Shipping and Orders
Q: Are there any restrictions on shipping citrus?
We CANNOT ship to California, Florida, Arizona, or Louisiana. Once a tree leaves Texas, it cannot come back due to plant disease protocols.
Q: When will my citrus tree ship?
We will try to ship your tree within 1-2 business days after your order, and you’ll receive a tracking number via email once it's on the way. If the weather is bad en route, we will hold your order.
Your New Tree FAQs
Q: What supplies will I need when the tree arrives?
You’ll need a pot with drainage (at least 5 gallons if repotting), Super Soil or other well-draining soil, and water to get started!
Q: Can I keep the tree in the pot it comes in?
Yes, if you don’t have any supplies and you aren’t ready to repot, you can keep your tree in the container it ships in for a few months.
Q: How do I keep it alive when it arrives?
Simple steps:
• Unbox immediately
• Place the tree in partial shade for the first few days. Protect from any cold weather under 50°F.
• Water thoroughly (until it drains out the bottom) daily for two weeks.
• Then move to a sunny spot (6–8 hours of direct light)
Follow the quick-start guide included in your box!
Q: Will I receive care instructions with my tree?
Yes! Every order includes our printed Quick Start Guide, and you’ll also receive a digital full care guide by email. This walks you through watering, soil, pests, pruning, fertilizing, and more. No guesswork required.
Q: What's the white coating on the bottom of the trunk of my tree?
That white oil is applied to help you visually identify the grafting junction. It’s completely safe and made with natural oils. You don’t need to reapply it unless you want to, but it’s helpful for maintenance and spotting sucker growth.
Q: My tree came with a black straw on the trunk—what is that for?
The black straw is a physical barrier to help suppress rootstock sucker growth below the graft junction. It also makes the graft junction easier to find. The straw will naturally fall off as the trunk thickens, but you can remove and replace it if needed (especially during pest treatments).
Q: What will my tree look like when it arrives?
Your tree will be:
• ~12" tall or taller, depending on variety and season
• Healthy, pruned, and grafted
• May have young leaves, flowers, or baby fruit, depending on the season
Don’t worry if it looks a little sleepy—shipping stress is normal. It will perk up quickly with water and sunlight.
Q: How fast will it grow?
Most customers see noticeable growth within weeks, and see fruit in 24 months, depending on variety and care. We use Dr. Mani's micro-budding method to ensure early fruiting and strong root systems.
Q: Is this tree guaranteed?
Yes. We guarantee your tree arrives alive and healthy, or we’ll replace it. Just follow the included care steps and contact us within 30 days if there’s an issue. We’re here to help!
Is This Tree Grafted?
Q: Are your citrus trees grafted?
Yes, all our citrus trees are professionally grafted, using Dr. Mani Skaria’s proprietary micro-budding method for faster fruiting and stronger resistance.
Q: Why shouldn’t I grow citrus from seed?
Seed-grown trees take 6–8 years (or more) to fruit and may not produce quality fruit at all. Grafting clones the genetics of a proven "mother tree" with great taste, production, and resilience.
Q: Are your trees on dwarfing rootstock?
No, our trees are on vigorous and hearty rootstock — mostly Brazilian Sour Orange or Volkamer Lemon.
Q: My grafted tree lost all its leaves after cold exposure but came back lanky. Is that normal?
That new lanky growth may be coming from the rootstock. Check where it’s growing from. If it’s below the graft junction or has very different leaves, it's likely rootstock growth and should be removed.
Q: What’s the difference between sucker growth and regular branches?
Suckers grow below the graft junction (usually from the rootstock) and don’t produce edible fruit. They often grow fast and straight, with different leaves than the grafted variety. Always prune suckers to redirect energy to the grafted top.

A natural, chemical-free way to control crawling insects and surface pests
Organic Diatomaceous Earth creates a dry, abrasive surface that crawling insects and pests avoid.
When applied in water, it coats leaves, stems, and soil surfaces evenly without harsh chemicals.
Works even better when used with micronized sulfur and a small amount of Castile soap so it stays where pests travel.
Many garden pests don’t live in the soil — they crawl across it.Diatomaceous Earth helps control pests naturally — without relying on synthetic pesticides.

The Pests This Helps Control
Diatomaceous Earth is especially useful against crawling and surface-dwelling pests, including:
Ants
Earwigs
Sowbugs and pill bugs
Thrips
Fungus gnat adults
Spider mites (surface activity)
Beetle larvae
Other soft-bodied crawling insects
It works best on juvenile and active pests moving across plant surfaces, not buried deep in the soil.

How DE Works (Simple Explanation)
Diatomaceous Earth is made from fossilized microscopic organisms, diatoms encased in silica.
Those fossils form an extremely fine mineral powder with tiny sharp edges.
When insects crawl across treated surfaces:
The abrasive texture damages their outer coating
Moisture is lost
Movement becomes difficult
The result is fewer pests — without chemical action.
Why DE Works Best Applied in Water
Applying DE in water:
Reduces airborne dust
Allows even coating of leaves and stems
Helps it reach pest travel paths
Improves coverage on soil surfaces
Once the water dries, the DE remains in place and begins working.
Using on Houseplants (Important)
DE is safe for plants but dusty when dry.
For houseplants, take plants outside, apply outdoors, allow to dry, then bring plants back indoors.
How to Use It (Best Practice)
Apply DE in water, not as a dry dust.
Per 1 gallon of water, mix:
2–3 oz Organic Diatomaceous Earth
Optional:
Micronized sulfur (per sulfur instructions)
1–2 oz Castile soap for better adhesion
Shake well before and during spraying.
Spray:
Soil surface
Stems
Leaf undersides
Areas where pests crawl or gather
Apply early morning or evening.
When to Apply for Best Results
DE works best when pests are active and moving.
Apply at first sign of crawling insects
Reapply every 7 days
Reapply after heavy rain or watering
Regular application keeps pest pressure low.
What to Expect (Honest Results)
Micronized sulfur is not a chemical knock-down spray.
What it does:
Reduces pest populations steadily
Breaks pest life cycles
Helps prevent reinfestation
Protects plants without harsh residues
Warning — this product obviously smells like…sulfur!
Why It Works Even Better with Sulfur and Soap
With Micronized Sulfur
Sulfur makes plant surfaces undesirable.
DE adds physical abrasion that pests struggle to cross.
Together, they create a surface pests avoid.
With Castile Soap
Adding 1–2 oz of Castile soap per gallon helps the mixture stick to leaves and stems instead of washing off too quickly.
This improves effectiveness without harming plants.

Dear Garden Lover,
You may have tried and given up before.
Citrus trees and gardens looking tired, drooping leaves, yellow fruit. You carefully water and fertilize… but everything still struggles.
Let me tell you the truth…It’s not your fault.
Want to know the dirty little secret that I found out?
We’ve all been lied to!
The gardening world is full of products that look fancy… but are actually a net negative.
The Big Chemical companies sell fertilizers are loaded with salts that burn your roots. The Big Box stores stock potting mixes that are decomposing rot that choke your plants, and absolutely everything is lacking beneficial bacteria and fungi!
And even though I invented micro-budding, founded the clean citrus program in Texas, and had all the academic credentials, I still had to experience this pain myself!
My own trees suffered until I discovered what truly matters…the Three Plant Pillars that every plant needs to thrive:
1. Live microbes that unlock nutrients and boost roots
2. Organic fertilizer that feeds, not burns
3. Mineral-based soil that lets roots breathe
That’s why I created Plant Super Boost, Crab, Kelp & Amino Acids (7-4-4), and Super Soil.
To give trees real power. From the roots on up, everything you need and nothing you don’t. Perfected on thousands of plants of every kind.
And if you’ve got one of our micro-budded trees in your hands, know this:
You’re holding science, care, and a little Texas magic.
And you don’t have a brown thumb...you just need the right tools and the right information!
