Horticulture Tips for June

Home Grown  by Keith Reed
Consider the following tips for your June landscape:
  • Almost all ornamental landscape plants, and quite a few vegetables, benefit from a good layer of mulch to help retain moisture and keep soil temperatures down. Transition from cold to hot this year happened pretty fast; mulching as soon as possible should help them weather the summer better.
  • Based on client feedback, tick populations are higher than average around the area this year. Insecticides labeled for insect and tick control are effective on fleas and ticks when applied correctly, but keep in mind these products tend to be “broad spectrum” and are equally effective at killing beneficial insects as well. Sometimes the best line of defense can be simply protecting ourselves by applying a product containing DEET around on our shoes and ankles.
  • We’ve talked quite a bit about poor looking Bermuda this year. Now that it has gotten hot, it should respond very well to nitrogen fertilizer applications. Just remember that it will need adequate moisture/irrigation to get the full benefit from this fertilizer.
  • Strawberry harvest will soon be over. Help insure success with next year’s crop by renovating the patch according to the guidelines in OSU Fact Sheet #HLA-6214 Growing Strawberries in the Home Garden (PDF/Mobile).
  • Spring blooming shrubs like forsythia, azalea, flowering quince, etc. can all be pruned for size now.
  • Summer blooming shrubs like crapemyrtles are preparing to bloom now if they have not already done so. While it does not hurt the plant if you prune right now, it will reduce the potential for bloom this season.
  • Keep an eye on irrigation needs as we continue below normal with our rainfall totals.
