Cool’s advice for March

“To plant is to live” Cool

Temperatures are rising, the soil is warming! Time to sow and plant and prepare a wonderful harvest!

This transition period is unstable: check your area frost dates; check that the weather conditions are suitable for planting or sowing. If you plant from seeds and are located in cool areas (Northern Europe), wait until the soil has warmed up otherwise sow indoors and transplant seedlings later. In warmer areas (Mediterranean, California…) you can sow directly outdoor.

What to harvest now

🌾 Now can still be harvested the last winter vegetables and perennials: winter salad, turnips, cauliflower, cabbage, parsnips, leeks, and perennial aromatic herbs


What to sow or plant now

🌱 You can sow now early spring plants that tolerate lower temperatures: lettuce, spinach, peas, radishes, carrots, cabbage

🌱 You can sow now directly outdoor in warmer areas and indoor in other places : tomatoes peppers, zucchini, eggplant, cucumber

To-do list

✔️ Don’t prune grape vines after late winter to avoid weakening your plants

✔️ Put supports in place for beans, peas or plant them in proximity to companion plants (Corn)

✔️ If you amend your soil or balcony or window sills containers with supplements now, this should be done at least three weeks before you plant

✔️ Repot container-grown fruits if needed

✔️ Protect your early seed sown from birds and slugs with natural controls


Sustainability actions

🐝 Enrich the soil by using manure fertilizers (cover crops or green fertilizers):

  • Lupin: enriches the soil through nitrogen fixation
  • Sunflower: helps to stabilize the soil thanks to its robust root system. This is particularly beneficial if your area is prone to soil degradation
  • Rye: enriches the soil though adding organic matter that increases the soil’s ability to retain moisture. Additionally, rye can inhibit the germination and growth of certain weed species
  • Other: phacelia, alfafa…
