep the tree small by continuously pruning the top and ends of the tree. Make a round-shaped canopy by keeping the branches around the tree trunk in a similar radius. The Guava tree will work best if placed between 3 and 12 feet tall.
  • Plant Guava in partial shade in desert regions or protect plants from the afternoon sun. Plant Guava in fertilizer-rich, well-drained soil. Guava will grow where the soil pH ranges from 4.5 to 9.4; a neutral pH of 5.0 to 7.0 is best. 

How do you prune a Guava tree?

  • Prune 3 to 4 months after planting to train Guava to the desired shape. If you’re pruning yourself in tree shape, choose the same stem and 3 or 4 lateral branches. Remove all other shoots. Pinch back the tips of the selected side branches when they are 2 to 3 feet.
  • Prune your Guava tree in late winter or early spring each year. Guava fruits on new growth. Annual pruning will boost growth and increase fruits. During the first year, trim the tree to establish a shape and leave a stem and three or four lateral branches for the classic tree shape.
  • Guava should be pruned annually from early to mid-April once the fruit is finished. Pruning ensures that the shrub does not grow into a large tree, making it challenging to collect fruit. Aim to keep the tree about 2 to 2.5 meters high and about 1.5 meters across.

How do I make my Guava fruit bigger?

  • Trim all straight shoots that compete with the main trunk, including suckers that grow on the sides of the bush. 
  • To produce maximum fruit, Guava trees need fertilizers containing nitrogen, phosphorus, potash, and some magnesium. Fertilize 6-6-6-2 3-4 times at the beginning of the growing season and then during development. Potassium-rich fertilizer is the best fertilizer for Guava trees to increase fruit production.
  • In pre-flowering, spray with 0.4% boric acid and 0.3% zinc sulfate to increase yield and fruit size. Spraying copper sulfate at 0.2 to 0.4% increases Guava growth and yield.
  • Remove all the branches that depart from the lower 4 feet of the stem to encourage a higher canopy. Remove all the flowers as soon as they appear so the tree can use its energy in growth. 
  • Trim the Guava tree several times yearly to remove competing straight branches and maintain the tree with a single stem. Prune the tree’s upper branches to open the canopy for sunlight to stimulate further growth. 

Why is my Guava plant not flowering?

  • Guavas growing well indoors may refuse to bloom because they lack an essential component that all blooming Guava requires ultraviolet light. Guava likes a lot of bright, direct sunlight, but if your plant is growing indoors, don’t move it to the window or leave it outside simultaneously. Flowers in north India occur twice a year, i.e., during February and June.
  • Ethephon and Ethephon-urea spray stimulate flower formation in Guava. High concentrations of urea or Ethephon-urea spray in Guava stimulate the production of flowering laterals by defoliation. 

What season do Guavas grow?

  • Guava is harvested throughout the year except in May and June in some parts of the country. However, the peak harvesting periods in north India are August for the rainy season crop, November-December for the winter crop, and March-April for the spring crop. 
  • Guava trees can bloom throughout the year, but spring is the primary season. The fruit usually develops 90 to 150 days after the first blooming. When ripening, the fruit changes from green to yellow and becomes quite soft.

Can you grow Guava indoors?

  • You can be rewarded with fragrant flowers and sweet fruits if the conditions are correct in indoors. Outdoor Guava trees can reach 30 feet, but indoor trees are usually much smaller. 
  • You should grow Guava in a pot filled with any fresh, good-quality potting mix. Make sure there is a good drainage hole under the pot. During the winter months, keep the tree in full sunlight. If possible, you can move the tree to a sunny outdoor area during spring, summer, and autumn. Before the temperature drops below 18°C, you should move the tree indoors. 

How many times Guava gives fruit in a year?

Guava bears fruit all year round. Well-grown and well-maintained trees provide an annual yield ranging from 100 to 150 kg. You should harvest fruits at full maturity but in semi-ripe conditions. Guava in Florida can produce two crops each year; the main crop is during the summer, followed by another small crop in early spring.

What soil do Guava trees like?

  • Guava performs well in different soils but prefers well-drained soils with a pH between 5 and 7. Select a container at least 18 to 24 inches across and at the same depth.
  • Guava grows best in a wide variety of soils as long as the soil has good internal and external drainage. It only means soil that allows water to pass through it easily. Dig a one-foot hole to test for this type of soil and pour a little water into it. It is good soil if the water disappears in just a few minutes. 
  • Guava trees adapt to different soil types, including sand, loam, rock-based soil, and dirt. Soil pH of 5 to 7 is ideal, but plants perform well in high pH soils if supplied with chelated iron content.

How much space do you need for Guava tree?

  • Guava plants can grow 15 to 25 feet long and wide. Give at least 25 feet of space on each side. Although sow varieties are extra short, feel free to plant more than one. The dwarf Guava reaches only four to six feet long and wide, meaning you must allocate only six feet of space between each Guava.
  • You should consider the size of the tree at maturity when doing Guava distance in the garden. Most of the cultivars for home gardens can be planted at a distance of 10 to 15 feet or less.

Why is my Guava tree dropping fruit?

  • The lack of pollination may result from cold or wet weather during blooming or a lack of bees. In addition, if there is a freezing season shortly before the flower buds open, the drop of fruits can be higher. Other adverse weather conditions can also contribute to fruit loss.
  • A Guava tree without fruit can also be the result of the problem of pollination. Apple Guava and Pisidium Guava need partners or will need help from you in the form of hand pollination. Pineapple Guava and Feijoa Sellowiana will be more likely to bear fruit when hand-pollinated.

How do you protect Guava fruit from insects?

  • Using organic pesticides derived from the distillation of Basil and Tea tree leaves containing methyl eugenol is very effective for controlling fruit flies in the Guava orchard, reducing pest attacks and consequently increasing farmers’ income. 
  • The best way to deal with pest attackers is to keep the tree healthy. Provide the best growing conditions with necessary irrigation, proper drainage, and fertilization, and prune out dead or diseased limbs. You should keep the area around the tree free of plant detritus and weeds that can harbor insects.

How is Guava disease treated?

  • The best treatment is you should reduce moisture around your plant, including pruning it and nearby plants to allow for better airflow in all parts of the canopy. Algae thrive at higher relative humidity, so the more the wind can blow, the less likely the infection will survive in the next season. 
  • There is no cure for wilting infections in plants, but good nutrition, including after fruiting, you should give a heavy dose of nitrogen, and protecting the roots from damage can help prevent the disease. 

Do Guavas ripen after picking?

  • Guava is one of the many fruits that ripen after picking. If you pick Guava before it reaches a decent size, it may not have the flavor you’re hoping for when it’s fully ripe.
  • Although experts say that the fruit that ripens from trees tastes better, you do not need to toss out the raw fruit you may have picked. If Guava has reached a certain level of maturity, it will ripen at home. Place the nearly ripe Guava in a paper bag with apples and keep it at room temperature for 24 hours. 

How do you know when to pick Guava?

  • Usually, red or pink Guava is picked when the peel changes from light green to yellow. At room temperature, the fruit is then allowed to ripen further. White Guava is picked up when full-sized and light green from green. 
  • Ripe Guavas are those that have moved from bright green to soft yellow-green. If you don’t find any yellow, you can always buy green Guava and wait for them to ripen. Feel the smell before selecting.


Guava is one of the delicious fruits to consider when planting at home. It has beautiful leaves and fragrant flowers and fruits. Growing Guava with seeds is usually done at home as a fun project. In most cases, the Guava tree that propagated using seeds does not inherit the sweet aroma and produce from the parent Guava. This is why this method is less commonly used for commercial purposes. Guava trees do not reach more than 20 to 30 feet in height, and you can prune them to control their size.
