Don’t over fertilize plants using these mixes as generally very little is required to boost your plants. For instance, using too much comfrey tea in your garden could introduce too much potassium to the soil. This can lead to stunted plant growth over time.
Chop or tear these up a bit and place in bucket, then cover with water (ideally rainwater). Try to weigh down the leaves with something heavy, such as a stone. Cover the bucket to keep insects from laying eggs in it. After about a month, strain the contents and dilute it in about 15 parts water so that you can spray the tea on your plants.
Try to let leaves wilt for a few hours after harvesting before using in the garden, to prevent them from sprouting.
Chop up the leaves in a bucket, cover them with rainwater and wait a month. Use this in a diluted form as a liquid fertilizer.
Take about a tablespoon of dried horsetail. Add 2 liters (0. 5 US gal) of rainwater and boil it up in a big pan, simmering for half an hour. When cool, store in a glass container. To use it in the garden, dilute in 5 parts of rainwater and spray this on your plants every ten days to help them resist fungal infections and rust.
Sprinkle used coffee grounds around the base of your plants, where the grounds will also act as mulch. Avoid putting the coffee over the exposed rhizomes of plants such as iris as this could lead to rot. Alternately you can add a few cups of used coffee grounds to a watering can (pick one with a wide spout or it will clog a fine watering rose or narrow spout). Cover the grounds with water and let the mixture sit for a few days before using it.
Seaweed should be used in the same way you would use manure. However, unlike fresh manure, it does not need to be rotted down first. Dig it into the garden before it dries out. Chop it up a little if your seaweed is in very long tangled strands. You don’t need to worry about the salt content as it is usually too low to affect your plants and soil. You can also make seaweed tea in a similar manner to comfrey tea, but leave the mixture to infuse for two months.
Stir this into ten cups of compost and use for your plant tomatoes.
