DeepStream Designs knows from projects with Landscape Architects across the country how important using the appropriate planting mix is when growing perennials, trees, and bushes.
Replanting these heavy items with complex root systems will be problematic. Getting it right the first time is well worth the effort.
Often clients use their “Landscaping Contractor” for this work. This may be a good solution if the contractor has extensive experience with container gardening and knows the value of selecting the correct planting mix. Otherwise it could be a mistake.
Why? Many Landscapers are not familiar with using a planting mix as they are usually planting in the earth. By using “dirt” or “soil” it may make the planter too heavy for the load on a roof or balcony.
Dirt, or an improper planter mix, will prevent drainage if it contain clay fines that can block drains, may hold too little or too much moisture. Additionally, dirt might not contain the correct PH and initial nutrients for the plants that you’re going to use.
There is no universally correct planting mix, as area microclimates must be taken into consideration. Selecting a planter mix requires an intimate local knowledge of the complex relationship between all the competing factors for beneficial plant growth and maintenance. Therefore, it is essential to ensure that you have a reliable source for your planting mix.
We have posted a blog on the long-term cost benefits of using a Landscape Architect for even small commercial projects but you still need to ensure they have container gardening experience. Another reliable source may be the nursery where you are sourcing the plants.
Whatever you do, don’t assume that your Landscaper or other source has the knowledge necessary to provide the planting mix. Before starting, ask about their experience with container gardening and what mix they propose to use. Vague or generic answers should be your clue that you need to investigate further before proceeding.
By all means, make certain that whoever does the planting follows DeepStream’s instructions regarding planter drainage using drain pads and filter material. Many “old timers” fall back on gravel and holes in the bottom which will soon clog.
Remember that most of DeepStream’s stock planter liners come with just one threaded drain hole. This is only the minimum, since some installations are inside and require the hole to be plugged or drain pipes attached. One hole means one point of failure with no backup.
DeepStream will drill additional drain holes required by your installation at no charge. Tell us where you want additional drains installed, and we will do it before shipping. You may also add them in the field with a hole saw. Deepstream can supply screw together flange fitting to add straight or 90 degree hose barbs to new holes you add.
