What pot is good for Medinilla?

Q: I just acquired a Medinilla plant. I have a cylindrical tall clay pot that I would like to repot this beauty into. Would like to know if a deep pot is good for this type of tropical plants even if the medium is lightweight with bark and perlite allowing adequate drainage. Would appreciate your advice.

A: Medinillas are very close to epiphytes, meaning they like high air humidity and very good soil drainage characteristics. Clay pots usually provide good air circulation, as long as they are not glazed. If you add a lot of soil conditioner into your mix, like orchid mix and perlite, the tall pot will provide a good drainage. Tall pot is also great for displaying the beautiful pendulous blooms!

Plastic pots work well too, as long as you provide a well-drained soil for the plant. If a nursery plastic pot is not pretty enough, you may place it in a fancy planter; however, make sure never let the pot sit in water, Medinillas do not like wet feet.

What Fertilizer to Use Now and How?
Five important keys to healthy plants

Sunshine  Boosters  Selection

Q: It's early Spring this year. Should I start fertilizing my plants sooner than usual?

A: Most fertilizer instructions recommend fertilizing tropical plants from March to November. This is because plants don't need as much food during the cooler months when many go dormant, and excess nutrients can burn the roots if not absorbed. However, for the most effective fertilizer program and healthy plants, consider these points:

1. Sunshine Boosters Year-Round

Liquid amino-acid-based fertilizers like Sunshine Boosters are safe to use year-round. Since watering is reduced in cooler weather, the intake of water-soluble fertilizer is also lower, providing plants with just the essential nutrients for their minimal needs.

2. Dry Fertilizer Schedule

Be cautious with dry fertilizers. Apply them only during active growth in the hot season.

3. Temperature Is Key

If March is still cold, delay dry fertilizer use. However, if nighttime temperatures in February stay above 65F, you can start a dry fertilizer program using slow-release, granulated plant food.

4. What Fertilizers to Use and How

Check out our Sunshine Boosters selection for different types of plants and choose the right type for your needs. These can be applied as often as with every watering:

For Rapid Growth
Sunshine Robusta - Rapid Growth Booster: general fertilizer for both foliage plants and small starters that need an extra boost.

For Flowers
Sunshine Megaflor - Bloom Booster: boosts flowers on established plants; and Sunshine Pikake - Fragrant Plant Booster: best for fragrant flowers.

For Fruit Trees
Sunshine C-Cibus - Crop Booster: contains all necessary elements for fruit trees and their production. Sunshine Mango Tango - specifically formulated for Mango and Avocado trees, and Sunshine Citron - ideal for citrus trees.

For Tender Perennials
Sunshine Orchidasm - Orchid Total Feed and Sunshine Ananas - Pineapple and Bromeliad Booster: mild formulas for these tender perennials.

5. Microelement Supplements Are a Must

Besides macronutrients, plants need additional microelements, just like humans need vitamins. Be sure to apply these supplements along with your regular plant food:

For Green Leaves and Health
Sunshine SuperFood - Complex Microelement Supplement: a must for healthy plants. Apply once a month.

For Stress Relief
Sunshine-Epi - Brassinosteroid Plant Hormone: essential for plants recovering from stress (shipping, transplanting, drought, insect damage, cold stress, etc.). Apply as needed.

For Sweeter, Bigger Fruit
Sunshine Honey - Fruit Sugar Booster: application on fruit trees will make fruit bigger and sweeter by directing sugars to the fruit from other plant parts, and helps to prevent bud drop. Apply 4 times a year: at bud setting, flowering, fruit setting, and after harvesting.

For Better Resistance
Sunshine Power Si - Silicon Protector - enhances resistance to insects, diseases, drought, and frost, while boosting growth. Apply once a month, along with Sunshine SuperFood.

How to get shade quickly... and stay away from oaks

TopTropicals

Q: I just moved from Tennessee into a new house in Florida and there are no trees on the property, the yard is brutal hot. What can I plant so I have some shade real quick? I like Florida shady oaks, how long will they take to grow?

A: First of all, do not rush into oak solution. Oaks are beautiful shade trees, however they have at least 2 problems:
a) Oaks are slow growers and unless you are willing to wait some 20 years... you won't get that desirable shade that quickly.
b) We have hurricanes in Florida... sometimes. A hurricane can damage any tree, however with oaks it may be the worse case scenario - the branches of those giant trees are huge, hard and heavy and in unfortunate situation when you need to remove or trim a broken tree, it may cost you... a few thousand dollars.

These are solutions that are more economical and practical:

1) Selection. If you have room, get one of these most popular Florida shade trees: Royal Poinciana, Golden Shower, Hong Kong Orchid Tree, Red Kapok, Bottlebrush, and many others. See full list of fast growing shade trees. Or simply get a Mango Tree and have delicious fruit too! Many varieties of Mangos are very large and fast growing.

2) Do it right. Even if you are planting a smaller tree, 1-3 gal size, it may become a nice shade tree within 2-3 years and start providing your driveway with desirable shade. The keys for fast growth are -
a) Good soil. Dig as big hole as possible and fill it with good rich soil containing compost. See planting instructions PDF.
b) Water. Do not rely on sprinklers and rains. Water your tree daily for the first week, then at least twice a week for another month. After that, irrigation system will be enough.
c) Fertilizer. Put a few handfuls of fertilizer in a planting hole. Then fertilize once a month during warm season. Apply micro elements for even better results and faster growth.

3) Ask experts. Contact our office for advice. We will suggest the most suitable shade tree for your yard based on features of your property: location, soil, exposure, etc.

New video: Royal Poinciana
The most beautiful tropical shade tree

"The Royal Poinciana is one of the most spectacular flowering trees in the USA, and probably among the top 10 on this planet. In full bloom, it is like a regal elephant caparisoned in red and yellow brilliance." (Larry M. Schokman, The Kampong, National Tropical Botanic Garden)
One of the most conspicuous flowering trees seen in the tropics, Royal poinciana (Delonix regia) has bright fiery red/orange blossoms cover its mimosa type leaves which close up and go to sleep for the night. This large tree, which naturally assumes a spreading umbrella shape, is now found in gardens, parks, and planted along streets throughout the tropics. In late spring, as the new leaves appear, the tree is covered with masses of five-petalled red flowers resembling orchid flowers. Blooming is followed by long, flattened, leathery dark brown or black seed pods. Delonix requires full sun and adequate space to take its characteristic form....
