Come see us from Wednesday through Sunday, 9:05-5:08PM.
For all our local customers
willing to make the trip & save money!)
we have our
Pickup at Nursery Price List available.
Rain, rain,-- When will it Rain? Getting water to our fruits, shrubs, flowers, trees and vegetables is often the difference between healthy
thriving plants and dead ones. Mother Nature doesn't always give us what we need in the way of soil moisture. Shallow rooted plants
and sandy soils make proper watering even more crucial. We've all spent too much time lugging hoses and setting sprinklers, time that
could be better spent gardening. Fortunately, farmers and engineers have devised some clever ways to water. Recent innovations
deliver water efficiently and thoroughly. Modular systems have now been designed that can be scaled up for a 500 acre orchard or down
for a suburban flower-bed. It can be as easy as turning on a spigot.
Many folks are familiar with drip irrigation. In drip irrigation, small emitters drip water onto the root zone of individual plants.
We've used a lot of drip irrigation, but emitters are prone to clogging and water is unevenly applied to the root zone. In sandy soils,
little of the root zone may receive water - it just runs right through. We kept looking until we found a better alternative.
Here at Just Fruits we use microsprinkler irrigation. This is a simple system of flexible polypipe water lines laid where you need water for your
landscape. Polypipe can easily be cut to length with pruning shears or a knife and linked together with simple pressure fittings. No threading or gluing
required! Attached to the lines are microsprinklers that put water where you want it, and nowhere else. Fittings are designed with both hose
thread and pipe thread so the system can easily be hooked onto your outside spigots, or a more complex system can be designed using
traditional PVC pipe and fittings. The systems fittings include tees, straight connectors, elbow, in-line valves for manually turning off parts
of the system and end caps. You can use a manual or battery-operated faucet timer, or a time clock and solenoid valves,
to automate the process. These devices not only save the labor of remembering to turn the system off and on, but they can also
promote healthier plants, due to even and consistent watering. Because polypipe is flexible, UV resistant, and resistant to freezes,
lines can be run on the surface of the bed, covered with mulch or buried. It all adds up to a versatile system that makes watering
your landscape a snap.
The heart of the system is the Microsprinkler. These are small sprinklers that are adjusted to put the
water where you need it. There are several kinds of microsprinklers for different applications.
We also stock several other types of microsprinklers for specialized applications.
There are special applicators for watering vineyards, and clips for attaching the polypipe to decks and walls,
for watering patio plants or window boxes. About the only thing we don't water is lawns. For that,
larger sprinklers do a better job, although the microsprinkler system can be used to make large sprinkler
systems more efficient.
Irrigation with microsprinklers is usually organized into zones. A zone is the equivalent of a hose with a
sprinkler on the end. However, instead of one large sprinkler, microsprinklers are placed as needed
along the hose. Since we like to use a maximum of 30 to 40 microsprinklers per ¾” line, the number of
zones is set by the number of plants you need to water. For most homes, 1-3 zones are more than adequate.
Each zone will be turned on and off separately.
- Maxijet sprinklers water up to an 8-foot diameter, and come with interchangeable pattern caps that enable
you to water all or part of a circle around the sprinkler. This is particularly effective for watering
odd-shaped beds or areas bordering buildings and sidewalks, as the water can be directed away from
the structure. The distance that the sprinkler covers is adjustable and the maxi-jets may be placed on
stakes to cover taller flowers.
- Whizz-head sprinklers cover a round area, up to 12 feet in diameter. They are excellent for
watering large beds or vegetable gardens. The diameter is adjustable and like maxi-jets, the
whizz-heads may be placed on tall stakes if needed.
- Vortex microsprinklers cover up to a 5-foot circle. These are attached to low stakes and are
placed close to the trunk of the tree spraying at ground level. They are perfect for medium to large
shrubs and fruit trees. The amount of water is easily adjustable and the large aperture makes them
easy to clean. They are also very inconspicuous.
PLANNING YOUR SYSTEM
In this section we'll discuss the basics of planning your system. We'll concentrate on the home system, but we routinely design
and install large orchard systems. Call us for help no matter what size system you need!
- The first step in planning your system is making a sketch of your property.
Where are the water pump, the existing water lines, and the spigots? Which flowerbeds
or shrubbery need water? A sketch map with approximate distances and locations is all
you need. Draw in areas to be watered and label by types and sizes of plants.
Remember that different types of plants need different amounts of water.
- After making your map, decide how many zones you will need. Flowerbeds are
usually best watered with maxijets and whizzheads while shrubs, fruit trees and
landscape trees usually do better with vortex microsprinklers. We recommend
that zones contain no more than 25 maxijet microsprinklers on a ¾” line or 10
microsprinklers for a ½” polypipe line. Vortex microsprinklers should be rated at no more
than 45 per ¾" line or 20 per ½" line. You can mix maxijet microsprinklers and vortexs on the same line. For each zone
identify a water source. This can be either a water faucet for simple systems or a PVC water line for more complicated systems.
- Bring your plan and a list of the parts you need in to us. We'll go over it with
you and suggest ways to make things as easy as possible.
- Or just make us a rough sketch of your yard and we'll design your system for you.
FOR SIMPLE SYSTEMS USING A HOSE BIBB: The system first begins with
a back-flow preventer. This ensures that no stale, algae-laden water trappd in the
line gets back into the well or city water system. Next is a Y valve. This allows you
to operate the system and a water hose at the same time. From here you can either go
with a manual or battery-operated timer. Next comes the pressure reducer.
This slows the water pressure to 20 psi, which extends the life of the microsprinklers
and keeps the mist from being too fine, causing the wind to blow it off the plants.
Past this is the poly tube adapter into which you push the poly line that goes to the plants.
FOR COMPLEX SYSTEMS:The system begins with an irrigation filter.
This is designed to trap small particles that might clog or wear out the components
of the system. This and a more elaborate back-flow preventer are usually inserted
at the well-head or main city waterline to treat the entire water system. Next
comes the manual valves or electric solenoids that turn the water off and on to the
zones. These can be placed all together at the head of the system and then the water
is distributed to the various zones via either PVC or polypipe. Or main line pipes of
PVC or polytube can be run out to the zone and then the valve attached to the line
(if you're using electric valves the wires used to power the valve are run in the trench
with the pipe). Whichever way you choose you will need to add the regulator at this point
and then the poly adapter (or PVC to polytube adapter). From there you go
polytube to the plants.
