QI have bought dwarf lupins and at the moment they are under a small polytunnel. Do I keep them there and do I need to feed them? GW Dutton A Lupins are very hardy so you don't need to keep them in a polytunnel. They don't like sitting in wet soil, however, so bear this in mind when planting them - add some grit if necessary.
Lupins are nitrogen fixers, which means they can convert nitrogen from the atmosphere into nitrates in the soil, via bacteria on their roots. This ability allows them to thrive on poor soil, so don't worry too much about feeding them.
