What is Rejuvenation Pruning? Rejuvenation pruning is the removal of old, overgrown limbs so that the plant can grow new, vigorous branches in their place. Plants that require rejuvenation can be hard pruned or pruned gradually. Hard pruning involves cutting the shrub off to a height of 6 to 12 inches (15 to 30.5 cm.) above the ground and allowing it to regrow. The disadvantages of this type of pruning are that not all shrubs tolerate drastic cutting, and, until the plant regrows, you are left with an unsightly stub....

Help, My Carrots Do Not develop! There are several reasons for carrots not forming roots. First of all, they may have been planted when it was too hot. Carrots germinate best when the temperature of the soil is between 55 and 75 degrees F. (13-24 C.). Any warmer and the seeds struggle to germinate. Warm temperatures will also dry out the soil, which makes it difficult for seeds to germinate. Cover the seeds with grass clippings or the like or a row cover to help retain moisture....

Red Tipped Photinia and Disease Symptoms The main culprit among photinia bush diseases is Entomosporium mespili, the fungus that causes photinia leaf spot. Like most plant fungi, this one thrives in the cool, moist environment of the fall and spring and attacks the most vulnerable new growth that gives the shrub its name, red-tipped photinia, and the disease spreads from there. The photinia fungus won’t kill the plant immediately or even during the first season but will return year after year until the constant leaf drop and the depletion of nourishment that results weakens the plant to the point of death....

How Do Roots in Plants Develop? In most cases, the beginnings of the roots in plants are found in the embryo within the seed. This is called a radicle and will eventually form the primary root of a young plant. The primary root will then evolve into one of the two main types of roots in plants: a taproot system or a fibrous root system. Taproot– In the taproot system, the primary root continues to grow into one main trunk with smaller root branches emerging from its sides....

White Spots on Sago Palms Cycad aulacaspis is only tempted by plants in the cycad family.

Generally, ornamental grasses are not cut back until the early spring, which allows the grassy fronds to add some aesthetic value during a time when most plants are dormant. Once established and in their second year from planting, ornamental grasses require very little maintenance beyond occasional division and cutting back, or cleaning them up in the early spring....
