SUNSHINE-SuperFood for your plants health

We are getting very high interest from our customers to our new plant booster SUNSHINE-SuperFood as well as many questions. We continue experimenting with the Jasmine that you saw in our previous newsletter, that had pale yellow leaves and numerous deficiencies. Right now, after only 2 applications, it looks healthy green again. Click on the picture to zoom in and see leaves turning from yellow to green within less than a month. See also full plant photo of this jasmine.

Q: Is SUNSHINE-SuperFood a fertilizer?

A: Traditionally we call a fertilizer macro-elements (NPK - nitrogen, phosphorus, and potassium). Technically, SUNSHINE-SuperFood is a complex of micro-elements that are essential for plant's health. It provides such elements as Mg, Fe, Mn, Zn, Cu, B, Mo, S, and Amino-acids that our soils are usually poor of. These elements are responsible for proper development of leaves, roots, flowers, and overall plant vigor. Read more about role of these micro elements.

Q: Can I just get these additional elements in a dry form and add to soil like a fertilizer?

A: No. Some of these elements must present in extremely low concentrations (this is why they are called micro-). SUNSHINE-SuperFood is a liquid substance with very high bioavailability that has very complicated formula; it is not just a mix of the elements. The formula is developed with the maximum efficiency for a plant to absorb through leaves and a root system.

Q: Is it better to spray leaves or water the plant with the solution?

A: Foliar applications are always most efficient in regards of seeing a quick result. However, we recommend to also drench the root ball with SUNSHINE-SuperFood solution to deliver the necessary elements evenly to all parts of the plant through its natural metabolism.

Q: My gardenia looks very sad after winter - most leaves are yellow and some have pale spots. Should I use SUNSHINE-SuperFood more often and in higher concentrations?

A: We recommend to apply SUNSHINE-SuperFood once a month to maintain a general plant health. In difficult cases like with this jasmine on the photo, you can do twice a month. However do not exceed recommended concentration. The rule of thumb is, you can apply water soluble fertilizers and supplements more often, but with lower concentrations - this way a plant will be more responsive. Plant metabolism in general is rather slow, changes take days and weeks - don't try to speed it up. Your patience will be rewarded.

Try SUNSHINE SuperFood on sick looking plants, especially with leaves that are yellowing, deformed or have spots (see photos of different deficiencies). There are no miracles, but this one works like a Miracle! All you need is a few drops of SUNSHINE SuperFood - item 6000! We also have bottles 50 ml and 100 ml for large plant collections and yard/landscape applications. Read more about SUNSHINE SuperFood...

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.
After harvesting, don't forget to make another treatment of SUNSHINE-Honey as a preparation for the next year flowering and fruiting season.

🌸 Why adenium?

Adenium collage
  • Easy to grow in containers
  • Thrive in sun or shade, indoors or out
  • Tolerant of low humidity
  • Very low water needs
  • Forgiving plants that tolerate missed watering
  • Long-lived plants that improve with age
  • Compact size, ideal for patios, balconies, and windows
  • Form unique, sculptural caudex shapes
  • Decorative even when not in bloom
  • Produce stunning, long-lasting flowers
  • Often blooming in a few months

🌸 Adenium Care Basics

Adeniums have many spectacular hybrids, and their basic culture is closer to orchids than to typical houseplants. The key is a small pot, excellent drainage, bright light, and careful watering.

Pot and Soil

  • Use a small pot sized to the root system.
  • Excellent drainage is required.
  • Use a very well-drained mix. We recommend specially formulated for Adeniums Desert Rose Soilless Mix

Light and Blooming

  • Give lots of light for heavy flowering.
  • In warm conditions and longer days, most hybrids and species begin blooming in spring.
  • In warmer climates they can keep blooming through fall and winter.

Watering (Most Important)

  • Adeniums dislike both extremes: over-watering and drying out too often.
  • Use neutral to hard water when possible.
  • Acidic water can sour the mix quickly and may cause root rot.
  • Water in the early morning so the plant can drink through the day.
  • Watering frequency can range from daily to every few days, depending on heat, light, and how fast the mix dries.
  • Never let the pot sit in a saucer of water.
  • Do not let the plant dry out too often, or it may go into early dormancy.
  • Do not wet the leaves.

Fertilizer (Caudex + Flowers)

  • To build a large swollen base/trunk (caudex), use a good quality fertilizer.
  • A fertilizer that helps trunk swelling also supports flowering. The best choice for this is Sunshine Megaflor.
  • Avoid fertilizers that are too high in nitrogen; choose a formula where the middle number is the highest.
  • Never apply fertilizer directly on roots.
  • Do not liquid feed a thirsty plant.
  • Always water lightly first, then feed, to avoid root burn and leaf drop.

The Caudex "Secret" (Shaping the Base)

  • At each repotting, lift the plant slightly so the upper roots are a little exposed.
  • This encourages new roots to grow downward and helps create a thicker, more interesting caudex shape.

Multi-Grafted Plants (Important Note)

  • Adenium hybrids can be multi-grafted with several colors/varieties on the same plant.
  • The swollen base forms only when the rootstock plant is grown from seed.

✍️ Adenium FAQ

How much light do Adeniums need?

Adeniums need lots of light for heavy flowering. Most hybrids and species start blooming when conditions are warm and days get longer, and in warmer climates they can keep blooming through fall and winter.

What is the best pot size for Adeniums?

Use a small pot sized to the root system, with excellent drainage. A small pot with excellent drainage is a must.

What kind of soil mix should I use?

Use only a well-drained mix. Adeniums do best in very well-drained soil. A small pot plus excellent drainage is the foundation of success.

How often should I water Adeniums?

Adeniums do not like both over-watering and drying-out too often. Water preferably in the early morning and do not water again until the mix dries on the surface. Watering can range from daily to every few days depending on heat, light, and how fast the mix dries.

Can Adeniums sit in a saucer of water?

No. Never allow your Adenium to sit in a saucer of water.

Should I wet the leaves when watering?

No. Do not wet the leaves.

What kind of water do Adeniums prefer?

Adeniums prefer neutral to hard water. Acidic water tends to sour the soil too fast and may cause root rot.

How do I create a large, swollen caudex?

At each repotting, lift the plant slightly so the upper parts of the roots are a little exposed. This encourages the plant to form more roots that grow downward and helps create a thicker, more interesting caudex.

What fertilizer should I use for caudex growth and blooms?

Use a good quality fertilizer to support both trunk swelling and flowering. Avoid formulas that are too high in nitrogen; the middle number should be the highest. Never apply fertilizer directly on roots, and do not liquid feed when the plant is thirsty. Water lightly first, then feed, to avoid root burn and leaf drop.

Can an Adenium have multiple flower colors on one plant?

Yes. Adenium hybrids can be multi-grafted with several colors or varieties on the same plant. Note that the swollen base forms only when the rootstock plant is grown from seed.

The Magic Number 65: when tropicals finally wake and the 7-Day Rule you should know

The Magic Number 65: when tropicals finally wake and the 7-Day Rule you should know 🌱

Discover the "Magic 65" rule for waking up your garden and the exact time to start fertilizing for maximum growth. Learn the specific temperature threshold that signals your tropicals to wake up and how to handle spring cold snaps.
  • 🌿 If you’ve been staring at your dormant trees and shrubs wondering if they survived the winter, you aren't alone. The most frequent question every spring is: "When will my tropical plants start sprouting?"
  • 🌿 While the calendar might say spring, tropical plants don’t use a watch - they use a thermometer. If you want to see green shoots and active growth, there is one "Magic Number" you need to watch: 65F 🌡

    • 🌿 The 7-Day Rule for Tropical Growth



    The gold standard for the tropical world is simple: plants generally wake up when minimum nighttime temperatures remain at or above 65F for at least one full week.

    • 🌿 Why 65°F?



    Tropical species are biologically programmed to stay dormant to protect their cell structure from cold damage. A single warm day won't fool them, but seven consecutive nights of 65F+ signals that the "growing season" has officially arrived. Once you hit that 7-day mark, you’ll see buds pushing and fresh leaves finally sprouting.

    • 🌿 Can You Force Them to Wake Up Faster?



    Patience is a virtue, but if you’re looking to "push" your plants, focus on two things:

🌞 Sun Exposure: Ensure they are in the brightest spot possible to warm the soil.
♨️ Heat Retention: Use dark mulch or move potted plants onto concrete surfaces that retain daytime heat.

    • 🌿 When to Start Fertilizing



❌ Don’t reach for the fertilizer until you see that active growth. Feeding a dormant plant can lead to root rot or wasted nutrients.
  • 👉 The Signal: After that first week of 65F nights.

✅ The Action: Once you see green tips, start your fertilization routine. This is when the plant actually has the metabolic "engine" running to use those nutrients.

    • 🌿 Watch Out for the "False Spring"



    Before you go all-in, ensure the risk of a hard freeze has passed. A minor cold snap - a few nights in the 50s - won't kill your progress, but it will act as a "pause" button. If cool weather persists, tropicals may "lock up" and return to dormancy. If that happens, simply reset your clock and wait for the next stretch of 65F nights.
  • 🌿 Ready for the Wake-Up Call? Fuel Your Tropical Growth!

Don’t get caught empty-handed when that 7th day of 65F hits. Stock up now so you can feed them the moment they wake up. Using the right nutrients during the active growth phase is key to lush blooms. Check out our curated selection of professional-grade fertilizers:

Checklist - preparing for winter in subtropical areas.
Watering. Start reducing the amount you water your plants in early fall, once the temperature drops below 65 °F. Avoid watering your plants during cool nights, as this may cause serious root rot.
Mulch. When a plant is protected by a thick layer of mulch, the root system stays healthy.
No Pruning. Avoid pruning, trimming, or pinching branch tips altogether during the fall and winter which encourages new shoots that are soft, tender, and very cold sensitive.
No Fertilizer. Avoid fertilizers during the winter. The main reason being the same as above for pruning: fertilizing promotes growth of the upper plant parts which should be avoided during the winter months.

Time to clean your yard!
In the South. It's getting cooler in subtropical areas, and garden work becomes even more enjoyable. Your garden now is in the most perfect shape after summer vigorous growth. It is the best time now to run the last trim before winter, as well as last fertilizer application. Clean up your yard without sweating off, add mulch to help plants to survive through possible winter chills. Don't forget to start reducing watering! Remember once temperatures drop below 65F, tropical plants slow down or stop growing and go into winter dormancy sleep.

Up North. When temperatures drop below 45 °F, start bringing sensitive plants indoors or into protected areas. Prepare/cover greenhouse, check availability of covers (sheets, plastic) and condition of heaters. Plants indoors will experience environment change, may drop leaves, and need different care than out in the sun. Reduce watering, check for insects once a week, and stop fertilizing until spring. Remember to pick the brightest spots for overwintering your tropical plants!

Enjoy cooler weather, fresh air, and thank yourself for a wonderful work you have done in your yard!
