Care of mail-order plants during hot summer

Q: I live in California and about a month ago ordered several plants from you, including fruit trees (Carambola, Mango, Avocado) and flowering trees (Xanthostemon, Adeniums, Champaca, Ylang Ylang). They were all doing well until I tried to move them into full sun, when they got leaf burn immediately. Ylang Ylang was doing great in a shade, but I repotted it from 1 gal into 3 gal and it is drooping leaves now. It has been very hot (over 100F) and dry (humidity is less than 25%). Any suggestions?

A: Hot summer can be pretty challenging time for establishing new plants. These are some guidelines to make your summer gardening more successful and rewarding.

1. You can order plants at any time, but keep your eye on your local weather forecast and try to chose cooler periods to schedule your plant shipments. Here at TopTropcals we monitor weather at destinations, and we can also delay shipment per your request until more favorable conditions.

2. During hot Summer months, many plants are still OK to ship, and to be planted, many species are heat tolerant. It's usually safe to ship most succulents, including Desert roses and Euphorbias. Some fruit trees are pretty easy too, like Loquats, Mango, Eugenias. Many flowering trees can take heat: Acacias, Clusias, Jatropha, Sausage Tree, Plumerias and many others. Check our full list of plants suitable for hot and dry conditions. Most jasmines, including Jasmine Sambac and Trachelospermum make also a safe choice for hot weather planting.

3. Use shade cloth or simply white sheets to protect young plants and new plantings from hot sun.

4. When establishing mail ordered plants during hot weather, keep them in shade for longer period of time than average recommended 1-2 weeks. Give them a chance to establish really well. In areas with low air humidity, try to create a simple mist system. It can be purchased in your local Home Depot for only $20 and set up takes only 10 minutes! It makes a big difference and can help you save many plants from hot weather stress.

5. Although it may seem that during hot weather plants need more water due to high evaporation, be careful with watering, and check soil with your finger before watering - don't water if it is still wet. Combination of "hot and wet" can be as harmful for the root system as "cold and wet" during winter. Protect root systems from overheating: covering black pots with white cloth will work. Remember when temperature is above 90F, most of plants slow down their metabolism, which means roots slow down or even stop pumping water and become more vulnerable to overwatering. For the same reason, do not hurry to step up into bigger container if roots haven't filled yet the existing pot.

Grafted fruit trees for Hawaiian gardens

Q: Aloha guys, I purchased a Diospyros digyna - Black Sapote grafted var. Black Beauty from you and am checking to make sure it will fruit by itself and not need both sexes. Also checking to see if the grafted atemoya I bought from you will fruit at sea level (where I'm at) or if I should give it to a friend who is above 1,000 so it will fruit? My grafted Maimi soursop is thriving! Looking at getting a grafted jackfruit from you all next.

A: Black sapote Black Beauty does not need a second plant to produce fruit. Grafted trees should be flowering and setting fruit right away, or sometimes on the second year.
Atemoya does not require high elevation for fruiting. It is a hybrid Annona squamosa x Annona cherimola (A. cherimola species prefers higher elevation) so Atemoya is usually is happy at sea level.
Congratulations with your Soursop! It should be really happy in your location.

As for grafted Jackfruits, this is the list of varieties we usually carry. Since many of them are very rare, they sell out quickly once we get new arrivals. If you are looking for a specific variety, I strongly recommend to add it to your wishlist (click on "Notify me when available") and you will receive email from us as soon as we have it in stock, so you will be the first one to know about it!

Our favorite Jackfruit varieties (and also hot sellers)

Black Gold
Borneo Red
Crispy
Dang Rasimi

We also suggest to get a Kwai Muk (while we still have it!) - the most delicious fruit, and it should do well in Hawaii.

🌿 Bring the Jungle Inside: Winter Survival Guide Part 2.Temperature. ❄️

Smokey the tuxedo cat checks thermometers by a cold window while Sunshine the ginger tabby relaxes near a heater holding a room thermometer showing 74 F.

Smokey: Too cold. We need more heaters so the plants feel comfortable.
Sunshine: I feel comfortable.
Smokey: You are not part of my plant collection, but I am glad you are comfortable.

🌡️ TEMPERATURE: THE TROPICAL DORMANCY LINE

In Part 1 (Winter Survival Guide: Temperature) we covered the foundation: light, placement, and acclimation. That is the survival layer.

Most tropicals stop growing below 70 to 75 F. They stay green, but their engine shuts down.

Below 70F:

  • Water intake drops.
  • Roots slow down.
  • Fertilizing becomes risky.
  • Root root becomes easy.

If you WANT your plants to grow in winter, you must take care of everything: Warmth, light, humidity, water. It all works together.

  • Aim for 75 F with bright light. Water lightly. No fertilizer.
  • Watch out for drafts. Cold windows. Door blasts. Garage entryways. Even one gust can trigger leaf drop.
  • Vents are the opposite problem: hot, dry, dusty air. That gives you crispy edges and mites.
    • Root zone temperature matters just as much as room air. Your thermostat may say 72 F, but your pot on a tile floor may be sitting at 55 F. Fix this by elevating pots on boards or stands. Use Styrofoam. Never keep pots directly on cold tile o windowsill
  • Extra winter heat: Space heaters are fine if used smartly. Do not blow hot air directly on plants. Keep heaters away from cords, trays, and water. Oil filled radiators are the safest option for plant rooms.
  • Use a humidifier if you want growth or want to prevent spider mites. But do not blow mist directly onto leaves. Always place the unit lower than the plant canopy.
  • Grouping helps. Put tropical plants close together to share humidity. Do not mix succulents with humidity lovers.
  • Cats and dogs love to knock over lights and stands. Secure your fixtures. Trust us.
  • Airflow: Light airflow is healthy. Direct fan blast is not. Still, dry corners invite mites.
  • A mild night drop is OK. A big one below 55 F will stop growth completely.

☂️ PLACEMENT: MICROCLIMATES RULE EVERYTHING

Indoors is one big tradeoff: light but cold near windows, warm but dim away from them. The winning combo is a warm room with supplemental light.

Best zones to keep plants in winter:

  • South or east windows with additional light
  • Warm living spaces
  • Bright bathrooms for natural humidity

Worst zones to keep plants in winter:

  • Behind curtains
  • Directly on windowsills
  • Near heaters or vents
  • Against cold exterior walls
  • Dark corners without supplemental lighting

💨 ACCLIMATION

Moving a plant from outdoors to indoors is a shock. Light drops. Humidity drops. Airflow stops. Soil cools. Even healthy plants may drop some leaves for a few weeks. That is normal.

Before you bring them inside:

  • Rinse foliage to remove dust and pests. We recommend Sunshine NoBug - and organic, safe solution.
  • Check for ants.
  • Trim weak branches.
  • Treat soil if fungus gnats are present.

Try to bring plants inside before the first cold front, not after. If you are reading this too late, do the prep now and expect a little leaf drop.

If you nail light and temperature, winter becomes simple. In the next mail-list we will cover watering, fertilizer timing, humidity, and other indoor tricks that keep tropicals happy till spring. Stay tuned.

✔️ WINTER INDOOR FAQ: TEMPERATURE AND PLACEMENT

Q: Why are leaves dropping only on the window side?
A: Cold glass. The room may be warm, but the glass surface can be much colder.

Q: Is a cold room OK for tropicals?
A: They may survive, but they will not grow below about 65F to 75F. When nights stay below 65F for a week, many plants enter dormancy.

Q: My room feels warm. Why is my plant still not growing?
A: Check the soil temperature. Pots on cold tile can be 10 to 20F colder than the air.

Q: Can plants sit directly on the floor?
A: Not on cold tile. Always elevate them on boards, stands, or trays.

Q: Is it OK to keep plants near a heater or vent?
A: No. Vents and heaters blast hot, dry air and cause crispy leaves and mites.

Q: My plant is dropping leaves after coming indoors. Why?
A: Normal acclimation to reduced light and humidity right after the move.

Q: Can I keep plants in a bright bathroom?
A: Yes. Bathrooms can have good humidity. Just keep pots off cold tile.

Q: Do I need a humidifier?
A: Not for survival. Yes if you want better growth and fewer pests like spider mites.

Q: Do I need a grow tent?
A: No. A bright LED plus a warm room is enough for winter holding.

Q: Should I fertilize in winter?
A: Not now. Winter fertilizer rules will be covered in the next mail-list.

Q: Should I water the same as in summer?
A: No. Indoor plants need much less water in winter. Watering rules also coming soon.

Cleanest fruit?

"Dirty" fruit: According to the Environmental Working Group research, Strawberries are top the list of the 12 "dirtiest" fruits and vegetables grown commercially. Spinach is the second, followed by (in order of contamination) nectarines, apples, grapes, peaches, cherries, pears, tomatoes, celery, potatoes and sweet bell peppers. Each of these foods tested positive for pesticide residues and contained higher concentrations of pesticides than other produce. This causes of course chronic health implications. Children are of special concern as younger bodies have greater susceptibility to pesticides than adult bodies, the report emphasizes. Pesticides may induce chronic health complications in children, including neuro- and behavioral problems, birth defects, allergies, asthma, and even cancer...

"Clean 15": Avocados lead 2018's clean fruits and veggies list, that also includes: mangoes, papayas, pineapples, kiwi, sweet corn, cabbage, onions, frozen sweet peas, asparagus, eggplant, honeydew melon, cantaloupe, cauliflower and broccoli.
Obviously, home grown fruit and vegetables are even better. Such fruit as Custard Apples, Sapodilla, Sapote, Jackfruit, Dragon Fruit, Passion Fruit and other rare varieties of tropical fruit, are even better for you because they are not grown commercially, and the choice from your own organic garden is the healthiest for yourself and your family!
Plant them today and get your cleanest fruit tomorrow!

🌿 Bring the Jungle Inside: Winter Survival Guide Part 1: Lighting ❄️

Smokey the taxedo cat adjusts an indoor grow light while Sunshine the ginger tabby sits holding a hygrometer he does not understand.

Smokey: "Winter lighting must be precise. I need this light exactly at 14 inches."
Sunshine: "Sure. I am holding this… little number thing."
Smokey: "It reads humidity. Your main job is to look cute."

🌞 LIGHT, TEMPERATURE, PLACEMENT

Winter indoors is a different kind of battlefield. Dark rooms. Dry air. Cold windows. Random drafts. Weak light. Sad plants. We've been talking about keeping your tropicals alive outdoors previously. But some of you have no choice this time of year. You have to bring the jungle inside.

If that is you, then this is your plant survival guide.

☀️ LIGHT: THE WINTER LIFELINE

Light advice here comes straight from our in-house expert, Michael Dubinovsky, a high-tech lighting engineer with over 30 years of hands-on experience. If he says brightness beats hours, trust him.

Here is the truth: Indoor light in winter is 10 to 50 times weaker than outdoors. Short days. Low-angle sun. Windows filtering half the useful light. It all adds up.

Tropicals need 10 to 12 hours of real brightness. Winter sun cannot do that on its own. Not even in a big window. So we help them.

Use bright LED shop lights or utility lights. 5000K to 6500K CCT. High lumen output. Skip decorative bulbs. Skip purple grow fancy toy lights. If you want a single plant light, even a clamp lamp is fine if you screw in a bright daylight LED bulb.

Panels work best for plant clusters. Bars for shelves. Bulbs for single plants. And grouping plants under one bright panel always beats spreading them out.

Distance matters: keep LEDs about 12 to 18 inches above the leaves. Too close: leaf burn. Too far: stretching, weak stems.

Leaves reaching up? Light is too high or too weak. Leaves curling down? Light is too close.

If you want a reality check, download any smartphone lux meter app. Most indoor corners are 50 to 200 lux without supplemental light. Tropicals want much more

And a quick tip about windows: winter sun comes in sideways. A spot that looks bright at noon can go dull by 2 PM. Don't count of window light

Bright light or long hours

People try to fix weak light by running it for 16 or 18 hours. That does not work. Plants care more about light intensity. A few hours of strong light beats all-day dim light. If the light is weak, adding more hours will not change anything except your electric bill.

Simple rule: Short duration but bright is always better than long duration but weak. - by Michael, Top Tropicals lighting expert

No need for fancy horticultural panels

You do not need purple grow lights. You do not need special horticultural fixtures. You do not need expensive panels unless you want real winter growth.

For winter plant holding till spring, the inexpensive solution works great:

  • Bright LED daylight bulbs (5000K to 6500K) from hardware store
  • High lumen output
  • Inexpensive clamp lamps
  • Aim directly at the plant from 12 to 18 inches

This setup keeps tropicals happy until spring without buying anything fancy. Save the money for soil, pots, or your next plant.

Indoor plant lighting safety note:

  • Use timers. Keep cords dry. Do not overload outlets.
  • Do not hang lights over humidifiers.
  • And do not put fixtures on piles of books to raise them. People do this.

✔️ WINTER INDOOR FAQ: TEMPERATURE AND PLACEMENT

Q: I am in Home Depot. Which light do I buy?
A: LED shop light, daylight color (5000K to 6500K), high lumens. Skip fancy plant bulbs.

Q: Can I use clamp lamps or floor lamps for plants?
A: Yes. Clamp lamps with a bright daylight LED bulb work great for winter holding.

Q: Do I need special horticultural grow lights?
A: No. A bright LED daylight bulb works fine for winter. Save the fancy lights for real growth projects.

Q: How far should the light be from the plant?
A: About 12 to 18 inches above the leaves. Too close burns. Too far stretches.

Q: Can I run weak lights for 18 hours to compensate?
A: No. Weak light plus long hours still equals a weak plant. Brightness matters more than hours.

Q: How do I know if a spot is bright enough?
A: Use a free phone lux app. Most indoor corners are much too dim for tropicals.

Q: I have a huge window. Why do I still need LEDs?
A: Indoor winter light is weak, short, and filtered by glass. Plants want intensity, not just a big window.

Q: My window faces north. Now what?
A: North windows are decorative only. Use supplemental lighting or move the plant.
