How to Drill in Clay Loam Soil Types

Flower bulbs

Bulb planter drills are used to create holes according to the planting depth requirements for bulbs. Generally, bulbs need to be planted two to three times the depth that they are tall. Measure you bulb to know how deep to drill the hole in your clay soil. Because clay soil is typically water logged and difficult to drill through, amend it in the fall using a few simple steps. Then you will be ready to plant your bulbs in your amended soil for spring and summer blooms.

Things You'll Need

• Tiller or hoe
• Compost
• Rake
• Bulb planter drill
• Manure

Instructions

1. Hand pull all weeds and other vegetation from the planting area, and till with a tiller or hoe.

2. Soak your clay loam soil with water, so that it is moist but not saturated with water.

3. Turn your clay loam soil with a garden fork, rake the area, and wait a day for it to dry.

4. Spread a 4-inch layer of compost over the area and incorporate the compost 6 inches deep into your garden bed.

5. Flatten your planting area with the back of a rake.

6. Press your bulb planter drill into the soil, and drill the correct amount of inches into the soil for the bulb you are using.

7. Place the bulb inside the hole with the roots facing down, and cover it with your amended clay loam soil.

Tips & Warnings

• Plant some of your bulbs slightly deeper to produce a longer blooming season.

• Avoid using manure that has not been leached (placed in water to remove salt), because excess salts can dehydrate your plants.
