What Does “Days to Harvest” Mean?

Have you ever looked at a packet of pepper seeds or a live pepper plant label and noticed the phrase “days to harvest” followed by a number? If you’re new to growing peppers, this number might seem confusing, but it’s an important detail you shouldn’t overlook.

Days to harvest gives growers an estimate of how long it may take for peppers to reach maturity and be ready for picking. While helpful, this number is only an average and can vary based on growing conditions, climate, and planting method.

However, keep in mind, the days to harvest is just an average estimate. These numbers generally fluctuate depending on many influential factors to the plant and its environment.

What Does Days to Harvest Mean?

As mentioned before, days to harvest refers to the pepper’s anticipated timeline from planting until you can start picking ripened peppers.

The term days to harvest takes on different meanings depending on which form.

• Pepper seeds planted in the ground, the days to harvest means from seeding to maturity.
• Pepper seedlings started indoors, the term starts from the time of transplanting to a pot or garden to maturity.

Another phrase, days to maturity, can also be found on pepper product labels. Both days to harvest and days to maturity mean the same thing and are used interchangeably with different pepper products.

Why Is Days to Harvest Important to Know?

Besides being a number that lets you know, for example, when to harvest banana peppers or when to harvest bell peppers, gardeners use days to harvest to know how long they can grow certain peppers outdoors. This knowledge is useful for a couple of different reasons: 

Growing Season

• Growing seasons are calculated in different ways, but according to the USDA, it’s the time between the last frost in the spring and the first severe frost in the fall. If you live in places that have shorter growing seasons, then you might want to start growing pepper plants indoors before you can move them outside.
• Pepper plants that grow beyond the actual growing season can be killed off by drops in temperature, air moisture, soil moisture, and the changing weather patterns that come with autumn.

Planting Multiple Peppers

• Days to harvest also lets gardeners know how many peppers they can grow within that timeframe.
• Some peppers have shorter maturity times than others; for example, harvesting jalapeno peppers can happen sooner than harvesting Thai chili peppers.
• Gardeners use days to harvest to help plan what they will grow ahead of the season and if there will be any overlapping peppers growing simultaneously.

Factors Influencing a Pepper's Days to Harvest

1. Plant Hardiness Zone

The Plant Hardiness Zone map provided by the USDA gives gardeners and farmers an idea of which plants are best to grow in their given region. Not all plants grow in every climate of the country, so it’s important for gardeners to know which plants to grow based on their location.

For pepper plants, you want to know when the last frost date is for your specific region. The further north you live, the shorter your growing season will be. Keep in mind: you should always keep up with the weather as these dates aren’t guaranteed.

2. Weather

Speaking of weather, it plays a huge factor in growing pepper plants.

• Temperature fluctuations (low or high temps) affect how the plants flower. The flowers are what produce the fruit, so if your pepper plants are experiencing heat waves or cooler weather while in the flowering process, this can stunt their growth and produce fewer peppers than anticipated.
  • Ideally, you want your pepper plants to grow in temperatures between 70-85 degrees Fahrenheit.

• Hours of Sunlight your region gets also plays a role in how long it will take until your peppers are ripe for picking. In general, pepper plants need 6–8 hours of direct sunlight per day to grow and photosynthesize properly. 

3. Soil

Other weather patterns like droughts and floods impact the soil that your plants are in. This affects the amount of nutrients in the soil needed for your pepper plant to grow and produce the best that it can. Maintaining the soil of your plant is crucial. If your pepper plants aren’t growing properly, using fertilizer into the soil around the plant can give it the boost that it needs to fully grow. 

How is Days to Harvest Calculated?

The process isn’t terribly complicated, but it does take time to complete. Growers come up with these estimates based on the average time it takes for a certain type of pepper plant to grow and produce ripened peppers.

There’s been a lot of debate on determining how to officially start the countdown of a plant’s days to harvest. Some growers said to start the countdown when the pepper seeds are officially sown into the ground. Others have stated it shouldn’t start until the plant germinates, or when the first leaves have sprouted. For seedlings, the days to harvest countdown shouldn’t start until the transplanting process is complete.

It sounds more complicated than it is. A general rule: start the countdown when the seed or seedling is officially in the ground.

But keep in mind that your days may be different than what the packet states. Consider the factors listed before that can influence your pepper plant’s growth and know that the timeline will likely deviate from the average one.

Pepper Days to Harvest Cheat Sheet (from planting to maturity)

It’s important to understand that one plant has a different pepper harvest time than another plant does. The table below shows some days to harvest dates for commonly grown peppers. You'll notice that days to harvest superhot peppers are higher than others since they generally take longer to grow and mature.
