How soon can I put in my garden

Cabbage, broccoli, cauliflower, and onion plants can be planted in early – mid-May as they can handle -3 Celsius temperatures. Should the temperature go lower than -3 makes sure to cover the plants with blankets to save them from freezing.

Most seeds can be planted between May 15th and 20th.

Tomatoes, watermelons, and pepper plants are more weather tender and need to be planted after the risk of frost is gone; end of May or even early June is the safest time.
