When to Plant Bell Peppers Outside?

When to plant bell peppers outdoors? The right timing for a bumper harvest!

If you want to grow your own bell peppers in your garden, it's important to choose the right time to plant them outdoors. Bell peppers love warmth and sun, and they're not exactly fans of the cold Belgian weather. Planting too early is risky, but too late and your harvest will be limited. Let's take you step by step through the perfect timing and approach!

What is the ideal time to plant peppers outside?

The best time to plant peppers outdoors is when the risk of night frost has completely passed. This is usually between mid-May and early June. A good time is around the Ice Saints (May 11th to 15th), because after that, the risk of cold nights is very small. The weather also plays a role: preferably choose a cloudy day or a day after a recent rain, so the plants don't have to start out in bright sunlight right away.

In a greenhouse or conservatory, you can start much earlier. You can plant out your young pepper plants there as early as April, as long as you keep the doors closed at night and the minimum temperature stays above 10°C. Additional protection, such as a plastic tunnel, can help maintain a constant temperature.

How do you prepare your pepper plants for the outdoor season?

Before planting your peppers outdoors or in the greenhouse, it's important to harden them off . This means placing your young plants outside for a few hours each day for a week to acclimate them to the wind, sun, and temperature fluctuations. Start with an hour or two a day and gradually increase the exposure. After a week, they'll be ready for true outdoor life.

Preferably use pepper plants you've sown yourself in March, or buy young plants from a garden center. Make sure they're sturdy, have dark green leaves, and a stem that's not too thin. Weak plants are more susceptible to diseases and snails.

What is the best place for your pepper plants?

Find a sunny, sheltered spot in your garden. Bell peppers need at least 6 hours of direct sunlight per day to thrive. The more sun, the sweeter your peppers! Choose a spot where they won't get too much wind, and make sure the soil is well-drained. Bell peppers prefer slightly moist, fertile soil, but definitely not wet feet.

You can also plant peppers in larger pots (at least 10 liters) on your patio or balcony. Use a good potting soil and add a little compost or perlite for extra aeration and drainage.

How do you plant your peppers? (in the ground vs. in a greenhouse)

In the open ground, plant your peppers in a row, with about 40 to 50 cm between each plant. Dig a firm planting hole, add compost or a little organic fertilizer if desired, and plant your peppers in. Gently press the soil down and water immediately. It's important to check regularly that the soil remains slightly moist, but allow the topsoil to dry out between waterings to prevent root rot.

In a greenhouse, the approach is almost identical. Do ensure adequate ventilation, especially on warm days. Excessive humidity in a greenhouse can lead to fungal diseases. A little help with a plant sprayer is helpful if the air gets too dry, for example, in strong sunshine or with wind from an open window.

What about support and care?

Bell pepper plants are heavier than they look! Once the first fruits appear, they can carry quite a bit of weight. Support them with a stake or let them grow against a trellis. Harvest regularly, and you'll notice the plants continue to flower and produce new peppers. For best results, apply a little fertilizer or liquid fruit-bearing food every two weeks.

Bonus: What if you don't have outdoor space?

No garden or greenhouse? No worries! You can also keep pepper plants indoors on a sunny windowsill or against a south-facing window. But be warned: without sufficient sunlight, the fruits will remain small. An ideal houseplant for those looking for something simpler is the ZZ plant , which would rather be forgotten than receive too much attention. Or discover the Ficus Lyrata if you want tropical vibes without the green stress.

In summary: when and how to plant peppers outdoors

• When to plant outdoors? Between mid-May and early June, after the risk of night frost (Ice Saints).
