Hi Claire and welcome to GoY, could you amplify your question a bit please. Are you talking about pot plants or a large indoor garden.

If you mean for potted houseplants, none really, other than a container for watering with and occasionally, either a sharp pair of scissors or secateurs for trimming. Possibly a pair of marigolds for repotting!

pot plants and indoor greenhouses
and also window boxes

Ah, well in that case, hand fork and trowel, and maybe a dibber if you want to grow stuff from seed.

... And a brush and dustpan ;o)

lol Myron!

I just borrow a fork from the kitchen drawer - oops, shouldn't have said that!

Yes,oops,Bulba ! ... and where do all those non matching spoons come from ? not to mention an old pastry brush,for dusting the leaves,on a Christmas Cactus in the Bathroom..when I remember..due anytime now ...:o) no need for any special tools,Clare,if you have a cutlery drawer ..

The kitchen can provide quite a few useful gardening tools. A dining fork is handy for losening the soil in a pot, a dining knife for digging weeds out between paving stones, teaspoons and desert spoons as measuring devices, a carving knife often comes in handy, vegetable brush for washing pots and various seives are used for sifting seeds or removing fines from grit.
I am sure that others have different 'tools' that mysteriously have left the house.

But you surely would use a hand fork for a large trough, Bulba, I can't imagine faffing about with a cutlery fork in one of those. As for brushing dust off leaves, old blusher/make up brushes are good for that, and I have always pricked out seeds with the end of a small paintbrush, perfect size for small seedlings. And no one's mentioned a breadknife, which has to be the most indispensible bit of kit for sawing through solid rootballs....

Household paint brushes are good for dusting/brushing away soil, and I reuse those spray bottles with a trigger that contained window cleaner, etc, for misting plants with water.

I use empty spray bottles too,Myron..well washed out of course..and don't get me started on all the plastic containers from supermarkets..The ones with Strawberries make great little propagators..already got the drainage holes and a lid and great for growing Cress as well ,to name a couple..I have a shelf full of assorted ones in the shed with all manner of things in..all see through,so I can see at a glance.. Lol.

thank you i am doing an alevel project based on indoor gardening the feed back on this question is very helpfull, i will be asking questions soon but thank you again

Yes Bloomer, I'm the same. Lots of things that are thrown away can be used for things to do with horticulture. I started to bring home those clear plastic beakers from work. The ones that are by the water cooler, used once and discarded. A few holes in the bottom and they are ideal for seedlings. Because they are clear, you can see the roots forming. I also use them for measuring cups and for putting over plant cuttings to keep the moisture in.

hi Bamboo nope no using a hand fork for a trough a very small ex kitchen fork - remember our troughs are full of alpines :)

Snap,Myron..those plastic cups were my first venture into seed sowing,years ago ,when I still lived with my mum..not the best results in the world,as I sowed the whole packet,and I think most of them germinated..Imagine the pricking out? rows and rows on every windowsill,and one by one they died..all except one..and my mum and I,nurtured this little plant with love..which turned out to be a Dandelion ! Lol...But that's when the bug got to me,and I have loved it ever since..I have learned from experience,I don't need to sow the whole packet..:o)
