C
Companion planting
Place crops together because the pairing may help in the actual bed.
Common mistake: A good pairing can still become a cramped mess by July.
View term ->Crop rotation
Move related crops between beds across seasons.
Common mistake: Tomatoes and peppers are different plants, but the bed remembers them as relatives.
View term ->D
Days to maturity
The estimated time a crop needs to reach harvestable size.
Common mistake: The packet number is useful. The garden may still run slower.
View term ->Direct sowing
Plant seeds directly where they will grow.
Common mistake: Moisture at the soil surface matters as much as the planting date.

Soil pH
A measure of how acidic or alkaline soil is.
Common mistake: Symptoms alone rarely prove pH is the problem.
View term ->Square foot gardening
A grid method for organizing intensive raised bed planting.
Common mistake: The grid helps with spacing, but not shade, trellises, or harvest access by itself.
View term ->Succession planting
Replace or repeat crops so beds keep producing.
Common mistake: An empty square is tempting. It still has to beat heat, frost, or both.

Trying to plan a season?
When the date on the calendar is not enough
These come up when the air feels ready, the soil does not, or a cleared bed may still have one more crop in it.
Browse related terms ->Having soil problems?
When weak growth has more than one possible cause
Yellow leaves, dry soil, soggy corners, and tired beds can look similar at first. The fix is not always the first thing you blame.
Browse related terms ->Trying to fit crops into a bed?
When a bed looks empty now but will not stay that way
Seedlings leave a lot of open soil. July plants usually have a different opinion.
Browse related terms ->Starting seeds or transplants?
When young plants are easier to hurt than they look
Seeds dry out quietly. Indoor seedlings can scorch, wilt, or stall after one rough afternoon outside.
Browse related terms ->Visual explanations
Some terms make more sense when you can see the bed.
Crop rotation
Last season influences what the same soil should grow next.
View explanation ->Succession planting
A finished crop becomes a timing question for the next one.
View explanation ->Square foot spacing
A grid helps, but mature plant size still decides the layout.
View explanation ->Mulch layers
The surface layer protects soil without burying stems.
View explanation ->Common garden term mix-ups
Some garden words sound cleaner than they behave in a real bed.
Crop rotation
Common misunderstanding: Most small gardens will not manage a perfect farm-style rotation.
More useful way to think about it: Avoid the most obvious repeats when the bed layout gives you room.
Soil pH
Common misunderstanding: A yellow leaf does not automatically mean the pH is wrong.
More useful way to think about it: Check water, drainage, nutrients, roots, weather, and pH together.
Companion planting
Common misunderstanding: Most pairings do not create dramatic benefits just because they appear on a chart.
More useful way to think about it: Look for something the pairing actually does in the bed: shade, flowers, access, or space.
Square foot gardening
Common misunderstanding: The grid will not solve trellises, shade, airflow, or picking room by itself.
More useful way to think about it: Start with the square, then let the plant size change the layout.

Common questions
What kind of gardening terms does this glossary cover?
It covers vegetable garden terms that come up around raised beds, crop timing, seed starting, soil, spacing, and seasonal work.
How should a beginner use the gardening glossary?
Start with the word that matches the problem in front of you. The other terms will make more sense once the bed gives you a reason to care about them.
