Monthly Gardening To Dos
May


Mulching - If you haven't done it already, now's the time. Apply 2-4 inches of mulch to perennial beds and trees. A good layer of mulch will help keep soil moist and inhibit weeds. Plus, it gives your landscape a finished look. How much mulch do you need? Find out here! 
PHANTOM TIP! We recommend 2 inches of mulch for existing beds and 4 inches for new beds. 

Fertilizing - Apply a balanced fertilizer to all of your trees, shrubs and perennials if you have not done so yet. Make sure to follow recommendations for specific plants, not everything needs fertilizing. Annuals benefit from regular fertilizing about every 4 weeks for good bloom production. Early blooming shrubs may need feeding after the first flush of blooms.  Rhododendrons and Azaleas will need an acid fertilizer now to keep the foliage from yellowing.


Transplanting - Now that the ground has thawed and it's still a bit cool, it's a good time to transplant. Make sure that anything you move hasn't started any new growth yet. This will help alleviate some transplant shock.
PHANTOM TIP! Many trees, specifically Maples, cannot be transplanted once they have leafed out. If you need to move one wait til the fall when the tree is starting to shut down.

Deadheading - Remove spent blooms from early flowering shrubs and shrub roses. Deadheading will improve the appearance of the shrub and encourage faster re-bloom. Rhododendrons should be pruned as soon as flowering is complete. Deadhead your spring flowering bulbs if you haven't yet. Be sure not to cut back the foliage until it is yellowed and withered. Pinching back annuals will promote fuller growth. Petunias and Zinnias in particular will benefit from pinching back when the have reached about 4-6 inches.
PHANTOM TIP! Make sure to get supports around your top heavy plants before they get too big.
