Topdress the soil around the Stargazer lily with 2 to 3 inches of organic mulch. Keep the mulch at least 2 inches away from the Stargazer.
Tie each Stargazer to its own stake, placed 2 to 3 inches from the plant. Be careful to avoid damaging the bulb. Use soft plant ties to tie the lily to the stake. Instead of a standard stake, you may find grow rings at your local nursery. These are made especially for lilies. Follow the instructions that come with the product.
Provide the Stargazer lily with an inch of water every week. During hot periods, you may need to water more often.
Apply a 4-8-4 fertilizer to the soil once a month throughout the growing season according to the directions on the package.
Snip off dead flowers just behind the flower head. Allow the remainder of the stem to remain on the plant. It and the foliage help provide nutrition for the bulb.
Wait until the Stargazer's foliage turns brown to trim it back to the soil. Cover it with 2 inches of mulch for the winter.
Keep an eye out for signs of an aphid infestation as these are the most common lily pests. Use a hard blast of water to knock the insects off the plant. If the infestation persists, use and insecticidal soap spray according to instructions.
