Paprika kweken: warmte, zachte steun en kleur aan de plant

Choose by flavour, shape and use

Jubilandska: A relatively low-growing pepper with elongated fruits that turn from green to red; a manageable greenhouse cultivar. Cut red strips for a vegetable dish or use firm halved fruits in the oven. Combine green and red only if you want that variation in flavour.

The flavour is described as sweet. Red-ripe fruits are the choice for a sweet pepper dish; green represents a different stage of ripening.

Chinese Giant Sweet: Large, block-shaped peppers with plenty of flesh: an old cultivar for generous portions and a substantial place in the greenhouse. Stuff large halves with rice or vegetables, or cut broad strips for grilling. One large fruit provides several portions.

Mild and sweet is the described profile. The cultivar focuses on plenty of flesh rather than a distinctly hot flavour.

Flynn: Small snack peppers on a fairly compact plant, suitable for a pot on a warm balcony or terrace. Eat the young, ripe harvest fresh or cut small strips for a lunchbox. This keeps the juicy texture recognisable.

The source describes sweet, juicy fruits. This profile suits raw snacking, without implying that every snack pepper is the same cultivar.

Corno di Toro geel: Elongated Italian peppers that ripen yellow: a horn-shaped alternative to a square block pepper. Halve long fruits for grilling or cut yellow strips for a salad. An opened half is also suitable for stuffing.

The described flavour is sweet and fragrant. Ripe yellow fruit gives this cultivar its own kitchen profile and colour.

Colour tells part of the story

A green sweet pepper is often a fruit picked earlier, while further ripening brings its final colour and flavour. Colour also depends on the cultivar: red is not the end point for every sweet pepper. Look at the cultivar choice first, then at when you want to pick.

Start with the warmest spot you can offer

Sweet peppers need warmth throughout growth. Dutch seed producer De Bolster recommends growing under glass or a polythene cover. Outdoors, a warm, sheltered spot may help, but a cool season remains a limitation. Choose that position before sowing, so raising the young plants fits the space available later.

A seedling needs time as well as light

Sweet peppers need a long period of raising under cover. The American university source starts well before the frost-free planting-out date. This is a reason to plan ahead, not a universal Dutch sowing date. Give young plants enough light and warmth. Consider whether you can keep caring for them properly indoors until their final growing position is suitable.

Plant at the same depth and let the roots grow

Let young plants acclimatise gradually before moving them outdoors. Plant sweet peppers at the same depth as in their growing-on pots. Choose soil that retains moisture while also draining excess water. The rootball needs a good start; a warm afternoon alone does not tell you how cold the following night will be.

A potted plant develops load-bearing branches too

A large pot makes growing sweet peppers possible on a terrace or balcony. Provide drainage and add support when the plant needs it. Load-bearing branches may break under the weight of fruit. Tie in with soft material and leave room for growth. Pinching out the top is not routinely necessary and may delay fruiting: choose that intervention deliberately.

Follow the flower first, then the small fruit

Not every flower becomes a fruit. Irregular moisture supply can weaken flowers and young fruits. Water the root zone and look beyond a wet surface. When a flower is lost, investigate the conditions around the plant before deciding that the cultivar does not work in your garden.

Pick green or leave on the plant to colour?

A fully grown sweet pepper can be harvested green or left on the plant longer to change colour. That choice affects its use in the kitchen and the wait for the next harvest. Do not expect harvested green peppers to ripen in the same way as tomatoes; let the desired ripe colour develop on the plant.

The harvest finds its purpose in the kitchen

Sweet peppers can be used raw in a salad, fried or roasted. Choose your harvesting stage with that dish in mind too. Compare fruits of the same cultivar at different stages of ripeness. Keep the cultivar name and tasting note in My garden: this creates an experience specific to your season.

Support a branch before it breaks

Place a stake firmly beside the plant without pushing it through the rootball. Use a wide, soft tie and make a loose connection to the load-bearing branch. Check that the material does not cut into the stem. As fruits become heavier, a second support point may be needed; keep considering the whole plant's shape.

Check fruit patches and dropping flowers

A dry, sunken patch at the bottom of a fruit may relate to blossom-end rot and irregular moisture uptake. A pale, scorched patch on an exposed side may result from strong sun. Check watering, roots and leaf cover before feeding more. Flowers can drop in heat or cold; keep the greenhouse ventilated and conditions around the roots steady.
