Pick faded blooms but allow greenery to die off naturally before picking. Braid leaves to keep them tidy. Divide over grown winter iris and order later flowering varieties for mid - summer planting if you haven't already done so. Continue to feed bulbs after blooms fade. Remember, if you add to much fertilizer to your tulips the colors will run.
Tulips prefer a pure, loamy soil.
The soil around Stargazer Lilies and daffodils should be kept moist and mulched during growing period. Later, throughout the summer a thorough drying will do them good. They will not do as well if you keep the bed watered to suit the needs of other plants. Spray the lilies with this mixture to fend off deer. Many wild daffodils will naturalize or spread.
