FertilizingHow-to : Fertilization for Established Plants
Established plants can benefit from fertilization. Take a visual inventory of your landscape. Trees need to be fertilized every few years. Shrubs and other plants in the landscape can be fertilized yearly. A soil test can determine existing nutrient levels in the soil. If one or more nutrients is low, a specific instead of an all-purpose fertilizer may be required. Fertilizers that are high in N, nitrogen, will promote green leafy growth. Excess nitrogen in the soil can cause excessive vegetative growth on plants at the expense of flower bud development. It is best to avoid fertilizing late in the growing season. Applications made at that time can force lush, vegetative growth that will not have a chance to harden off before the onset of cold weather.
LightConditions : Partial Shade
Partial Shade is defined as filtered light found beneath trees with high limbs. Partial shade usually offers some protection from direct afternoon sun.
Conditions : Filtered Light
For many plants that prefer partially shady conditions, filtered light is ideal. Good planting sites are under a mid to large sized tree that lets some light through their branches or beneath taller plants that will provide some protection.
Conditions : Bright Light for Houseplants
Houseplants requiring bright light should be placed within 2 feet of an eastern or western exposure window or within 2 to 5 feet of a southern exposure window.
Conditions : Full Sun
Full Sun is defined as exposure to more than 6 hours of continuous, direct sun per day.
WateringConditions : Moist
Moist is defined as soil that receives regular watering to a depth of 18 inch deep, does not dry out, but does not have a drainage problem either.
Conditions : Normal Watering for Houseplants
Houseplants that require normal watering should be watered so that soil is completely saturated and excess water runs out the bottom of the pot. Never water just a little bit; this allows mineral salts to build up in the soil. The key to normal watering is to allow the top inch or two of potting soil to dry out between waterings. Check frequently as certain times of the year may dictate that you water more frequently. Also, some plants that require normal watering during the growing season, may require less during the winter months when they are dormant.
PlantingHow-to : Repotting Orchids
Potting Terrestrial Orchids Good drainage is important. Mix 3 parts fibrous peat, 3 parts coarse grit, 1 part perlite, and 1 part charcoal. Select a pot that will accommodate roots and about 2 years growth, but no more. Make sure that it has a drainage hole. Hold the orchid over the pot so that the crown is just below the rim of the pot. With your other hand, fill pot with moistened soil mix, tamping to firm. There really is no need to add crockery to the bottom of the pot, but you may want to add a small square of wire mesh or other permiable fabric over hole in bottom of pot. Potting Epiphytic Orchids Epiphytes prefer conditions where roots can be exposed, therefore, tight pots and close-contact soil mixes do not work well and will induce rot. Mix 3 parts dust-free, medium-grade bark, 1 part coarse grit or perlite, 1 part charcoal, and 1 part peat moss together, OR use a commercial orchid mix. As with the terrestrial orchid, select a pot that will accommodate roots and about 2 years growth, but no more. Make sure that it has a drainage hole. Even better, select an orchid pot, which has vertical slits down sides. Hold orchid over pot so that crown is just below the rim of the pot. With other hand, fill pot with moistened bark mix, tamping to firm. Some epiphytes do not need to be potted and prefer to grow on a mound or slab of bark. Until roots attach, tie orchid in place with fishing line. Constant humidity is a must. Support Orchids that have long flower stalks will need staking. Staking is best done as stem grows and before buds open. Many growers prefer to insert stake when potting orchid, but it is up to you.
ProblemsPest : Spider Mites
Spider mites are small, 8 legged, spider-like creatures which thrive in hot, dry conditions (like heated houses). Spider mites feed with piercing mouth parts, which cause plants to appear yellow and stippled. Leaf drop and plant death can occur with heavy infestations. Spider mites can multiply quickly, as a female can lay up to 200 eggs in a life span of 30 days. They also produce a web which can cover infested leaves and flowers.
Prevention and Control: Keep weeds down and remove infested plants. Dry air seems to worsen the problem, so make sure plants are regularly watered, especially those preferring high humidity such as tropicals, citrus, or tomatoes. Always check new plants prior to bringing them home from the garden center or nursery. Take advantage of natural enemies such as ladybug larvae. If a miticide is recommended by your local garden center professional or county Cooperative Extension office, read and follow all label directions. Concentrate your efforts on the undersides of the leaves as that is where spider mites generally live.
Pest : Mealybugs
Small, wingless, dull-white, soft-bodied insects that produce a waxy powdery covering. They have piercing/sucking mouth parts that suck the sap out of plant tissue. Mealybugs often look like small pieces of cotton and they tend to congregate where leaves and stems branch. They attack a wide range of plants. The young tend to move around until they find a suitable feeding spot, then they hang out in colonies and feed. Mealybugs can weaken a plant leading to yellow foliage and leaf drop. They also produce a sweet substance called honeydew (coveted by ants) which can lead to an unattractive black surface fungal growth called sooty mold.
Prevention and Control: Isolate infested plants from those that are not. Consult your local garden center professional or the Cooperative Extension office in your county for a legal insecticide/chemical recommendation. Encourage natural enemies such as lady beetles in the garden to help reduce population levels of mealy bugs.
Pest : Whiteflies
Whiteflies are small, winged insects that look like tiny moths, which attack many types of plants. The flying adult stage prefers the underside of leaves to feed and breed. Whiteflies can multiply quickly as a female can lay up to 500 eggs in a life span of 2 months. If a plant is infested with whiteflies, you will see a cloud of fleeing insects when the plant is disturbed. Whiteflies can weaken a plant, eventually leading to plant death if they are not checked. They can transmit many harmful plant viruses. They also produce a sweet substance called honeydew (coveted by ants) which can lead to an unattractive black surface fungal growth called sooty mold.
Possible controls: keep weeds down; use screening in windows to keep them out; remove infested plants away from non-infested plants; use a reflective mulch (aluminum foil) under plants (this repels whiteflies); trap with yellow sticky cards, apply labeled pesticides; encourage natural enemies such as parasitic wasps in the garden; and sometimes a good steady shower of water will wash them off the plant.
Fungi : Black Spot
A known rose disease, Black Spot appears on young leaves as irregular black circles, often having a yellow halo. Circles or spore colonies may grow to 1/2 inch in diameter. Leaves will turn yellow and drop off, only to produce more leaves that will follow the same pattern. Roses may not make it through the winter if black spot is severe. The fungus will also affect the size and quality of flowers.
Prevention and Control:Plant resistant varieties for your area. Always water from the ground, never overhead. Practice good sanitation - clean up and destroy debris, especially around plants that have had a problem. When pruning roses, even deadheading, dip pruners in a bleach / water solution after each cut. If a plant seems to have chronic black spot, remove it. A 2-3 inch thick layer of mulch at the base of plant reduces splashing. Do not wait until black spot is a huge problem to control! Start early. Spray with a fungicide labeled for black spot on roses.
Pest : Scale Insects
Scales are insects, related to mealy bugs, that can be a problem on a wide variety of plants - indoor and outdoor. Young scales crawl until they find a good feeding site. The adult females then lose their legs and remain on a spot protected by its hard shell layer. They appear as bumps, often on the lower sides of leaves. They have piercing mouth parts that suck the sap out of plant tissue. Scales can weaken a plant leading to yellow foliage and leaf drop. They also produce a sweet substance called honeydew (coveted by ants) which can lead to an unattractive black surface fungal growth called sooty mold.
Prevention and Control: Once established they are hard to control. Isolate infested plants away from those that are not infested. Consult your local garden center professional or Cooperative Extension office in your county for a legal recommendation regarding their control. Encourage natural enemies such as parasitic wasps in the garden.
