Crop planning

Now is a great time to assess last season’s garden: what worked and what didn’t. Think about what plants you would want more of—as well as less of—this season. As you plan ahead consider the following tips:

  • Succession planting: plant more than one type of short season crop, like radishes, lettuce and spinach
  • Interplanting: intersperse fast growing crops like lettuce, spinach and beets into longer season crops like tomatoes and peppers
  • Extending your season: grow more crops earlier and later in the season. Peas can be planted as soon asthe  ground thaws. (St. Patrick’s Day is a good benchmark.)

Want more tips? Windy City Harvest will host a crop planning workshop at 9 a.m. on Saturday, Jan. 23 at the Arturo Velasquez Institute. 

Start seeding

Before you begin, you will need the following items:

  • great soil
  • container for seeds (seed trays, egg cartons, peat pots)
  • dome 
  • lights (a natural, southern exposure or tabletop)
  • fresh seeds

Note: Know what seeds to start. Do not start root crops inside. Nightshade family plants are great to start inside (tomatoes, eggplants, peppers). 

Start seeds eight weeks before you plant them outdoors. If you plant them too early, you'll end up babysitting them. If you plant them too late, they might be too small and might have issues germinating. The beginning of March is a good time to start seeding. Be sure to provide consistent moisture, heat and light.

How to propagate houseplants

Fill a jar or drinking glass with lukewarm water, pull the leaves from the lower part of the stem, because leaves submerged in the water will rot the cutting. Place the cutting in the water and set the container on a sunny windowsill.

Avoid intense light such as a south-facing window, as too much direct heat and light may prevent rooting. Replace water as needed to maintain the same water level. Be sure the roots are always submerged and that the leaves remain above the rim of the container.

Roots usually appear in one to four weeks. When the roots are a few inches long, plant the cuttings in a pot filled with a lightweight commercial potting soil. You can root several cuttings and plant them in one pot to create the appearance of a full-sized plant.
