June

1st Week of June

Make sure annuals have adequate water to help their establishment.
Tomato cages should be put in place.
Monitor for insect and disease problems.
Try to keep your prize-winning hybrid tea roses from blooming. Cut buds as they appear back to five leaves and wait for the spectacular show in July and August.

Continue to pinch or cut blooms back to the first set of leaves.
Sod installation is OK up to this point.
Reapply preemergent weed control to mulched areas where weeds are excessive. DO NOT apply to annual beds.

Watch for annual damage and use repellants where necessary.
Continue to water any seed planted in May until it is well established.
Finish up your annual weed control as herbicides become less effective as temperatures rise and annual weed growth slows.
Make sure all stakes are in place and all vines are being trained or tied to their arbors.

Keep root fertilizing every two weeks to further encourage establishment.
Fertilizing should be finished for the summer except for irrigated lawns.
Keep mums and asters at six inches tall.
During the last week of June, trim Autumn Joy sedum back to 6-8 inches. This encourages thicker heavier stems that will not fall over with the weight of the flower later in the season.
Any spring blooming shrubs like lilacs, Bridal Wreath astilbe, and forsythias should be done flowering, so it’s time prune.
Water any transplants, as they will begin to feel and show drought and heat stress.
