How to transplant Jack-in-the-Pulpit safely

Understanding Jack-in-the-Pulpit (Arisaema triphyllum)

Jack-in-the-Pulpit, scientifically known as Arisaema triphyllum, is a captivating native woodland perennial that adds a unique architectural element to shady gardens. Its distinctive spathe (the hooded leaf-like structure) and spadix (the central finger-like stalk) create a charming “jack” peeking out of a “pulpit.” This plant thrives in moist, humus-rich soil and dappled shade, often found alongside ferns, hostas, and other shade-loving companions.

Successfully transplanting Jack-in-the-Pulpit requires careful timing and a gentle approach. These plants are not as robust as some common garden varieties and can be sensitive to disturbance. By understanding their natural habitat and needs, you can ensure a smooth transition for your plants, whether you’re moving them within your garden or relocating them from a wild setting (with proper permissions, of course).

Why Transplant Jack-in-the-Pulpit?

There are several compelling reasons why you might consider transplanting your Jack-in-the-Pulpit:

• Garden Redesign: As your garden evolves, you may need to move plants to better suit new design plans, create a more cohesive aesthetic, or make space for new additions.
• Improved Growing Conditions: If your current location doesn’t offer the ideal dappled shade and moist, well-drained soil, transplanting to a more suitable spot can significantly improve the plant’s health and vigor.
• Naturalization: If you’ve found Jack-in-the-Pulpit growing naturally (and have the landowner’s permission), transplanting a few specimens can bring the charm of the woodland to your own garden.
• Propagation: While not directly a reason for transplanting an existing plant, understanding its growth cycle is crucial if you’re collecting seeds or offsets from a mature plant to establish new ones elsewhere.
• Pest or Disease Management: In rare cases, if a plant is suffering from localized pest or disease issues, moving it can help isolate the problem and provide it with a fresh start.

Key Facts About Jack-in-the-Pulpit

Before diving into the transplanting process, it’s beneficial to familiarize yourself with some essential facts about this fascinating plant.

When is the Best Time to Transplant Jack-in-the-Pulpit?

The timing of your transplant is crucial for the success of Jack-in-the-Pulpit. These plants have a distinct life cycle, including a period of dormancy, which makes certain times of the year much more favorable for moving them.

The Dormant Season Advantage

The absolute best time to transplant Jack-in-the-Pulpit is during its dormant period. This means the plant is not actively growing and is less likely to suffer from transplant shock.

• Late Fall: After the foliage has completely yellowed and died back in the fall, the plant’s energy has retreated to the corm (underground storage organ). This is an ideal time to move them. The soil is typically still workable, and the plant has ample time to establish its roots before winter sets in.
• Early Spring: As soon as the ground thaws and before any new growth emerges, early spring is also a good window. However, be very careful not to disturb any emerging shoots, as these are delicate. The risk here is that you might miss the exact moment of emergence and inadvertently damage new growth.

Why Avoid the Growing Season?

Transplanting during the active growing season (spring and summer) is generally discouraged for Jack-in-the-Pulpit.

• Transplant Shock: During active growth, the plant is expending a lot of energy on producing leaves, flowers, and potentially fruit. Disturbing its root system at this time can lead to significant stress and transplant shock, making it difficult for the plant to recover.
• Drying Out: Actively growing plants require more moisture. If the roots are damaged during transplanting, they may struggle to absorb enough water, leading to wilting and potential desiccation, especially in warmer weather.

Preparing for the Transplant

Proper preparation before you even dig up the plant will significantly increase your chances of success.

Site Selection for the New Location

Choosing the right spot for your transplanted Jack-in-the-Pulpit is paramount. Replicate its preferred conditions as closely as possible.

• Shade: Look for an area that receives dappled sunlight or partial shade. Morning sun with afternoon shade is often ideal. Avoid locations with intense, direct afternoon sun, as this can scorch the leaves.
• Moisture: The soil should be consistently moist but not waterlogged. Areas near a reliable water source, such as a stream bank, or a spot where you can ensure consistent watering will be beneficial.
• Soil Quality: Amend the soil with plenty of organic matter like compost, leaf mold, or well-rotted manure. Jack-in-the-Pulpit prefers rich, humusy soil that drains well. If your soil is heavy clay, incorporating sand and organic matter will improve drainage.
• Competition: While they grow in woodlands with competition, avoid planting them in areas with aggressive, shallow-rooted plants that might outcompete them for water and nutrients in their establishment phase.

Gathering Your Tools and Supplies

Having all your equipment ready will make the transplanting process smoother and less stressful for both you and the plant.

• Gardening Gloves: Protect your hands, especially if you have sensitive skin.
• Trowel or Small Spade: For carefully excavating the plant. A hori-hori knife can also be very useful for its versatility in digging and cutting.
• Sharp Knife or Pruners: To trim any damaged roots.
• Wheelbarrow or Bucket: To transport the plant and any necessary amendments.
• Watering Can or Hose with a Gentle Nozzle: For watering the new location and the transplanted plant.
• Mulch: Such as shredded bark, compost, or leaf mold, to help retain moisture and suppress weeds.
• Compost or Organic Matter: To amend the planting hole.

The Transplanting Process: Step-by-Step

With preparation complete, it’s time to carefully move your Jack-in-the-Pulpit.

Step 1: Excavating the Existing Plant

This is a critical step that requires a delicate touch.

1. Soak the Soil (Optional but Recommended): If the soil is dry, water the area around the Jack-in-the-Pulpit thoroughly a day or two before transplanting. This will make the soil easier to work with and help keep the root ball intact.
2. Dig a Wide Circle: Using your trowel or spade, carefully dig a wide circle around the plant. Aim to go at least 6-8 inches away from the visible base of the plant to encompass as much of the root system as possible.
3. Dig Deep: Dig down, undercutting the plant to loosen the entire root ball. The goal is to lift the plant with as much of its original soil attached as possible.
4. Gently Lift: Once you’ve undercut the root ball, carefully try to lift the entire clump. You may need to gently wiggle it to loosen it from the surrounding soil. If the plant is very deep, you might need to dig further.
5. Handle by the Root Ball: Avoid pulling the plant by the stem. Instead, support it by the root ball.

Step 2: Preparing the New Planting Hole

While you have the plant carefully lifted, prepare its new home.

1. Dig a Hole of Appropriate Size: The hole should be at least twice as wide as the root ball and about as deep.
2. Amend the Soil: Mix the soil you removed from the hole with a generous amount of compost or other organic matter. This enriched soil will provide the nutrients and structure the plant needs.
3. Ensure Good Drainage: If you have heavy clay soil, you may want to add some coarse sand or grit to the amended soil to improve drainage.

Step 3: Planting the Jack-in-the-Pulpit

Now it’s time to place the plant in its new location.

1. Place the Plant: Carefully lower the Jack-in-the-Pulpit into the prepared hole. The top of the root ball should be level with or slightly below the surrounding soil surface.
2. Backfill the Hole: Gently fill the hole with the amended soil, lightly firming it around the root ball to eliminate air pockets.
3. Water Thoroughly: Water the newly planted Jack-in-the-Pulpit deeply. This helps settle the soil and ensures good contact between the roots and the surrounding soil.

Step 4: Post-Transplant Care

The care you provide immediately after transplanting is crucial for recovery.

• Mulch: Apply a layer of organic mulch around the base of the plant, keeping it a few inches away from the stem. Mulch helps retain soil moisture, regulate soil temperature, and suppress weeds.
• Water Consistently: Keep the soil consistently moist for the first few weeks after transplanting. Avoid letting it dry out completely.
• Monitor for Stress: Keep an eye on the plant for signs of wilting or stress. If it appears stressed, ensure it has adequate moisture and shade.
• Avoid Fertilizing Immediately: Refrain from fertilizing the plant right after transplanting. Allow it time to recover and establish its roots before providing any additional nutrients.

Troubleshooting and Tips for Success

Even with the best intentions, you might encounter challenges. Here are some tips to maximize your success.

Common Issues and Solutions

• Wilting: This is the most common sign of transplant shock. Ensure the plant is receiving adequate water and is in a shaded location. Avoid excessive sun exposure.
• Failure to Emerge in Spring: If you transplanted in the fall and it doesn’t appear in spring, it might be due to transplant shock, improper planting depth, or the corm not being viable. Be patient; sometimes, they take a year to establish and might not show themselves in the first season.
• Root Damage: If you suspect significant root damage during excavation, be extra diligent with watering and consider providing a temporary light shade cover if the weather is hot.

Pros and Cons of Transplanting Jack-in-the-Pulpit
