The roots of trees continue to grow until the ground freezes. If the weather is dry, continue to water newly planted trees until the soil freezes in winter. Small trees usually require watering for 1 or 2 growing seasons. It may…
Fertilization rates range from 0.50 to 1 pound of actual nitrogen per 1,000 square feet, depending on application time and the quality level of lawn you wish to grow.
To figure out how much fertilizer you will need to apply to your…
The majority of roots, especially those roots that are responsible for water and nutrient uptake, are in the upper 6 to 18 inches of soil. Structural roots that radiate out from the tree and provide support and anchorage can reach a…
To encourage vigorous growth and abundant bloom, hybrid tea, floribunda, and grandiflora roses should be fertilized two or three times a year. Fertilizer applications can be made in early spring (immediately after pruning), during the first…
In Iowa, Kentucky bluegrass lawns can be fertilized in spring (April or May), mid-September, and late October/early November. The number of fertilizer applications is largely determined by an individual’s desires or expectations for their…
Mowing frequency is based on the growth rate of the turfgrass and mowing height. As a general rule, never remove more than one-third of the total leaf surface at any one mowing. Shorter mowing heights require more frequent mowing. A lawn…
Pinch chrysanthemums 2 to 3 times from spring to mid-summer. Remove the stem tips when the shoots are 6 to 8 inches tall. New lateral shoots will develop along the stems. Pinch again when these new shoots reach a length of 6 to…
The key to watering newly planted balled and burlapped and container-grown trees is to keep the plant’s root ball moist for several weeks after planting. Water newly planted trees every day for 4 or 5 days and then gradually reduce the…
Most lawns in Iowa require 1 to 1½ inches of water per week. When watering the lawn, apply this amount in a single application or possibly 2 applications 3 or 4 days apart. Avoid frequent, light applications of water which promote…
Modern roses, such as hybrid teas, floribundas, and grandifloras, require watering during hot, dry weather. The frequency depends upon weather conditions and soil type. In most gardens, a thorough watering every 7 to 10 days during…
Plants in hanging baskets need to be watered frequently (especially in summer). Potting mixes are light, well-drained, and dry out quickly. Plus, hanging baskets may contain several plants. In general, water plants in hanging…
While most shrub or landscape roses are winter-hardy in Iowa, there is still typically some branch die-back over winter. Gardeners should prune out the dead wood just as the new buds are turning green and breaking in spring - typically…
Fruit trees purchased from nurseries and garden centers are usually 1- to 2-year-old plants. The length of time from planting to fruit bearing varies with the species of fruit, the cultivar, and whether the tree is dwarf or standard.…

Plants started indoors or purchased at a greenhouse should be hardened or acclimated to outdoor conditions before transplanting into the garden. Initially place the plants in a shady protected location, then gradually expose them to longer…
Blueberry plants should not be allowed to bear fruit in the first 2 years. Any blossoms which form should be removed (rubbed off). Removal of the flowers will maximize vegetative growth and increase yields in later years. …
Trees are valuable assets to the home landscape. Occasionally the services of a professional arborist are needed to prune a large tree or assess the condition of a tree after a storm. For many individuals, selecting an arborist is a…
The small, white “worms” are probably the larvae of the cherry fruit fly (Rhagoletis spp.). Cherry fruit flies lay eggs on developing cherry fruit in May. Damaged fruit appear shrunken and shriveled when ripe, and usually…
Many peony plants produce few, if any, flowers the first spring. In fact, it’s advisable to pinch off any flower buds that develop the first spring to promote root and foliar growth. Flower bud development requires a great deal of the…
