been doing the bucket thing for 4 yrs now, you will need find buckets or grow bags

that hold 5 gal. of grow mix. One of the gardeners on this site shared the dirt mix recipe equal parts top soil, compost, pearlite and peat moss. I mix mine in a tumbling composter. You can also put ingredients on a tarp and fold the ingredients to gether. The following need 5 gal. Buckets cucumbers, tomatoes, any squash, egg plants,

2 pepper plants in a 5gal. Bucket, bush beans 3 plants, onions 4 plants, lettuce 4 plants, beets 4 plants, carrots 10, radish 10. You will also need some fertilizer if your soil mix doesn’t have good quality compost. Follow instructions for fertilizing on you fertilizer package. You may need epsom salt...it’s mineral called magnisium...it helps to set the flowers that make the fruits. The next would be calcium aka garden lime it help end blossom rot of the tomatoes. You might also have to hand pollenate your garden..not hard a soft artist water color brush tap the stamens and swish the brush..transfer to the next plant.

Start with what you intend to use. fill with soil. plant whatever you're planting. (pay attention to what isgrowing as some things can't be grown without expansion) What are you planning on growing??

Make sure you put holes in the bottom of the bucket for drainage. Put garden fabric down so the soil doesn't come out of the holes. Put a few inches of gravel or rocks for drainage help. I use a good potting soil and add about a third of peat moss. If you do use fertilizer, use one for veggies if that is what you are planting, keep to the schedule on the package as potted plants go through the fertilizer more so than in the soil. If you do a tomato, get a spray made specifically for blossom end rot. It is a calcium supplement you spray on the leaves to prevent blossom end rot, which you will get with potted tomato plants. I had a huge pot I planted a tomato in this year and six in my garden and the potted one was the only one that got blossom end rot. You spray the tomato leaves just before the tomatoes start ripening. It didn't effect the green ones and the green ones on the plant after I sprayed it didn't get blossom end rot. I found mine at a local greenhouse that I have dealt with for years.
