Frost Dates
| Date Type | Definition | Why It Matters |
|---|
| Last spring frost | Date after which frost unlikely | When to transplant outdoors |
| First fall frost | Date of expected first frost | When to harvest or protect |
| Growing season | Days between frost dates | What you can grow |
Find your frost dates from your local extension office or farmer's almanac.
Sunlight Assessment
Track sunlight in your garden area for a full day:
| Category | Daily Sun | Best For |
|---|
| Full sun | 6+ hours | Most vegetables, fruiting plants |
| Partial sun | 4-6 hours | Greens, root vegetables, herbs |
| Partial shade | 2-4 hours | Leafy greens, some herbs |
| Full shade | Less than 2 hours | Few food plants thrive |
Note: Hot afternoon sun is more intense than morning sun.
Microclimates
| Factor | Warmer | Cooler |
|---|
| Slope | South-facing | North-facing |
| Structures | Near south walls | Open, exposed areas |
| Elevation | Low spots (heat sinks) | High, windy spots |
| Water | Near bodies of water | Away from water |
| Trees | Open areas | Under tree canopy |
Choosing a Garden Location
Ideal Characteristics
| Feature | Why |
|---|
| 6+ hours sun | Most crops need full sun |
| Near water source | Watering convenience |
| Good drainage | Prevents root rot |
| Level ground | Easier to work, even watering |
| Protected from wind | Reduces stress on plants |
| Away from trees | No root competition, more sun |
| Close to home | You'll visit more often |
Poor Locations
| Location | Problem |
|---|
| Under large trees | Shade, root competition |
| Low-lying areas | Frost pockets, waterlogging |
| Steep slopes | Erosion, difficult access |
| Near black walnut trees | Toxic to many plants |
| Far from water | Inconvenient watering |
| Heavy foot traffic | Soil compaction |
Garden Types
Raised Beds
Construction:
| Material | Lifespan | Cost | Notes |
|---|
| Cedar | 10-15 years | High | Naturally rot-resistant |
| Redwood | 15-20 years | High | Premium option |
| Pine (untreated) | 3-5 years | Low | Short-lived |
| Composite | 20+ years | High | No maintenance |
| Galvanized steel | 20+ years | Medium | Modern look, heats up |
| Concrete blocks | Permanent | Medium | Easy DIY |
Dimensions:
| Measurement | Recommendation | Reason |
|---|
| Width | 3-4 feet | Reach center from sides |
| Length | 4-12 feet | Personal preference |
| Height | 8-12 inches minimum | Adequate root depth |
| Height | 24+ inches | Wheelchair accessible |
Advantages:
- Better drainage
- Fewer weeds
- Warmer soil (earlier planting)
- No tilling needed
- Less bending
- Control over soil quality
In-Ground Beds
Best when:
- Large growing area needed
- Budget is limited
- Existing soil is decent
- You don't mind tilling/digging
Preparation:
- Mark bed boundaries
- Remove grass and weeds
- Test soil
- Add amendments as needed
- Till or double-dig
- Rake level
- Add mulch pathways
Container Gardening
Container sizes:
| Container Size | Good For |
|---|
| 1-2 gallons | Herbs, lettuce |
| 5 gallons | Peppers, small tomatoes |
| 10+ gallons | Full-size tomatoes, squash |
| Half barrel | Multiple plants, trees |
Requirements:
- Drainage holes (essential)
- Quality potting mix (not garden soil)
- More frequent watering
- Regular fertilizing
Straw Bale Gardening
| Advantage | Consideration |
|---|
| No tilling | Requires conditioning first |
| Good drainage | Needs more watering |
| Warm soil | Lasts 2-3 seasons |
| Inexpensive | May harbor wheat seeds |
Starting Your First Garden
Start Small
| Experience Level | Suggested Size |
|---|
| First year | 4x8 feet or 2-4 containers |
| Second year | 8x8 feet or add beds |
| Third year | Expand based on time available |
Beginner-Friendly Crops
