How deep should I plant a bare-root hybrid tea rose? 
Hybrid tea roses are produced by grafting (budding) the desired variety onto a hardy rootstock.  Exposure to low temperatures and rapid temperature changes in winter can severely damage or destroy hybrid tea roses. The bud union area is the most important part of the rose. When planting hybrid tea roses, the bud union (denoted by a knob or crook in the stem) should be planted 2 to 4 inches below the soil surface to prevent the destruction of the bud union area from harsh winter weather. 

Is it possible to divide a lilac? 
Many perennials are easy to dig and divide. However, digging and dividing shrubs is very difficult and not recommended. 
 
Many lilacs produce shoots (suckers) around the periphery of the original plant. In early spring before the shoots begin to leaf out, it’s possible to dig up some of the suckers and move them to another location.  

When should I sow carrot seeds? 
Sow carrot seeds at a depth of a quarter to half an inch beginning in early April in central Iowa. For a continuous harvest, make additional plantings every 3 to 4 weeks. The last practical planting date for carrots is Aug. 1. 
 
Space rows 18 to 24 inches apart. If necessary, thin the seedlings within a few weeks of germination. After thinning, seedlings should be spaced 2 to 3 inches apart. 

How long can I expect a cherry tree to survive? 
Cherries are short-lived trees in Iowa, especially in poor sites. Sweet cherries seldom survive more than 10 years. Sour or tart cherries may survive for 20 to 25 years. When selecting a planting site, be sure to choose a well-drained location.
