June Garden Guide


By Mary Jane Frogge, Extension Associate in Lancaster County

Celebrate Pollinator Week, June 21-27, by planting native perennial plants and placing a bee house in your landscape.

Start a gardening notebook. Keep all your gardening records in this one location.

When you buy nursery stock that is container grown, check the root ball and make sure it is not bound too tightly. A mass of circling roots will stay that way even after it is planted in the ground.

Remove old flower heads from annual bedding plants to keep them blooming.

Spring flowering shrubs such as spirea, viburnum, lilac and forsythia should be pruned as soon as they are done blooming.

Remove foliage from spring bulbs after it turns yellow and begins to dry.

Use bark mulch around young trees to protect them from lawn mower damage.

Mid- to late-June is an excellent time to take softwood cuttings of shrubs to start new plants. Some shrubs which can be propagated in this way are spirea, lilac and viburnum.

Leftover vegetable and flower seeds may be stored in a cool dry location to be saved for planting next year.

Keep a close eye on the quality of your spring crops. Hot weather causes lettuce to bolt and become bitter. Plant a warm season crop as soon as the spring vegetables are harvested.

In most cases, blossom-end rot on tomatoes, peppers, squash and watermelons can be prevented. Do this by maintaining uniform soil moisture by mulching.

Identify garden pests before you attempt to control them. If you decide to use chemical control, read the label carefully.

Bats can be an effective way to control insects. One big brown bat can eat 3,000 to 7,000 insects each night. Attract bats by building and placing bat houses in your yard.
