Growing Tips for Stockholm

Give Warm-Season Plants a Head Start

Many frost-sensitive plants like tomatoes, peppers, or pumpkins benefit from starting indoors in Stockholm. Begin sowing them indoors as early as March or April to give them a head start.

Improve Your Soil for a Bountiful Harvest

Loose, humus-rich, and well-draining soil is crucial. Before sowing or planting, work in plenty of compost to improve soil structure and ensure nutrient supply.

Ensure Consistent Moisture

Fast-growing crops like radishes or broccoli need a constant water supply. Make sure the soil is always moist but not waterlogged to prevent woody roots or stunted growth.

Protect Frost-Sensitive Crops

Plant frost-sensitive crops like beans, cucumbers, or courgette directly outdoors only from mid-May. Covering them with fleece can offer extra protection during unexpected cold snaps.

Common Pests & Diseases

•

Keep Snails and Slugs in Check

Snails and slugs are a common nuisance, especially in damp weather. Regularly pick them off, install slug fences, or use iron phosphate-based slug pellets to protect your young plants.

•

Combat Aphids

Aphids can multiply quickly. Rinse them off with a strong jet of water or encourage natural predators like ladybirds. A soapy water solution can help with heavy infestations.

•

Prevent Cabbage Root Flies

Cabbage root flies can damage kohlrabi and broccoli. Protect your plants with horticultural fleece or insect netting, installed immediately after planting, to prevent egg-laying.

•

Spot Potato Beetles Early

Regularly check your potato plants for potato beetles and their larvae. Hand-pick these pests to prevent their spread and secure your harvest.
