It’s June… What Needs To Be Done
- Buy and plant crape myrtles in bloom to be sure you are getting the color you want. Know the variety’s mature size to avoid future pruning. Look for thgose varieties that are resistant to powdery mildew.
- Plant seeds for fall tomato transplants in containers; however, get the variety that mature early.
- This is the best time to plant vinca (periwinkle) in full sun. Look for the variety ‘Cora’ since it is resistant to soil-borne diseases. Water with drip irrigation or soaker hose to keep water off the foliage.
- Plant these tropical annuals for their flowers: tropical hibiscus, ‘Gold Star’ esperanza, mandevilla and Mexican heather. Use croton, bougainvillea and variegated tapioca for their foliage color.
Fertilizing and Pruning
- Prune back autumn sage and mealy cup sage by one-third their size. Deadhead salvias, as well as annuals and perennials to stimulate more growth to allow the plant to continue re-blooming until late fall.
- Continue to prune as necessary, fall blooming plants such as Mexican bush sage, mountain sage, Mexican mint marigold, copper canyon daisies, asters, and mums to keep them compact and prevent buds friom forming prematurely. Don’t prune after September when buds begin to form.
- Remove flower stalks on coleus, caladiums, lamb’s ear and basil before buds open. This will promote new stem and leaf growth.
- This is the second time to use an all-nitrogen, slow-release fertilizer on turf grasses. Cut the amount by half to prevent excessive growth which means more water and more mowing.
- Fertilize container plants and hanging baskets with a water-soluble fertilizer every one to two weeks.
- Control aphids on crape myrtles with a strong spray of water.
- Spider mites can be especially troublesome at this time, especially on tomatoes. Treat with an appropriate organic or chemical pesticide, if needed
- Control webworms in pecan and other trees using a long-handled pole pruner. Remove while webs are small.
- To deal with the hot weather, water deeply and less often and hand water newly planted shrubs and trees.
- Take a good look at your landscape while at the height of summer development. Make notes on how the landscape can be better arranged; plants that need replacement, overgrown plants that need to be removed; or possibly areas that can be converted to more family-friendly activities. Save this information for implementation later in the year or next spring.
