Cold protection of tropical container plants

Q: I am long time customer of yours, I live in San Diego California and while the summer and Fall temperatures are warm to mild, the winter temperatures dip to a point where some tropicals die off. We are experimenting with different variations of way to heat and insulate the pots we have the tropicals planted in as a way to keep them alive during the colder winter months. I was wondering if you knew of the ideal soil temperature for these tropical in order to look their best year round. All of the heaters we have installed have thermostats and temperature adjustments so we can now keep the soil anywhere between a range of between 65-75 degrees. Any advise you can provide would be greatly appreciated.

A: This is a very interesting concept you are working with. Indeed, keeping pots/roots warm, may help a lot! We've been experimenting with cold protection for a long time - for the above-ground plant parts. For sure keeping roots protected (even with a thick layer of mulch) will benefit tropical plants during winter. In case with container plants, this may help dramatically.
The guideline is, tropical plants slow down or stop their metabolism at 65F. As long as you can keep soil above that temperature - this should work great. Of course, the higher the better.
Optimum temperature for growing tropical plants in general - 70-85F. Above 90F, metabolism stops too, unless it's a heat tolerant, desert plant.

⭐️ Choosing the Right Variety of Jasmine Sambac

By Tatiana Anderson, Horticulture Expert at Top Tropicals

Jasmine  Sambac  varieties  collage  showing  single,  double,  and 
 multi-layered  white  fragrant  flowers  including  Belle  of  India,  Grand  Duke, 
 Arabian  Nights,  and  other 
 forms.

Jasmine Sambac varieties: Arabian Nights, Little Duke, Belle of India, Grand Duke, Duke Supreme, Maid of Orleans, Mysore Mulli, Malichat, Gundu Mallii

One of the reasons Jasmine Sambac is so fascinating is that it does not come in just one form. Each variety has its own personality.

If you want a compact patio plant, Arabian Nights or Little Duke are excellent choices. They stay tidy, bloom generously, and are easy to manage in containers.

If you prefer elegant, elongated petals and a refined look, Belle of India is a favorite. It can be grown as a small bush or trained lightly as a vine.

For those who love full, carnation-like double flowers, Grand Duke of Tuscany and Grand Duke Supreme are classic selections. They are vigorous and make impressive shrubs in warm climates.

If you need a stronger climber for fences or hedges, Maid of Orleans performs beautifully in full sun while Mysore Mulli prefers semi-shade.

Collectors often enjoy rare forms like Mali Chat or newer hybrids such as Gundu Malli, which combine traits from different lines.

How to Grow Jasmine Sambac Successfully

Sambac is not difficult, but it responds best to consistency.

Light: Full sun produces the most flowers. In very hot climates, light afternoon shade is acceptable. Indoors, place it in the brightest window available.

Soil: Use a well-draining potting mix such as Sunshine Abundance. Sambac does not like heavy, constantly wet soil.

Water: Water thoroughly, then allow the top layer to dry slightly before watering again. Reduce watering during cooler months.

Pruning: Light trimming after a bloom cycle encourages branching. More branches mean more flower buds.

Feeding: Sambac is a heavy bloomer, and fragrance takes energy. During active growth, feed regularly with a balanced fertilizer that supports flowering such as Green Magic (controlled release every 6 months) or liquid Sunshine Boosters Pikake (formulated especially for fragrant flowers) - with every watering. I prefer formulas slightly higher in potassium to encourage stronger bud formation and richer bloom cycles. Consistent feeding during warm months makes a visible difference in both flower count and intensity of scent.

With proper care, Jasmine Sambac will reward you not just with flowers, but with perfume that changes the atmosphere of your entire garden.

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!

Winter is coming tips

Reminder from Kristi, the Tropical Flower Girl

As the weather gets cooler, many of you move your potted tropical plants indoors. Please remember:
1. Leaf drop. Lower air humidity, lower light and short day may cause some leaf drop. This is normal for seasonal environment change.
2. Reduce watering as it gets cooler and darker. Under lower light and in cooler temperature, plants won't need much water; some plants go dormant and only need minimum water (so soil doesn't completely dry out). Excess water may damage roots and kill a plant in winter.
3. No dry fertilizer in winter. Active growth stops. Let the plant to go into dormancy or simply have a rest. You can continue liquid Sunshine Boosters according to regular dosage chart with every watering. Since the watering is reduced, the plants will get only as much food as needed for getting through the winter.
4. Watch for insects by inspecting leaves regularly. They may attack plants more likely in the indoor conditions. You may use organic NoBug insecticide especially for your indoor plants.

Stay Warm!
