After blooms fade, let daffodils keep their leaves

Bulbs need that foliage to rebloom next year

This has been a long and spectacular bloom season for daffodils, narcissus, anemones and other spring bulbs in Sacramento-area gardens.

But our June-like weather this week quickly brought that early spring show to an abrupt end. Temperatures in the mid-80s dried up remaining blooms and browned the last late-blooming narcissus.

Now, what to do with those straggly remains?

With spring bulbs, pruning off spent flowers usually is a matter of aesthetics. But leave the leaves; that foliage still has work to do.

Faded daffodil bloom
It's tempting to cut all the foliage back after a daffodil fades,
but let those leaves go brown and then pull them.



“Bulbs use their foliage to produce the energy they need to form new flowers,” according to the bulb experts at Longfield Gardens, a major U.S. bulb producer. “So, if you want your bulbs to rebloom, it’s important to leave the foliage in place until it has withered and turned yellow. When the foliage can be pulled away from the bulb with a gentle tug, it’s ready to go.”

Some bulbs will shed their foliage within days; others will hang onto their leaves until July.

“The foliage of early-blooming bulbs such as chionodoxa and scilla fades away very quickly,” notes Longfield Gardens’ bulb experts. “Larger bulbs take longer; a few weeks or a few months, depending on the weather and the type of bulb.”

Trim off spent tulips right after they fade; quick deadheading will coax the bulb to rebloom next spring. Daffodils don’t need deadheading, except to tidy up a flower border or bed. Small bulbs such as crocus and snowdrops spread by seed, so leave those flowers to encourage multiplying. Alliums also tend to self-sow; if you don’t want lots of alliums, remove those flower heads.

Some gardeners tie up their daffodil foliage, but that can cut down on the leaves’ ability to photosynthesize and create energy for its bulb. It’s better to leave the leaves loose.

Longfield Gardens suggests hiding the ripening foliage with companion plants.

“In perennial gardens, you can let the foliage of other plants hide the leaves,” say its garden advisers. “Hostas, daylilies, nepeta and perennial geraniums are a few of the perennials that are good at covering the spent foliage of tulips, daffodils and alliums.”

Cornell University studied this method and came up with 15 best perennial and bulb combinations. See it here:

“Another option is to plant your bulbs in a dedicated area where you won’t mind seeing the foliage,” Longfield Gardens says. “For tulips and hyacinths, this could be in a cutting garden or even part of your vegetable garden. Alliums and daffodils are ideal for wilder areas where their ripening foliage will be out of sight.”

If you have the time, energy and room, move the bulbs so their foliage can age gracefully out of sight, Longfield Gardens suggests. “It's also possible to dig up your spring bulbs immediately after they finish flowering and replant them – with their foliage still attached – in a holding bed. When fall comes, dig up the bulbs and move them back.”

Garden checklist for week of Aug. 9

During this break in the heat, fertilize your garden. Make sure to water before and after applying fertilizer.

*Feed citrus trees their last round of fertilizer for the year. This will give a boost to the fruit that’s now forming.

* Harvest tomatoes, beans, squash, pepper and eggplants to prompt plants to keep producing. Give your plants a deep watering twice a week, more if planted in containers. Also, give them a boost with phosphate-rich fertilizer to help fruiting.

* Watch out for caterpillars and hornworms in the vegetable garden. They can strip a plant bare in one day. Pick them off plants by hand in early morning or late afternoon.

* Mulch can be your garden’s best friend – it conserves moisture while blocking out weeds. But don't let mulch mound around stalks, stems or trunks. That can promote rot.

* Camellia leaves looking a little yellow? Feed them some chelated iron. That goes for azaleas and gardenias, too.

* Pinch off dead flowers from perennials and annuals to lengthen their summer bloom.

* Pick up after your fruit trees. Clean up debris and dropped fruit; this cuts down on insects and prevents the spread of brown rot. Then feed fruit trees with slow-release fertilizer for better production for next year.

* To prolong bloom into fall, feed begonias, fuchsias, annuals and container plants. Always water before fertilizing.

* Fertilize fall-blooming perennials, too. Chrysanthemums can be fed until the buds start to open.

* Prepare for a fall full of flowers by paying a little extra attention to your garden. Cut off spent blooms from roses, annuals and perennials, then give them a boost of fertilizer. Make sure to water plants before feeding. Roses will rebloom about six to eight weeks after deadheading.

* Indoors, start seedlings for fall vegetable planting, including bunching onion, cabbage, broccoli, cauliflower, kale, radicchio and lettuce.

* Sow seeds of perennials in pots for fall planting including yarrow, coneflower and salvia.

* In the garden, direct seed beets, carrots, leaf lettuce and turnips.

* Plant potatoes.
