Gardening is one of Heartopia’s most rewarding and profitable hobbies, letting you grow crops and flowers for gold, cooking, crafting, crossbreeding, and hobby progression. It unlocks early in the game, and leveling it reveals new seeds, tools, and bonuses.
1. How Gardening Hobby Works
Gardening unlocks automatically early in the tutorial when you meet Blanc, the Gardening Mentor, and get your first watering can and starter seeds. The Gardening Hobby lets you:
Grow crops like tomatoes, wheat, corn, strawberries etc.
Grow flowers to decorate or create unique colors.
Earn Gardening XP by planting, watering, and harvesting — leveling up unlocks more options.
Improve crop quality, which gives better ingredients for cooking and higher sell prices.
Sell crops for gold — gardening is excellent passive income when planned well.
2. Blanc — Your Gardening Mentor
Blanc
Blanc is the NPC who introduces and manages the Gardening and Seed Shop located near Garden Street south of the Town Center, overseeing all aspects related to crops, flowers, and seeds.
Blanc offers Gardening-related quests that reward you with seeds, tools, fertilizers, and Gardening experience, helping you level the skill faster and unlock more advanced planting options.
Items Sold By Blanc
All crop seeds and flower seeds
Fertilizers to boost growth and yield
Growth boosters for faster harvests
Planters for indoor and outdoor gardening
Watering cans
Rainbow Breeding Powder (used for advanced flower breeding)
Blanc also gives you your first watering can and starter seeds to help you get started during the Gardening tutorial.
Blanc’s Daily Routine
Blanc moves between his home and garden shop at set times.
6 AM–8 AM — Gardening at his home garden
8 AM–12 PM — Garden Shop
12 PM–1 PM — Town Square
1 PM–6 PM — Garden Shop
6 PM–8 PM — Home garden
8 PM–10 PM — Relaxing at home
Tip: You can track Blanc on the map to find him quickly.
3. How to Start Gardening 
planting seeds
Step 1 — Unlock Gardening
Complete the tutorial until you meet Blanc the gardening mentor.
Blanc gives you a watering can and starter seeds.
Gardening appears in your Hobbies list.
Step 2 — Prepare Your Garden
Access your home garden plot.
Place planters from your inventory (initial plot limit based on hobby level).
You will unlock more planters and soil tiles as you level up.
Step 3 — Buy & Plant Seeds
Visit Blanc’s Garden Shop and buy seeds.
Open inventory → select seed → place in planter (crops) or soil (flowers).
Some seeds are locked behind Gardening level requirements; level gardening to unlock them.
Step 4 — Water Daily
Water can
Equip your watering can from the Tools menu.
Tap/click each planter/flower plot to water — look for the sparkle effect.
From Garden Level 3, you can hold to water multiple plants at once.
Missing watering delays growth and lowers quality.
Watering your crops daily is essential. Without water, crops still grow, but at a lower quality and slower rate.
Note: Snow or rain may auto‑water plants but can interfere with quest recognition. If watering isn’t counting, try watering neighbor plots or waiting for the next day.
Step 5 — Harvest
Once plants reach full growth, interact to harvest.
Replant seeds right away to keep cycles going.
Harvesting gives Gardening proficiency XP and produces items for cooking/selling.
4. Fertilizer & Growth Boosters
Applying fertilizer and watering your crops allows you to increase the chance of getting higher-quality stars at harvest. As your Gardening hobby level increases, your crops naturally have better base quality chances. (better star rating = higher sell value and better food utility).
How to get Fertilizer
Buy from Blanc at the Gardening Shop (multiple types at different prices).
Basic Fertilizer ~160G
Quality Fertilizer ~450G
Top Fertilizer ~1000G
Craft at any Workbench using:
1x Timber (chop trees)
1x Weed (foraging or plucking while gardening)
Apply fertilizer right after planting for the best quality, and use growth boosters to reduce crop times.

7. How to do Flower Crossbreeding 
Crossbreeding Flowers
Crossbreeding unlocks at Gardening Level 3 and lets you create hybrid flowers and rare colors.
Buy two different colored flowers (Red + White, Red + Yellow, etc.).
Plant them adjacent (touching) in the soil.
Water daily until mature.
Look for a floating seed icon — that means a new hybrid seed spawned.
Walk over the seed to collect it and plant it to grow a new hybrid flower.
Tips
Plant up to the maximum allowed (12+ flowers, depending on level) to increase adjacency chances.
Friend watering dramatically improves chances (+10–70% chance boost).
Rainbow Breeding Powder from Blanc can guarantee a hybrid seed when used on fully mature pairs — especially useful for rare colors.
Crossbreeding Color Outcomes
The crossbreeding system isn’t purely color mixing — it’s progressive and can require multiple generations.
Basic Hybrid Colors (From Base Colors)
Start with Red, White, and Yellow flowers (base colors sold by Blanc when unlocked).
Parent Colors
Hybrid Color
Red + White
Pink
Red + Yellow
Orange
White + Yellow
Cream
Advanced & Rare Colors
Rare colors like Purple, Blue, Black, Green, etc. require multi‑step crossbreeding using previously created hybrids:
Parents
Possible Outcome
Notes
Pink + Pink
Light Pink (2★)
First-tier hybrid
Orange + Pink
Coral
Rare variant
Orange + Orange
Blue (Pansy variant)
Very rare
2★ Pink + 3★ Peach
Green
Mid‑tier hybrid (Daisy example)
Green + Green
Glowing Blue / Selene variants
Top‑tier rare
Red + Red (same species)**
Black (rare)
rare black variants via same‑color crosses
NOTE: These advanced combinations aren’t always guaranteed from one attempt — they depend on star tiers and RNG, so multiple generations and attempts may be required.
Crossbreeding success and output follow an underlying star/tier system rather than simple color math — meaning you often need to breed for higher star versions to unlock rarer output. For example:
1★ + 1★ = 2★ outcome (e.g., Red + White → Pink)
2★ + 3★ pairs yield 4★ outcomes
3★ + 4★ pairs yield 5★ outcomes
