Summertime is vacation time for people, not plants! While getting ready for that long awaited trip, it’s easy to forget about your lawn, landscape, vegetable garden and house plants. A little time spent preparing your leafy friends for your absence could save you needless worry and hours of extra work when you get back.

A vacation may be relaxing and rejuvenating for you and your family, but it can be hazardous, even deadly, for your plants. Unless you make adequate preparations before leaving, you could return to vegetable disaster.
One of the first things you might do before leaving home is ask a neighbor to check your plants periodically while you’re gone. All plants need some care. During an extended vacation container grown plants require special attention and different species have different needs. Be sure you give your friend specific instructions for the care of each type.
If you can’t find someone to personally look after your plants while you’re away, there’s plenty you can do prior to departure to make sure you don’t come home to a limp landscape and sickly house plants. Outdoor container plants should be placed in a shady area to conserve moisture. Under a tree or on the north side of a building are good locations. A thick layer of mulch will help conserve moisture for landscape plantings. Mow your lawn just before leaving, cutting the grass a little closer than usual. An unkept lawn can encourage disease, and it’s a tell-tale sign that no one’s home.
Give lawn and landscape plants a heavy watering – especially recently planted beds, which will need extra moisture. Also, thoroughly spray or dust your plants to protect them from insects and diseases while you’re away. If you have flowering annuals, cut the blossoms before departing. If you don’t, they’ll soon stop blooming. Harvest all ripe or nearly ripe fruits and vegetables. Like flowers, they will continue to produce only if they’re picked frequently. Otherwise, they’ll go to seed.
Do a thorough job of weeding. If weeds are allowed to go to seed while you’re away, you can expect to encounter much more difficult problems later in the season – even next year – when the seeds sprout. Weeding eliminates a major source of competition for your landscape plants’ food and water which may be in short supply during your absence.
Plants kept indoors require special consideration. Before leaving home, place your house plants in a room which receives indirect sunlight. Direct exposure to the sun will dry the soil too quickly. Of course, you don’t want to put your plants in a room that’s too dark, either. Too little light will almost always result in leaf drop. And, just before you depart, be sure to water your house plants thoroughly. This is especially vital, because – unlike lawn grass and landscape ornamentals – house plants cannot benefit from any rain that may fall while you’re gone.
You’ll enjoy your vacation more by making sure your plants are well prepared for your absence.

Purple Nut Sedge aggressively moves into any sunny open space and crowds out competitors.
The spring season in panhandle Florida is colorful. Every location from frequently manicured gardens to untended fields and pastures are exploding with hues and tones pleasing to the eye.
These heralds of the warmer weather to come are trailed by the warm season’s greenery which fills in the gaps between blooms. The consistent and ample rains have assured the continuance of a bright and pleasing landscape backed by countless shades and textures of green.
The adequate moisture has also assured the aggressive growth of an individually small, but collectively gigantic, weed which plagues every member of humanity associated with attempting to cultivate plants.
Purple nut sedge, Cyprus rotundus, has emerged en mass from every possible sunny location with soil. This native plant is a rapidly spreading perennial which will take every opportunity to colonize new locations.
The identifier purple is in the name because there is a purple-tinged section of this sedge where it emerges from the ground. The plant is sometimes referred to as purple nut grass because of its long narrow leaves and its erect growth pattern originate from a nutlike basal bulb.
There are other sedges in north Florida, but only yellow nut sedge is identified by a specific color. It is sometimes called chufa and is a popular feed for wild turkeys and turkey hunters.
The dark green, smooth leaves blend in easily with many turf grasses. Beneath the soil’s surface and out of sight, the root system grows in every direction.
Purple nut sedge’s roots are a series of spreading rhizomes and tubers or bulbs identified as nutlets. Each nutlet sprouts a new bunch of grass-like leaves and continues growing the rhizomes.
The densely population of this sedge quickly crowds out most other plants, but most especially turf and forage grasses. It can reach a height of 18 inches on its triangle shaped stem.
The root system’s design assures this plants survival and continued success. If pulled, the rhizomes break off leaving a large number of nutlets to develop and emerge at a later date.
If plowed or tilled, the nutlets are detached and spread to new and inviting locations. Many times nutlets lodge in tillage equipment only to shake loose and deposited in un-colonized locations.
Most herbicides have little on this sedge’s hardy root system. Selected pre-emergent herbicides will prevent many of the nutlets from germinating in spring.
North Florida’s sandier soils provide an ideal growing environment for purple nut sedge. The occasional periods of water saturation from storms do not deter this plant’s rapid and growth expansion to new areas, but it will not tolerate heavy shade.
Purple nut sedge’s extreme competitive nature is a heavy consumer of plant nutrients and robs rivals of important compounds necessary for their survival. Additionally, it produces an allelopathic substance which is toxic to some plants.
Purple nut sedge is found in many locales in North America where the environment is hospitable to its growth. The lush green leaves and touch of purple signify work for anyone who is maintaining a lawn or garden.
