what to put in the hole when planting tomatoes

Planting tomatoes successfully involves more than just digging a hole and dropping in a seedling. The soil environment you create directly impacts your tomato plant's health, growth, and ultimate yield. This guide will cover the best practices for preparing the planting hole and ensuring your tomatoes thrive.

Preparing the Planting Hole: Beyond Just Digging

Before you even think about your tomato seedling, focus on creating the ideal environment in the planting hole. This goes far beyond simply digging a hole large enough to accommodate the roots.

1. Soil Quality is Key

Amend Heavy Clay Soil: Clay soil can retain too much water, leading to root rot. Amend it with compost, peat moss, or other organic matter to improve drainage and aeration. This will help the roots breathe and access nutrients more easily.
Loosen Compact Soil: Even if not heavy clay, compact soil restricts root growth. Break up clods and incorporate organic matter to create a loose, crumbly texture.
Test Your Soil pH: Tomatoes prefer slightly acidic soil with a pH between 6.0 and 6.8. A soil test kit can help determine your current pH, and you can adjust it accordingly with lime (to raise pH) or sulfur (to lower pH).

2. Hole Size Matters

Dig a hole twice as wide as the root ball of your tomato seedling. This allows the roots to easily spread out and establish themselves. The depth should be such that the top of the root ball is level with the surrounding soil. Avoid planting too deep, as this can damage the plant.

3. Adding Nutrients to the Hole

While amending the overall soil is crucial, you can also add extra nutrients directly to the planting hole.

Compost: A handful of well-rotted compost provides essential nutrients and improves soil structure.
Aged Manure: Similar to compost, aged manure (not fresh!) adds organic matter and nutrients. Avoid using fresh manure, as it can burn the plant's roots.
Bone Meal: A good source of phosphorus, which is essential for strong root development and fruit production.
Mycorrhizal Fungi: These beneficial fungi colonize the roots, helping them absorb nutrients and water more efficiently.

What NOT to Put in the Hole

Just as important as what you do add is what you avoid. Certain substances can harm your tomato plants.

Fresh Manure: As mentioned earlier, fresh manure contains high concentrations of salts that can burn the roots.
Chemical Fertilizers: While they provide nutrients, chemical fertilizers can also burn roots if applied directly to the planting hole without proper dilution. It's better to use them as a side dressing later.
Wood Chips or Sawdust: These decompose slowly and can tie up nitrogen in the soil, depriving your tomato plants of this essential nutrient.

Planting Your Tomato Seedling

Once the hole is prepared, gently remove the tomato seedling from its container, being careful not to damage the roots. Place it in the hole, ensuring the top of the root ball is level with the surrounding soil. Backfill the hole with the amended soil, gently firming it around the base of the plant.

Watering and Mulching

Water deeply after planting to settle the soil around the roots. Apply a layer of mulch around the base of the plant to help retain moisture, suppress weeds, and regulate soil temperature.

Ongoing Care

Regular watering, fertilizing (avoid over-fertilizing!), and pest and disease control are essential for healthy tomato plants.

Conclusion

Planting tomatoes involves careful consideration of soil conditions and nutrient levels. By properly preparing the planting hole with the right amendments and avoiding harmful substances, you’ll set your tomato plants up for a successful growing season and a bountiful harvest. Remember, a healthy soil environment translates directly to healthy, productive tomato plants. So choose wisely what you put in that hole!
