Sorry an alle Steuerberater*innen für die Frage.

I just signed an interview with him on a TV show in the Netherlands, so I guess they just wrapped up filming there. Does anybody know where else they’re gonna film this year?

I recently installed a wooden planter box (100 × 40 × 40 cm) on my terrace. It sits directly on the wooden floor, and I’m now trying to figure out how to handle drainage in a safe and sensible way—without damaging the terrace or causing issues for the neighbour one floor below (their terrace is directly under mine).

I’ve done quite a bit of reading, but I’m now unsure what the best solution actually is. So I’d really appreciate your advice and real-world experience!

Where I’m unsure:

1. Feet under the planter box
I plan to add small feet under the box so it doesn’t sit directly on the wood.
What height would you recommend? Is ~10 mm enough?
What material works best (plastic, rubber, metal)?

2. Drainage tray underneath
I will place a collection/drip tray under the planter box. What size should it be if the planter is 100 × 40 × 40 cm? Should it match the footprint exactly or be slightly larger?
Is plastic the best material for this?
Do I need to install rubber grommets (bulkhead-style inserts) at the bottom of the planter box?

3. Leveling / slope
I think the drainage tray should be slightly tilted, so I was considering using rubber pads or plastic wedges underneath to create a gentle slope.
Again, what material holds up best outdoors long-term (rubber, plastic, etc.)?
Would ~1 mm height difference be enough to create proper drainage?

4. Drainage outlet from the planter box itself
This is where I’m most unsure: some people recommend installing a drainage outlet (e.g. a bulkhead fitting) and a hose (around 10–16 mm diameter) to direct excess water away.

Is this actually necessary in my case, or is it overkill?

My concern is that I don’t really have a safe place to drain the water. If I let it run over the terrace edge, it could drip onto my neighbour’s terrace below. But if I don’t drain it, I risk waterlogging or damage to the wooden planter.

So my question is: do I need a built-in drainage outlet, or is it better to rely on a sealed base and controlled watering instead?

Ideally, I’m looking for a low-maintenance solution that doesn’t require constantly emptying trays.

If anyone has built something similar or has a proven setup, I’d really appreciate your input.

Thanks a lot in advance!

I’m currently planning the planting for several large planters (about 100 × 40 × 40 cm) on my terrace and would really appreciate some input.

Conditions are

• sunny location (can get quite hot in summer)
• irrigation system planned, so plants should have similar water needs
• winter-hardy (should be able to stay outside year-round)
• aiming for a mix of:
  • privacy/screening plants (e.g. climbers or shrubs)
  • some Mediterranean-style plants (lavender, rosemary, etc.)
  • a bit of structure with larger plants or small trees
• overall: low-maintenance and robust

So far I’m considering things like grapevine, photinia, hydrangeas, and herbs.

I now have space for 1–2 additional large planters:
What would you add that fits well with this setup (both visually and in terms of care requirements)?

Thanks a lot for any ideas!

Ich bin gerade dabei, meine Terrasse neu zu gestalten und suche nach hochwertigen Pflanzkästen aus Holz in der Größe von mindestens 100 × 40 × 40 cm.

Am besten erscheinen mir bislang die von Gartenfrosch, aber die erscheinen mir zu teuer.

Mir ist wichtig, dass die Kästen:

• stabil und langlebig sind
• für den Außenbereich gut geeignet sind
• eine funktionierende Drainage nach unten haben (oder sich dahingehend leicht modifizieren lassen)
• idealerweise so gebaut sind, dass man den Wasserabfluss auch kontrollieren oder ableiten kann (z. B. mit Schalen darunter oder leichtem Gefälle)
• innen entweder gut ausgekleidet sind oder sich vernünftig auskleiden lassen (Folie, Geotextil etc.)
• gut aussehen (ein schönes Holz, z.B. Teak oder Lärche)

Hat jemand konkrete Empfehlungen? Gerne auch Tipps, worauf man bei solchen Kästen unbedingt achten sollte.

Vielen Dank!

Ich plane gerade die Bepflanzung für mehrere große Pflanzkästen (ca. 100 × 40 × 40 cm) auf meiner Terrasse und hätte gern ein bisschen Input.

Rahmenbedingungen:

• sonniger Standort (teilweise ziemlich heiß im Sommer)
• Bewässerungssystem ist geplant, Pflanzen sollten also halbwegs ähnliche Wasseransprüche haben
• winterfest (soll ganzjährig draußen bleiben können)
• Mischung aus:
  • Sichtschutz (z. B. Kletterpflanzen oder Sträucher)
  • mediterranen Pflanzen (Lavendel, Rosmarin etc.)
  • ein bisschen „Struktur“ durch größere Pflanzen/kleine Bäume
• pflegeleicht und robust wäre gut

Bisher angedacht sind u. a. Wein, Glanzmispel, Hortensien und Kräuter.

Jetzt hätte ich noch Platz für 1–2 weitere große Kästen:

Was würdet ihr da sinnvoll ergänzen, damit das insgesamt stimmig bleibt (optisch + von den Ansprüchen her)?

Bin für alle Ideen dankbar!
