Like an Ammonia salt base one. If watered and feed properly. When it comes to watering, if the water is puddling before the cycle is over you're watering to long. You also need to know how deep the water is gettin. Once it begins to puddle turn the water off. Time how long it takes to soak in.
Then check to see how deep it has gone. Will determine how deep the water should be. The deeper you can train the roots to grow. The longer you can go between waterings. Wet mops pick up better than dry one. Starving the top two inches of soil of water. Reduces your weed germination. Setting your sprinklers at 8,5,3 minute cycle. Gets better soaking results. Than one 15 minute cycle.
The 8,5,3 is based on how long before it starts to puddle by Multiplying your valves by the watering time. Before you recycle the system. The water will still be soaking into the ground even after it disappears under the surface. If the soil is saturated give it time to soak in.
You want to know how far down the ground is getting moist. Keeping it wet in top layer will pull the moisture to the top. It is why over watered lawns reguire more and more water an fertilizer to keep them green. But you ended up with a dependent welfare lawn. Once you have determined your watering soaking cycle. You'll need to know how often.
Use a clam type post hole digger or a bulb planter to see how long it takes for the soil to dry down about inches. If the soil is still moist 3 days after you water it. Wait a couple of more days. When you replace the sod. Place it level. By using washing sand into the hole it will fill the voids. How long it takes is how often you water. I have had lawns I only watered once ever 3 weeks. A trick to check for coverage, is to place small cups all over the yard.
Than see how closely they are filled to each other. The person that tells you 15 minutes every 4 days. Has been misinformed. But is happy to share their ignorance with you.
That maybe true but I don't know what you don't know. This was my first attempt at anything like this.
There are some varieties that grow two feet each year while others may grow less than an inch per year. To figure out the growth rate of your rhododendrons you need to calculate how tall it will be in 10 years and divide by For example, if you have one that will be five feet in 10 years, you divide five by 10 and you will get approximately a half-inch a year.
In addition, if grown rhododendrons from seeds and not cuttings, then they will bloom slower. Some samples of the growth rate of rhododendron varieties include:. The above growth rate is over ten years according to the online database of The American Rhododendron Society. They also identify a fast-growing rhododendron as one that reaches a height of seven feet after 10 years. These can include the Mount Everest and Brittenhill Bugle. Most will purchase these plants that are in full bloom because if you grow them from seeds, it can take two to ten years for their first blossoms.
These plants are capable of growing indefinitely so there is really no limit on how tall they can grow. They generally range in size from giant forest trees to spreading ground cover that is only a few inches tall. They resemble ground cover instead of bushes. These are called dwarf rhododendrons. They grow about three inches a year and will reach their maximum height in 10 years. They will grow as wide as they do tall resulting in them looking like a cross between a shrub and a tree.
This group will average growth between six to eight inches each year and it will take them 10 years to reach full height.
There are some trees that grow as 80 feet tall. Most of them will be in the eight to ten-foot range. They can grow as much as one foot per year. In 10 years, they will reach 10 feet or more. You can find the largest rhododendron variety in the world growing in India.
It can reach heights of feet. Rhododendrons should be planted in the spring or early fall when the weather is mild. You should also make sure that you plant them where they cannot be damaged by the wind.
To reach any of these heights, the rhododendron will need to have the optimum growing conditions, which include plenty of water, gentle or partial sunlight, and mild temperature.
The base of the plant was regularly mulched, and it is located in a partially protected spot due to the shape of the house. This rhododendron is double the size of our other rhododendrons, which were all planted within the same year. It was about three feet high when it was planted ten years ago. It is now at least seven feet high, and seven feet wide. That is something to consider when choosing a shrub as a foundation planting. I discovered some wild rhododendron shrubs growing just at the back of our property next to the tree line.
Every spring I have been watching these shrubs produce flowers similar to other rhododendrons, and wondered what they were. Sure enough, I discovered that we do have wild rhododendron species here in our province, and those were exactly what we had growing in our yard.
These shrubs were much smaller and thinner than the rhododendrons in the garden. With a wiry appearance, these wild shrubs have the potential to grow to a maximum height of one metre or three feet tall. Currently there are many of these little shrubs growing right at the edge of the woods in dappled shade. They seem to have basically been the same size for a number of years, so I guessed that they must be slow growing rhododendrons.
I checked on the plant specifications for Rhododendron canadense on the America Rhododendron Society website. It turns out that this is a deciduous shrub from the subgenera Pentanthera , so these shrubs are similar to the deciduous azaleas growing in our garden.
I also checked on the plant growth expected in ten years. These shrubs are expected to grow two feet in ten years, or 2. That sounds about right. When considering the question -how fast do rhododendrons grow- for the Rhododendron canadense, the answer is -not very fast at all. If you want your rhododendrons to grow faster, plant them in an ideal location under great growing conditions.
Remember however that they will only grow to the maximum yearly amount expected for that particular species or cultivar.
Knowing in advance the maximum yearly growth expected for any given rhododendron is wise in planning the placement of your rhododendrons. That way you will hopefully not find yourself digging them up and transplanting them into a new location in ten years time.
By giving them great growing conditions you will be giving them a great head start to reach their maximum growth patterns in a timely manner.
