APRIL - GARDEN PREPARATIONS

Here we go again with another annoying post about what you should or can be doing now for vegetable gardening...

• It's finally time  to start your warm weather vegetables indoors.   Remember these seeds like starting soil temperatures of  at least 60°F, but between 70°F and 78°F is what  tomatoes, peppers, eggplants etc. really like.  

•  If you have already started onions,  kale, cabbages, broccoli, and Swiss chard, you can set these out.  Place the leeks in a trough so that you can fill in around them as they grow to blanche the stalks. Lettuce can also go out, but it  may need protection against drastic temperature drops - do you have a cold frame or cloche? 

• It's not too late for peas, parsnips, radish, and spinach seeds to go in the ground.

• Now is also the time to plant new dwarf fruit trees in your yard. Get them started now if you didn't buy and plant them  last year - you won't get fruit for a few years or so anyway.    Look for the graft line on the stock and make sure to  plant it at least 2 inches above  soil level or you may discover you have a full size standard specimen in 10 years... The Cornell Guide to Growing Fruit at Home will answer all the other questions you might have about turning your yard into an orchard.

• It's also a good time to add any compost or peat to the garden. Better to work it into the soil now then when the garden is half planted.  I find this is easier to do  using raised beds or raised rows, than digging a trench,  mixing in amendments and refilling the trench.  If your soil is compacted, do not just dig a small hole  and mix in soil  amendments for a single plant.  The plant's roots will probably stay confined to the hole. [Although digging a very wide hole would be okay, but raised beds or rows are an easier approach.]

• REMEMBER to label your rows and beds...  AND,  label those seeds you are starting in the cellar or in the sun room.  

What to start seeds in? 

We've mentioned before that having heat mats and grow lights are very desirable items for starting plants indoors. If you have a small garden plot, however, these items entail a significant investment  that might seem like  an indulgent luxury. A single 4 foot grow light, a heat mat and  a timer  can easily cost between $150 and $200. You can also create your own grow light system by  using a regular fluorescent fixture and rigging an adjustable suspension system for it.  It's almost as good as a gold standard model.

If you can keep your set up out of the cellar, (say, someone gives you  permission to have it  in the living room) you can dispense with the heat mat, but a grow light really is worth its cost. Planting trays and containers or pots are areas where you can economize. I tend to use large 3 1/4" pots that allow me to grow 24 tomatoes under a grow light. By using smaller pots you could double or triple that number, but you may need to transplant  your children  before relocating them to the great outdoors.

Container options include everything from  compressed manure or peat pots, plastic trays of small plug cells in various sizes  up to 200+ seedlings, to thin plastic cells in the popular 6-pack format. Of course, paper cups will also serve the purpose. Because I sometimes exhibit very frugal behaviors,  I  continue to look for and pick up  containers abandoned by other gardeners. This has allowed me to avoid buying starting pots of any kind for years.  I have also saved and used small yogurt cups  for pots. They work well, but you need to make  drainage holes in their bottoms.

Compressed peat or manure pots

Some gardeners, whom I know, like  using compressed manure or peat pots, but I'm sort of neutral about it. Their advantages include  reducing the risk of damaging fragile young roots during transplanting and decomposing over the course of a growing season.  The downsides are that 1) it is important that no part of these pots  be exposed to the air because the compressed peat or manure sides can wick volumes of water away from the your seedlings; 2) if you do not keep your garden well watered and the pots moist, the roots of your seedlings may   have difficulty piercing the dry pot sides resulting in stunted plant growth; and 3) you have to buy them every year.

Some kind of leak proof tray for holding your plant containers is essential because the containers have to be able to drain and/or absorb water.  Disposable aluminum baking sheets can also serve the purpose, but  they are too flexible  for easily moving the plants around.  Some of the commercial plastic plant trays are not  very sturdy either -- look for trays that have reinforced bottoms! If you decide to use commercial plant trays, consider also obtaining the clear domes (i.e. covers) for them.

The domes  help maintain the temperature and restrict moisture loss while your seedlings are small. They are commonly available in two sizes: 2" and 7" heights). I have also  used the clear plastic bottoms of salad boxes from grocery stores for this purpose. Once your seeds have sprouted, it is important to monitor how tight the covers need to be on the trays.  Keeping the environment under a dome too moist can promote the growth of molds and lead to problems. I use  2" domes and just prop up the domes as the seedlings grow.  When the seedlings get to about 4" in height, I remove the domes.  




Now, get going...
