Why is my palm tree turning yellow?

🌴 Why is my palm tree turning yellow?



Yellowing leaves are a common concern with palms and can be a sign of several issues, most commonly: nutrient deficiency and pests or disease. Additionally, leaf yellowing may be a sign off overwatering or poor drainage, underwatering, or cold damage.
  • ✔️ Nutrient deficiency


    Nutrient deficiency is the most frequent cause of palm issues. Palms are heavy feeders, and even a slight imbalance can lead to yellowing. Lack of nitrogen, magnesium, iron, or potassium is the leading cause.
  • ✔️ Signs of nutrient deficiencies:


Magnesium and Iron deficiency is one of the top culprits, especially in sandy soils. It causes older fronds to turn yellow with green veins.
  • Potassium deficiency causes yellow or orange spots on older fronds.
  • Nitrogen deficiency leads to overall pale yellowing, especially in new growth.


✔️ How to fix?


Use a slow-release fertilizer with high Nitrogen content, like Green Magic, that includes all these elements; with 16-6-11 grade and 6 months release, it turns plants green very quickly! You can also use a balanced liquid fertilizer like Sunshine Robusta. Additionally, a supplement of magnesium sulfate (Epsom salt) and micro-element supplement containing chelated Iron can help, like Sunshine Superfood (amino-acid based natural product).
  • ✔️ Pests and Diseases


    Pests and fungal diseases can lead to yellowing. Check for signs of scale, mites, or fungal and bacterial problems, especially if yellowing is uneven or spotted.
  • ✔️ Signs of pests:


Thrips cause silvery-yellow streaks or mottling
  • Spider mites, especially in dry conditions, cause yellow speckling
  • Scale insects can suck sap and weaken fronds
  • Mealybugs often found in leaf bases and crowns


✔️ How to fix?


Inspect your palm regularly and treat pests early with neem oil, insecticidal soap, or horticultural oil.
  • ✔️ Lethal yellowing


    Lethal yellowing is a serious disease caused by a phytoplasma, a type of bacteria-like organism. It affecting mostly Coconut palms and some other species like Phoenix (Date) palms. It causes premature fruit drop, yellowing of fronds starting from the lower ones, and eventual death of the tree.
  • ✔️ How to fix?


    Unfortunately, there's no cure, but early removal of infected trees can slow the spread. Disease-resistant coconut varieties are available.
  • ✔️ Other causes


Overwatering or Poor Drainage: Too much water can suffocate roots and lead to yellowing. Make sure the soil drains well and let it dry slightly between waterings.
  • Underwatering: Dry soil for too long will stress the palm. Water deeply but infrequently.
  • Cold Damage: Exposure to cold temperatures can turn fronds yellow or brown, especially in tropical varieties.


✔️In most cases, leaf yellowing isn't fatal, but it's a sign your palm needs attention. Focus on balanced feeding, proper watering, and pest checks to keep your palm healthy and green. Trim only fully dead fronds - yellow ones still provide nutrients to the palm. With proper care, your palm should green up again.

Hibiscus: TopTropicals' first plant

- September 2001 @ TopTropicals -

Q: I wonder how you started your plant business and what was your first plant?

A: It was 20 years ago this month that we started Top Tropicals Project. No idea where it was going or how to even get "there", just started with the idea of sharing these wonderful creatures we call plants with anyone and everyone who felt the same way.

Believe it or not, the first plant at TopTropicals was a hibiscus. Right before we opened our plant nursery in Florida, we ran into a place called Winn Soldani's FANCY HIBISCUS. The variety of colors inspired us to start our own tropical plant business. We asked the owner Winn Soldani: what plants do you suggest us to grow in Florida? His answer was, "Your plant will find you". Very soon we discovered jasmines, then perfume trees and fruit trees - all those became our specialty. Then very quickly TopTropicals.com turned into a large Plant Mall where you can find every tropical plant you can think of!
But at TopTropicals we still grow hibiscus!

Hibiscus Plus

Hibiscus is a wonderful plant, considering there are thousands of hybrids with color palettes you can only imagine. Especially interesting are those rare and useful species, yet very easy to grow, such as:
- Salad Hibiscus - Hibiscus furcellatus - yes, used in salads
- Coral Hibiscus with crazy pendant flowers - Hibiscus schizopetalus
- African Cranberry hibiscus that is used for making teas and salads - Hibiscus acetocella
- Cotton Candy Hibiscus mutabilis - the flower changes color, opens as white and turns into bright pink within 3 days, like Yesterday-Today-Tomorrow

Care of Hibiscus and other flowering tropicals

"If your plant isn't flowering, feed it."
- Winn Soldani, Fancy Hibiscus -

Among gardeners, Hibiscus plants have a reputation to have couple maintenance issues:
1) they can get bugsy (because they must be so tasty!)
2) they can get leggy, especially fancy grafted cultivars, and after a while they don't look as perfect as when they came from a nursery.

4 tips for healthy and pretty hibiscus plant

1. Full sun. Essential for profuse flowering and keeps away diseases.
2. Pruning. Keep it pruned and it will get bushy and produce more blooms.
3. Well-drained soil. Hibiscus likes regular watering but hates wet feet.
4. Nutrition program. Hibiscus plants are heavy feeders. But keep in mind that if you just keep pushing granulated plant food, you can over-fertilize the plant. Excessive salts will accumulate in soil and you will end up with a sickly looking plant.

Keys to balanced plant food and bloom booster

1) Use liquid fertilizer, preferably amino acid based, it won't create nutrients lock up
2) Fertilize on regular basis, it's better dilute concentration and add food with every watering
3) Always add micro-elements - they are essential for plant health

If you do this part right, the result will be:
- healthy, green plants, like they just came from a nursery
- reliable blooming circle
- better cold tolerance and disease resistance. Remember that a strong plant will be less stressed and less "bugged" by bugs!

We always suggest Sunshine Boosters - scientifically balanced liquid fertilizers that are amino acid based = they are natural and organic, can be used for both flowers and edibles, and what's most important - year around. They are safe to use virtually with every watering.

This is all you need for healthy plants and lots of flowers!

Growing Nutmeg from seed: secrets of successful germination

TopTropicals.com

Q: I received a Nutmeg nut and I am wondering do I need to open a hard shell before planting it? Any other tips on growing nutmeg from seed? When will you have Nutmeg plants for sale?

A: We just received fresh nutmeg seeds from Sri Lanka and planted them right away, so we should have Nutmeg plants by Spring/Summer. These are some tips on how to make germination a success:
- nutmeg seeds are viable only for a few weeks after harvesting so plant them as soon as possible.
- wash the seed and soak it in warm (100F) water with a few drops of SUNSHINE-S booster that improves germination. Soak for up to 24 hours. You may use a thermos to keep it warm.
- there is no need for scarification. The outer shell of nutmeg is hard, however, it is not thick so the water will penetrate easily. On the photo above, you can see 2 seeds: the one on the right expanded twice in size after sozking.
- Plant in a porous soilless mix, preferably light seed germination mix, in 4-6"pot, and keep moist but not soggy. You may cover the pot with plastic to keep moisture in.
- Unless you are germinating the seed in hot tropical conditions, you should use bottom heat - 80-85F. A heating pad is the best solution (make sure it doesn't have a timer that automatically shuts it off). For safety, use GFI protected electric outlets since you will be watering the pot.
- Be patient and allow a few weeks for germination. Once the seed sprouted, keep it in bright filtered light and apply SUNSHINE Superfood to young seedling, along with a small dose of Slow Release Fertilizer, for kickstart.
- Move the seedling out in bright sun light once the temperature outside is above 70F.

We have a very long waiting list for Nutmeg plants (item 3878) and seeds (item 6203), so you may reserve one for yourself using our Wishlist form; this way you will be notified immediately when we have the plants in stock, as they won't last long. A few seeds are still available for sale, order now while they are fresh:

Repotting tropical plants

Orange  cat  with  indoor  plants

By Alex Butova, the Witch of Herbs and Cats

Q: When is the best time to repot tropical plants?

A: Repotting tropical plants is vital for their overall health and growth. The best time to repot them is during the Spring through early Summer, when they start active growth.

Start by selecting a well-draining soil mix that consists of equal parts potting soil, peat moss, and perlite. Gather the necessary supplies, including a slightly larger pot, the soil mix, and a good fertilizer

Carefully remove the plant from its current pot, trim any damaged branches, and place it in the new pot with fresh soil mix. Be sure to position the plant with the growth point slightly above the soil level. Water the plant thoroughly but avoid overwatering. After repotting, find an appropriate location with suitable lighting conditions for your plant. Monitor the moisture levels and water when the top inch of the soil feels dry.

Additionally, apply the appropriate Sunshine Boosters fertilizer according to the instructions on the packaging. Use Sunshine Boosters fertilizers for specific plant needs (Robusta for foliage, Megaflor for flowering, Ananas for pineapples, etc.). It is safe to apply Sunshine Boosters all year around. Keep a close eye on the plant for any signs of stress or issues and adjust your care routine as needed. Help the plant to cope with stress by spraying with solution of Sunshine Epi.

Enjoy the beauty of your thriving indoor tropical garden!
