How to Plant & Grow


Lupins are cottage garden favourites, adding bouts of beautiful blooms to the garden. Their statuesque shapes and flowers provide the most enchanting display. 

These perennials are easy to grow, especially when you know how. Without further ado, here’s our complete guide to help you learn how to plant lupins with ease.

When to Plant

Lupins can be planted in spring and early summer, once they’re available online or in garden centres. Lupin seeds are best sown from spring to autumn.

How to Plant

Lupin Modules 
 Our lupins are supplied as modules/plug plants. These are easy to grow - perfect for a beginner. Whether you’re growing them directly outside into the border or into a container, our modules and plug plants are a breeze from the moment they arrive.  
- Dig a hole in the border that’s big enough to house the entire module. If planting in pots, fill a large pot halfway with potting soil and then make several holes that can hold the modules. Do this until the top of the soil from the module is just below the top of the pot.  
- Fill around the modules with soil and firm down gently.  
- Provide support if you’re planting them towards summer.  
- Water well and you’re done!


Lupin Seeds 
 - Soak seeds overnight to aid germination.  
- Plant inside from March to May in trays and keep them warm to help them germinate.  
- Acclimatise them to outdoor conditions once the threat of frost has passed over 7-10 days. 
- To sow directly outdoors, do so from April to May, after the threat of frost has passed.  
- Ensure their sowing area is well-prepared and is free of weeds or rocks.  
- Sow your seeds thinly in your desired area, and thin them apart once they reach heights of 5-7cm. 

Where to Plant

Lupins should be grown somewhere sheltered, either in full sun or dappled shade. As they can grow quite tall and tend to be top-heavy, a sheltered position away from harsh winds is preferable - perhaps close to a fence or wall.

When to Water

New lupins should be watered regularly throughout their first year, especially throughout summer. However, older established plants may not need regular watering, except when in a persistent drought.  


Cut back faded flowers, as this could encourage a second flush. Once they’ve finished flowering in autumn, cut them right down to the ground. 

Common Issues and How to Solve Them

Lupins can be bothered by aphids, which are tiny bugs – often a green or black colour. If you’re concerned that your plant has been affected by them, remove the leaves affected and throw them away. Do not put infected leaves into compost bins. Lupins grown in containers are more susceptible to aphid attacks, so bare this in mind when deciding where to grow them. 

When will they Flower?

Usually, lupins will flower from late spring to early summer, usually from May to July. They’re perfect for bridging the gap between the two seasons!
