I was thinking about it, and there’s Sanctuary from the book of cards : Sapien Medicine on Instagram: "Instuctions for use here; https://www.facebook.com/EnlightenedStates/posts/2307420672636268" (one needs to be attuned to the cards first)
This card works with helping you to create your own garden forest, It helps plants grow and nourishes them energetically,
You can activate the card then place it next to the plant you wish to work on or drawing the sigil in the dirt next to the plant then activating the energy.
This energy works on strengthening the plant’s own energy system, recovery and regeneration as well as directly telling it to grow stronger and healthier.
The works on the plant for 15 to 20 mins.
Also Devic intercession :
The Fae mandala might help too due to their connection to nature :
