Plant Trees Carefully

If your plans include planting a new tree, you can ensure its survival by proper planting. Avoid the mistake of planting the roots too deeply. When a tree is set too deep in the planting hole there is a tendency to overwater and the roots will not be able to receive enough oxygen. Dig the hole only as deep as the container, but make it much wider so the root growth will spread out and the tree will get off to a healthy start.

Repel Rose Cane Borers

As you inspect the rose garden, look for tiny holes being bored into pruned rose canes. These are caused by small carpenter bees that frequent the rose garden. Though this is a beneficial insect needed for pollination of fruits and vegetables, some rose canes can be killed back by their activity. A helpful tip to seal pruning cuts is to squeeze a dab of carpenter's wood glue on the fresh wound. This treatment will exclude the bee from boring into the rose cane.

Capture Invading Slugs

Search through the perennial flower garden and throughout ground covers for an abundance of slugs. The month of rainy weather has made it perfect for slugs to survive and thrive. Hand-picking is a great recreational method of reducing the number of these destructive pests or trap them underneath newspapers. Tidy up the garden and mulch the flower bed with cedar shavings which can help to deter marauding slugs.

Inspect for Hiding Aphids

Be on the watch for infestations of leaf curl aphids attacking snowball bushes, purpleleaf plums, and many other ornamental landscape plants. These aphids will cause the leaves to grow distorted, curl inward, and dry up. This helps to protect the aphids from applications of insecticides. Try hosing down the aphids with a strong stream of water or pick off the worst of the infested foliage.

Set Out Water Plants

Now that the weather has started to warm up, it's time to put out the tropical water lilies and other water plants in your outdoor water garden. You can easily fertilize the plants by poking a special fertilizer tablet into the soil of each water lily pot. This fertilizer will slowly dissolve and release nutrients to the plants as they need it. Fertilize every four to six weeks throughout the summer months.
