When first signs show up treat right away because this disease spreads rapidly. Prune and discard leaves that are infected. Before purchasing fungicides read the manufacturer’s label for listed disease and how to treat for best results.

White Mold

White mold shows up as a white cottony growth that covers the soil are around plants also the plant’s crown. This fungus is difficult to control because it remains dormant in the soil for a few years. White mold disease can be avoided by controlling the high moisture level.

Soils that are infected along with plants should be removed and discarded, Purchasing daylilies species that are immune to this disease will help.

Bacterial Leaf Spot

The bacteria which cause this disease enters through the plant wound, moist conditions encourage this disease which spreads rapidly. Signs of bacterial leaf spot shows up as foul odor along with plant tissues which are mushy and soft.

Daylilies that are severely infected should be removed and discarded. If the infection is not that server and part of the plant is damaged then remove that section or portion, allow the area where you made the cut to dry, and install the plant in good healthy soil that has good drainage.

Leaf Streak

Leaf streak is caused by a fungus that appears as a dark green spot which is soggy that appears on the plant’s leaves. As the disease progress, the leaves take on a yellow appearance then turn red-brown, which leaves a streaking pattern down the center of the leaves.

Rhizoctonia Crown Rot

Rhizoctonia crown rot is caused by continual wet conditions along with soil that has poor drainage. A dark fuzzy fungal growth will appear at the soil surface as the plant’s crown rots. Relocating your daylilies to the soil that has good drainage will cause the plant’s health to improve.

Deadheading your daylilies

Look for flower bloom that is spent or old and remove with a pruner, the purpose of deadheading spent flowers is so that the spent flowers would not produce seeds but rather your daylilies will spend its energy in producing more blossom.

    • Hello herny good to see you, daylilies are pretty amazing and can really tranforms your garden and landscape areas. When it comes to synthetic or man-made fertilizers can burn your garden plant because of the salt content, therefore, it is always important to read and follow the manufacturer’s label before use.

      If your plant experiences fertilizer burn because of overuse it is best to flush your plant with fresh water because the gold is to remove this excess fertilizer out of the plant’s root zone. If the brun is to server then there may not be any hope of saving that plant so before using fertilizers always read and follow the direction! Hope this helps.
