Passion Fruit Growing Stages

Before planting them in your garden or pots, you should understand their growing stages. It is important because the needs of each stage will be different. Generally speaking, passion fruits go through four stages of growth before finally producing fruit. Find all the details below!

Passion Fruit Growing Stages

1. Producing Seeds

As with fruit plants in general, passion fruit vines also produce seeds. These seeds are the future new plants when the existing one dies. Moreover, you can take these seeds from the fruit.

Nonetheless, most people prefer to buy the prepared ones in the local nursery. Choose young seeds because the probability of growing is higher than those older than 3 months.

Since they are covered with a thick coat, it is better to soak them in the water for 24-48 hours. This method will soften the coating, making it easier for your seeds to absorb nutrients and water from the soil. Usually, it takes 15-21 days until the seeds germinate.

2. Seedlings

After the germination process is complete, they will enter the seedlings phase. Basically, they are the new plants you will transplant into a pot to grow. The next step is to provide the growing conditions they need. Generally, it takes around four months for the seedlings to be fully established before transferring into fields, gardens, or larger pots.

3. Active Period (Juvenile)

In this stage, your plant will start to flourish. The leaves are growing, while the roots begin to develop further. You may need to introduce them to supports, such as a trellis, so they can climb on it.

In addition, weed and pest control should be applied in this critical phase. You may not see them entering the maturity stage if they get into trouble. In addition, the active period will last about eight months after moving the seedling to the fields.

4. Maturation

Your passion fruit vines are considered mature at 12-13 months after planting. The stage of maturation consists of two critical phases: flowering and fruiting. Flowering commonly lasts for 3-4 years from its maturation. During this process, old blooms will turn into fruits while the vines will continue to produce new flowers.

Like flowering, fruiting will also last until the 5th year, when harvests finally decrease. Then, in the 6th year, the passion fruit vines will stop fruiting. At this point, you can cut them to grow new plants.

Where Does Passion Fruit Grow Best?

The best place to ensure they thrive is an area with at least 8 hours of sun exposure and fertile, well-drained soil. Regarding the soil types, you can choose sandy loam that allows fast draining. Hence, preventing the roots from rotting.

In addition to that, these fruiting plants favor slightly acidic to neutral pH of around 6.5 to 7.0. Soil that is too alkaline or acidic can reduce nutrient availability in the soil. Thus, slowing the growth of this tropical fruit. You can add coffee grounds to increase the acidity in case your soil is alkaline.

Meanwhile, fertilization will provide additional nutrients for your passionfruit vines. However, this chapter will further explain in other sections.

Growing Passion Fruit in Pots and Containers

Growing passion fruits in pots is pretty simple and easy. However, ensure you live in a warm area as it can only stand the cold of the US hardiness zone 6.

Growing Passion Fruit in Pots and Containers

Let’s look at how to grow passion fruit in pots!

  • Choose the growing site. It is crucial to make sure the passionfruit vines thrive. Prepare an area with 8 hours of sun exposure and fertile soil. Make sure the ground is loose to allow better air circulation for the roots.
  • Next, pick pots with drainage holes. You don’t want the roots of your passionfruit vines to rot, do you? So, make sure the containers have holes at the base. Also, choose one with the size of 3.5 gallons to provide adequate space for growth.
  • After that, prepare the seeds. You can take them from passion fruits or buy the dry ones at a local nursery. Choose the fresh ones as the older seeds lower the chance of seedlings.
  • If you wish to remove the fruit seeds, you must dry them first. Rinse them in warm water to eliminate the attached pulps. Then, dry the seeds with a dry cloth or towel.
  • Then, plant them in a seed tray. But before that, fill the space with potting soil. Put one seed on it, and press up to ⅛ of the seed covered in soil. And close the try with lids.
  • Put the tray in the area with bright indirect light. Check on it every 2-3 days. Water them whenever the soil dries by spraying them with water. Usually, germination takes 10-20 days after planting.
  • Once you notice green seedlings, you can remove the lids. Continue the treatments until other leaves grow. This time, you must move the seedlings to a new pot. Choose the 4-inch plant container to allow growth. Don’t get the big one! It can trigger root rot since the water sits too long in the pot.
  • After 4 months, or the seedlings reach 8 inches in height, you can transfer them to a bigger pot.
  • At this stage, you can install support, such as mini trellis to train the vines climbing on it.
  • The maturation will take another 8 months. When your passion fruit vines reach 12-13 months, they will start bearing fruits. 

Watering Passion Fruits in Pots

One of the most important things to support its growth is watering. Passion fruits are heavy feeders. They need regular watering, at least a few times per week. It will be more intense when they approach maturity and fruiting stages.

Furthermore, the watering schedule also highly depends on the season. You can increase the frequency during the hot summer months to prevent dehydration. Lack of water can result in fruit droppings before they mature. However, you must not overwater the soil as the roots are susceptible to rot.

Besides, too much water can drown them, lowering the oxygen and leading to death. Considering this issue, drainage holes in pots are of crucial importance. They will allow water to flow through easily from the container. Thus, it doesn’t trap in the soil for too long.

Best Fertilizer for Passion Fruit

Nitrogen-rich fertilizers are the best to boost foliage growth. Unfortunately, you must not add them to your passion fruit. As fruit-bearing plants, such fertilizers will actually inhibit fruiting. Your plants may end up producing more leaves than fruits.

So, you can choose natural fertilizers like compost. The compost can be made from a mixture of manure and vegetable waste. It is also possible to add a coffee ground to lower the soil pH if it is alkaline. Other alternatives are granulated NPK fertilizers in a ratio of 10-30-10 or 12-24-12. The phosphorus in the fertilizer will help encourage flowers and fruits to grow.

Furthermore, you can start fertilizing the fruits in spring and summer. Don’t skip fertilization because a nutrient deficiency can harm your plants. You will notice yellow vines and lighter new growth when they crave more foods.

Best Trellis for Passion Fruit

As they mature, your passion fruit vines need a trellis to support their structure. But before that, you must know the best types of trellis that will provide ideal support for the vines.

The most popular one is the vertical trellis. It is easy to install. Besides, it is also the cheapest option one can adopt. In addition, spraying pests or weed control is more accessible, thanks to the open structure design.

Another alternative is frame trellis. This is an excellent option for those who have a bit of land but want to keep it looking neat. The shape resembles the letter A, where the vines will climb on the roof. Thus, providing shade for the plants underneath the structure. Such a design also improves yields due to the dense canopy.

Problems and Diseases

Despite being relatively easy to grow, passionfruit vines are not free from pests, diseases, and other evolving issues. Lack of proper maintenance is the main factor that causes these problems to arise.

Problems with Growing Passion Fruits

The following issues regarding passion fruit growth are generally caused by not understanding how to take care of them. So, let’s identify them one by one so that you can provide the best preventive measures.

Why are your passion fruit leaves turning yellow and falling off?

Lack of nutrients and water are the causes of yellow leaves. A deficiency of nitrogen, sulfur, potassium, magnesium, iron and other minerals will result in yellow leaf veins. In some cases, too many minerals also trigger yellow foliage. Moreover, dehydration can cause your vines to wither before turning yellow.

Why is your passion fruit not fruiting?

Lousy pollination may be the culprit behind this. To bear fruit, the flowers must be pollinated by bees. When the weather is extreme, when there is a sudden change of temperatures, bees refuse to wander around gardens. Another reason is overfertilization. It can also lead to fertilizer burn that is detrimental to the roots.

What kills passion fruit vines?

Passion fruits are not resistant to diseases. One of the most common infections is Phytophthora root rot and stem canker. It usually occurs when the soil is moist due to poor drainage or constant rain. Damp soil also triggers Phytophthora blight on the leaves and fruits.

Why is your passion fruit falling off before they are ripe?

Generally, such an issue happens only if they lack water and have nutritional deficiencies. Other external factors, like bad weather, pest infestation, and poor pollination, may also influence the dropping.

Diseases Growing Passion Fruits

To complete the list of issues above, we include some common diseases you may encounter when planting passion fruit vines in pots. Most of them are caused by bacterial infections.

  • Brown Spot: It is caused by Alternaria passiflorae, which infects the leaves, twigs, and fruit of passionfruit vines. The characteristics that appear are brownish-red spots on the infected part. The size can reach 2 cm when the cell vines grow in high humidity and temperature areas.
  • Septoria Spot: Similar to the brown spot, the Septoria spot attacks the foliage of passionfruit vines. However, it doesn’t infect the fruits but the flowers. The infected parts will show necrotic light brown marks. Moreover, your vines will be prone to this disease when you live in an area with constant rain.
  • Root and Crown Rot: This disease is caused by Phytophthora and most commonly affects passionfruit vines. It infects both the young and mature plants on the roots. Symptoms that appear include wilting, leaf fall, and eventually death. Sometimes, the twigs also show a blackish-brown color, like burning.
  • Fusarium Wilt: Unlike other diseases mentioned, this one is caused by a fungal called Fusarium oxysporum. At first, the leaves of your plant will change color to light green and then wither. Then in no time, they finally suddenly died as the disease spread.

Final Thoughts

It is possible to grow passion fruit in pots. But remember to provide a trellis once they mature to support the structure. As these vines are prone to diseases, proper care is extremely crucial. Especially if you live in an area with high humidity and constant rain.
