Starting seedlings

The following is by Linn County Master Gardener Claire Smith:

 

It’s February.   It’s nearly spring.  Never mind that the ground hog saw his shadow, now is the time for all gardeners to commence gardening preparations. 

Following is one of the most popular questions that Master Gardener volunteers are asked on the Hortline:  when should I start seeds indoors for transplanting to the garden?  The often used phrase “it depends” applies to this question.  It does depend on what plants you intend to grow.  The number of weeks from first sowing the seeds to planting outdoors may vary from flowers to vegetables.  Seed start time for some popular ones are as follows:  Geraniums—10 to 12 weeks; Petunia and Impatiens—8 to 10 weeks; Marigold, pepper and eggplant—6 to 8 weeks; Tomato, cabbage, broccoli and cauliflower—5 to 7 weeks; Cucumbers, watermelon, muskmelon and squash—3 to 4 weeks.

If sowing seeds in flats or trays, fill the container to within one inch of the top with your planting medium.  Firm it down, water thoroughly, let it drain.  Fine seeds are sown on the surface and lightly pressed into the medium.  All other seeds are to be covered with planting medium to a thickness of one to two times of the seeds diameter.  Then water from the bottom (submerge) until the topsoil is wet then allow to drain.  Or you can water from the top with a bulb syringe.  Keep the soil uniformly moist, cover the container with a clear plastic food wrap. 

Always purchase good quality seeds.  Use clean containers.  Provide ample space for the seedlings to grow.  Air circulation should be good.  Follow planting directions on the packages and fertilize accordingly.  Adjustment to the out of doors should be a gradual process:  spending some time on the deck or porch before transplanting to beds would be wise.

My daughter and two grandkids are excited to plant their second garden.  Maybe we’ll try planting seeds and see if they get as excited as I do when sprouts commence popping through the soil.

Keeping a pot in the house

   Linn County Master Gardener, Claire Smith, offered the following on keeping mum pots in the house and other fall advice for Iowans:

               

Feel free to ask questions:  Master Gardeners love to visit.  If a M.G. doesn’t have an answer, he/she will be eager to do the research for an answer as well as satisfy our own ongoing curiosity of all plants living—and sometimes dead.  Following are some common fall inquiries:

·         Most trees can be trimmed between December and February.   Hold off on fruit trees until late February.  Clean instruments between trees to prevent disease transfer.  Cut outside of the “collar”.  Maximum trimming should be 1/3 of the tree.

·         Grape Hyacinth may send up shoots now:  it should be o.k.

·         Saving Dahlias and Callas:  do not store in plastic bags as moisture will create mold.  Layer the bulbs, but don’t allow them to touch by putting vermiculate between them.  Cure the bulbs in a warm area for a few days then store at 45’ in the basement.   Do not allow the bulbs to freeze.

·         Oleander can be trimmed.  Cut ¼ off to main branch.

·         Clematis:  some of rabbit’s favorite food!  Try fencing with chicken wire.   No need to mulch.

·         Burning Bush:  can be trimmed any time, but recommend after leaf loss.  Vibrant color this year possibly due to excess spring moisture.

·         Spirea can be trimmed now.

·         Geraniums can be left potted in a sunny window for the winter.  Or, shake off the root dirt and hang upside down in a paper bag in the basement or unheated attic. Dip roots in water monthly.  In February, cut away dried area leaving nubbins.  Dip in Root Tone after potting to initiate growth.

·         Mums:  generally not winter hardy.  Root system won’t withstand Iowa’s freezing winter.   Can keep in pot in the house if cut back.  Plant in the spring on the south/sunny side of the house.

·         House Plants:  will probably have little new growth as they use spend energy adjusting to being moved inside.  

·         Routinely monitor animal management strategy.  In years of high animal population and limited food (think last winter!), they will eat almost anything.

·         Pest –free debris from fall clean up can be composted.

·         Do not fertilize now.  Improve the soil with the addition of shredded leaves, well-rotted manure, or other organic matter.

·         Drain garden hose and put away. 

·         Direct sunlight and freezing temperatures can diminish efficacy of liquid pesticides and fertilizers.

Overwintering geraniums

The following is by Richard Jauron, horticulture specialist at Iowa State University Extension:

Geraniums are popular flowering plants, blooming from May through frost.  However, you don’t have to let the first hard frost destroy your geraniums.  Geraniums can be overwintered indoors by potting up individual plants, taking cuttings, or storing bare-root plants in a cool, dry place.  Regardless of the method, the plants should be removed from the garden prior to the first frost. 

Potted Plants

Carefully dig up each plant and place in a large pot.  Water each plant thoroughly, then place the geraniums in a bright, sunny window or under artificial lighting.  Geraniums prefer cool indoor temperatures.  Daytime temperatures of 65 to 70 degrees F and slightly cooler night temperatures are ideal.  During their stay indoors, water the plants thoroughly when the soil becomes dry.  The geraniums are likely to become tall and lanky by late winter.  In March, prune back the plants.  Cut the geraniums back by one-third to one-half.  The geraniums will begin to grow again within a few days and should develop into nice specimens by May. 

Cuttings

Using a sharp knife, take 3- to 4-inch stem cuttings from the terminal ends of the shoots.  Pinch off the lower leaves, then dip the base of each cutting in a rooting hormone.  Stick the cuttings into a rooting medium of vermiculite or a mixture of perlite and sphagnum peat moss.  Clay or plastic pots with drainage holes in the bottom are suitable rooting containers.  Insert the cuttings into the medium just far enough to be self-supporting.  After all the cuttings are inserted, water the rooting medium.  Allow the medium to drain for a few minutes, then place a clear plastic bag over the cuttings and container to prevent the cuttings from wilting. 

Finally, place the cuttings in bright light, but not direct sunlight.  The cuttings should root in six to eight weeks.  When the cuttings have good root systems, remove them from the rooting medium and plant each rooted cutting in its own pot.  Place the potted plants in a sunny window or under artificial lighting until spring. 

Bare Root Plants

Dig the geraniums and carefully shake all the soil from their roots.  Then place one or two plants in a large paper sack and store in a cool (45 to 55 degrees F), dry location.  An unheated bedroom or indoor porch might be a suitable location.  An alternate (somewhat messier) method is to hang the plants upside down in cool, dry location.  The foliage and the shoot tips will eventually die.  In March, prune or cut back each plant.  Remove all shriveled, dead material.  Prune back to firm, green, live stem tissue.  After pruning, pot up the plants and water thoroughly.  Place the potted geraniums in a sunny window or under artificial lighting.  Geraniums that are pruned and potted in March should develop into attractive plants that can be planted outdoors in May. 

The overwintered geraniums can be planted outdoors in May (after the danger of frost is past).  Before planting, harden or acclimate the geraniums outdoors for several days.  Initially, place the geraniums in a shady, protected location and then gradually expose the plants to longer periods of sunlight.  Plant the geraniums in the garden after the plants have been properly hardened.
