Organic or inorganic fertilizers, which is best?

A very smart article by Fedor, Mike, and Ed

Colorful garden

Q: Which one is better - organic or inorganic fertilizer?

A: When it comes to fertilizer, gardeners always wonder if one better than the other. Does a total organic fertilizer make sense for you? Is it easier to just use a cheap granular fertilizer a few times per year? You may be surprised to learn that there is one fertilizer that has advantages over both!

While organic fertilizers may be all the rage, there is the difference between Sunshine Boosters fertilizers, organic and inorganic fertilizers. Sunshine Boosters fertilizers have been especially developed to provide optimal conditions for cultivating crops in pots and greenhouses. These specialized nutrient blends are essential in order to maintain an appropriate environment for successful crop production, as they compensate for the lack of natural beneficial bacteria and nitrifying organisms which are specific to open soil cultivation.
Learn about why Sunshine Boosters is the best choice...

How to feed Poinciana tree

(and other tropical flowering trees)

Q: We purchased a Royal Poinciana tree from TopTropicals not too long ago and we gradually gave it more sun until finally we were able to plant it in direct sunlight where it's been for a week or so. Rain has been sporadic lately so I'm giving it a little bit of water every day. It seems to be doing fine. I do have a question about whether the leaves are as green as they should be? I read online that I should fertilize it with gardenia / ixoria fertilizer in March, June, and October. I looked on homedepot.com but didn't really find anything that goes by that name. Would fertilizer help? Can you suggest a fertilizer?

A: Your Poinciana tree looks pretty healthy and happy, congratulations with a great job!
Traditional (old-school) fertilizer recommendations usually suggest feeding a plant 2-3 times a year with a slow-release fertilizer. And although a plant will benefit from any fertilizer application (extra food is always good), however, for the best results, faster growth, sooner and more profuse blooming, your should use complete plant nutrition products - liquid fertilizers (see why liquid fertilizers are better than dry).
Here is an example. Some people eat a big heavy meal once a day which we all know, is not very healthy. Other people eat balanced food more frequently but in smaller portions - this is always the best way to go.
From this point, plants prefer SNACKING - frequent feeding, but with less concentrated, mild and balanced nutrients.
For your beautiful Poinciana tree (and other flowering plants), we suggest the following nutrition program:

1) SUNSHINE Megaflor - Bloom Nutrition Booster - you may use this fertilizer as frequent as with every watering, it won't burn the roots, and will provide a complete nutrition for all plant needs throughout the year. You can continue fertilizing with Megaflor even during winter time. Sunshine Megaflor will help you to keep the plant healthy, vigorous, and resistant to stress and diseases. It turns leaves green and makes the plant strong so it will start flowering sooner for you.

2) Tropical Allure - Smart-Release Booster. Apply it once a month during hot season only (in Florida - from March to November).

How to get mango trees to bloom and set fruit

Cat with mango fruit

Q: Is there any way to make a mango tree set more fruit? My mango trees bloomed like crazy last year but most of the flowers dropped and I had only a few fruit. What do I need to do to get more fruit?

A: Mango trees flower from late Winter to Spring, with the peak blooming season varying based on variety. During this time, mango trees produce hundreds of small, fragrant flowers in large panicles. A healthy mango tree can produce anywhere from 500 to 2,000 flowers per panicle. However, only a small fraction of the flowers will be successfully pollinated and develop into fruit, depending on the tree's size and health.

To support healthy flowering and fruit set, mango trees need dry weather, as excessive moisture can inhibit pollination and fruit development. During flowering period, it's important not to overwater, as the tree is less active in water uptake.

Avoid dry fertilizers during flowering since the tree is focused on reproduction rather than vegetative growth. Continue applying Sunshine Boosters Mango Tango liquid fertilizer to support the tree's overall health and vigor which will encourage fruit quantity and quality. Sunshine Boosters deliver essential nutrients in optimum amounts, proportionally to water intake.

Ensuring a dry, sunny environment and mild fertilizer Mango Tango will help the tree set fruit successfully.

Detailed Cassia and Bauhinia Care Guide

Outdoor Cassia and Bauhinia Care

  • Light: Both Cassia and Bauhinia need at least 6 hours of direct sunlight daily. Cassias handle intense heat; Bauhinias can take light afternoon shade.
  • Soil: Use loose, fast-draining soil. Mix equal parts garden soil, coarse sand, and compost.
  • Watering: Keep evenly moist but never soggy. Cassias tolerate dry spells once established; Bauhinias prefer steady moisture. Water when the top inch feels dry.
  • Feeding: For profuse flowering, feed with liquid Sunshine Boosters Megaflor that is safe to use with every watering, year around. You may also apply Green Magic controlled release fertilizer every 6 months. Bauhinias and Cassias respond quickly to feeding.
  • Pruning: After flowering, prune lightly to shape and remove dead tips. Cassias can be trimmed to shrub form; Bauhinias stay bushy with pinching.
  • Mulch: Add a 2-inch mulch layer around the base to conserve moisture and prevent weeds, but keep mulch off the trunk.
  • Cold protection: Most Cassias handle brief frost; some Bauhinias like B. acuminata and B. monandra must be sheltered below freezing. For cold nights, cover with frost cloth or move containers into shelter.
  • Dormancy: Outside of tropics, most Bauhinias drop leaves in winter for a short period of time, right before flowering and are called "semi-deciduous". Cassias stay evergreen.

Indoor or Porch Care (cool-climate growers)

  • Container: Choose a sturdy pot with several drainage holes, one size larger than the root ball. Unglazed clay or thick plastic pots work best for heat regulation. Use a light, well-drained mix such as professional soilless mix Abundance. Both Cassias and Bauhinias dislike soggy roots. Add a thin layer of coarse gravel at the bottom to improve drainage. Repot every 1–2 years in spring
  • Light: Brightest spot possible - south-facing window or heated sunroom. Supplement with a grow light if sunlight is weak.
  • Temperature: Keep potted trees in warm environment for best results. The optimum temperature for Cassias and Bauhinias is between 60–85 F, although many species can tolerate cooler temperatures. Avoid cold drafts and sudden drops.
  • Humidity: Average indoor humidity is fine; occasional misting keeps foliage glossy.
  • Watering: Water sparingly in winter when growth slows; allow the top inch to dry between waterings. Do not let roots sit in water.
  • Fertilizing: Feed with Sunshine Boosters Megaflor that is safe to use with every watering, year around, to maintain flowering indoors. You may also apply Green Magic controlled release fertilizer every 6 months.
  • Pest watch: Check undersides of leaves for aphids or whitefly. A light spray of neem oil or insecticidal soap clears them fast.

"Whether you crave golden summer fireworks or soft orchid blooms that last nearly all year, both Cassia and Bauhinia bring pure joy to the garden. 💖 Bring color that never quits."

Did you know: Fall is the best planting season — roots grow faster and you’ll have flowers by spring!
