When is the best time to apply compost and mulch to your flower garden? Well… spring, summer and fall are all great times to give your plants a “little something” to help them be the best they can be. It all can be a little confusing, especially if you’re new to gardening, but hopefully the following will help you to understand the best times for adding these amendments to your soil.
Springtime is a great time to work in compost and about 1 cup of worm castings (see video below), around each annual or perennial that you are planting. For any established perennials, it’s best to wait until fall to feed them any extra food.
If you plan on preparing a whole bed, simply work in as much as 1/2 inch layer of compost or 10 pounds of an organic fertilizer blend. It’s best to wait about three weeks after planting to cultivate and mulch so that the soil will warm up. Warm soil helps the activity of beneficial soil micro-organisms and we certainly want their help! Use only 3 or 4 inches of pine fines or 2 inches of rich compost like worm castings, to mulch around your flowers.
Be sure not to use large wood chips around annuals or perennials as it is too toxic for the plants. Only use pine fines or a smaller mulch pellets for these plants.
Feeding the foliage on your flowering plants at least 3 times during the season with fish and kelp extracts is a good task for the summer. For best results, mist early in the morning being sure to cover leaves completely with spray, especially the undersides of leaves.
Summer is also a great time to test your soil pH so you’ll be ready for fall planting. You can pick up soil testing kits from our local extension service or purchase a kit at most home garden shops or have a local landscaper to do this.
Of course be sure to keep your flowers watered well with about 2 inches of water a week. It’s best to do this in early morning so that the sun can dry the leaves which helps keep fungus and disease from setting in due to wet foliage. Feel free to mix in kelp, fish, or compost tea (using comfrey tea is great!)
Fall is absolutely the perfect time to fertilize most well established perennials in your flower garden. If you have mulch around them, simply pull it back and sprinkle the soil with a little fertilizer. You don’t want to apply too much fertilizer to established perennials as they may collect too much mineral content from the soil and spread too aggressively; therefore, overgrowing it’s intended spot in your garden! No one likes a pushy plant, right?
