How Many Seeds Should You Plant Per Hole? A Simple Seed Planting Guide

Planting the correct number of seeds per hole helps seedlings grow stronger and reduces competition for water, nutrients, and space. The ideal number depends on the seed size, germination rate, plant type, and growing method.

Why Seed Quantity Matters

Planting too many seeds in one hole can cause:

• Overcrowded seedlings
• Weak stems
• Poor airflow
• Competition for nutrients
• Difficult transplanting

Planting too few seeds can result in:

• Empty spaces if seeds fail to germinate
• Uneven plant growth

General Rule for Seeds Per Hole

Once seedlings emerge, thin weaker plants if necessary.

Seeds That Usually Need Only One Seed Per Hole

Large seeds usually have good germination rates and need more space.

Examples:

Beans

• Plant 1–2 seeds per hole.
• Thin if multiple seedlings grow too close.

Peas

• Plant 1–2 seeds per hole.
• Provide support after growth begins.

Pumpkins and Squash

• Plant 1–2 seeds per hole.
• These plants need plenty of space.

Cucumbers

• Plant 1–2 seeds per hole.
• Thin to the strongest seedling when needed.

Seeds That Benefit From Multiple Seeds Per Hole

Small seeds often have lower individual success rates.

Examples:

Lettuce

• Plant several seeds together.
• Thin seedlings as they grow.

Herbs

Examples:

• Basil
• Cilantro
• Parsley

Several seeds can be planted together and later thinned.

Flowers

Many small flower seeds are often scattered rather than planted individually.

How Many Seeds Per Hole for Vegetables?

Why Plant Extra Seeds?

Gardeners sometimes plant extra seeds because:

• Not every seed germinates.
• Young seedlings may be weak.
• It helps ensure enough plants grow.

After germination, remove weaker seedlings and keep the healthiest plant.

When Should You Thin Seedlings?

Thin seedlings when they have:

• Developed their first true leaves
• Become large enough to handle
• Started competing for space

To thin:

• Remove weaker seedlings gently.
• Avoid disturbing the roots of the strongest plant.

Seeds That Should Not Be Overcrowded

Some plants need more space from the beginning.

Avoid planting many seeds together for:

• Tomatoes
• Peppers
• Eggplants
• Large flowers
• Large herbs
• Root vegetables that need room to expand

Planting Seeds in Containers

Container planting usually requires fewer seeds because space is limited.

Examples:

Always consider the mature size of the plant, not just the seedling size.

Common Mistakes When Planting Seeds

Planting Too Many Seeds

Problem:

• Weak seedlings
• Crowded roots
• Poor growth

Solution:

• Thin seedlings early.

Planting Too Few Seeds

Problem:

• Empty spaces if germination fails

Solution:

• Plant a few extra seeds when appropriate.

Ignoring Seed Size

Problem:

• Incorrect spacing and competition

Solution:

• Adjust the number of seeds based on seed size and plant needs.

The number of seeds you plant per hole depends on the type of plant and the size of the seed. Large seeds usually need 1–2 seeds per hole, while smaller seeds can be planted in groups and thinned later.

A good approach is to plant slightly more seeds than needed, then keep the healthiest seedlings once germination occurs.

Key Takeaways

• Large seeds usually need fewer seeds per hole.
• Small seeds can be planted in groups.
• Thin extra seedlings after germination.
• Avoid overcrowding roots and leaves.
• Consider the mature size of the plant.
• Follow seed packet instructions whenever available.
