Healthy Plants: Q&A from Mr Booster

What is an ideal potting mix?

Q: A few years ago, I purchased a Barbie Loquat from you, and I'm pleased to say it's been growing very well. I now have several loquat seedlings. I have read that a well-draining medium should be used, and I have found that the various formulations provided on the web for such medium seem vaguely reminiscent of the recipe provided in your transplanting instructions. Therefore, I would like to retrieve your recipe, unless you could recommend an even better one?

A: The main requirements for a good potting mix are:
- perfect drainage, allowing air circulation that is so necessary for healthy roots; oxygen circulation helps to avoid root rot
- water retention: to keep nutrients in soil
- low pH (soil acidity) which is important for most tropical plants
- adequate amount of organic matter in the mix, in combination with proper fertilizer program

In our nursery we experimented with many different potting mixes for the past couple decades. We ended up with an ultimate mix for tropical container plants that we designed ourselves. This custom mix is called -

Abundance - TopTropicals professional soilless potting mix

It meets all the requirements above which makes it a perfect mix. All our plants are happy with it. Abundance is a professional quality (nursery-grade) potting mix with great drainage characteristics, ideal for any tropical plants. It is organically derived soil-less mix, free of any additives.
Ingredients are:
- fine Canadian peat moss
- coconut coir
- perlite
- aged pine bark (soil conditioner).
See more info on soil mixes.
We have this mix available for purchase in different packaging sizes - 2, 3, and 7 gal bags.

Besides proper potting mix, all container plants require regular fertilizing. We recommend the newest, scientifically balanced fertilizers Sunshine Boosters that are natural, eco-safe, great for all edibles and organic gardening. They are safe to use with every watering, provide all necessary elements for plant daily needs, and won't burn the roots.
For your loquat tree, consider Sunshine C-Cibus, it boosts both flowering and fruit production. Loquat is Winter-Spring bloomer, hopefully you will get some crop soon!

Feeding Indoor Plants

Q: I am moving all my potted plants indoors as weather is cooling down. I still have Sunshine Boosters that I got from you in Summer. Do I need to continue fertilizing and how often, or should I wait until Spring?

A: Indoor plants add a vibrant warmth to your home, and can even improve the air quality. But most importantly, indoor plants give you access to year-round gardening. While majority of house plants are easy to maintain, they still require proper care to thrive.
Too many gardeners overlook the importance of fertilizing plants indoors. However, proper feeding is essential to grow healthy, vibrant plants. With outdoor plants nature sends rain and a plant will send new roots to find food, an indoor plant is limited to only what you will give it. That is why it is essential to feed your plants a healthy nutritious meal even indoors.
Many granular and slow-releasing fertilizers will recommend that you only feed your plants occasionally, but this is not the healthiest for plants, since they need to "snack" every day to satisfy their daily nutrient needs. When you feed a plant a large meal rarely, it cannot absorb the nutrients effectively, leftovers creating build up in soil (it's called "locked up nutrients") and that is why we specifically designed our fertilizers to be a light, daily nutritious meal for your plants - Sunshine Home for houseplants...

How not to kill gardenias?

Q: I have tried to grow gardenia in pots for years and never keep them alive. When i look on camellia websites they say fertilize potted plants twice a year. I'm confused as I tend to kill them with kindness haha. Also, if our tap water has high cal/mag and that stops the gardenia getting other nutrients why would I make up the feed with tap water? So confusing and online is mixed messages...

A: Gardenias are not the easiest plants to grow, however, they are easier in pots than in the ground: they prefer acidic soils, and in many areas soils are alkaline. The most important factor is balanced and sufficient nutrients. In the ground, plants have no limits to reach out to different elements by spreading their root system. In a pot, once all the good stuff is consumed, plants start suffering nutrient deficiency. This is why a balanced feeding program is important.

Generally speaking, Cal/Mag in tap water cannot be bad, because they are essential elements, good for plants (in proper amounts). However, just Cal/Mag is not enough. This is why you need a balanced liquid fertilizer for plants that prefer acidic soil. Excessive Cal/Mag alone can create nutrient lock up, especially if they are chelated with EDTA like in dry fertilizers, which are not fully accessible for plants.
We recommend natural, Amino-Acid based fertilizers that are completely consumed by a plant and are safe to use with EVERY watering, even in Winter. They are scientifically formulated and cover all plant needs. For your gardenias, you should use SUNSHINE Pikake - Fragrant Flower Booster.
Another important factor is proper watering. Gardenias like regular water but don't like wet feet = well drained potting mix is a must, similar to Abundance professional growing mix.

How to keep bugs away naturally?

Q: I started moving my tropical plant collection indoors as it's getting colder... And all of a sudden, I noticed bugs on leaves! I know for sure all my plants were bug-free when I kept the pots outside in my lanai. What happened? And how can I keep them clean and healthy without using any harsh chemicals? I have many edibles and herbs that I use in my cooking and prefer to stay away from insecticides. Any suggestions?

A: It is very common when healthy looking plants, once moved indoors for the winter, get insect infestations. The main reason is change of environment that puts a plant into stress and makes it susceptible to parasites and diseases. Just think about what a plant is missing, a whole combination of necessary conditions that provided a good life:
- Bring light -> light level reduced, so beneficial UV spectrum is gone
- Air circulation -> less wind = more bugs thriving
- Warm temperature -> from upper 80's in summer to 70's in your AC room
- Air humidity -> although humid air is believed to be causing some issues (for example fungus), however, reducing humidity overall puts a plant into stress and makes it more vulnerable.

Healthy Plant Food: Q&A from Mr Booster

Why my Sapodilla is not fruiting?

Q: I bought a Sapodilla tree from you several years ago, Silas Woods. I live in Houston area. The tree grows and produces blossoms for fruits, but then they just dry up and fall off. To-date, I have not gotten any fruits off the tree. Is there a reason for this? I really want a fruiting tree because Sapodilla is one of my favorite fruits. I have attached pictures of the tree. Please help.

A: Silas Woods is a free-flowering variety and in favorable conditions it should produce fruit almost year round, considering warm temperatures. The fact that the tree is producing flowers indicates that it is strong, overall healthy and ready for production, but for some reason these flowers don't set fruit. There may be several reasons for such behavior.

1) Too high temperature and too low humidity
In Houston area, humidity should be good in summer. However, if temperatures stay above 90F for a long time, this may cause flower dry-n-drop.
Solution: try to move the potted tree into filtered light, or in a spot where it does not get direct burning sun during the hottest hours of the day (morning sun is the best)

2) Root bound.
Solution: check if the tree needs stepping up into a larger container.

3) Lack of certain nutrients that are responsible for proper fruit formation.
In particular, elements B (Boron), Mo (Molybdenum), and a few other micro-elements (Fe - iron, Cu - Copper, etc.). This is most likely the cause of a flower drop. This is very common reason for undeveloped fruit or lack of fruit in container-grown fruit trees. When grown in the ground, plants can reach out to all necessary elements in surrounding soil (considering soils are not too poor on necessary elements). In a pot, a supply of nutrients can be exhausted very quickly, so a quality fertilizer program is very important. Fertilizer must include all necessary nutrients in easy accessible form, and a plant must have their constant supply for proper development.
Solution: prescribe to your Sapodilla tree the following combination of plant food:
- SUNSHINE C-Cibus - Crop Nutrition Booster. It will provide well-balanced amounts of high absorption Nitrogen, as well as other macro-elements - to provide enough energy to the tree, plus a combination of all necessary micro-elements. It is safe to apply this fertilizer as frequent as with every watering, including winter time.
- SUNSHINE-Honey - sugar booster. This supplement has a high content of elements Mo and B - once the tree starts getting them on regular basis (a few times a year, according to the label), it will change its habit dropping flowers and/or premature fruit drop. As extra bonus, Sunshine Honey makes fruit sweeter by bringing sugars from all over the plant and concentrating them into fruit.

4) Lack of pollinating insects.
Solution: For most effective pollination, we always recommend to put some pieces of fruit under the tree, apple peels, or even banana peel. Those attract tiny beetles that are responsible for small flower pollination.

With winter time approaching, fruiting season is about to end, however, do not get discouraged and start the fertilizing program right away: this will bring up the plant into a healthy stage within a few months, and by next season it should be covered with fruit you like so much! Remember, Sunshine liquid fertilizers can be used year round, including winter, without a risk to burn roots or overdose, as long as you follow label instructions.
