Using Weed and Feed with Squills

I have beautiful Siberian squills in the wooded area behind my home that first appeared two years ago. I usually fertilize the area with weed and feed to keep the dandelions, thistles out and have nice shade ground covers, hostas and shade flowers thriving. Will weed and feed kill the Squill or prevent the new seeds from growing? I want to create a lush bed of these blue flowers without other weeds taking over.

The term weed and feed is usually used for lawn products designed to fertilize the grass and kill any existing broadleaf plant. This would include hosta, groundcovers and other non-grass plants. Are you using a pre-emergent like Preen combined with a fertilizer? These products are used in gardens and designed to prevent seeds from germinating. This includes desirable seeds of garden and native plants. Squills spread by both seeds and bulblets. Preen does list use of their product for several bulbs but does not include squills on their website. Check the label of the product you are using for a list of tolerant plants and any precautions that need to be taken. Most companies have a website or 800 phone number you can call for further information on their particular product.
