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.

The ancient soil secret that modern gardeners are finally using again…
Biochar is a lightweight, porous carbon that acts like tiny caves in the soil, holding water, air, nutrients, and microbes right where roots need them.
Made from organic wheat straw using a high-fidelity pyrolysis process, so it’s clean, stable, and built to last.
Improves soil structure, moisture balance, and microbial life without chemicals or breakdown.
Some of the best soil ever created wasn’t made in a lab — it was made thousands of years ago. Biochar doesn’t feed plants directly — it makes everything around the roots work better.

If Your Soil Could Talk, It Would Ask for This
Soil wants balance.
Roots want air and water at the same time.
Microbes want safe places to live.
Biochar gives all three a permanent home.
Real Growers. Real Organic Biochar. Real Joy.

A Repotting Revelation
I used this when repotting my plants this year, and they are ALL doing astronomically better ever since! Seller was also super kind to send some of the rice hulls that I used to top the soil on my potted citrus - I will definitely be ordering these next time, as they’re an awesome top layer to the soil. 10/10 absolutely happy with my purchase and will be a repeat customer for sure.

Why We Never Plant Without It
I never pot anything without adding biochar to my soil. Instead of posting a picture of a bag of biochar, here is a picture of a recently repotted plant thriving in it.

Organic Biochar | Bioactive Carbon | Soil Health & Moisture Retention
An Ancient Soil Secret (That Still Works Today)
Deep in the Amazon, scientists discovered patches of incredibly rich, dark soil surrounded by poor jungle dirt.
This soil is called Terra Preta, meaning “black earth.”
It wasn’t natural.
It was man-made.
Ancient Amazonian civilizations mixed charcoal, organic waste, and minerals into their soil — and it transformed infertile ground into soil so rich it’s still productive thousands of years later.
That charcoal is what we now call biochar.
Modern science confirmed what ancient farmers already knew:
carbon in this form doesn’t disappear — it builds soil for generations.
Why Most Soils Lose Their Power Over Time
Soil naturally breaks down.
Organic matter rots.
Air spaces collapse.
Nutrients wash away.
Microbes disappear.
Plants struggle because the soil loses its structure.
Biochar fixes that by adding permanent structure back into the soil — structure that doesn’t rot, dissolve, or compact.
What Makes Our Biochar Different
High-Fidelity Pyrolysis (Explained Simply)
Pyrolysis is a process where plant material is heated without oxygen.
Instead of burning into ash, the material turns into pure, stable carbon.
Think of it like slow-cooking wood in a sealed oven until only the strongest structure remains.
Our biochar is made from organic wheat straw using a carefully controlled, high-fidelity pyrolysis process.
This creates clean, stable carbon — not smoky residue or half-burnt waste.
Tiny Caves for Soil Life
Biochar is full of microscopic holes and tunnels.
These tiny spaces:
Hold water like a sponge
Trap nutrients so they don’t wash away
Give microbes safe places to live and multiply
Once microbes move in, soil becomes more active and balanced.
Water & Air Storage
Those pores hold both water and air at the same time.
That means:
Less drought stress
Better drainage
More oxygen around roots
Soil stays comfortable for plants instead of swinging between too wet and too dry.
Extremely Slow to Break Down
Because biochar is almost pure carbon, it doesn’t rot like bark, compost, or wood chips.
It stays in the soil for decades — continuing to improve structure over time.
Why This Matters for Modern Gardeners
Most soils today are tired.
Biochar restores what time takes away — structure, balance, and life.
Once it’s in the soil, it keeps working quietly in the background, season after season.
That’s why ancient soils lasted for centuries.And why this works today.

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!
