Our May Garden Guide Is Your Bucket List Of Things To Get Done In The Garden 

May Garden GuideWelcome to the heart of spring! May is the month to be in the garden. Chill in the morning. Nice warm afternoons. The heat of summer is just around the corner so getting seedlings off and growing is real important.  Grab your tools, it is time to get after it!

Prune out overcrowded and dead stems of early-flowering clematis after flowering.

Keep up with weeding. They can get ahead of you quickly if you aren’t careful.

May Garden GuideGive your container plants a balanced liquid feed every two to four weeks to promote healthy growth.

Start to closely inspect your plants for pests and diseases – early prevention is easier than curing an infestation.

Look out for signs of blackspot on roses. If discovered, Blackspot can be treated with a systemic fungicide.

Continue to weed beds and borders to prevent competition for water and nutrients.

Continue earthing-up potatoes.

Harvest asparagus spears when they are no more than 7” tall.

Harvest rhubarb, picking only a third of the total amount of stems.
