Waterlogging issue

Thank you for your advice, Gardenboy.

I'd actually recommend catch basins over a French drain system. The catch basin approach would be less disruptive to your established garden, especially with that central tree. Tree roots, even from a small tree, can spread widely underground, and installing a French drain might risk damaging these roots. With plants concentrated in the corners, you could strategically place 2-3 catch basins in the lowest points of your garden, typically in the open spaces between your plantings. These basins can then be connected by smaller pipes running along the least planted routes to direct water away from your garden. Think of catch basins like strategic little wells - they collect water at specific points and channel it away. The installation is more localized and less invasive than digging a long French drain trench across your garden. You'd only need to dig specific spots for the basins and narrow channels for connecting pipes, which is much easier to work around your existing layout.

Plus, for a small garden, catch basins are often more cost-effective and simpler to maintain. You can easily check and clean them periodically by just lifting their grates, whereas maintaining a French drain in a small space can be trickier.

For an established garden, would you recommend the French drain system over catch basins, or does it depend on the garden layout? I am asking for a small garden with plants mostly at corners and only a small tree at the center.

The most garden-friendly approach is starting with a French drain system. Think of it as creating an underground pathway for water to escape. First, you'll want to observe how water naturally flows in your garden during wet conditions – this helps identify the best route for your drain. The ideal path runs from the wettest areas to a lower point where water can safely exit, like a drainage ditch or storm drain.

For installation, you'll need to carefully dig a trench about 18 inches deep and 12 inches wide. The trick in an established garden is to dig in sections and work around your plants' root systems. Line the trench with landscape fabric (it keeps soil from clogging your system), add about 2 inches of gravel, lay in a perforated pipe with the holes facing down, then cover it with more gravel and wrap the fabric over the top. The final step is covering it with soil, and you can even replant right over it.

A less invasive alternative is installing catch basins – think of them as strategic collection points for water. You can place these at key low points in your garden, connecting them with smaller pipes that lead to your main drainage point. This approach requires less digging across your garden.

The key to success is working gradually and carefully around your existing plants, almost like doing garden surgery.

Thank you for the advice. Can you please explain how would I go about installing proper drainage systems in a garden that’s already established?

First thing you'll want to do is help your garden breathe a bit. Start by creating some simple drainage channels – think of them as little escape routes for all that excess water. Just grab a spade and dig some shallow trenches to guide the water away from your precious plants. While you're at it, clear away any leaves or debris that might be blocking the water's natural flow. If you've got any potted plants sitting in puddles, give them a lift to higher ground – they'll thank you for it. Keep an eye on your larger plants too; some might be leaning under the weight of all that water and could use a bit of support with some stakes. For the longer term, your soil is going to need some TLC. Once things dry up a bit, mixing in some compost will work wonders for drainage. Just be careful not to walk around too much on soggy soil – it compacts easily and can make drainage problems worse in the future. You might want to think about creating some raised beds or installing proper drainage solutions if this is a recurring problem.

Looking ahead, consider planting some water-loving plants in the naturally lower areas of your garden. They'll actually help soak up some of that excess water, turning a problem into a feature. And don't forget about prevention – keep your gutters clear and make sure water flows away from your garden, not into it.
