When deciding what not to plant next to a house, focus on avoiding plants that can cause structural damage, attract pests, or create drainage issues. Generally, large trees with invasive root systems, thorny bushes, and plants that require excessive moisture should be kept at a safe distance from your home’s foundation.

Why Careful Plant Selection Near Your House Matters

Choosing the right plants for your landscape is more than just an aesthetic decision. What you plant near your house can significantly impact its structural integrity, maintenance needs, and even your overall comfort. Overlooking this crucial aspect can lead to costly repairs and persistent problems down the line.

Avoiding Structural Damage: Roots and Rot

The most significant concern when planting near your home is the potential for root damage. Certain trees and shrubs develop aggressive root systems that can infiltrate and crack your foundation, underground pipes, and even your sewer lines. These roots can seek out water and nutrients, and your home’s foundation can become an unintended target.

Furthermore, plants that retain excessive moisture against your house can lead to wood rot and mold growth. This is particularly true for dense, overgrown shrubs that prevent sunlight and air circulation. This dampness can compromise siding, window frames, and the very structure of your home.

Pest Problems and Unwanted Guests

Some plants are magnets for pests and can inadvertently invite them into your home. Bushes that attract insects like aphids or scale can then provide a bridge for these pests to enter your house. Overgrown vegetation can also provide shelter for rodents and other unwanted critters, making your home a more attractive target for them.

Drainage and Foundation Issues

Improperly placed plants can also disrupt your home’s drainage system. Dense plantings can impede water flow away from your foundation, leading to water pooling. This constant moisture saturation is a primary cause of foundation damage, basement flooding, and the growth of mildew and mold.

Plants to Avoid Planting Near Your House

Understanding which plants pose the most risk is key to making informed landscaping decisions. These categories highlight common culprits and why they should be kept at a safe distance.

Large Trees with Invasive Root Systems

Trees are beautiful, but their roots can be destructive. Opt for trees that are slow-growing and have non-invasive root systems if you wish to plant them near your home.

• Considerations:
  • Root Spread: How far do the roots typically extend?
  • Water Needs: Do they require significant water that might draw moisture towards the foundation?
  • Mature Size: How large will the tree become, and will its canopy overhang your roof?

Examples of trees to avoid planting too close:

• Willows: Known for their aggressive, water-seeking roots.
• Maples: Many varieties have shallow, spreading root systems.
• Poplars and Aspens: Fast-growing with extensive root networks.
• Oaks: While majestic, their large size and root systems require ample space.

Thorny or Prickly Shrubs

While some thorny bushes can act as deterrents for intruders, they can also be a nuisance and a hazard when planted too close to walkways, doors, and windows.

• Considerations:
  • Maintenance: Pruning thorny bushes can be difficult and painful.
  • Pest Attraction: Some thorny plants can harbor certain insects.
  • Damage Potential: Thorns can scratch siding and snag clothing.

Examples of thorny plants to keep at a distance:

• Roses: While beautiful, many varieties have sharp thorns.
• Barberry: Known for its dense, thorny branches.
• Hawthorn: Features sharp spines.
• Holly: Many types have sharp, spiky leaves.

Moisture-Loving Plants and Ground Cover

Plants that require consistently damp soil can create a perpetual moisture problem right against your foundation. This can accelerate the decay of wooden structures and encourage mold.

• Considerations:
  • Water Runoff: Does the plant encourage water to pool?
  • Soil Saturation: Does it thrive in constantly wet conditions?
  • Air Circulation: Does it create a dense barrier that prevents drying?

Examples of moisture-loving plants to reconsider:

• Ferns: Many thrive in shade and damp conditions.
• Hostas: Prefer moist, shady spots.
• Certain ground covers: Dense, spreading varieties can hold moisture.

Plants That Attract Pests

Some plants are notorious for attracting insects that can then become a problem for your home.

• Considerations:
  • Sap-Sucking Insects: Do they attract aphids or scale?
  • Nectar Sources: Do they attract ants looking for sweet honeydew?

Examples of pest-attracting plants:

• Crape Myrtles: Can attract aphids, leading to sooty mold.
• Some flowering shrubs: Can be magnets for bees and other pollinators, which is generally good, but if they also attract unwanted insects, it’s a concern.

Recommended Planting Distances

A general rule of thumb is to maintain a minimum distance of 10-15 feet from your house for most trees. For shrubs, a distance of 3-5 feet is often recommended, but this can vary greatly depending on the mature size and root system of the specific plant. Always research the mature size and growth habits of any plant before placing it near your home.

Understanding Your Soil and Drainage

Before planting anything, assess your soil type and how water drains on your property. If you have clay soil that holds a lot of water, you’ll need to be even more cautious about what you plant near your foundation. Ensure that your landscaping slopes away from your house to direct water effectively.

What to Plant Instead? Safe and Beautiful Options

Instead of the problematic plants, consider these safer alternatives that enhance your home’s curb appeal without the risks.

Ornamental Grasses

These add texture and movement to your garden and typically have less aggressive root systems.

Smaller Shrubs and Perennials

Dwarf varieties of shrubs and well-behaved perennials are excellent choices for foundation plantings.

Native Plants

Researching native plants for your region is often a good strategy, as they are adapted to local conditions and may have less invasive growth habits.

### What is the ideal distance to plant a tree from a house?

The ideal distance to plant a tree from a house is generally 10 to 15 feet, especially for larger tree species. This distance helps prevent the tree’s roots from damaging the foundation or plumbing and keeps falling branches away from the roof. Always consider the mature size and root system of the specific tree.

### Can bushes damage a house foundation?

Yes, certain bushes can damage a house foundation. Aggressive root systems can infiltrate and crack the foundation, while dense, overgrown bushes that retain moisture against the house can lead to wood
