June Tips for nw gardeners



Add color to the garden and containers with annual flowers such as geraniums, lobelia, bacopa, petunias, calibrachoa, coleus, and begonias.

In spring, most houseplants begin to grow more actively. Start applying a fertilizer formulated specifically for indoor plants. Be sure to follow the directions on the product label for best results.

Did you keep a citrus plant indoors for the winter? Citrus benefits from an outdoor vacation in warmer weather but it is important to slowly acclimate your plant to outdoor conditions! Start by putting the plant out in the shade during the day and bringing it in at night. Then slowly increase the amount of time it is outside while also allowing it to gradually get more and more direct sun until it is full sun. This process can take up to a week or more.

You can aerate, topdress, and overseed your lawn through the month of June. Remember to keep it well watered during these activities! See Step by Step Lawn Renovation for more detailed information, and remember you can always ask #heyswansons for help!

The height of the grass generally equals the depth of the roots, so keeping grass a little longer helps build a strong support system. Mow on a medium setting, cutting off no more than 30% at a time. 

In summer, lawns need approximately 1" of irrigation per week to stay green and healthy! Even if you plan to let your lawn go dormant, water about once a month to keep it from dying back completely.
