Mangosteen "Mesta" Seeds - 3 Pack


Garcinia Mangostana

The Mangosteen fruit is highly valued for its juicy, delicate texture and slightly astringent flavour! Mangosteen is referred to as the Queen of Fruits. We are so excited to bring you directly from our orchard overseas the ultra-rare variety of Mangosteen - Mesta. Mesta is not only deliciously sweet, but the fruit is also larger with more flesh and almost seedless. Mesta is also an early fruiting variety and extremely popular in Malaysia.

It is extremely hard to source reliable seeds from Mesta Mangosteen for propagation purposes due to its fruit being close to seedless, but fortunately we have been able to source a very limited amount from our nursery overseas and now it's available for you.

At first glance, you may find it difficult to differentiate between both types but upon closer inspection, you will find that Mesta Mangosteen does not have true seeds. The false, or adventitious embryo grows into a fruit, due to an absence of sexual fertilization. The fruit of Mesta Mangosteen is developed from the cell wall of a female flower and the lack of sexual reproduction makes its genes unchanged over countless generations.

Mesta has more branches, and is a much smaller plant compared to the normal mangosteen and fully matures at 4 years of age. In ideal conditions and with the right climate, the Mangosteen Mesta fruit around 4 years - though in NZ, it will likely take 5+ years. This is significantly shorter than the typical mangosteen variety.

How to Get Started?

All seeds need water, oxygen, and proper temperature in order to germinate. Some seeds require proper light also. Some germinate better in full light while others require darkness to germinate. When a seed is exposed to proper conditions, water and oxygen are taken in through the seed coat. The ideal soil temperature for germinating seeds is between 20 and 30 degrees Celsius. Once the seeds germinate, the soil temperature needs to be cooler than the optimum germination temperature to support the growth of seedlings. 

Mangosteen seeds are small seeds and protected in their own cleaned fiber. The seeds need to be warm up under the sun or under the light for 15-30 minutes until it is at room temperature. The seeds then soaked in a warm water for up to 12 hours. They should be planted flat or at an angle and fully covered with a good soil mix. The mix needs to be well drained, with at least 50% perlite or coarse sand, and should be maintained uniformly moist but not waterlogged. Coco peat is another option for a good seed sowing media. We also found germinating the seeds with lightly soaked sphagnum moss in a zip lock bag to be successful. Alternatively use a high-quality seed raising mix and add some light sand or topsoil. Use water misting to keep the soil moist. Another method is by placing seeds in seed growing sponges and keep them in a resealable bag and spray with water often. It may take up to 90 days for seeds to germinate, some species of plant may take even longer. NOTE - Mangosteen seeds take a lot longer to germinate than other seeds and 6-12+ months is common. 

Using a heat mat will certainly increase seed germination rates but not necessary. Sometimes seeds turn to dormancy during the colder season and will sprout as soon as the first signs of spring occur. Always soak your seeds for up to 24 hours prior to planting. Apply some light fungicide solution on the seeds, pat them dry prior to sowing to avoid mould growing on seeds. Do not soak the seeds for more than 24 hours for the soft shell or skinned on seeds whilst soaking for 48 hours for a hard-shell seed is quite acceptable. Small seeds usually germinate better with some light whilst bigger seeds need to be slightly above the surface. Do not sow seeds too deep unless its hard-shelled seed. If the seeds are sown too deep, they need extra energy to get to the surface for light.

Once germination occurs, gives plenty of light, remove any cover and never miss any watering so the top of soil is always moist. If the seedlings receive plenty of heat and sun, they may need watering once a day or every second day. Usually, seedlings can be transferred to another size pot once there are 2 leaves showing.  The ideal size of pot is three times the size of root ball. Prepare a good quality potting mix in advance before repotting the plant. The next repotting should only be after 6-8 months once the seedlings are more established. Try not to transplant any subtropical fruit trees directly into the ground until they pass their first winter at the minimum. 

Mangosteen needs a warm climate and is not suitable for outdoor growing in the South Island. It thrives in all sorts of soils but prefers sandy well-draining soil. Partial shade is what they need, young seedlings will not survive direct sun light. Keeping the plant warm between 21-29 degrees Celsius is ideal, or they are happy in a greenhouse or growing indoors at room temperature. Plants will grow to the size of the pot, and minimal watering and fertilizing is required around winter and more often around the spring till the end of summer. Subtropical plants usually prefer well composted animal manure as fertiliser. However, an alternate feed with general fertiliser is acceptable and some seaweed or worm juice every 2 to 4 weeks during growth time will see them growing strong and healthy. Never used sheep pellets for pot plants - especially for subtropical fruit plants.

Keep subtropical plants in the warmest area indoors or in a greenhouse/polytunnel for their first 1-2 years and slowly introduce to a shaded outdoor area when the weather is good. Keep young seedlings protected from frost and strong wind. 

NOTE that Mangosteen seedlings might need to stay in a planter bag or pot for a very long time at least until they have matured enough to fruit. If you have a greenhouse, it could be planted permanently in the ground when the seedling is big enough for transplanting.

Good luck and happy growing!
