Howden pumpkins are a classic carving variety known for their uniform shape, deep orange color, and sturdy stems. If you have ever carved a jack-o’-lantern that held up for weeks, chances are you used a Howden pumpkin. These pumpkins are the gold standard for Halloween decorations, and for good reason.
In this guide, you will learn everything about growing, selecting, and using Howden pumpkins. From planting seeds to carving the perfect face, we cover it all. Let’s get started.
What Are Howden Pumpkins
Howden pumpkins are a specific cultivar developed by John Howden in the 1960s. They were bred to have a consistent round shape, thick walls, and strong handles. This makes them ideal for carving and display.
These pumpkins typically weigh between 15 and 25 pounds. Their deep orange color is uniform, and the skin is smooth but slightly ribbed. The stem is thick and woody, which helps the pumpkin last longer after harvest.
Unlike some other varieties, Howden pumpkins are not grown for their flavor. The flesh is stringy and watery, so they are not the best choice for pies or soups. Their purpose is decoration.
Key Characteristics Of Howden Pumpkins
- Shape: Uniformly round and slightly flattened
- Color: Deep, consistent orange
- Weight: 15–25 pounds on average
- Stem: Thick, sturdy, and dark green
- Rind: Smooth with shallow ribs
- Flesh: Stringy and pale orange

How To Grow Howden Pumpkins
Growing Howden pumpkins is straightforward if you have enough space. They need full sun, rich soil, and consistent watering. Here is a step-by-step guide.
Step 1: Choose The Right Location
Pick a spot that gets at least 6 to 8 hours of direct sunlight daily. The soil should be well-draining and rich in organic matter. Avoid areas where water pools after rain.
Step 2: Prepare The Soil
Test your soil pH. Howden pumpkins prefer a pH between 6.0 and 6.8. Add compost or aged manure a few weeks before planting. This gives the plants the nutrients they need.
Step 3: Plant The Seeds
- Wait until after the last frost date in your area. Soil temperature should be at least 60°F.
- Plant seeds 1 inch deep in hills or rows. Space hills 4 to 6 feet apart.
- Plant 3 to 4 seeds per hill. Thin to the strongest 2 plants once they have true leaves.
- If using rows, space seeds 12 inches apart and thin to 24 inches between plants.
Step 4: Water And Fertilize
Water deeply once a week, providing about 1 to 2 inches of water. Avoid overhead watering to prevent powdery mildew. Use a soaker hose or drip irrigation if possible.
Fertilize with a balanced 10-10-10 fertilizer when the vines start to run. Switch to a high-phosphorus fertilizer when flowers appear to encourage fruit set.
Step 5: Manage Pests And Diseases
Common pests include squash bugs, cucumber beetles, and vine borers. Use row covers early in the season. Remove them when flowers appear so bees can pollinate.
Powdery mildew is a common disease. Plant resistant varieties if available. Space plants well to improve air circulation. Apply fungicide if needed.
Step 6: Harvest At The Right Time
Howden pumpkins are ready when the rind is hard and the stem starts to dry. The color should be deep orange. Use a sharp knife to cut the stem, leaving 3 to 4 inches attached. Do not carry the pumpkin by the stem alone; it can break.
Cure the pumpkins in a warm, dry place for 10 to 14 days. This hardens the skin and extends storage life. Store them in a cool, dark location at 50 to 55°F.
Selecting The Best Howden Pumpkins
Whether you buy them from a farm or a store, choosing the right pumpkin matters. Here is what to look for.
Check The Stem
The stem should be firm and green or brown. Avoid pumpkins with a broken or missing stem. They will rot faster. A thick stem indicates a healthy pumpkin.
Examine The Skin
Look for a uniform deep orange color. Avoid pumpkins with soft spots, cuts, or bruises. The skin should be hard and not easily punctured with your fingernail.
Feel The Weight
A good Howden pumpkin feels heavy for its size. This means it has thick walls and is full of moisture. Light pumpkins may be drying out inside.
Check The Bottom
Turn the pumpkin over. The bottom should be flat and free of rot. A flat bottom means the pumpkin will sit steady on your porch or table.
How To Carve Howden Pumpkins
Carving a Howden pumpkin is a classic fall activity. Their thick walls and sturdy shape make them perfect for detailed designs. Follow these steps for best results.
Tools You Will Need
- Carving knife or pumpkin carving kit
- Scoop or large spoon
- Marker or pen
- Pattern or stencil (optional)
- Tealight or LED candle
Step 1: Clean The Pumpkin
Wipe the outside with a damp cloth to remove dirt. Cut a hole in the bottom or top. Cutting the bottom is better because the candle sits on the ground, and the pumpkin sits over it.
Step 2: Remove The Insides
Scoop out all the seeds and stringy flesh. Scrape the walls until they are about 1 inch thick. Thinner walls let more light through but may collapse faster.
Step 3: Draw Your Design
Use a marker to draw the face or pattern on the pumpkin. If you are using a stencil, tape it on and trace the lines with a pin or knife.
Step 4: Carve Carefully
Cut along the lines with a sawing motion. Push pieces inward or outward as needed. Take your time, especially around small details.
Step 5: Light And Display
Place a candle or LED light inside. If using a real candle, make sure the pumpkin is stable and away from flammable objects. Light it at dusk for maximum effect.
To make your carved pumpkin last longer, apply petroleum jelly to the cut edges. This seals in moisture and slows decay. You can also spray the inside with a bleach solution (1 teaspoon bleach per quart of water) to prevent mold.
Storing Howden Pumpkins
Proper storage extends the life of your Howden pumpkins. Whether uncarved or carved, follow these tips.
Storing Uncarved Pumpkins
Keep them in a cool, dry place away from direct sunlight. Temperatures between 50 and 55°F are ideal. Do not store them near apples or other fruits that release ethylene gas, which speeds up ripening.
Check them weekly for soft spots. Remove any that show signs of rot to prevent it from spreading to others.
Storing Carved Pumpkins
Carved pumpkins last only a few days to a week. Keep them in a cool place overnight. You can also wrap them in plastic wrap and refrigerate them when not on display.
Spray the cut surfaces with water mixed with a little bleach daily. This keeps bacteria and mold at bay. Replace the candle or light as needed.
Common Problems With Howden Pumpkins
Even experienced growers face issues. Here are some common problems and solutions.
Poor Germination
Seeds may not sprout if the soil is too cold or too wet. Wait until the soil warms up. Plant in well-draining soil and avoid overwatering.
Small Fruit Size
If your pumpkins are smaller than expected, they may not have enough nutrients or water. Fertilize regularly and water deeply. Also, thin the fruit to one or two per vine for larger pumpkins.
Rotting On The Vine
Fruit rot is often caused by excess moisture. Elevate the pumpkins off the ground using a board or straw. Improve air circulation by pruning vines.
Pest Infestations
Squash bugs and vine borers can kill plants quickly. Inspect leaves regularly. Remove eggs and bugs by hand. Use insecticidal soap if needed.
Using Howden Pumpkins Beyond Carving
While carving is the main use, Howden pumpkins have other purposes. Here are a few ideas.
Fall Decorations
Place them on your porch with hay bales, corn stalks, and mums. Their uniform shape makes them easy to arrange. Paint them instead of carving for a longer-lasting decoration.
Compost Or Animal Feed
After Halloween, you can compost the pumpkin. It adds nutrients to the soil. You can also give it to livestock like pigs or chickens. They love the flesh and seeds.
Seed Roasting
The seeds are edible and nutritious. Rinse them, toss with oil and salt, and roast at 300°F for 20 minutes. They make a healthy snack.
