May Garden Guide: What To Do. Planning, Planting & More…

May Gardening
May is an exciting time in the garden. It’s time to plant both indoors and outside. Time to order seeds if you haven’t already or checkout your local nursery. Discover what to harvest, what to plant and what to do in the garden in May.
May Garden Tasks
May gardening tasks will vary based on where you live and your garden zone. Varying temperatures and weather are likely to cause big changes in the garden this time of year.
Given springs variable weather frost cloth can be used to germinate seeds and protect seedlings.
It’s time to plant the spring garden. The month of May in our home is huge for planning, seed shopping, plot maintenance and seedling starts.
We start our outdoor vegetable and flower beds towards the end of April and cover it with frost cloth to help germinate the seeds and shorten the food gap. By the beginning of May we have salad greens, kale, spinach, radishes, cabbage, leeks, peas and many other flowers and herbs popping up around the soil. Being able to have a fresh homegrown salad the beginning of May is amazing.
This year we are adding more planters and growing up. Meaning we are growing more vertically with trellises to maximize our growing space. So our seed selection will include more peas, pole beans, squash and vining vegetables. I have also added a trellis rose to the cottage garden.
All the garden tasks for this month and throughout the year are based on our Pacific North West zone 7 urban homestead. Again they may vary slightly depending on mother nature.

What To Do In The Garden In May
The weather is still a bit unpredictable in early spring. It’s a great time to mulch and add compost to the garden. Adding a layer of compost is a great way to feed the soil and nourish your new seedling.
This year we added a layer of composted mulch to all our vegetable and regular gardening beds. The difference in plant growth is amazing.

There will always be garden maintenance or garden chores to do no matter the month. May is no exception. Give or take the weather some tasks may require more time others not so much.
