As there is little soil in a pot or in a flower box, water and nutrients it contains are quickly drawn by plants. For they have good growth and they bloom profusely, annual flowers grown in container must be carefully planted in a soil rich.

Timing

The ideal time to undertake the planting of most annual plants of tropical origin is when all danger of frost is practically zero in a given region. In Montreal and in several municipalities in zone 5, this occurs around May 20, around Victoria Day. In Quebec and some other regions located in zone 4, it should usually wait until the end of May or early June to set ground annuals. In the northern regions, it is best to begin planting annuals around mid-June.

Stocky plants

Although it is normal to be attracted to plants in full bloom, I recommend instead of opting for annual devoid of flowers, but carry a lot of buds. Also avoid etiolated plants, and choose those that are short and squat, because their recovery is better after planting.

The horticultural market today offers an impressive variety of pots, flower boxes and hanging baskets. Containers are ideal for light colors, to prevent overheating and drying out too fast potting soil, and large, to provide maximum space to plant roots that are planted. It is also important to learn about the frost resistance of containers that you buy. Pots made of plastic, wood, metal or cement are usually not affected by frost and can overwinter outdoors provided they are returned and covered with an impermeable plastic sheet, while that the majority of containers of unglazed terracotta should ideally be stored in a place beyond the reach of frost during the winter.

Rich soil

We can make yourself an excellent growth medium by mixing equal parts of compost, peat moss and perlite. A word of caution, however:

# Do not stir fresh manure to the soil, as it decomposes, it inhibits the growth of rootlets.
# Also avoid using the earth to make your garden flourish.
# To simplify your task, you can use a specially designed substrate business for the cultivation of plants containing them, such as Pro-Mix organic.
# Make sure you choose the soil contains compost.
# I would also add to the soil that you have purchased or made yourself a natural fertilizer rich in potassium which slow release formulation is similar to 5-3-8. You can provide about 15 ml (one tablespoon) 30 ml (a handful) of fertilizer per plant.
# For efficiency, combine all ingredients needed to make compost in a wheelbarrow or large container by wetting everything well.

Planting

# Before planting annuals, it’s essential to water their roots.
# If their mound is particularly dry, soak a few minutes in a pan containing a little water.
# Sit on a table, protected from the scorching rays of the sun of the afternoon, to be perfectly at ease to do the planting.

It is recommended not to have pebbles in the bottom of the container, since they occupy the space of the soil that plants need so much.

# It is best to drill a few holes to allow excess water flows easily.
# It takes at least a hole 1.5 cm in diameter every 30 cm.
# To promote a better flow of water and thus prevent the soil blocks the drainage hole, cover it with a broken pot or a small flat stone.

Each plant should be arranged so that its neck – where the stem joins the roots either on the same level as the soil surface.

# Add soil around the plants and tightly packed with the fingertips, but not too compact it.
# After covering the drainage hole, fill the container two thirds with potting soil moist by tamping down lightly on the sides.
# Each plant must be arranged so that its neck where the stem joins the roots is located flush with the soil surface.
# Add soil around the plants and tightly packed with the fingertips, but not too compact it.

The surface of the compost should be about 2 or 3 cm below the rim of the container to allow the irrigation water not overflow.

# Once all the plants installed, water slowly into the soil two or three shots.
