How to feed a Mango tree...
and to grow a Dwarf Mango

How to fertilize a Mango tree

Q: My mango trees that I bought and planted last august now have fruit. I bought 2 types of fertilizer from you and never used it. Should I use your fertilizer now?

A: It is a perfect time now to fertilize your plants as they start active growth. For mango trees, we recommend liquid fertilizer Sunshine Booster - Mango Tango. It is formulated for Mango trees, especially for container grown. It improves quantity and quality of flowers and ability to set fruit, reduces bud-flower-fruit drop. Can be used as often as with every watering. For best results, use in combination with Sunshine Honey and Sunshine Superfood plant supplements. Its scientifically-balanced stable formula is organic Amino-acid based and has NO EDTA chelators to eliminate nutrients lockup; it does not affect crop taste.
Additionally, you may use slow-release granulated fertilizer Mango-Food once a month during hot season only. Dosage: 1 teaspoon per each gal of soil. Water-soluble fertilizers can be also used, however, those are usually EDTA-chelated which is not as efficient as Amono-acid based Sunshine Boosters and may create nutrients build up, especially if overdosed in containers.
For in-ground mango trees, you may use all the above, and slow-release granulated fertilizer can be applied in larger quantities: spread a handful around the drip line.

Remember that only liquid Sunshine Boosters can be applied year around. With other fertilizers, you need to be careful not to overdose, and apply only during hot weather (when night temperatures are steadily above 65F).

How to grow a Dwarf Mango tree

Q: I received the Ice cream mango tree in great condition (thank you for the ingenious packing job) on Wednesday and have planted it in a pot slightly bigger than the root ball. I plan to grow the tree on my front porch, so how big a container should I ultimately use when the tree outgrows this pot? How big a container does it need to fruit? I hope to keep it around 6-7 feet high, if possible. I live in Hawaii.

A: Ice Cream mango is a perfect variety for container culture, and it should be happy in Hawaii. You did everything right. Keep it in this small pot for now and wait until it starts vigorous growth in Summer. Once it starts growing (and you will notice roots growing too, sometimes they try to grow through the holes in the bottom of the pot), then it's time to step up into a bigger container (7-10 gal). Eventually you may use container size as large as 15 gal. Ice cream mango is slow growing and compact, and you will be able to maintain it under 7 ft with very minimal pruning if any.

7 secrets of a Happy Avocado Tree

Q: I purchased an avocado tree from local garden centers three times but every time it dies on me. My neighbor has a nice tree in his yard and it grows beautifuly. I just purchased one online from you and I need to know what I was doing wrong? Are there any secrets how to make an Avocado tree happy? I have a big garden and several mango trees, but no luck with Avocado...

A: Avocado tree is famous for being such a pain to establish. But once it starts growing, it's growing! We will share a few simple tricks how to make it right.

1. Plant high and provide good drainage. Wet feet is number one reason for failing an avocado tree. It doesn't like wet soil and won't tolerate soggy conditions. Plant it in the highest spot of your yard and slightly on a "hill" (3-4" higher than the surrounding ground).
DO NOT plant Avocado tree in low spots or wet spots of your yard. Save those spots for Cannas or Black Sapote or even a Mango if you want a fruit tree there.
2. Use quality soil. Use only well-drained soil with high content of organic matter. You may add compost to existing sandy soil, or add some professional potting mix that contains pine bark and perlite. Remove rocks from the hole if you see any while digging. Dig a big hole and fill it with a good soil; compact the soil in the hole very well before setting the root ball. Reminder: plant the tree high!
3. Water regularly. After planting an Avocado tree in a nice high spot with a good drainage, start watering it... daily! Avocado likes water, although it doesn't like wet feet! Once you figure out this combination, you've got the recipe of success. Water by hand daily for the first week after planting, then twice a week for couple weeks, then once you notice new growth - you may rely on sprinklers, but keep watching the tree and don't let the soil over-dry. It must be slightly moist, but not soggy.
4. Fertilize. For such finicky tree, we suggest mild formulas of fertilizers. Dry fertilizers may burn roots, especially of a young tree. Even smart-release granulated fertilizers should be used very carefully. The best way to feed your young avocado tree - get a complete set of Sunshine Boosters Pro system. It has all necessary elements for all stages of plant development and never burns the roots. Sunshine Boosters Pro can be used with every watering - no need to guess how much and when. Besides, it is a natural fertilizer based on amino acids - exactly what you want to use on your fruit trees and other edibles!
5. Boost immune system of the tree. Apply Sunshine Epi plant hormone every 2 weeks as a foliar spray to boost immune system and metabolism of the tree and protect it from diseases. Epi makes plants (especially young plants) grow twice faster! It also enhances effect of fertilizers by increasing plant metabolism.
6. Do not prune until you see significant growth. The tree is small and can use as many leaves and branches as possible for photosynthesis and healthy metabolism. We suggest to avoid pruning for at least the first year. On the second year your tree most likely will be covered with flowers (assuming you followed fertilizer program). Let it go through the blooming stage and setting fruit; prune in Fall after fruiting is over.
7. Keep number of fruit to minimum for the first crop. Don't let the small tree exhaust itself. Keep just 2-3 fruit to develop. The next year, no need to control fruit quantity, the tree will develop as many as it can support.
P.S. If you got the tree from a mail-order, remember to establish it in a pot before planting in the ground; move gradually from shade to sun. Follow planting instructions.

When plants are ready for a meal?

Q: We have an early Spring here in Florida. All plants in my garden flushing out new leaves and buds opening. Can I start fertilizing? I have Mango, Avocado, Peach trees, many medicinal herbs and flowering shrubs: Angel trumpets, plumerias, bromeliads. I prefer mild organic fertilizers; can you suggest something that is safe for edibles and butterflies?

Q: As a rule of thumb, tropical gardeners start regular fertilizing when the minimum temperatures (at night) go above 65F. Keep in mind that Sunshine Boosters fertilizers can be applied year around because they have mild formulas and used with every watering; during cooler period, you water less frequently, so feeding is reduced accordingly. Another advantage of Sunshine Boosters - they are natural (derived from organic amino acids which is the basics of Life). They are safe for edibles as well as pollinating insects.

Here is the feeding plan for your plants:

The most universal solution for all plants (both potted and in-ground): get a complete set of Sunshine Boosters Pro system: Advantage-Pro for vegetative growth, BloomBoom Pro for flowering stage, and Ca-Support-Pro + Constanta-Pro as necessary daily supplements. You will need all these 4 components for your garden.
Start adding these liquid boosters with every watering according to dozing directions and you will notice amazing growth boost within a week.
Apply Sunshine Epi plant hormone every 2 weeks as a foliar spray to boost immune system and metabolism of plants and protect them from diseases. Epi makes plants (especially young plants and those "waking up" from dormancy) grow twice faster! It also enhances effect of fertilizers by increasing plant metabolism.
After cool winter temperatures, some plants may develop element deficiencies like chlorosis (yellowing leaves). Additional microelement boost can be provided with Sunshine Greenleaf (iron supplement) and Sunshine Superfood (micro-elements).
For additional boosting of flowering and setting fruit, use the following individual boosters:

Sunshine Robusta - for foliage plants and when you need rapid vegetative growth
Sunshine TotalFeed - for Plumerias and other fragrant plants
Sunshine Megaflor - for Brugmansias and other flowering heavy feeders
Sunshine C-Cibus - for improving fruit production and quality
Sunshine Honey - for sweeter fruit (must be applied 4-5 times a year)
6. For young/small plants (seedlings, rooted cuttings) as well as tender tropicals like bromeliads, and orchids - Sunshine Bombino is a perfect choice due to its mild formula.
7. To save money, order complete sets rather than individual boosters; you will be able to safe up to 40%! Sunshine Complete Nutrition System Kits: Combo Kit, and Pro Kit.

If you are a fan of organic gardening, do not use dry fertilizers. While water-soluble and granulated (smart-realease) fertilizers are popular choice in plant nurseries due to their convenience, they are not as safe as liquid boosters because they create salt build-up in soil and have a high risk of overdosing/burning plant roots, especially potted plants, plants at breaking dormancy, at establishing, and at early stages of plant development. Besides, dry fertilizers may affect the taste of your fruit and herbs. See advantages of liquid boosters over dry fertilizers.

When to apply super boost?

Sunshine Boosters: a breakthrough in Winter fertilizing

In the photo: plants are tough survivors. Life can't be stopped even by a brick road!

Q: Just wanted to know best time of day to apply super boost as spray and watering? Only listed to make sure night temp doesn't drop below 65F...

A: As a rule of thumb, plant's needs in fertilizers are very low in the cold season because they consume less nutrients during dormancy. For tropical plants, when minimum temperatures drop below 65F - we stop applications of dry (granulated) fertilizers until spring, to avoid root burn.
Liquid Sunshine Boosters are exceptions from this rule to a certain extent, for 2 reasons:
- they are amino-acid based which means, salts do not build up in the soil, and thus will not burn the roots even with slower plant metabolism.
- concentrations/formulas are mild and designed for as frequent as daily watering

1) When a plant goes into full dormancy (drops leaves and does not show any new growth), you may stop fertilizing with any Macro NPK products (both dry and liquid)

2) If a plant is evergreen and continues growing during the cooler period, and especially if it is a winter bloomer, mild liquid fertilizers can be applied, depending on the stage of plant development.
Robusta and TotalFeed are used for vegetative growth and pre-flower.
Megaflor and C-Cibus are used for winter flowering/ fruiting plants during the bloom stage.

See full list of liquid boosters

3) Micro-elements can be used all year round for all plants that are not dormant (do not drop leaves)

4) Always use Sunshine-Epi as a foliar spray to activate immune system and unlock protective mechanisms, BEFORE applying other boosters. It is especially important during Fall-Winter for improving cold tolerance and disease resistance.

5) Always apply foliar spray and/or drench the soil with solutions in morning hours so the plant has time to process the nutrients during daylight when metabolism is the most active.

6) Avoid any dry fertilizers during winter

Saving Fallen Papaya Tree

Q: Hope there is help for my beautiful amazing papaya tree! There where a loooooooot of fruits on it, but it broke! First of all, it was leaning and friends tried to straight my beautiful tree. What can I do? Will it get fruits again?

A: A couple months ago we also had a Papaya tree loaded with fruit that fell down (see photos). It was heart-breaking. We secured it and it continued growing for a couple of weeks but unfortunately, at the end the tree still died, leaving us a million fruit. The Papaya tree has a very sensitive root system and is hard to re-establish once the roots are damaged.
However, if it just has a broken top, it has a good chance to grow back from the side shoots.
Of course, remove all the fruit so they don't take energy from the recovering tree.
When a tree is loaded with fruit, it is important to provide support for heavy branches and for the trunk if needed. Always support the fruiting tree to prevent from possible falling BEFORE it starts leaning down and may become broken by even a light wind.
In the photo, you can see how we fixed boards around, but it was already after the tree fell. Unfortunately, it was too late since the roots got damaged. Always need to stake the tree up before the branches get too heavy!

Only local pick up from our Garden Center
Hurry up, while supply lasts!

Trimming Mussaenda bush

Q: My wife and I bought a Dona Evangelina from you this year. It thriving and has grown to 6-8 ft. It has become top-heavy and in wind, it falls over. Main stems have split twice but still continues to grow. I usually prune Dona Luz back to 3-4 ft and am wondering how much you would advise me to lop off your plant. Any advise will be appreciated.

A: Mussaendas, indeed, have very fragile stems that break often, especially in Florida wind storms. The good news is, these plants grow vigorously once established.
You did a good job trying to tie together the split stems and in fact, cracks do grow back together as long as the dressing is tight. Try to use green tape or even electric tape to tighten the broken spot.
However, do such repairs only if it is critical for a plant. When possible, simply cut off the broken branch and give the plant a chance to grow a new stronger branch. You may trim the bush pretty short. Mussaendas respond well to pruning which promotes more side growth and makes the plant bushier.
Keep in mind that during cold weather, Mussaenda may drop all leaves and go into dormancy until spring.

Hardy Plumeria Pudica

Q: I have ordered plumeria pudica from you in March and it is thriving really well here in Rancho Cordova, California. The current temperatures are ranging from 68 to 32 degrees Fahrenheit. My USDA zone is 9b. Does this plumeria pudica survive outside with temperatures dropping in coming winter in CA?

A: From our experience, Plumeria pudica is pretty cold hardy and takes some cold spells in spite of being a tropical species.
Our trees (well-established) took a few hours of freeze with no significant damage.
Potted plants are less hardy than in-ground plants. However, their advantage is, they are easy to move indoors or inside warmer place like garage, etc. If the temperature stays borderline around 32F for a few hours, the plant should be safe as long as warm day temperatures follow a cold night. For longer periods of cold, move the plant inside.
Make sure do not overwater and keep Plumeria on a dry side during winter, since cold and wet is a bad combination and may cause root problems.
Above is the picture of Plumeria pudica tree growing in Cape Coral, FL where low temperatures in winter sometimes go down to upper 20's for a few hours.

To improve cold hardiness of Plumerias and other tropical plants, use SUNSHINE-Epi-T for plant thermal protection and immune system boost.
Make sure to fertilize plants on regular basis to keep them strong and vigorous. The stronger and bigger the plant, the hardier it is!

Fragrant Gold Leaf Orchid Vine

By Onika Amell, tropical plant specialist

Q: I am absolutely thrilled to see you have this vine. I've tried for years to get this plant! It is so, so rare. It just seemed impossible to find in this country. How do I make it thrive? I am ordering two.

A: We are happy to confirm that indeed we do have this rare vine!
Bauhinia aureifolia - Gold Leaf Orchid Vine - was discovered in Thailand in 1983. It is endemic to Pattani, Narathiwat, and Yala in Southern Thailand. Danish botanist Kai Larsen named this plant and hailed it as one of the rarest plant species of the world when it was discovered in the eighties.
The Thai people call this vine Bai Mai Si Thong. It is a beautiful climber with large, bi-loped leaves (7 inches or more!) and good branching.
Young leaves are a stunning burnt orange to terracotta color for about a week and as they reach full size, they turn green over a couple of days. This is a very rare color for Bauhinia. It produces leaves all the time and this means this vine is always full of beautiful color. With its golden leaves, it sure is reminiscent of Autumn.
This vine blooms from May to November. It bears bunches of small flowers that are delicately fragrant in the evenings. The cultivated plants range flower color from pure white to purple and pink, while the wild ones have often white petals with pinkish patches.
Bauhinia aureifolia needs well-drained soil, full light and good humidity to thrive. It will tolerate a light freeze once established and it is very important to protect young plants.
Gold Leaf Orchid Vine also makes a wonderful container plant with staking or support. It is a must for every rare plant collection!

Using SUNSHINE Complete Nutrition System

For hydroponics and potted plants

Q: I recently bought both the 5ml of the sunshine epi and the 100 ml advanced nutrition kit. I read on the paper for the Epi not to use any other strong fertilizers along with this but I was wondering if it'd be alright to use both this foliar spray and nutrition watering together?

A: All solutions in SUNSHINE Booster Nutrition System (NPK-macro and micro-boosters) are compatible.
The only exception is Sunshine-Epi - brassinosteroid bio-stimulant. Epi should be mixed with distilled water separately from other boosters. The reason is, it is very bio-active, and if mixed with other compounds, oxidizes quickly which may affect its performance.

Sunshine-Epi solution must be prepared using distilled water and applied as foliar spray only (it only works on contact with leaves and not through the root system). Epi shows extremely impressive results when you apply it before the application of other nutrients because it increases plant metabolism; so all boosters become even more effective if you spray Epi the day before.

When using Micro- and Macro-boosters, you may mix all components in one watering can/tank (except for Epi), using regular tap water. Besides watering root ball, the macro-micro solution can be also used for foliar spray. It is optional, as in some circumstances growers prefer to keep leaves dry at all times: to stay away from mold, fungus and other issues caused by the wet environment.

Here is an example of Sunshine Boosters Nutrition System application:

Daily watering in one can: NPK 25 ml/gal (one of 5, depending on growth stage) + Constanta 5 ml/gal + Ca-Support 5 ml/gal, mixed in tap water
Every 2 weeks: spray Sunshine-Epi 2.5 ml/gal - to boost the immune system and growth rate, mixed in distilled water
From daily to every 2 weeks: Sunshine-Power-Si 25 ml/gal to protect from diseases and keep pH at 5.5-6.5. Can be used as often as daily and mixed with a daily watering solution (1)
As needed: Sunshine SuperFood and GreenLeaf - for correcting deficiencies. Can be also mixed with the daily solution (1)

Make sure to prepare a solution right before use and do not store solution for more than 1 day. Keep concentrates and solutions protected from bright sunlight.

Here is also advanced information on Sunshine Boosters compatibility.

Fertilizing in Winter?

Q: I'm a bit confused about what winter fertilization schedule I should follow in South Florida. For blooming plants, usually, I use a monthly granular bloom booster fertilizer as well as a liquid fertilizer every 10 days or so. Should I continue that schedule in the winter as well? Should I stop fertilizing altogether in the winter? How about fruit trees? What fertilization schedule should I follow in the winter?

A: Here is a general fertilizing schedule for established plants that we follow here in SW Florida.
The rule of thumb is, do not fertilize (with macro- NPK elements) when minimum temperatures drop below 65F and stay at that level for more than 7 days. At this temperature point, most of the tropical and subtropical plants slow down their metabolism and some of them going into dormancy. This means, nutrients are not consumed as much as during active growth period, and built-up nutrient supply within a plant plus whatever is available in the soil is just enough to get by through the winter. So additional fertilizing is not necessary. You may continue micro-element supplements and bio-stimulants throughout the year. In fact, it is highly recommended to do so, to help the plant survive cold spells. These are very effective tropical plant protectors:
SUNSHINE-Epi - Brassinosteroid plant hormone
SUNSHINE-Power-Si - Advanced plant protector with Silicon
SUNSHINE SuperFood - Complex microelement supplement

This rule is applied to both flowering and fruiting plants, in general. However, some species are winter-flowering and winter-fruiting. For those, you can make an exception and provide extra nutrients for flowering and fruiting, as long as the weather stays warm. During cold spells, avoid any NPK fertilizers and use only bio-stimulants and micro-elements. If you apply NPK during cold, it won't be consumed by a plant, build up in the soil, and may create a root burn situation.

In simple words, fertilize from March to October. Give plants some rest from November to February.
