Growing tropicals from seeds.

From Kristi the Wizard of Rose: I grow many plants from seeds, both for my personal collection, and for TopTropicals. I receive many questions from customers who want to grow tropical plants from seeds. Some of them live in colder climates and try to extend growing season of their tropical collections by starting new varieties early in the year from seeds. These are a few tips that may be helpful.

Q: What do I need to do to speed up germination process?

A: Many factors affect germination. Considering you get fresh seeds (for example from TopTropicals) and Mother Nature gives them a good kick start, there are a few things that may speed up germination:

1. Scarification. Large seeds with a hard outer shell can be slightly sanded down just enough for moisture to get inside to wake up the seed during the pre-soaking. Be careful not to damage the seed. See example of Lotus seed scarification.
2. Pre-soaking. We recommend pre-soaking most of the seeds for only a few hours (3-8 depending on species. Some seeds are very sensitive to moisture and may start rotting if stay wet without air circulation. Small seeds, especially tiny ones like dust, should not be soaked.
3. SUNSHINE-S treatment. Adding a few drops of SUNSHINE-S booster when pre-soaking seeds increases their germination rate 3-5 times.
4. Temperature. Warm temperatures help germination. If grown indoors, put seeds containers or trays in the warmest spot of your house; you may use heat pads. Outdoors, putting them in full sun helps a lot, just don't let soil to dry out.

   Use only special porous seed germination mix to provide air circulation and prevent seeds from rotting.

   Q: Should I keep seeds in refrigerator before planting?

   A: Do not refrigerate tropical seeds. Stratification (treatment with cold) works only for temperate species, and some subtropical (like non-tropical Magnolias)

   Q: How do you grow eucalyptus from seeds? I tried a few times with no success.

   A: The secret of germinating tiny seeds like eucalyptus is - to sow them on top of the moist soil surface (soil must be very fine and soft), without covering. Keep container covered with clear plastic, in bright light. Use spray bottle to keep surface moist but not soggy. I have a customer who germinates eucalyptus seeds using an old fish tank, covered with a glass. Perfect environment - bright light and moist all the time.

How to make a Mango tree bloom and fruit

Mango trees are especially beautiful during spring time when they flush out multi-color new leaves! But you want your mango be not only beautiful but fruitful as well. Here are some tips:

1) Fertilize Mango tree with a balanced slow release fertilizer starting March. Use 1 tsp of granulated fertilizer per 1 gal of soil, or a handful or two for an in-ground tree. You may add one application of foliar spray of a water-soluble bloom booster fertilizer (the one for Roses or Azaleas will work). This will give your tree a good macro-nutrient kick-start.

2) Spray entire tree with SUNSHINE-Superfood solution. This will provide all necessary micro-elements and keep the plant healthy and strong throughout the season. Repeat treatment once a month until harvest time.

3) For sweeter fruit, apply SUNSHINE-Honey solution several times:
- early spring before flowering
- at setting buds
- right at the beginning of setting fruit
- after harvesting, to provide the tree with all good micro-nutrients before resting season.

What you need for successful growing Adeniums

1) Adenium plants - from TopTropicals Endless selection of Adeniums. We have double flower, red, purple, yellow and even black flowers!
2) A small pot with excellent drainage is a must. Position the plant in a pot, size of root system.
3) Adenium soil mix. TopTropicals Adenium Soilless Mix. Use only well-drained soil.
4) Lots of light. Adeniums need lots of light for heavy flowering. However from our own experience, in super hot climates, they look healthier in filtered bright light. After initial planting, once the plant is established and starts growing new leaves (may take a few weeks), gradually move it into brighter light.
5) Little water. Adeniums like a neutral to hard water. Acidic water tends to sour the soil too fast and may cause root rot. Water plants preferably in the early morning, and allow them to drink up throughout the day. Watering can be done daily to every few days. Do not water again until soil dries on surface. Never allow your plants to sit in a saucer of water, but don't let them to dry out too often - this causes adeniums to go into early dormancy. Adeniums do not like both over-watering or drying-out.
6) Fertilizer. To make your plant develop a large swollen base/trunk, you'll need a good quality fertilizer. Use slow-release granulated fertilizer for overall plant health, and liquid water soluble fertilizer for swelling up trunks that is also used to increase flowering. It shouldn't be too high in nitrogen, the middle number should be the highest (similar to 10-50-10). Never apply fertilizer directly on roots and do not liquid feed when a plant is thirsty: always water first slightly to avoid root burn and leaf drop. Do not wet leaves.
7) SuperFood micro-elements. Besides macro-nutrients provided by fertilizer, Adenium needs micro-elements for balanced development of root system and especially caudex: Sunshine-SuperFood.
8) SUNSHINE-BC. Spray leaves with SUNSHINE-BC once a month to encourage young growth, profuse flowering and large caudex.
9) Growing caudex. There is a secret how to create a large swollen caudex: raise the plant a bit every time you re-pot it, so that the upper part of roots will be a little exposed. The plant will form more roots that will go down.

Avocado, Lychee and Mango setting fruit... give them some FOOD!

Q: Do I need to fertilize tropical fruit when they set fruit?

A: It is traditionally believed that mango and other tropical fruit shouldn't be fertilized during fruiting period. It is true to an extent: you don't want fruit to burst from fast excessive growing. Instead, try to feed fruit trees wisely, because they still need proper nutrition to produce flowers and fruit.
Our spring specials of Lychee, Avocado and Mango are full of buds and some already set tiny fruit (see examples on the photo). Here is the feeding plan for these plants once you receive your mail order:

1. Once received the plant, pot it into container size of the root ball and let establish for couple weeks. Use SUNSHINE-E to help the plant recover from shipping stress and establish root system.
2. Apply SUNSHINE-Honey right before flowering, and next time at setting fruit, to provide sweeter and bigger fruit, eliminate fruit cracks and help resist fungus and other fruit diseases.
3. Use balanced granulated fertilizer, 1 tsp per each gallon of soil. Apply once a month during Spring-Summer season. This gives the plant balanced macro-elements (NPK) necessary for overall plant health. Do not use on fruit trees fertilizers with high Nitrogen content.
4. Apply SUNSHINE SuperFood micro-element booster to keep fruit trees vigorous, develop strong root system and avoid deficiencies.
5. In case of signs of chlorosis (yellowing leaves with darker veins), give the tree SUNSHINE-GreenLeaf and watch the leaves turning green quickly.

SUNSHINE boosters for recovering plants after shipping

Q: I live in Garden City, NJ and have a sun room with a tropical plant collection that I keep at about 40-45 degrees in winter. I used Sunshine booster during winter for my plant collection and results were amazing! I haven't lost a single plant. Now I see you have more products and I am planning to purchase more plants, how should I use Sunshine boosters to help plants recover after shipping?

A: Spray SUNSHINE-E solution right after receiving a plant from shipping. It will boost up the plant and make it 50-60% stronger and easier to recover after shipping stress. After that, apply SUNSHINE-SuperFood microelement booster to provide everything necessary for the plant to grow vigorously and happily. SUNSHINE-E is indeed a wonderful plant stimulant and stress reliever, although it is not a "magic-cure-all" medicine where one can't find its active ingredient. The hormone (epibrassinolide) is well-known and used in different countries along with other hormones for promote growth, fruiting, blooming, rooting, etc. One of the most amazing properties of SUNSHINE is that it works in extremely low dozes. Only a few drops will be enough to make a solution in distilled water, to treat a large size plant. If you want to try it out, one 5 ml bottle will last for several applications. Large bottles of SUNSHINE 50 ml and 100 ml - great for small and big gardens. It is a good idea to start bi-weekly applications to improve your plants tolerance to Summer heat, drought and improve disease resistance. The formula works through plant metabolism within 2-4 days, repeat application not sooner than in one week. After application of SUNSHINE-E, don't forget to boost your plants with SUNSHINE-SuperFood .

Fruitful Fruit and SuperFood...

Q: I have a large fruit garden here in Florida with many mango trees, avocadoes, guavas, and other tropical fruit. Last year hurricane Irma and flooding killed a few avocado trees, but mangos and guavas survived OK, but the sad part is, very few flowers this year and almost no fruit setting. I noticed on your website your Superfood and Sunshine-Honey boosters that supposedly help fruiting? But I am afraid it is too late now as your instructions say first application must be in early Spring? I wish I discovered earlier that my trees wouldn't want to fruit this year...

A: First of all, it is never late to give the food! You may start applications of SUNSHINE products at any time of the year. The best results will be achieved once you treat your plants on regular basis throughout the whole year cycle of metabolism.
Couple weeks ago we started harvesting our 2 guava trees. These two are the same variety (Variegated Honeymoon), planted within 20 ft from each other and growing in the same conditions. The only difference was, one was treated with SUNSHINE-Honey and SUNSHINE-SuperFood, and another one didn't get any treats in order to have a control plant.
Results are very interesting, see the picture. Both trees were heavily covered with fruit. However the one with treatments developed fruit that is much larger, much sweeter and juicier, and the most interestingly - with less seeds, almost no seeds!
To answer your question: yes, you can start feeding your fruit trees right now. It is still a Springtime. Many mango varieties have late season; even early varieties may delay their fruiting if flowering triggered by miscro-elements. Guavas have very long season and most varieties can have multiple crops throughout Summer-Fall.
Here is a simple and affordable feeding schedule to help your fruit garden recover from last year hurricane stress, and establish reliable production:

1. SUNSHINE-E - for boosting metabolism - once a month
2. SUNSHINE-Honey - for bringing sugars to the heart of the tree and boosting fruit sweetness and quality - now and in 2 weeks
3. SUNSHINE-SuperFood - for overall health, recovering from hurricane and fixing root damage from flood - now and every 2 weeks throughout warm season.
4. You may apply regular balanced fertilizer NPK as usual (we apply once a month, a handful per in-ground tree)

Mysterious Night Blooming Cactus - Epiphyllum. How to grow it?

Q: My friend has a huge Queen of the Night Cactus, and the blooms are so gorgeeous! She gave me a cutting but I am not sure how do I plant it? How long will it take till it starts blooming? Is it true that it has only one flower once a year and only at night?

A: Queen of the Night is a very popular and yet mysterious plant. The flowers open once a year after sunset for one night. However the flowering period can last a month or two during the warm season. So each flower lasts only one night, but there will be more flowers to come! In the Nature, Epiphyllum oxypetalum - Queen of the Night - grows on trees in the jungles of Central and South America. It is actually very easy to grow as an indoor plant in colder climates. Here is South Florida we grow them outside in hanging baskets. This is how to start Queen of the Night from a cutting:

1. Put the cutting in a dim, dry place for three days, with no soil and its base exposed to the air, so it will form a callus.
2. Fill a 4-6-inch pot with slightly damp potting soil or succulent mix. Insert the cutting 1 or 2 inches into the soil and tamp the soil around its base.
3. Place the pot where the cutting will get bright light, but no direct sun. Spritz it occasionally with a spray bottle of water to keep the soil only slightly moist. It should root in couple weeks.
4. Keep the plant on an east- or west-facing windowsill where it will receive direct sunlight only in early morning or late afternoon. Water the cactus until water runs out of the pot's drainage holes. Dump the excess out of the pot's saucer immediately, and wait until the surface of the soil is dry to the touch before watering your cactus again.
5. Fertilize once a month from March through October with a balanced plant food, and apply micro-elements once a month for a healthy vigorous growth. Refrain from feeding the plant in December and January.
6. Position the cactus in partial shade under a porch roof or tree, if you decide to move it outdoors during the summer. This plant likes summer humidity!
7. Repot the cactus only once every two years or so, to keep it slightly root bound. Wait until after it flowers in summer, and repot it after it blooms. Prune off any damaged growth at that time as well.
8. Move the plant to a cooler room over the winter months, one that remains dark during the evening hours with temperatures above 45 degrees. Reduce the frequency of watering, waiting until its soil is dry. Resume regular watering in March.

   If grown from cutting, it may take 2-3 years until the plant starts blooming, so if you don't want to wait that long - just get a blooming size plant from our store!

   We only have a few plants... if sold out, add to wish list and we will have more soon!

   

URBAN TROPICAL GARDENING:
10 secrets of successful Container Mango growing on a balcony.

Q: I live in Miami in apartment on a second floor, and I have a balcony with SE exposure. I wonder if I can grow a mango tree in a pot? Will it fruit for me? I recently moved to South Florida and I don't know much about tropical plants; but I tasted real fiberless mangos from someone's garden - it was so delicious and different from those in the grocery store. I wonder if I can have a fruiting tree on my balcony? And if yes, how do I plant and take care of it?

A: Yes, you can! Here is what you need to do:

1. Temperature. You are lucky to live in Tropics, keep it on a balcony year round.
2. Light. Position the pot in a spot with the most sun exposure. Mango trees can take filtered light too, but the less sun, the less fruit you will get.
3. Soil and Container. Use only well drained potting mix. Step up the purchased plant into next size container (3 gal into 7 gal, 7 gal into 15 gal). When transplanting, make sure to keep growth point (where roots meet the trunk) just at the top of the soil. Covering base of the trunk with soil may kill the plant.
4. Water. Water daily during hot season, but only if top of soil gets dry. If it still moist, skip that day. Mangoes (unlike Avocados!) prefer to stay on a dry side.
5. Fertilizer. Use balanced fertilizer once a month, 1 tsp per 1 gal of soil. Do not fertilize during fruiting - this may cause fruit cracks.
6. Microelements. Apply SUNSHINE-Superfood once a month. This will help your mango healthy, vigorous, and resistant to diseases. Use SUNSHINE-Honey to make your fruit sweeter.
7. Insect control. Watch for scales and mealybugs, clean with solution of soapy water + vegetable oil (may need to repeat 2-3 times with 10 days interval), or with systemic insecticide like imidacloprid only as needed (if non-harsh treatment didn't help). Most Flea shampoo for dogs contain that chemical, you may try that shampoo solution.
8. Trimming. Once potted, do not remove leaves that are discolored or have spots until new growth appears. Dark dots on mango leaves, especially in humid climate like Florida, may be signs of fungus. Treat with fungicide according to label, and remove only badly damaged leaves. Trim crown as needed after flowering and fruiting (by Fall). Train into a small tree, and you may remove some lower branches eventually.
9. Flower and fruit. Mangoes are winter bloomers with bunches of tiny flowers coming in thousands. Many of them set fruit (if pollinating insects present). Keep in mind that young trees can only bare a few fruit. Normally a tree will drop excessive fruit and keep only a few that it can manage. To save the young tree some energy, remove fruit if too many and leave only 2-3 for the first year. It will pay you next year with more abundant crop.
10. Variety. Last but not least: Choose the right variety for container culture! Pick from "condo" dwarf varieties such as Icecream, Nam Doc Mai, Carrie, Cogshall, Julie, Fairchild, Pickering, Graham, Mallika, and a few others - check out Mango Chart pdf and full list of our Mango varieties.
