Healthy Plants: Q&A from Mr Booster

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 get Jasmines to flower

Q: On the picture, these are a few of the jasmine plants that I have from Top Tropicals. I have bought so many plants from you over the years, not just jasmine. I have several varieties of jasmine. They were all doing very well. However this year I didn't get a single flower. There are a lot of buds... But before the buds open they become brown and withered. I bought fertilizer from you. Fertilized the plants once a month like I always do. I water the plants once a week. I repotted the plants hoping that would take care of this problem. Some of the jasmine plants I pruned... the plants came back vigorous growth with a lot of buds... BUT it is the same problem! Please help.

A: One of the possible reasons why they have flower issues is - maybe they don't have enough sunlight. They need to be in full sun all day long for profuse blooming and proper flower forming. However since the buds are forming, there may be just enough light. In this case, dropping buds may be a sign of overwatering.

Important steps - how to make Jasmine Sambac flower:

1. Soil. Use only well-drained soil

2. Water. Keep plants on a dry side and never over water. If the top of the soil is still moist, do not water.

3. Sun. Keep in full sun all day long. The more sun, the more flowers.

4. Bloom booster. Use Flower booster fertilizers:
Pink N Good Daily Plant Food - Flower Booster
Fragrant Plant Special booster, this 90-day Smart-Release container plant food:
Plumeria Top Dress - Smart-Release Booster
Do not use fertilizers with high Nitrogen (1st number in NPK formula) - those will promote more leaves instead of flowers.

5. Micro-elements. Use Apply micro-elements, they will help the plant to develop healthy and long-lasting flowers:
SUNSHINE SuperFood - plant booster

10 key tips for successful overwintering of tropical plants indoors

1. Maximize Light: The more light, the better. There's no such thing as too much indoor light. If windows aren't enough, use LED grow lights, which stay cool and won't dry the air. Rotate plants every few days to prevent uneven leaf loss.

2. Reduce Watering: Less light and cooler temperatures mean plants need less water. Allow the soil to dry between waterings, and avoid overwatering - combination of cold + wet is especially harmful.

3. Maintain Moderate Temperatures: Most tropicals are happy with daytime temperatures around 75F and nights at 50-60F. In sunrooms or greenhouses, some can handle 45F if watering is kept to a minimum.

4. Boost Humidity: Avoid placing plants near heaters or vents that dry the air. Misting daily helps, or place pots on trays filled with water and pebbles to raise humidity around them.

5. Monitor for Pests: Check leaves weekly to catch insect problems early, as pests can cause serious damage or even kill the plant indoors.

6. Fertilize Smart: Use ONLY liquid, amino-acid-based fertilizers like Sunshine Boosters throughout winter; they won't burn roots since their dosage adjusts with reduced watering. Avoid dry, granulated, and EDTA-based fertilizers during winter and dormancy.

7. Use Micro-Nutrients: Along with macro-elements (fertilizers), supplement with micro-elements like Sunshine Superfood and bio-stimulants such as Sunshine Epi to build strong plants with robust immune systems, better able to withstand unfavorable conditions and resist diseases.

8. Hold Off on Pruning: Leaf drop and leggy growth are normal responses to winter. Wait until spring to prune, when new growth starts, to encourage branching and healthy foliage.

9. Don't Repot Yet: During dormancy, roots slow their growth. Repotting too soon risks root rot. Wait until spring when new growth appears to transplant into a larger container. Typically, roots grow in proportion to the above-ground parts.

10. Let Them Rest: Winter is a natural resting period. Avoid forcing growth - your plants will reward your patience with vibrant leaves and flowers when spring returns.

Tropical analogies of non-tropicals

By Kristi, the Florida girl...

...When I first started working at Top Tropicals eight years ago I knew nothing about plants. I didn't even know which ones I liked. Over the first few months I took in information on plants like I was a starving kitten who had just gotten its first meal in weeks...

...What I started to notice was that the plants I tended to gravitate to were more cold weather plants. Plants that couldn't be grown in the hot summers in Florida, and vines. Seemed like everything I set my sites on was a large vine or couldn't grow in the heat...

...Many of our local customers are from up North as well and are used to these colder weather plants too. This got me thinking, I wonder how many of these people are missing the plants they grew up knowing and loving. I know there are at least a few from the conversations I have had with some of you at the nursery. So, I decided to make a list of a few of the plants that will grow here that are similar but not the same and, in some instances, even better!..

Plant Horoscope. Scorpio Zodiac lucky plants: Plants with thorns, red in color, and grow under adversity

Scorpio - 10/23-11/21.
A WATER sign ruled by both Mars and Pluto.
Scorpio's plants are often found in remote places or on poor ground. They will likely have thorns, can be red in color, and grow under adversity. The good news is, most of these plants are nearly indestructible! This makes them desirable for every gardener.
The reproductive organs are ruled by Scorpio, so these are plants that balance the hormones, regulate the menstrual cycle, help with childbirth and pregnancy. Until this century, Scorpio was ruled by Mars, and the herbs associated with it had to do with the urogenital system and the colon. Many of the herbs related to Scorpio are cleansing and revitalizing. Now, astrologers assign Scorpio to Pluto, discovered in 1930 (Pluto is said by astrologers to be a higher octave of Mars). Physiologically, Scorpio involves the processes of catabolism and anabolism, the death and regeneration of body cells. Diseases of Scorpio are often involved with the slow buildup of toxic substances in the body (carcinogens, etc) or in the mind (anger, jealousy). Scorpio loves a spice with depth and complexity. Camphor Basil adds rich flavor to every dish it seasons, and its own aphrodisiac tendencies appeal to Scorpio's lusty nature.

Scorpio Zodiac lucky plants:
Ceiba, Baobab, Pistachio, Nutmeg, Thunbergia, Combretums, Dragon fruit, Medinilla, Camphor Basil, Oregano, Vanilla orchid, Hibiscus, Various cacti and succulents, Adenium, Honeysuckle, Peppers, Cordyline, Spider plant, Jasmine, Gooseberries, Wild indigo, Bougainvillea, Aloe vera, Raspberry , Palmetto, Horseradish tree, Camphor, Allspice and Bay Rum,Jujube, Sweet Mimosa, Agave, Milkweed, Hong Kong Orchid Tree, Pony Tail, Dwarf Poinciana, Bottlebrushes, Clusias, Crocosmia, Zig-Zag Cactus, Dracaena, Fire Bush, Hoyas, Jatropha , Kalanchoe, Sausage tree, Devils Backbone, Pereskia, Red Plumeria, Firecracker, Rattlebox, Rhoeo, Calendula, Geranium, Thistles, Mint , Sage, Catnip, Coriander, Sandalwood, Ginseng, Euphorbias, Acacias.
