🌞 Spring Nutrition Strategy: How to Identify and Fix Plant Nutrient Starvation

Fellow gardeners,

Spring has arrived, and plants are coming back to life. New shoots are appearing, fresh leaves are unfolding, and roots are beginning to grow actively again. As plants enter this important stage of the season, they need more than just water to support their growth. Proper nutrition is essential for strong development and healthy plants. SUNSHINE Boosters provide the balanced nutrition plants need to start the growing season strong.

A simple rule we follow in our nursery: new growth responds best to foliar feeding. When nutrients are sprayed directly on the leaves, plants can absorb them quickly and efficiently.

• Immediate action – nutrients are absorbed through the leaves and start working right away.
• No delay traveling through soil – plants do not need to wait for nutrients to move down to the roots.
• Avoids soil lockout – micronutrients can become unavailable in high pH soils, but foliar feeding bypasses this problem.
• Supports stressed plants – when roots are cold, damaged, or newly transplanted, foliar feeding helps plants recover faster.

However, sometimes plants begin to show visible nutrient deficiencies. Yellow leaves, slow growth, brown leaf edges, or distorted new leaves are often early signs that the plant is missing essential elements needed for healthy development.

These symptoms are especially common in container plants, where nutrients can be quickly depleted or become unavailable due to soil pH and watering conditions.

Use the quick reference table below to identify common nutrient-related symptoms and the recommended SUNSHINE solution to correct them.

🌿Foliar Feeding: How Much and How Often

For most plants, foliar feeding works best when applied lightly and regularly during active growth.

• Regular feeding (maintenance): Mix with tap water according to the ratio on the label. For SUNSHINE Robusta use 25 ml (5 tsp)per gallon of water and spray leaves every 5-7 days during active growth.
• Correction feeding ("medicine" dose): if plants show visible nutrient deficiencies, combine SUNSHINE Robusta with SUNSHINE Superfood and spray every 5–7 days until new growth appears healthy. All SUNSHINE Boosters products are compatible and can be mixed with water in the same sprayer.
• Best time to spray: early morning or evening when temperatures are cooler and leaves can absorb nutrients efficiently.
• Important: spray both the top and underside of leaves for maximum absorption.

How to make Mango tree fruit

Q: Hello, I have a five-year-old Lemon Meringue tree that has only given me fruit one year. It put out about 50 mangoes and has done nothing for the past three years. Do you recommend any vitamins or any of the nutrients that you guys sell to help with this for next season?

A: We've had very similar problem with our Nam Doc Mai Mango tree, fruited once and no more next year. Usually the reason is nutrients deficiency, here in Florida we have poor soils. We applied Mango-Tango tree booster and it started flowering within a couple of weeks.
Generally, Mango flowering season is over by now, however, we recommend to feed the tree starting now, during active growth season. This way it will get better established before winter and also will store away all elements necessary for triggering flowering and fruiting. So by late Fall through Winter it will be ready to flower.
Along with the fertilizer, additional micro-element supplements will be beneficial. For improving fruit quality and increasing number of flowers, we also recommend to use SUNSHINE-Honey - sugar booster

How to grow everblooming orchids?

Q: I ended up with a large collection of orchids that I was given as presents... They grow well but unfortunately after the showy blooms were gone, I don't see any more flowers, just green leaves. What do I need to do to make them bloom again? Should I fertilize them with Azalea bloom booster?

A: Orchids culture is different from garden ornamental plants. First big difference, they are epiphytes, growing in a loose bark medium rather than soil, and benefit from daily mist. Second difference is a type of fertilizer. You can not use a regular garden fertilizer on orchids, because they are very sensitive to salts. Orchids need special, acidic type of fertilizer, very mild in action.
Luckily, Sunshine Boosters formulas are exactly what orchids need! They are amino-acid based, have very mild formulas, and do not create nutrient lock up (building up salts is one of the biggest enemies of tender orchids).
A new Sunshine Boosters Orchidasm TotalFeed is scientifically balanced orchid food that contains all necessary nutrients, including micro-elements, for healthy, happy, vigorous orchids. It can be used as often as daily with every foliage spray. From our testing experience, after using Orchidasm Booster, orchids not only got happy and thriving - they also bloom more often - up to several times a year, shooting new flower spikes one after another! (while normal blooming cycle for most orchids is once a year). It gets even better - the flower display lasts twice longer!
To enjoy these beautiful flowers year around - treat them with Love, give them some Orchidasm!

Secrets of a healthy Citrus tree

Q: We planted several citrus trees in our yard - Meyer Lemon, Grapefruit and Blood Orange. The trees came from the store full of flowers and even had a few fruit, but a year after planting - no more flowers! The old leaves are green, but new growth doesn't look healthy, leaves are yellowish and have spots, maybe eaten by bugs (?), and how do we get them to fruit?

A: Citrus plants are not the easiest trees to grow; they are susceptible to various diseases, pests, and deficiencies, especially in areas with high humidity/rainfall like Florida. Fungi, viruses, leaf minors, chlorosis - this is not a complete list of citrus common problems. In commercial groves, these conditions are kept under control by using harsh chemicals on solid schedule.
For home gardeners, growing citrus trees may become a challenge. Many people don't want to use harsh chemicals on their edibles; and those who do, may not always have time to apply treatments on a professional schedule. So as much as we all love a fresh juicy orange, growing your own may become quite a pain!
Sunshine Citron TotalFeed is your simple, eco-safe solution to a healthy looking, productive citrus tree with organic fruit! Amino-acid based formula provides all necessary elements to strengthen the tree and make it resistant to possible problems.
Did you know that treatment of leaf chlorosis (yellow leaves with dark green veins), commonly treated with iron supplements, in fact requires a complex combination of nutrients - both balanced NPK and micro-elements?
Use Sunshine Citron in combination with Sunshine GreenLeaf and Sunshine SuperFood and never see yellow chlorotic leaves again!
Apply Sunshine Epi on regular basis (every 2 weeks) and help your tree boost its immune system and stay virus-free.
Add Sunshine Honey, and you will have large, juicy fruit that are much sweeter and more flavorful than those from the store! All these boosters are compatible with each other, and perfectly natural. Eat your fruit safely and enjoy...
