When is too late to plant summer flowering plants?

Summer is finally upon us and it’s not too late to start on that garden! Planting and maintenance are hard work, and not everyone has the time to meticulously plan for their summer flowering garden. Or even the knowledge of when to start it!

In the world of gardening there are two primary seasons to start planting – spring and autumn. For spring, we plant bulbs like gladioli that will eventually blossom in summer. For autumn, we plant bulbs such as daffodils that will bloom in spring. However, there is still a prime time for planting during summer that will allow your gardens to thrive well into late autumn so you don’t miss out on having a spectacular display.

How to plant Summer Flowering Bulbs

This guide on how to plant Summer Flowering bulbs will have your garden blooming right on time for the upcoming season. Planting bulbs is a super easy way to make your garden ready for summer. Whether you are aiming to show off some beautiful boarders or create a dynamic display with pots, this guide will show you how!

The best time to plant your Summer Flowering bulbs is during the season before – Spring. Summer bulbs need warm weather and warm soil to grow which makes April and May the best time to start planting if you want your flowers to bloom on time.

Step 1: Check the size

To ensure that your bulbs grow correctly it is important that you make sure you know the size of the bulb. As they need to be planted at two to three times their depth, ensure you dig a hole wide enough and deep enough for the bulb to fit.

Step 2: Spacing

When figuring out how to lay out your garden, ensure that the bulbs are spaced out at least twice the bulbs own width apart. Then place the bulbs in the hole with the tip or shoot facing upwards towards the sky. Replace the soil and firm. Be careful not to tread too heavily as this could damage the bulbs.

Step 3: Water

Water your plants straight after planting. Then make sure they are watered regularly, but allow the soil to dry in between watering.

Step 3: In the green

Don’t forget about those boarders! Remember to plant your pot-grown bulbs in the desired boarder position for them to flower. Make sure the hole is the same depth as before but deep and wide enough to allow the roots to spread.

Tips:

  • As most bulbs are acquired and planted when dry and dormant, plant them as soon as possible. If left in storage too long they may flower poorly.
  • Regularly check that the bulbs are healthy and be on watch for any pests including slugs, snails and squirrels. Also, keep the area weed-free to ensure your plants are taking in as much nutrients as possible.
  • For a display: plant in groups of at least six to create a wonderful display. The more plants the better!
