  • How best to transplant a trillium?
    Pal_number_email_small

    Hi. I'm including the answer to a similar question we answered at the Elisabeth Miller Library on this topic.

    According to Michael Leigh's Grow Your Own Native Landscape (Olympia, WA: Native Plant Salvage Project, 1999), dividing Trillium is difficult because you must "dig deeply to ensure minimal damage to roots and rhizomes, take special care not to break the stems, and transplants may die back before reappearing the following spring."

    According to April Pettinger's Native Plants in the Coastal Garden (Whitecap, 2002), "Trilliums do not like to be transplanted, so if you decide to move them to another site, be prepared for them to take several years to flower again."

    My personal experience suggests that taking as much of the soil around those rhizomes as possible will give the plant the best chance of success, and I think early fall is the best time, although I don't find any source that specifies a time of year. Right after bloom may be fine too, as it is the recommended time for division according to the American Horticultural Society's Plant Propagation (DK Publishing, 1999).

  • Can I replant flower bulbs after two days?
    Dsc_0339_small

    You have three great questions and I have info to share!

    1. Bulbs: Yes, dig up those bulbs and re-plant. I just bought my favorite Crocosmia ‘Lucifer’ last week and the package confirms to plant in full sun and at a depth of 4”. I think this is a little deep for such small bulbs and you can get a way at a depth of 2-3”. Here’s the general rule for planting bulbs: Plant flower bulbs at a depth of between 2 – 2 ½ times the size of the bulbs. Also, make sure they are not upside down. Plant pointed end up and roots down.

    3. Planting two year old seeds and bulbs:  You can plant your seeds, but check the expiration date on the package. The seeds may or may not be viable.  If you want to make certain your old seeds are OK, you could perform an easy germination test--From Holly Kennell, King County Co-op Extension: If you keep your seeds cool and dry, they will last longer, but can you be sure that they are still good? If they are, you can save yourself some money. Before you order your new seed, do a germination test on any seeds more than just one year old. Here's what to do:

    1. Put exactly ten seeds on top of a damp, folded paper towel.
    2. Put the towel and seeds into a plastic sandwich bag and seal.
    3. Label the container with the date and seed variety being tested.
    4. Leave at room temperature for a week or so. (Leave parsley, carrot and celery longer; they're slow.)
    5. Count the number of seeds that sprout:
    a. 10 = 100% or perfect germination
    b. 9 = 90% or excellent
    c. 8 = 80% or good d. 6-7 = 60-70% or poor -- sow more thickly
    e. 5 or less = 50% or less -- throw the seed out!

    Now, what about old bulbs? Many gardeners plant bulbs and tubers every spring and dig them up in the fall and store in a cool garage. Prior to planting again in the spring, always carefully inspect the bulbs for signs of disease and re-plant the healthy bulbs and discard the unhealthy bulbs. Now, if you’ve discovered some old bulbs that have never been planted, you could plant, but I wouldn’t expect lovely flowers or foliage. Often, the bulbs are dry, shriveled, and no longer viable and should be discarded.  If you aren't sure, give it a try.

    3. Summer Squash is a warm weather Squash. WSU Cooperative Extension recommends planting Summer Squash seeds indoors in May-June in peat pots. http://king.wsu.edu/gardening/documents/8StartingCropsOutdoors-Indoors_001.pdf
    Ed Hume (Gardening with Ed Hume, 2003) recommends sowing seeds outdoors in mid- to late May.

    Gardeners are often faced with the question of what is the frost date for my area. Typically the last frost date for Seattle is March 23. For more information about frost dates in Puget Sound, see: http://www.king.wsu.edu/gardening/documents/40ClimateMicroclimatesandFrostDates.pdf

    I hope this info is useful.  Please feel free to ask for more info and I'll do my best to help.  Enjoy the sun and Happy Gardening!

  • What should I plant in my hanging baskets?
    Dsc_0339_small

    You have a great list started and everyone else has added great tips and recommendations!  My all-time favorite hanging baskets are in the city of Victoria, BC. For inspiration, a list of plants, and instructions how to achieve these beautiful hanging baskets, go to: http://www.victoria.ca/cityhall/pdfs/compar_prknrsy_hngbskt_brchr.pdf

    I also find great ideas by visiting local nurseries, like Swanson’s in Seattle or Wells-Medina in Bellevue. I always marvel at the exotic combinations of plants in the hanging baskets and containers everytime I visit University Village. And for great shade combinations, check out the hanging baskets on the 2nd floor of the parking garage next to Crate and Barrel in Bellevue Square.

    Finally, you probably already know this, but don’t set out your baskets or containers too early. A day like today gets us in the mood and nurseries and garden centers entice us with their beautiful displays. Remember, those pretty plants have been coddled in warm greenhouses and will not fare well in the cold and rain. As a rule, I never plant my annuals until after Mother’s Day or even late-May to early-June. Of course you can gather your plants and even plant your containers earlier, just be careful when you decide to set them outside and be aware you may need to pull them into a garage or protected area from time to time until the temperatures are more consistent.

    Oh, and about Nasturtiums. Yes, they should bloom all season.  An added benefit: the flowers and leaves are edible.  On the downside, many gardeners complain they attract aphids.

    Happy gardening! -Andrea

  • Is my orchid ok?
    Finn3goof_small

    Phalaenopsis orchids are easy to grow. Yours may be getting too much light, too much water, or is too cool.

    I've raised a few dozen. Look for mealy bugs and remove them manually. They will look like a white mildewy powder.
    Cut off the offending leaf. get a larger container and some orchid bark. Transplant and set the the whole container with plant in cool water up to where the stem starts. Leave for a few minutes. remoe, drain, and put somelace shady. Morning has worked best for me.

    Spray with waer on occassion and let the roots get dry. they tend to flower once a year for several months.

  • What should I plant around bulbs/tubers?
    Poppies_small

    It sounds like you have chosen bulbs/tubers that bloom from mid-July through early fall. If you want year round interest, you can edge the front of your bed with a line of evergreen dwarf boxwoods, Buxus 'Suffruticosa', add a few columbines, Aquilegias,that will happily reseed around the garden for spring bloom, and Delphiniums for late spring/early summer bloom. The Aquilegias and Delphiniums can be cut to the ground after blooming. Candytuft, Iberis sempervirens, would give you an evergreen groundcover that blooms early spring. Geranium 'Rozanne' grows 3' x 3' and it has blue flowers constantly from June until frost.

    The list of possibilites goes on and on, but these are tried and true plants that will extend your seasons of bloom and interest.

  • Is it too late to plant Dahlias?
    Shot_1298932179940_small

    Hello!

    Dahlia bulbs (they're actually called tubers) like warm soil temperatures. The are should be well draining. They are native to Central America and Mexico. Given that bit of info, it is actually too early to plant them. I usually plant my tubers in mid April, even though air temps may be above 60 degrees. My soil is clay and takes a while to warm up in spring. A tuber sitting in wet spring soil will be more likely to rot in the ground or just have a very weak start.
    But sometimes you have to plant earlier, or it's just too tempting not to put them in the ground.
    One trick to warm up the soil faster is putting clear plastic or a tarp over the area a week or two before planting. This will dry the area out, and also warm the soil up a bit. Remove the covering before planting.

    Another trick is mounding the area- an area of soil that is raised above the rest of the garden, what we call a raised bed. This has some great advantages- warmer soil earlier in the season, easier to upkeep and weed, and it looks nice...

    Here's a good rule of thumb that will help guide you with dahlias: Dahlias and tomatoes need similar conditions to do their best.

    Good luck with your tubers!!!!~ Juicy

  • Tulip bulbs: is there a continuum great to bad places to buy bulbs?
    Dsc_0148_small

    you're going to have a hard time finding bulbs that are not already planted in soil this time of year - i hope sprouted and planted is what you're looking for!

    the discontinuity you see in cut flowers doesn't really follow with live flowers - especially tulips. the bulbs themselves are little life-support packages with nearly everything that tulip needs to bloom. cut tulips were most likely separated from the bulb too soon, and they starved before the bud developed or the flower opened.

    that being said, if you want great tulips, you're gonna have to pay for them. regular old tulips are fine, but lily-flowering, double-petaled, parrot and exquisitely colored tulips are jaw-dropping and have a price to match. a few garden shops that won't disappoint you as far as selection goes are swanson's, molbak's, well's medina.

    and, since you're going to have to give these bulbs away planted in the  dirt you bought them in, pots would probably be best - but if you've got a glass-drilling bit you could  plant them in mason jars with ribbon around them as long as you made a drainage hole.  it could kill a few of them, but you could also wash all the soil off the bulb and put them in cheap ikea vases with lots of colored marbles and some water.

  • Is it still possible to plant bulb this late?
    Dsc_0148_small

    yeah, it's definitely possible! late-summer-flowering bulbs/rhizomes/tubers like dahlias, daylilies and gladiolas are planted in very late march/early april anyway. don't plant them too early - they're tender.  they'll pop up next year, but they need a lot of time to acclimatize themselves for next winter.  if you're interested in planting already-sprouted perennial rhizomes/bulbs/tubers, you'll see them in garden shops soon.  crocosmia is awesome even though its the hipster of the plant world right now and it makes gorgeous sprays of orangy-gold that double every year.  arisaema is also one of the coolest plants there's ever been.

    you can still plant some of the mid-to-late-spring-flowering bulbs (daffodils & tulips) that say they've been refrigerated on the label, but they're tough to find.  if you do find the refrigerated bulbs, plant them an inch or two deeper than what's stated on the label; it will keep them cooler and they'll receive enough chill to flower.  you're going to have lots more success if you plant those already-sprouted bulbs that are being sold all over the place. you can plant those RIGHT NOW!
