It’s May, and Window sills, greenhouse, and polytunnels are all jam-packed with seedlings that seem to pop up all over the place. Although the temperatures have climbed a little, you should resist planting too many crops. There are still frosts, and nothing is worse than getting caught out with a late frost and losing your young tender plants.
With the start of the very first horticulture shows starting to appear, it marks the start of some exciting times. Most gardeners are probably putting as much time into their gardens as they do their full-time jobs at the moment. But it will all be worth it over the next few months.
Winter still has its grasp upon the garden, but before we know it, the last frost date will come and go. Then all hell will break loose, and we will be in a freefall into summer. This is what we have all been waiting for, so enjoy it.

Set up beer traps
May is the time when slugs really start to take hold. They decimate your young seedlings, so taking control of the situation can mean the difference between a great season and a rubbish season. Putting out beer traps is perfect as these attract the slugs to the cheap larger you put in them. You can simply dispose of them every few days.
I see it many times on social media platforms. People screaming to help them with slugs. I have produced two videos to help anyone who suffers from this pest. So check them out below. NEVER worry about slugs again.
Consider companion planting
There are so many benefits to companion planting. It saves on space, controls pests, can help with pollination and provides habitat for many insects and wildlife. But one of the main reasons is that it can increase the productivity and yields of your plants.
Check for sawfly on Gooseberries.
Sawflies can be a real nuisance for gooseberries, along with other plants. The female sawfly has a saw-like appendage on the tip of the body, and they use this to create a hole in the soft tissue of a leaf. There she will lay an egg. As this hatches, it will destroy the leaves from the inside out.
Pruning your gooseberries to a goblet shape will really help to control sawflies as they do not like the added ventilation this would provide to the plant. Also, the light helps to kill off the eggs. This is the single biggest way to control this pest.
Support tall perennials
As perennials start to grow, it is important to support them, If we have any sort of wind, they will be flattened, which really makes a mess of the plant. It can also damage the root system due to wind rock. Ideally, the support structures for these plants should be placed now. This will allow the perennials to grow around the support. This will help protect against heavy winds and the weight of rain.
This month you should start to deadhead your camellias, Simply removing the dead flower heads will help to keep the plant producing blooms, This is not the same as pruning, we are not trying to shape the plant. Just remove flower heads to prevent them from going to seed and wasting the plant’s energy.
Plant out pot-grown shrubs
Now is the last time in which to plant pot-grown trees and shrubs safely. When doing this, avoid areas that get waterlogged. Dig a square hole much bigger than the rootball. Square hole? I hear you cry. That’s right. A square hole.
Square holes are better for one main reason. When you plant in a square hole, the roots hit a corner and push into the new soil. When you plant trees into a round hole, the roots continue to grow around in circles, and as they mature, they strangle each other.
Mulch Mulch Mulch
If you want an easy life in the garden, mulching is one of the best things you can spend your time on. This has a huge amount of benefits.
- It cuts down on weeds.
- It keeps root zones cool.
- Retains moisture
- Keeps warmth in the soil.
Putting a good 4-6 inches of mulch around your garden is a real-time saver. Don’t forget to do this task as it will free you up to complete other duties later in the year instead of weeding.
Sow beans in root trainers or pots
Large climbing plants such as beans, peas and corn benefit from being planted into root trainers. This helps the roots to go downwards rather than in a circle like most pots. This allows the plant to have a sturdier root system which will support the plant as it grows taller.
