How to Learn Your New Home's Landscape
You just inherited a landscape designed by people who had different taste, different time, and different priorities than you. Some of what they planted is thriving. Some is dying. Some shouldn't be there at all. Before you accidentally kill a $500 Japanese maple or let a dying shrub take the siding with it, spend a few hours learning what you actually have and how it works. This last step of the first month is the setup for a yard you understand, not just inherit.

Identify Every Plant and Tree
You can't care for what you can't name. Plant ID apps make identification easy and free.
Download iNaturalist or PlantNet
iNaturalist is free, backed by National Geographic, and uses both AI and a community of naturalists to verify identifications — it's the gold standard. PlantNet works well offline if your yard has poor cell signal. PictureThis offers a cleaner interface with care instructions for a small monthly fee.
Take three photos per unknown plant
Full plant shot, close-up of leaves (front and back), and any flowers or fruit. More context means better AI identification. For tall trees, capture the bark, the leaf shape, and the overall silhouette.
Keep a yard map with plant names
Sketch a simple top-down map of your property and label each plant by name (“Japanese maple by porch,” “Knock Out roses in south bed”). This becomes your reference when you search care instructions or hire a landscaper.
Map Irrigation Zones and Understand the Controller
If your home has an irrigation system, knowing it is essential — broken heads waste thousands of gallons and kill plants.
- Find the controller: Usually in the garage, basement, or an outdoor utility box. Note the brand and model for future manual lookup.
- Run each zone individually for 2–3 minutes: Watch outside to see which heads activate. Sketch a zone map — Zone 1 = front lawn, Zone 2 = foundation beds, etc.
- Check each head: Note head type (rotor, spray, drip) and condition. Broken or buried heads are the most common irrigation problems.
- Locate the main shut-off and backflow preventer: Main shut-off is typically near the water meter or where the irrigation line leaves the house. Backflow preventer (required to protect drinking water) is usually above-ground on the main supply line.
- Set a realistic schedule: Most lawns need 1 inch of water per week, delivered in 2–3 sessions early morning. Adjust for your climate, soil type, and plant mix.
- Consider a professional audit: $100–250 from an irrigation company will document your system, identify leaks, and optimize timing. Worth it for complex or older systems.
Track Sun, Shade, Soil, and Hardiness Zone
These environmental factors dictate what can grow where. Understanding them prevents planting failures and explains why some existing plants thrive while others struggle.
Photograph sun/shade patterns across a day
Take photos of each yard area at 9am, noon, 3pm, and 6pm on a sunny day. Full sun = 6+ hours direct light. Part sun = 3–6 hours. Shade = under 3 hours. This tells you what each spot can support.
Look up your USDA hardiness zone
Go to planthardiness.ars.usda.gov and enter your zip code. The zone (1–13) tells you which plants survive winter in your climate. Most nurseries label plants by zone — buying in-zone dramatically increases success rates.
Test soil pH and type with a $15 kit
Sold at any garden center or Amazon. Take samples from 3–4 spots in your yard. pH below 6.5 is acidic (good for blueberries, azaleas, rhododendrons); above 7.5 is alkaline (good for lilacs, lavender). Soil type — sandy, clay, loam — dictates drainage and fertility needs.
Relocate Foundation-Adjacent Plants, Plan the Bloom Calendar
Two practical actions close out your landscape learning: fix the clearly-wrong placements, and schedule the year ahead.
- Mark any plant within 3 feet of the foundation: Root growth cracks foundations over 10–20 years. Foliage against siding traps moisture. Plan relocations for the next spring or fall dormancy window.
- Note trees within 10 feet of the foundation: Have a certified arborist assess root-damage risk for mature trees. Removal costs $500–3,000 but prevents foundation repairs much higher.
- Identify invasive species: Some popular plants are invasive in certain regions (English ivy, bamboo, Bradford pear). Your state's extension service publishes invasive plant lists.
- Build a seasonal bloom and care calendar: For each plant, note when it blooms (for your enjoyment) and when it needs pruning, fertilizing, or winter protection. Add to your home maintenance calendar.
- Identify high-value plants worth protecting: A mature Japanese maple or peony is worth hundreds of dollars. Know which plants to baby; let the rest fend for themselves.
- Connect with a local master gardener program: Free help answering questions about what you have and how to care for it. Usually run through a state university extension service.
Pro Tips
- •Wait a full year before major changes: Live with the yard through all four seasons before ripping things out. Spring bulbs, late-summer perennials, and fall foliage surprises reveal themselves month by month. A hasty first-year overhaul often removes plants you'd have loved.
- •Talk to the neighbor with the nicest yard: They know the microclimate, the soil, the best local nursery, and which landscaping services are worth hiring. A 10-minute conversation saves months of trial-and-error.
- •Photograph everything in bloom for next year's reference: Spring and summer photos become documentation of what's actually in your yard. Plants you forgot about in July are surprises in March; photos keep you oriented.
- •Locate utility lines before digging: Call 811 (free nationwide) before planting anything deeper than 6 inches. Hitting a gas, water, or electric line is expensive and dangerous. The service marks underground utilities with colored flags for free.
Frequently Asked Questions
What's the best app to identify plants in my yard?
Two free apps handle 95 percent of plant ID needs. iNaturalist uses AI plus a community of naturalists to verify identifications — gold standard for accuracy. PlantNet is faster for quick ID and works offline. PictureThis offers a polished interface with care instructions for a small fee. Take three photos per plant: full plant, close-up of leaves (front and back), and flowers or fruit. For high-value trees, cross-reference with a local cooperative extension service.
How do I figure out how my irrigation system works?
Start at the controller. Turn on each zone for 2–3 minutes and walk outside to see which heads activate. Photograph or sketch a zone map. Note head type and condition. Locate the main shut-off and backflow preventer. Check the rain sensor. Look up the controller model online for the manual. For older or complex systems, an irrigation company will map and document it for $100–250.
What plants should be relocated from too close to my foundation?
Any shrub or tree within 3 feet of the foundation should be relocated or removed. Root growth causes foundation cracks over 10–20 years (willows, maples, poplars especially). Foliage against siding traps moisture and invites carpenter ants, termites, and mold. Maintain 2–3 feet of open space between any plant and the house. Move small shrubs in spring or fall dormancy. For large trees within 10 feet, have a certified arborist assess root-damage risk.
