Base upgrades in Steal A Tree, the Roblox tycoon simulation created by Juice Society, govern how much fruit your farm can hold and how much money your juice sales generate. Players buy these upgrades through the shop controls located above their plot on the main garden view. The base progression system splits into three tracks: Expand Plot, Juice / Customer, and Juice Income.
Documented Base Upgrade Tiers and Costs
The three upgrade tracks handle different economic roles. Expand Plot increases your maximum planting capacity, Juice / Customer raises the amount of juice each visiting NPC buys, and Juice Income multiplies the cash earned per unit of juice sold. Documented figures from third-party community guides recorded in September 2026 provide confirmed sample tiers and prices:
| Upgrade Track | Documented Tier | Effect | Cost |
|---|---|---|---|
| Juice Income | 1.1x | Multiplies what sold juice is worth | 10,000 cash |
| Expand Plot | First expansion | Adds extra planting spots | 15,000 cash |
| Juice / Customer | 2.0x | Each NPC customer buys more juice per visit | 25,000 cash |
| Juice / Customer | 3.0x | Further raises juice purchased per customer visit | 125,000 cash |
| Expand Plot | Second expansion | Adds additional planting spots | 150,000 cash |
Existing public materials do not document maximum upgrade caps or higher-tier pricing. Because developer updates can rebalance cash values and purchase thresholds, check your in-game base interface to confirm current pricing for higher levels.
Upgrade Priority: Balancing Plot Size and Revenue
Upgrading your base requires managing your bottleneck rather than following a rigid linear checklist. Expanding your plot before you have saplings ready to plant wastes cash on empty land, while hoarding saplings without open soil wastes time and creates inventory clutter.
Keep plot expansion and sapling retrieval in step using these guidelines:
- Expand your plot only when you have saplings waiting in your inventory with nowhere to put them.
- Invest in Juice Income (10,000 cash) and Juice / Customer (25,000 cash) early to accelerate your cash flow between farm expansions.
- If NPC customer queues move smoothly and open plots remain available, focus on multiplier upgrades before saving up 150,000 cash for the second plot expansion.
Base Upgrades vs. Speed Investments
Base upgrades only generate money if you can successfully carry stolen saplings back to your plot. Patrolling gnomes in the active zone knock you down if they catch you while carrying a sapling, causing you to lose the tree with no partial recovery.
When gnome tackles repeatedly interrupt your runs, allocate your cash toward speed instead of base upgrades:
| Speed Investment | Type | Effect | Cost |
|---|---|---|---|
| Grey Trail | Trail Shop | 1.5x Speed multiplier | 1,000 cash |
| Green Trail | Trail Shop | 2.0x Speed multiplier | 25,000 cash |
| Iron Treadmill | Treadmill Upgrade | Passive training upgrade | 50,000 cash |
| Purple Trail | Trail Shop | 2.5x Speed multiplier | 100,000 cash |
| Golden Treadmill | Treadmill Upgrade | Passive training upgrade | 500,000 cash |
A balanced progression rhythm alternates between farm capacity and escape speed: buy speed when gnomes stop your sapling deliveries, and buy base upgrades when your plot is full and customers queue continuously.
How Base Upgrades Interact with the Core Economy and Quests
Selling juice to NPC customers is your entire income stream in Steal A Tree. Planted trees automatically shed fruit into your plot's FRUIT JUICE VAT, which converts fruit into sellable juice without manual input. Expand Plot establishes your income ceiling by allowing more trees to drop fruit simultaneously, while Juice / Customer and Juice Income amplify the value of every customer interaction.
Purchasing base upgrades also advances the Upgrade Master quest line. Milestones in Upgrade Master 1 and Upgrade Master 2 track the cumulative number of plot and treadmill upgrades you buy, rewarding cash, speed, and sapling progression as you build out your orchard.
Frequently Asked Questions
Where do you purchase base upgrades in Steal A Tree?
Base upgrades are purchased directly from the shop controls located above your plot in the garden view.
Which base upgrade should you purchase first?
Juice Income (1.1x at 10,000 cash) is the lowest-cost documented upgrade, making it an efficient early purchase to boost juice revenue before spending 15,000 cash on your first plot expansion.
Do base upgrades increase your movement speed?
No. Base upgrades only affect plot size, juice sale pricing, and juice volume purchased per customer. Movement speed must be trained passively on your plot's treadmill or boosted with speed multipliers from the Trail Shop.
Does expanding the plot immediately increase your income?
Expanding the plot only increases your income ceiling by adding planting slots. You must still venture into the active zone, steal saplings from gnomes, and plant them before the new plots begin producing fruit for your juice vat.
