🏠 Ten common greenhouse mistakes and how to avoid them

    • 1. Overwatering


    It's easy to overwater in a controlled environment. Many greenhouse plants need less water than you think. Overwatering can lead to root rot, yellowing leaves, and fungal issues. Monitor soil moisture regularly and adjust watering based on the plant type, season, and current weather conditions.

    • 2. Not enough light


    Don’t block too much light - plants need full-spectrum light to thrive. Most greenhouse plants require as much light as possible to ensure healthy, vigorous growth. Lack of light causes leggy, weak plants and increases the risk of disease, pests, and fungal problems.

    • 3. Too much of sun and heat


    Greenhouses with plastic covers can trap intense heat, and during sunny afternoons, plants may get “cooked”. Direct sunlight can quickly overheat and damage foliage. Use shade cloth during the hottest months or to protect light-sensitive plants and prevent heat stress.

    • 4. Overcrowding plants


    Packing in too many plants reduces airflow, creating ideal conditions for disease and pest outbreaks. Give each plant enough space to breathe, grow, and receive light. Proper spacing also makes pest control and maintenance easier.

    • 5. Poor ventilation


    Lack of airflow leads to overheating, humidity buildup, fungal disease, and weak growth. Use fans, roof vents, or roll-up sides to improve circulation and maintain healthy growing conditions.

    • 6. Skipping pest inspections


    Greenhouses can trap pests in an ideal environment. Check plants regularly for aphids, spider mites, whiteflies, and fungus. Use systemic insecticides or organic treatments like neem oil at the first sign of trouble.

    • 7. No consistent schedule


    Inconsistent watering, feeding, and lighting can stress your plants and reduce productivity. Set a simple routine, and monitor conditions daily - even a quick walkthrough helps catch problems early.

    • 8. Neglecting temperature and humidity control


    Temperature and humidity can fluctuate dramatically between day and night. Use a thermometer (preferably with max/min memory) and a hygrometer to track conditions. Install heaters, shade cloth, misting systems, or dehumidifiers as needed.
    Modern WiFi-based sensors that monitor temperature and humidity 24/7 are convenient tools - you can keep tabs on your greenhouse right from your smartphone.

    • 9. Recycling old soil


    Avoid reusing soil from plants that died, as it may harbor root diseases or pests. Always use fresh, high-quality soil for new plantings. Don't cut corners - healthy soil is key to healthy plants.

    • 10. Dirty tools, containers, and covers


    Reusing dirty pots or tools spreads disease. Clean and disinfect containers, trays, and tools regularly. Use a diluted bleach solution to clean clear plastic or ground covers if they show mold or algae buildup.

Q: Are there any tropical plants that will do well if I order them in Winter? We just bought a house in New Jersey with a large sunroom, and I can't wait to fill it with tropical beauties! Should I wait until Spring, or do you have something for a Winter start?

A: This is indeed a very good question, as many tropical plant collectors grow their treasures outside the tropics. The short answer is - yes! You can start filling your tropical sunroom any time of the year, but some plants are easier to deal with in Winter than others. Below are some guidelines.

Winter bloomers: Jatropha, Champaka, Brunfelsia, Calliandra, Leonotis

Winter bloomers today, left to right: Jatropha, Champaka, Brunfelsia, Calliandra, Leonotis.

1. Plants that prefer Winter shipping to avoid overheating stress:
- All plants with lush foliage such as Philodendrons, Medinilla
- Trees with fine feathery leaves such as Moringa, Jacaranda, Poinciana
- Some fruit trees sensitive to overheating during shipping: Papaya, Stawberry Tree, Starfruit (Carambola), Bilimbi.

2. Subtropical plants that are relatively cold hardy
- Fruit trees: Loquats, Olives, Avocados, Tropical Cherries: Eugenia, Malpighia, Noni (more cold hardy than you may think), Canistel.
- Flowering trees: Champaka, Tabebuia.
- All Bananas
- see all relatively cold hardy plants

3. Winter-dormant and/or deciduous plants: Adeniums, Plumerias, Gingers, Sugar Apple , Peaches and Plums, June Plum and Hog Plum.
See all deciduous/winter dormant plants.

4. Orchids, including Ground Orchids.

5. Winter flowers. Keep in mind that many tropical plants are winter bloomers, and their flowering is most profuse in Winter months, so you can enjoy the blooms right away:
Dombeya, Thunbergia, Gloxinia, Brunfelsia, Calliandra, Tibouchina, Barleria, Leonotis, Clerodendrums, Chinese Hat (Holmskioldia).
See all Winter bloomers.

Winter bloomers: Clerodendrum minahasse, Malvaviscus Summer Snow, Kopsia fruticosa

6. Winter plant care. During Winter the daylight is shorter and temperatures are cooler.
- Reduce watering
- Use only liquid amino-acid based fertilizer Sunshine Boosters (safe to use year around)
- Monitor insects.

7. Shipping in Winter. We ship year around. However, if it gets below freezing in your area, you may use FedEx Hold location, they are temperature controlled so you don't have to worry about a box being dropped off at your cold porch outside.

8. A note for mild climate residents. Most tropical plants can be planted in the ground year around. Some ultra-tropical tender species such Chocolate tree, Ylang Ylang, or small size Mango trees can be grown in pots until Spring and planted out once chances of cold spell are gone. Until then, they can be moved indoors for cold nights.

Think outside the box and bring tropical paradise indoors during the time when we need warmth the most! Tropical plants will brighten your short winter days and help you to have truly HAPPY HOLIDAYS!

How to move plants from indoors to outdoors

Q: When moving my tropical plant collection outside in the garden, what do I need to know to get them adjusted to this change?

A: As a tropical plant gardener, it's important to assess the temperatures outside before moving your plants outdoors. Most tropical plants thrive in sustained temperatures above 60F.
Moving your plants outside during the summer creates optimal growing conditions for sun-loving plants, providing them with more light and warmth than they can ever get inside. This active time of growth, along with the outdoor conditions of humidity, heat, sunlight, and natural day length, gives the plant a chance to experience growth in an outdoor environment, making for a much stronger plant.
However, be aware of sun burn. Direct sunlight can burn patches of white or brown on the surface of the tender leaves, so it's best to move your plants outside by hardening them off first. Gradually increase the amount of direct sunlight they receive over several days before moving them into full sun.
It's also a good time to prune your plants and repot them if needed, providing better aeration to the root system. But avoid root pruning as it can make your plant susceptible to disease and shock.
Overall, moving your tropical plants outside encourages their natural bloom cycle and provides extra vigor for the upcoming indoor season. However, be aware that you may have to deal with insects when you bring your plants back inside in the fall, so use preventive sprays like Sunshine NoBug before bringing them back inside. Leaf drop is also common when plants come back inside, so make sure to provide a well-lit location.
When moving plants outside, it's important to provide them with proper nutrients through fertilization. Outdoor conditions can deplete the soil of essential nutrients, so giving your plants a boost of fertilizer before moving them outside can help them acclimate to their new environment. Apply Sunshine Boosters with every watering, include micro-elements and bio stimulants to boost their immune system.

When plants are ready for a meal?

Q: We have an early Spring here in Florida. All plants in my garden flushing out new leaves and buds opening. Can I start fertilizing? I have Mango, Avocado, Peach trees, many medicinal herbs and flowering shrubs: Angel trumpets, plumerias, bromeliads. I prefer mild organic fertilizers; can you suggest something that is safe for edibles and butterflies?

Q: As a rule of thumb, tropical gardeners start regular fertilizing when the minimum temperatures (at night) go above 65F. Keep in mind that Sunshine Boosters fertilizers can be applied year around because they have mild formulas and used with every watering; during cooler period, you water less frequently, so feeding is reduced accordingly. Another advantage of Sunshine Boosters - they are natural (derived from organic amino acids which is the basics of Life). They are safe for edibles as well as pollinating insects.

Here is the feeding plan for your plants:
1. The most universal solution for all plants (both potted and in-ground): get a complete set of Sunshine Boosters Pro system: Advantage-Pro for vegetative growth, BloomBoom Pro for flowering stage, and Ca-Support-Pro + Constanta-Pro as necessary daily supplements. You will need all these 4 components for your garden.
2. Start adding these liquid boosters with every watering according to dozing directions and you will notice amazing growth boost within a week.
3. Apply Sunshine Epi plant hormone every 2 weeks as a foliar spray to boost immune system and metabolism of plants and protect them from diseases. Epi makes plants (especially young plants and those "waking up" from dormancy) grow twice faster! It also enhances effect of fertilizers by increasing plant metabolism.
4. After cool winter temperatures, some plants may develop element deficiencies like chlorosis (yellowing leaves). Additional microelement boost can be provided with Sunshine Greenleaf (iron supplement) and Sunshine Superfood (micro-elements).
5. For additional boosting of flowering and setting fruit, use the following individual boosters:
Sunshine Robusta - for foliage plants and when you need rapid vegetative growth
Sunshine TotalFeed - for Plumerias and other fragrant plants
Sunshine Megaflor - for Brugmansias and other flowering heavy feeders
Sunshine C-Cibus - for improving fruit production and quality
Sunshine Honey - for sweeter fruit (must be applied 4-5 times a year)
6. For young/small plants (seedlings, rooted cuttings) as well as tender tropicals like bromeliads, and orchids - Sunshine Bombino is a perfect choice due to its mild formula.
7. To save money, order complete sets rather than individual boosters; you will be able to safe up to 40%! Sunshine Complete Nutrition System Kits: Combo Kit, and Pro Kit.

If you are a fan of organic gardening, do not use dry fertilizers. While water-soluble and granulated (smart-realease) fertilizers are popular choice in plant nurseries due to their convenience, they are not as safe as liquid boosters because they create salt build-up in soil and have a high risk of overdosing/burning plant roots, especially potted plants, plants at breaking dormancy, at establishing, and at early stages of plant development. Besides, dry fertilizers may affect the taste of your fruit and herbs. See advantages of liquid boosters over dry fertilizers.

Spring is coming, plants need food! Time to fertilize...

Last winter was long and snowy in the most part of our country. Hold on fellow gardeners up North, it is almost over!
Here in Florida we have been blessed again with a mild winter without serious cold snaps. Early Spring that is already in the air. Look at this picture of flowers in our front yard now.
If the weather is already warm in your area (low temperatures above 55), it is time to start fertilizing. We are sending our love and support to tropical Puerto Rico suffered from hurricane last year, and will be happy to help you guys to restore your lost gardens!

CHECK LIST

what to do to give your garden a good kick start:

1. Slow release granulated food. Apply Slow Release Fertilizer and continue once a month. 1 tsp per gallon of pot, or a handful for in-ground plants. This will provide essential macro elements (NPK) required for a plant growth.

2. Water soluble micro-elements. Besides macro-elements, plants need many other elements that most of the time missing in soil. A lack of micro-elements causes different deficiencies, resulting in weak root systems, slow growth, deformed leaves, leaves yellowing, lack or no flowers/fruit. Apply these supplements as a foliar spray once a month to induce healthy growth and flower/fruit development. We recommend the following micro-element products to keep your plants healthy and vigorous year round:
a) SUNSHINE SuperFood - plant health booster. This revolutionary new liquid complex contains ALL microelements needed and can fix all possible problems occuring to your tropical plants - from roots to flowers and fruit. We have convenient dropper bottles of 5 ml for small plant collections, 50 ml for larger gardens, and 100 ml for professional landscape applications.
b) SUNSHINE-Micro - Microelement booster - for common iron deficiency (pale leaves)
c) SUNSHINE-Super-Iron - Microelement booster - for severe iron deficiency (severe yellowing leaves)

3. SUNSHINE plant boosters - SUNSHINE-E, -BC (caudex plants and bonsai), -H (house plants). Apply these natural plant stimulants to help plants recover from cold, dormancy, increase plant's metabolism and make a plant more readily absorb both Macro- and Micro-elements. SUNSHINE boosters also will help plants grow vigorously, withstand Summer heat and drought, and produce bigger and better flowers and fruit.

4. Kickstart a sweeter fruit. To get a better and sweeter crop in Summer and Fall, you need to start first application now. SUNSHINE Honey - is natural, Amber-colored, honey-like liquid microelement product for fruiting and edible plants that will make them sweeter, tastier and more flavorful! Very effective for tropical fruits, tubers, vegetables.
