Hardiness Zones – Planting Months
This planting calendar schedule will take you through each month of the year, for zone 6.
For those of you in the UK and Europe, this guide can be applied. If you are in a different continent, the conditions will vary, as it can be tropical or a dry heat.
Planting zones are areas of hardiness. A planting guide, that enables us to know when to plant vegetables, fruit, and flowers. Each area within a zone has similar growing conditions, this standardization gives us a good guide to what we can grow and when to grow.

Essential Gardening Equipment
Soil pH Testing
You need to make sure that you accurately test your soil to give your plants the best chance. This Apera kit has ±0.1 pH accuracy, see the star ratings over at Amazon.
Germination
The best way to germinate your seeds so that they have a great start is with a germination kit. Seeds that are grown this way produce greater results. Check the specs of the MXIC over at Amazon.
Spade
A trusted spade is a gardeners best friend, it helps you do the work. A long handled spade is the most effective type and this DeWit with a lifetime guarantee is our favorite – see the quality at Amazon.
Gardening Tool Set
For the finer work in the garden, we need those handy tools to help us cultivate. One that you can carry around in the garden is best and we like this well-designed set with super reviews on Amazon.
Greenhouse
Every advanced gardener has a greenhouse and with so many benefits how can we do without. The acceleration and growth rate when using a greenhouse is worth the cost. The Exaco 116 square foot with safety glass is ideal at Amazon. On a budget see the poly tunnel at Amazon.
Dehydrating
One of the issues people have is that their crops produce all at once. The best way to overcome this is with a dehydrator so you can store your food for years and the flavor is amazing. The best one on the market is the Excalibur with a 10-year guarantee, see it at Amazon.
January Planting Zone 6
Temperature: -10 to -0 F (-18 to -23 Celsius)
Indoors: Parsley, onion, leeks, and celery.
Flowers: Begonias, pansies, snapdragons, and delphiniums. You will need to help them grow with some artificial lighting, as the natural light might not be strong enough yet.
Parsley and celery will need a number of weeks to germinate, so it’s a good idea to start early. Growing onion seedlings is also a good idea, as they have higher chances of producing healthy onions than the bulbs.
February Planting Zone 6
Temperature: -10 to -0 F (-18 to -23 Celsius)
For both January and February, zone 5 is quiet month. These are cold months where little can be done in the garden.
The same indoor preparations are continued from January.
March Planting Zone 6
Temperature: 34 to 54 F (1 to 12 Celsius)
Indoors: Tomatoes, eggplants, and peppers (it’s still time)
Seeding: Lettuce, carrots, parsley, radishes, peas, and potatoes. Flowers: Rose bushes can be planted.
Zone 6 is busier in March. If you have seedlings that you started indoors (broccoli, cabbage, parsley, etc.) now is the time to get them out.
April Planting Zone 6
Temperature: 47 to 67 F (8 to 20 Celsius)
Seeding: Spinach, radishes, asparagus, beets, broccoli, carrots, lettuce, peas, and potatoes. Transplant cabbage, tomato, eggplant, and pepper seedlings outside. If there is any chance of frost, protect them with farmer’s fabric.
May Planting Zone 6
