Raised Bed Garden Planner
GardenDraft Team · June 22, 2026 · Updated October 4, 2026 · 6 min read
Raised beds look tidy, which makes them easy to overfill. The edges are clean, the soil is rich, and every empty square in April feels like wasted space. Then July arrives: tomatoes lean over the path, cucumbers shade the lettuce, and the center of the bed is too crowded to harvest.
A raised bed garden planner should solve those problems before the seedlings exist.
Draw the bed to scale first
The most important raised-bed measurement is reach. A bed you can access from both sides usually wants to stay around four feet wide. A bed against a fence or wall should be closer to two. Length is more flexible, but long beds still need paths at the ends so you do not create a shortcut through the soil.
GardenDraft starts with real bed dimensions, then places crops against that scale. You can see whether a plant fits the bed at the size it will grow to.
Use raised-bed spacing
Raised beds often use denser spacing because paths sit outside the growing area. That does not mean everything can be packed tight. It means the planner needs the right spacing model for each crop and habit:
| Crop habit | Raised-bed planning note |
|---|---|
| Trellised cucumbers | Need vertical support and shadow awareness |
| Indeterminate tomatoes | Need pruning, staking, airflow, and harvest access |
| Cut-and-come-again greens | Can sit tighter when harvested young |
| Root crops | Need even underground spacing |
| Vining squash | Usually wants its own edge or a different bed |
GardenDraft uses crop-level spacing so a bed of lettuce does not behave like a bed of tomatoes.
Plan paths and tall crops together
Paths are how you water, harvest, and notice problems, so give them real room. Tall crops belong where they will not shade the rest of the bed unless you are deliberately making afternoon shade for heat-sensitive greens.
In the Northern Hemisphere, that often means placing tall trellises and tomato rows toward the north side of the bed or garden. In hot climates, you might bend that rule on purpose. A visual planner makes the trade-off explicit.
A raised bed is also a calendar
The same bed can hold spring greens, summer basil and tomatoes, then a fall sowing of lettuce or radishes. That only works when planting dates, harvest windows, and bed space agree. GardenDraft connects the layout to a frost-aware calendar so you can see what each bed holds in spring, summer, and fall.

Frequently asked questions
- What size raised bed works best?
- Most beds should stay around four feet wide when reachable from both sides, or closer to two feet against a wall or fence. Length is flexible as long as paths keep the bed easy to reach.
- Can a raised bed planner handle square-foot spacing?
- It should. Raised beds often use denser spacing than field rows because paths sit outside the bed, so the planner needs to apply bed-style spacing rather than generic row spacing.
