POST HARVEST TECHNOLOGIES PRACTISED BY INFORMAL FLOWER VENDORS AND FLORISTS WITHIN NAIROBI AND OTHER TOWNS OF KENYA

The local flower market is characterized by informal flower vendors who practice their trade by the roadsides, in municipal markets and on verandas in front of shops within the city centre- read how they minimize post harvest losses. 

image Without doubt, cut flowers are beautiful, but delicate commodities needing careful handling; unfortunately, informal traders do not have proper structures from where to sell their flowers nor government support, hence suffer huge post harvest losses ranging from 20-65%; at worst, 100%.

Informal flower vendors are aware of the nature of the products they sell; they have developed post harvest practices aimed at minimizing loses.

The simplest of this practice is storage of the flowers in a bucket containing water.

WATER: IT’S ROLE IN THE POST HARVEST MANAGEMENT OF FLOWERS.

Water rehydrates, cools, maintains the freshness and extends a flower’s vase life. It has been established that a flower will lose up 5-10% of its water; if not rehydrated soon after harvesting or in storage.

Water loss has the effect of inducing flower wilting; seriously reducing its quality. Thus it is important that this water loss is prevented. Sometimes a flower will wilt despite being placed in water.

This is because the ends have been plugged by bacteria or fungi or air bubbles. Translocation of water by xylem vessels fails; no water flows to the foliage and flower.

Cutting of the stem ends, up to 2.5 to 5 cm long, before storage in water done under clean water removes air bubbles that may have formed in the xylem vessels.

To prevent bacterial and fungal plugging, the water is treated with a few drops of household beach; and changed the water daily. Water uptake can be enhanced by adding a few spoons of sugar to the water.

At times, despite doing the aforementioned, the flowers still wilt. It is likely that such flowers were harvested when immature.

As you buy flowers, develop an eye of identifying immature flowers; nothing can be done to prevent them from wilting sooner than mature flowers.

HOW INFORMAL FLOWER VENDORS COOL THEIR FLOWERS.

Informal vendors ply their trade in the most arduous conditions; they have to chase after their customers as they drive in traffic jams in the evenings, contend with ruthless city ‘askaris’ [policemen employed by the city council], high taxation and operating from the street.

They are aware of the effect of blistering heat on cut flowers and have realized that cooling is essential; not only does it slow senescence, but also enhance the bloom of flowers.

They sell flowers late in the evening when the atmospheric temperatures are low. They use the most rudimentary cooling method-water!

Flowers are stored in buckets containing water treated with ‘Jik’- popular cloth bleach that has antiseptic properties. Very few flower vendors refrigerate their flowers; only those florists who own shops in the city centre or in towns do so.

THE QUALITY: OF FLOWERS TRADED BY INFORMAL FLOWER TRADERS.

Most of these traders buy second grade flowers that cannot be sold in the export market due to insect pests, diseases or too mature heads or immature flowers.

However some of the flower vendors argue that they use the second grade flowers in wreath arrangements and wedding floral arrangements that do not necessarily need flowers that last long.

Those who are contracted to supply offices and households prefer to buy better quality flowers for resale.

In conclusion, vendors need training on proper harvest handling on proper harvest handling and value addition procedures. The government should also provide technical support to these traders.

How to earn millions from 1 acre of passion fruit- Yes it can be done!

Passionfruits Growing Tips In Kenya 

Updated on 25-June 2018

If there is any crop that can unlock your farm's fortunes, and make you scream alleluia, then it is passion fruit. I am saying this because passion fruits have proven to have, a low cost of production, produce high yields per unit area, a ready market, and reasonable prices.

As I write this to you, Kenyan farmers who've taken the cultivation of passion fruits seriously are smiling all the way to the bank. The only complaint they have is, ‘not knowing the secret of growing passion fruit soon enough.'
Trellising passionfruit
Passion fruit can bring you immense profits!


If that statement has made you even slightly interested in passion fruit farming, I know you may have many questions:
  • How much land do I need to start a passion fruit farm?
  • Benefits of growing passion fruit.
  • Profit margins possible from passion fruit farming
  • What inputs do I require to start a passion orchard?
  • Where do I sell harvested mature passion fruits?
  • Where do I get passion fruit seeds/ seedlings for my farm?
  • How do I carry out routine management of my passion fruit orchard?
  • Climatic requirements for passion fruit growing
  • And many more questions.

This issues are many and will need a lot of space to handle. Since I intend to write a comprehensive discussion, this article will be rather long. Find a comfortable chair sit back and relax.

Amount of land you need for Profitable production of passion fruit

Since land is quite an emotive issue in Kenya, let us start addressing the amount of land you need for successful growing of passion fruit.

Here is good news—especially for small landowners:  You don't need to grow passion fruit on tens, hundreds or even thousands of acres of land to earn handsome revenues.

One acre of passion fruit trees--if managed well is sufficient for good returns. But there is a rider to that statement. Depending on the location of the land and target market, your production costs could influence your profitability.

Let me explain what I mean.

Suppose you have one acre of land in Busia (which is approximately 400km from Nairobi), and if your target market in Nairobi, your passion fruit farm may not be as profitable. These low profits are because your production costs will be high, and would eat into your profit.

However, if your target market is the hotels within Busia county, then you are likely to make a kill—even from that one acre of land. All in all, to maximize profit, the further you are from the target market, the larger the area you need.

Before we continue with this discussion on the financial benefits of passion fruit tree farming, here is what other horticultural experts are saying:

HDC continues promoting private sector production of purple passion fruit grafted plants, but demand is still exceeding the ability of nurseries to produce. The good news for growers is that local, Ugandan and export demand is so high that we expect prices to hit Ksh. 90/Kg for quality passion fruit in December.Source: Horticulture development center monthly update November 2004Passion is a prevalent fruit in the domestic market used either as fresh fruit or for processing into juices.Source: Horticulture data 2005-2007 validated reportApril 2008
There is a considerable demand for passion fruit both in the local and export markets, but farmers have been unable to exploit this opportunity.Source: The organic farmer, a magazine for sustainable agriculture in KenyaIssue # 49 June 2009
Significant importers of passion fruit are Uganda (76%) Netherlands (8%), United Arab Emirates (4%), Belgium (3%), United Kingdom (2%) France (2%), and other countries (5%) like Rwanda, Qatar, Norway, Lebanon, Ireland, and Georgia among others...Source: Horticulture validated report 2010
Average yields amount to 10-15 t/ha per year for the purple and 20-25 t/ha per year for the yellow passion fruit. Much higher yields are possible; farmers have reported returns as high as 50 t/ha per year for purple passion fruit in Kenya.Source: www.infornet-biovision.org
Reports indicate that the demand for Kenyan passion fruit in Dubai is high because it is considered natural and high quality.

Let us consider the next important factor for passion fruit production.

The benefits of growing passion fruit.

  • You won't be worried of the market for your product. You have a ready market.
  • A passion fruit farm is easy to manage; the only backbreaking job is during transplanting. Once that is over, the maintenance job is easy like drinking water.
  • Low input cost, high returns. Passionfruit farming is the only type of agriculture where you'll have the opportunity to earn 400% or more profit.
  • You have the opportunity to intercrop the plant with other crops, to maximize your farm's revenue.
  • Three year-long harvest period. You are sure of earning a steady income throughout the period.
  • Even small farms can produce huge profits.

Climatic Requirements For Passion Fruit Growing

The passion planting zone depends on the variety of the passion fruit. The yellow passion can grow at an altitude of 0-1500 m above sea level and is tolerant to drought and fusarium wilt. On the other hand, purple passion fruit prefers cool areas; therefore an altitude of 1200 m-1500m above sea level is best.
   Both varieties prefer well-drained soils and can't withstand water logging.


Feasibility of growing passion fruit in Kenya.

Anyone would be mad—including you and me—if they I ventured into without considering the financial benefits of passion fruit production. For passion farming to be of interest, its production cost MUST be lower than the expected revenue. To arrive at that conclusion, you have to consider three things: the passion fruit's market demand, expected yield per acre, and its cost of production.
The market demand for passion fruit
Let me assure you the selling price of passion fruit is extremely good.

When it comes to demand, the local market and export market are begging passion fruit farmers to supply more fruits to them. They can't find sufficient passion fruits to satisfy their appetite. If you are an entrepreneurial farmer—like me, that is sweet news. When other farmers growing other crops lament, "We have no market for our products, you will be smiling all the way to the bank."

To be satisfied that the demand is HIGH, I did a ‘little' experiment. I walked to city market in Nairobi to find out the price of a kilogram of passion fruits in Kenya. The amount the greengrocer gave me was a shocker. One passion fruit sold for KSH 15! I visited more vendors to be sure of the average selling price. Each passion fruit seller was trading at the cost of 15 shillings per fruit— imagine such astronomical prices. At that price, one kilo of passion in Kenya goes for over 200 shillings!

Why such high prices?

The current prices of passion fruits as so good because the current demand for passion fruits exceeds supply. There are too many buyers chasing after too little passion fruits. Why not take advantage of the high prices and start production immediately?

Another reason I suppose for the passion fruit high prices is the rise in the demand for fresh juices. More and more people are now more aware of the health benefits of fresh passion fruit juice, passion fruit leaves, and the negative impact of synthetic extracts. 

This change of consumer preferences has made manufacturers like Coca-Cola, Delmonte, Kevian juices venture into processing passion fruit juices, mango juice, apple juice, grape juice and other fruit juices.

The math behind passion fruit millions

The passion fruit is a vining plant. What this means is one single plant can grow to a length of over 20 meters. One single plant can yield up to 23 kilos of fruit. With that understanding, we are now ready for the math.


  • I acre is approximately 4000m2
  • The recommended spacing of passion fruit is 2 meters X 3 meters.
  • That means, one plant will need 6  square meters to grow well.
  • To find the number of plants per acre, you divide 4,000 by 6=666 plants.
  • At the spacing of 2 meters by 3 meters, one plant can yield up to 23 kg of fruit per season.
  • At such high production levels per plant, you'll get up to 15 tons per acre of fruit.
  • If one kg sells at a conservative price of KSH 80, you will make sales of KSH1,200,000/=
  • If you factor in ALL the costs of production at KSH 480,000/=, you will make a net profit of KSH 720,000/=

The above mathematics is not a result of guesswork. Peter Mwirigi and others did research titled; Agronomic Management of Yellow Passion Fruit Among Farmers in Mbeere Sub-county, Kenya—they found out that passion fruit has higher returns than maize beans, tomatoes, and cabbage. You can read that research here for yourself.

Another way, to maximize on the returns of your passion farmland, is to intercrop the passion fruit with the various crops. Suitable crops for intercropping are; potatoes, beetroots, Swiss chard, carrots, spinach, strawberries, eggplants, pepper, onions, leek and head lettuce. Intercropping will make you get returns from multiple crops, something that is very good!

That's not all.

Passionfruit profits become sweeter in the subsequent seasons because the plant can live up to 3 years without planting the orchard afresh. In following seasons, production costs reduce, thus increasing the possibilities of higher returns.

What you need to start a passion fruit farm.


  • Grafted Purple passion seedlings.
  • Farmyard manure
  • Conduct a soil test
  • Depending on the results of the trial, you will need inorganic fertilizers like DAP, CAN, Multi K prills, MAP, NPK, etc.
  • Plant hormones to initiate flowering and to regulate growth
  • Foliar feeds to spur the different cycles of plant growth to maximize returns.
  • Fungicides to manage diseases.

Where can I sell mature passion fruits profitably?

To get maximum returns for your passion fruit produce, you'll need a little marketing creativity. This creativity will involve avoiding selling the fruits in the local county government markets. Instead, you'll need to sell them to premium customers like supermarkets, high-end hotels, and exporters. Since these will be your target market, you need to have clean fruits, free of bugs and deformities.

There are many exporting companies that you can approach before starting your farm.
For example, Lagran group contracts farmers to grow passion fruit, Hass avocado, rosemary and other vegetables. 

Where to buy passion fruit seeds/ seedlings

I am sorry to break your heart. As we speak, in Kenya no seed companies are selling certified passion fruit seeds. The reason for this could be that the demand of the seeds is too low to persuade seed companies to start producing accredited passion fruit seeds.

So how do you get the seeds to establish your passion fruit orchard despite this limitation?

Check out our website in future for more details on this.

Although no seed companies are selling passion seeds, some nurseries have passion seedlings for sale. However, you can be too sure of the quality of those seedlings as the incubators are not certified. Unfortunately, you have to rely on their word—you can't be too sure that they've raised the seedlings correctly. That's why in the next one week I will finish writing on how to grow your seedlings. Keep checking this blog for details.

How do carry out routine management of my passion fruit orchard?

Passionfruit vines and fruits are susceptible to various diseases and pests that may prevent your success. Therefore, to avoid spending much money and time on managing diseases and pests, you have to start your orchard right. If you intend to grow purple passion fruit, establish your orchard with grafted purple passion seedlings whose rootstock is on yellow passion fruit.

Manage diseases and pests promptly. Since management of a passion fruit orchard is an extensive topic, keep checking this blog for a detailed blog post.
