Will slugs eat lupins?

Yes, slugs absolutely love lupins and will munch away on them. Large lupins won’t be affected too badly by this but will smaller, younger plants it can be devastating.

Here is a lupin straight from my garden, and as you can see something has been munching on it. The giveaway as to what was eating this plant is right in the middle of the photo. If you look closely you can see a slimy trail all over one of the leaves.

This is the most obvious sign you will see and tells you that slugs and snails have been feasting on your precious lupins.

How to get rid of slugs and snails

So if slugs are your pest, how do you keep them away from your lupins. Well, there are a few options open to you and your choice will depend on whether you garden organically or if you have small children or pets in your garden.

Slug Pellets

if you just want the best way to kill slugs and don’t care about being organic then just put some slug pellets down around your lupins.

If you have pets or small children in the garden though I would advise against this as the little blue pellets can be particularly attractive to small children and they are a poison after all so this could be problematic.

Nematodes

Nematodes are a type of microscopic roundworm, they are found naturally in UK soils. When they enter the host’s body, in our case slugs, snails and release bacteria. This kills the slug and the nematode then digests the slug’s body.

They also change the slug’s behaviour which causes them to die underground, so you don’t have tonnes of dead slugs lying around on the surface of the soil.

Nematodes are a biological way of killing off slugs instead of a chemical way. As I said they are naturally found in your soil, what you are doing with this product is just greatly increasing the number if your soil for a short duration.

If the nematodes are successful and find slugs to eat they will often reproduce and you will have an ongoing slug eating frenzy in your garden.

Beer Traps

A beer trap is an organic way of getting rid of slugs. Essentially you set up a cup or saucer buried into the soil with the top of it level with your soil.

You then fill the bottom of the cup with beer. The idea is that the slugs are attracted to the beer and fall into your trap. They then can’t get out and either drown or are removed by yourself from the cup.

while the idea sounds really good on paper I have often found the ineffective and slugs just seem to ignore them.

More on Lupins

Lupins are a beautiful flower that you will find in many British gardens. Lupins are a staple of British cottage gardens, famed for both their height and colour. Originally hailing from the Mediterranean they are a perennial that will greet you with a gorgeous display year after year.

They produce a large flowering spike that is full of colour and each plant can have lots of these spikes leading to a fabulous display. They will begin to flower around may and can last well into June. The flowers do go to seed quite quickly but your lupin will continue to produce more and more new spikes.

To get the best out of these spikes though it is essential to deadhead the old spikes to give the new ones a chance to flourish. Also cutting your lupins back in autumn can help them the following spring. The seeds are edible but if not treated properly first they can be poisonous to animals and humans. Greenfly can be a common problem for lupins here in the UK.
