Soil, media, substrate or just plain dirt, which is correct?

by Ed Jones, the Booster guy

...Dirt. What is it really and does it matter what you use to grow your plants? What is the right dirt for growing plants? In the growing industry, we refer to it as soil, media or substrate. In the real world, we just call it dirt. But is it? Is it just dirt or is it something special? We will try to give some good insight in this article...

How to prune mango trees for best shape and production

...Why should you prune your mango trees? There are at least 3 reasons.

  1. A good foundation is the key to strong growth and a shapely tree.
  2. If you get your mango tree started off on the right foot with a strong foundation, it becomes much easier to keep it shaped nicely.
  3. It will be forced to produce more branches allowing for more places for fruit production.

Edible Landscape: fruit bearing hedge

Photo above: Biquinho Pepper (2 months old plant)

Q: My mom had to remove a hedge for some renovations and after being heartbroken about losing my little bird haven, I've decided to plan on a fruit bearing hedge that offers some privacy and places for the little fledgling to wait for food. Any suggestions? I was thinking blueberries or citrus but open to any ideas.

A: Below are a few suggestions for a fruit bearing hedge planted with fast-growing, tropical species. They will contribute to a nice edible landscape for both your family and the birds - they will be very happy!

Larger size hedge (small trees), grows full-size within 1 season:
- Loquats
- Dwarf Mulberries (very cold hardy too) such as Dwarf Everbearing

Medium size hedge (shrubs or vines), 2-3 seasons to grow full size:
- Black Surinam Cherry Lolita
- Blackberries and raspberries

Low hedge (4-5 ft tall, 1 season, fast growing):
- Biquinho Pepper
- Wiri Wiri Pepper

Citrus is probably not a good idea, not bird's favorite, and blueberries require a special acidic soil here in Florida, so they will need extra maintenance, special soil, and heavy mulching.

Mango Talk: How to prune mango trees for best shape and production

by Ed Jones, the Booster Guy

...Why should you prune your mango trees? There are a few reasons.
First, a good foundation is the key to strong growth and a shapely tree.
Second, if you get your mango tree started off on the right foot with a strong foundation, it becomes much easier to keep it shaped nicely.
And third - it will be forced to produce more branches allowing for more places for fruit production...

...We received our Mango tree in late February of 2020 as a relatively small plant in 3 gal pot...
...The opening photo was taken just last week and you can see that as she grows, her shape is very nice...
...She is now about 7' tall and just as wide. She has a great foundation and a lot of branches. We also have less grass to mow. She also got her very own marker painted on a brick:

...We have also enlarged the circle of mulched area under the tree to allow it to be able to get nutrients from it's SUNSHINE Boosters Mango Tango without having to compete with the grass. This is one mistake that I see frequently in my neighborhood with all trees...

Fertilizer and the Fall Garden

by Ed Jones, the Booster Guy

...Well Labor Day has come and gone. Summer is winding down and depending on where you live, thoughts are now turning to pumpkin spice, witches, fall decor and gardening. Wait, did I just say gardening? Yes, if you live in the deep south, and I do, it is time to think about fall gardening and fertilizer. Even those of you in the north can put in a few quick crops now for fall. Think onions, radishes, lettuce and other greens and of course, garlic...

Next month, we can start putting out our plants that do better in cooler weather. We will put out some beans and of course cabbage. We may do some potatoes too. What do you like to grow?
But what about fertilizer? Glad you asked. Now, most of us have our favorite brand of fertilizer. Some of us had some secret fertilzers that we used in the past. For me it was composted alpaca manure. Yes, we raised alpacas in the north, but that is another story for another day....

...Once the temperatures have begun to drop, it is better to use a good liquid fertilizer. The one I will be using this year is SUNSHINE Robusta. SUNSHINE Robusta is an organic amino acid based liquid fertilizer that is safe to use with every watering. It uses amino acids to chelate (bind) micro-nutrients and makes it easier for plants to take them up from the soil. Most fertilizers use EDTA to chelate their micro-nutrients and plants must use about 4 times more energy to break them down than they do with SUNSHINE Boosters. This means that your plants will have more energy to put into growth. And isn't that what we are after?
With Special Seasonal price for 16 oz bottle reduced to only $19 with FREE shipping, this is your best choice of organic, safe fertilizer for your vegetable garden!..

How to grow Cerbera and make it flower

Q: I purchased Cerbera manghas - Enchanted Incense a year ago. As you see from the photo, it's doing great however, no blooms. I fertilize properly and very often and use worm castings for micronutrients. Yes it's not "your" fertilizer, but my plumerias, that are also in pots they are over 5 feet tall and blooming like crazy. I don't see any inflows coming on the Cerbera at all and it is hot and humid here in North Carolina, so it's happy but no sign of blooming. What is your advice?

A: Top Tropicals first brought Cerbera manghas into the US plant market a few years ago, it was recommended to us by our friend, plant taxonomist John Mood who visited Thailand, and among other exotic plants noted this fragrant beauty. Since then we've been successfully growing this plant, it has become one of everybody's favorites.

Generally speaking, Cerbera culture is very similar to Plumerias. These plants are closely related. So if you know how to grow Plumeria, you sure will succeed with Cerbera. Hot and sunny location, well-drained mix, moderate water and bloom boom fertilizer will do the trick. However, we have noticed a few distinctive features that make this plant somewhat challenging at times.

1) Flowers

For past years, we've been studying what triggers its flowering. Sometimes these plants start flowering in 1 gal pot, 1 ft tall. Other times a large developed tree 5-6 ft tall, in 5-7 gal pot, grows beautiful foliage with no signs of flowers. Eventually all of them bloom, no matter how stubborn they are, it's just some individual plants start flowering sooner than others, all grown in the same conditions.
One of our plants in the ground, a well-branched tree, was covered with flowers for a few months, but only on the 3d year after planting. Before that, it only produced a few random blooms. Others bloomed in pots at very young age.
The following factors benefit to Cerbera flowering:
- full sun at least 10 hours a day
- hot temperatures above 85F
- regular water but not heavy rains
- regular fertilizer - Bloom Booster type
- very good drainage and drying out before waterings. If root ball stays moist, the plant may look healthy but won't set flower buds. Keeping on a dry side will encourage flowering. Very similar to Jasmines: they bloom like crazy in April while it's hot and dry in Florida, but once our summer rainy season starts, they reduce blooming.

We highly recommend using Sunshine Megaflor bloom booster or SUNSHINE Pikake in combination with micro-element supplements Sunshine Honey (B-Mo) and Sunshine Superfood (complex micro) that induce flowering. Dry and granulated fertilizers may not supply exactly what a plant needs: certain elements that trigger flowering may be missing. Sunshine Boosters formulas are scientifically balanced, they contain precise amounts of nutrients needed for setting flowers. Besides, excessive salts from regular dry fertilizers create nutrient lock up that may retard plant metabolism; with liquid amino-acid based Sunshine boosters, plants consume the whole menu of elements without building them up in the soil.

2) Fruit

Fruit of Cerbera are very pretty and cover the tree after profuse flowering. To inexperienced eye they may look very much like small mango or avocado fruit - so make sure kids or visitors don't try to eat them! Cerbera seeds are extremely poisonous.

3) Leaves

If you ever grew Passiflora or Milkweed, you know how leaves can be eaten by caterpillars overnight. This may happen to Cerbera too, as we discovered. In Florida environment this exotic plant doesn't have natural predators for protection from certain insect species that may feed on it. So watch out and if noticed first signs of leaves damage - its time for insect control.
Other than that, Cerbera foliage is usually beautiful and colorful, here in Florida it looks much healthier than that of Plumerias often affected with rusty residue during high humidity months.

Hope this helps. The Cerbera fragrance is enchanting, it is worth the efforts and waiting!

Planting during hot summer

In the photo: Malpighia glabra - Barbados Cherry, Acerola

Q: We just moved to Florida from New York. The weather is so hot and I wonder if I should wait till Fall to plant my garden? I tried to plant some seeds of annuals but nothing grew, just weeds. I also planted tomato seeds, they germinated but died in few days. What am I doing wrong?

A: Growing from seeds during hot season can be tricky. Here in Florida, we still can grow anuals and vegetables from seeds, but only during winter season. Annuals and tomatoes need cooler temperatures and protection from rain water which we have in abundance during summer. Combination hot + wet can kill those seedlings. On the other hand, seeds of tropical species love the heat and humidity, and germinate in no time, they just require a little experience.
However, Summer is a perfect time to plant and establish starter plants in your garden.

Five advantages of summer planting

1. Root growth. High temperatures promote rapid root growth - this is one secrets of a plant nursery. If you grow plants in pots, putting a pot on top of black ground cover will increase the effect, and the roots will grow even faster than the tops! This is a great head start for a plant. Make sure to provide adequate watering.
2. Fast development. With bright sun and longest day light, photosynthesis is more efficient. In simple words, during hot summer tropical plants have faster metabolism, they produce cells faster and grow leaves and stems faster.
3. Bugs be gone. Bright sun in combination with good air circulation will help to stay away from insects, leaf fungus, and other diseases.
4. Fertilizing can be generous and will be most efficient. In summer, there is less chance to overdose, as plant food is consumed fast, and summer rains help to prevent nutrient lock up in soil.
5. Rain water works like magic. Rainy season in Florida is our blessing. It can not be replaced by sprinklers or even daily hose water. Rain penetrates evenly and saturates not only a root ball but also the surrounding area that gives room to spread even bigger roots. Rain water also works like a "flush" to rinse off all excessive salts that may build up in soil.

As a result, plants will establish faster and grow bigger before winter, which will give them a better chance to survive possible cold spells.

Plant in summer and watch plants grow healthy and happy every day!

Black Magic of Colocasias

Spectacular unusual plants

Q: I need something unusual to plant next to a small pond at my front yard. It is full sun location. I need a plant that is not too messy and doesn't require much maintenance. Preferably without flowers, so they don't drop into the water, and not too tall. Any suggestions?

A: Your ideal solution is - colorful Colocasia hybrids with spectacular large leaves. Our favorite is variety Black Magic - it creates a magic tropical atmosphere. The color of the leaves in full sun is dark purple, almost black, and the brighter the light, the deeper the color.
Light colored varieties - Royal Hawaiian Maui Sunrise, with bright sunny stripes, or Illustris, in case you want to create a bright, mixed-color border around your pond. Colocasias are perfect plants for perimeter borders, and naturally are marginal plants around lakes and along river banks.

Kristi's Loquat Tropical BBQ sauce

Loquat trees are famous for their abundant fruit production. Many customers who purchased this tree from us, soon end up with some serious crops and start asking if we have any special recipes for loquat fruit - because you can only eat so much out of hand! Here is our manager Kristi's favorite Loquat recipe - not only delicious and tropically-aromatic, but also good for you. Happy Tropical Meal!

Ingredients

2 lbs loquat fruit

  1. cup soft brown sugar
  2. cups malt vinegar
    1 onion chopped
  3. cloves garlic

    1/2 tsp salt
    1/2 tsp black pepper
    1/4 tsp cayenne pepper
  4. cloves whole or 1/2 tsp ground cloves

    Instructions

    Wash the fruit, cut them in half and remove stones. The loquats will lose about a third of their weight once stoned (3 lbs of whole fruit = 2 lbs of fruit, stones removed). Add loquats and all remaining ingredients to a large saucepan. Bring to a low boil, then simmer for about an hour, stirring occasionally. The liquid will have reduced quite a bit and the fruit will be collapsed and very soft. Allow to cool slightly, then liquidize the sauce in a blender or a food processor. Be careful, hot sauce really burns!


This delicious tropical sauce is great for any BBQ - with meats or fish. Enjoy!

Tahitian Gardenia

Q: I am interested in your Tahitian Gardenia and I would love to try and grow this plant in a large container/fabric pot. The soil here where I live is terrible as it's hard rock, clay, and sand! So I'm not sure if amending the soil would help to plant in the ground? Can you tell me if this will do okay in a container or best in ground? I live here in Las Vegas, NV (zone 9a). Any information would be great to help me make a this decision, I love the selection of cool tropical plants you offer! Also my daughter does Tahitian/Polynesian dance and this would be a cool "topping on the cake" if she could have a live Tiare flower in her performances.

A: Tahitian Gardenia will be doing best if grown in container in your area. In its natural habitat, it grows full sun but also it enjoys mild weather conditions and high air humidity. All gardenias prefer acidic soils. In your area, if planted in the ground, it may be exposed to some harsh conditions: too high temperatures, too hot sun, dry air, and as you mentioned - heavy clay and sandy soil. You can enjoy this plant grown in container, which can be moved as needed away from too much sun during summer months. Use well-drained potting mix. Use plastic pot, do not use fabric or clay pots - soil will dry out too quickly.
Also remember to fertilize this plant on regular basis with a liquid fertilizer SUNSHINE Pikake - Fragrant Flower Booster.
Grow gardenia in full sun or semi-shade during the hottest months. You may spray it with pure water if the air too dry and hot. Enjoy your Tropical Beauty and good luck!
