What to plant and sow in the garden in summer? Garden care and how to prepare seedlings and transplant

Summer is a good time of production for orchards (whether urban or in the field), provided that the weather is not extreme, that irrigation is present in its proper measure and that the care is correct.

A summer garden is one that is carried out in a specific climate with a temperature that can range from a minimum of 10ºC to a maximum of 40ºC. The summer garden responds to a warm climate and without too much rainfall, so irrigation must be adjusted to the specific climate of each place, to the rainfall that exists throughout the season, and although there is no general rule on watering in summer should be abundant because with high temperatures it is easy for plants to dry out.

We also advise you which organic seeds to use , the best planters, growing boxes and tables for your garden and essential books to learn everything about organic gardening .

Irrigation is essential and we will use a constant and gentle type of irrigation or a more sporadic, but deeper one depending on the type of plant that we plant in our garden.

The garden will also need to have abundant hours of light , a minimum of 6 hours of direct light per day and a maximum of 8 hours is recommended. The amount of direct light that the cultivated plants receive will influence the humidity of the soil and we must apply periodic waterings according to the characteristics of our garden to ensure that the plants can grow correctly, strongly and give us good harvests.

In a summer garden it is important to take pests into account , since it is a time of year when the weather is favorable for their birth and expansion .

The most common and well-known pests of summer are the following:

Common aphids that are easy to eradicate, the whitefly, which is attracted to the aphid; ants, beetles and mealybugs, butterflies, snails, caterpillars and worms, spider mites, moles, mice and birds. You can read a lot of useful information on how to prevent and treat pests in an ecological way .

We will also need to pay special attention to certain cultural tasks , that is, to those actions necessary so that the plants can grow and develop in optimal conditions to be able to get the most out of them.

In addition, we must nourish the cultivation soil with diatomaceous earth , worm humus , compost or biopreparations to enrich and increase its fertility. It is also beneficial to mulch or mulch the soil , and perform certain maintenance tasks such as pruning the leaves and parts of the plants that need it, performing the tutoring , that is, setting a guide so that they grow in a specific direction and vertically and upright, or control spontaneous plants and pests.

During the summer it is a good time to plant a great variety of plants and take advantage of the fact that it is a moment of flash and boom in the garden.

Among the vegetables that we can harvest at this time are for example: celery, celeriac, aubergine, zucchini, onions, cauliflowers, kohlrabi, endives, strawberries, broad beans, fennel (in areas with an Atlantic climate), beans and beans, chillies , lettuce, potatoes, cucumbers, peppers, leeks, radishes, beets, cabbage, arugula, tomatoes and carrots (Atlantic climate zones).

In summer it is also time to plant vegetables that we can take advantage of a few months later, such as artichokes in areas with a Mediterranean climate, broccoli, cabbages and turnips.

In order to harvest these plants we have two options, firstly, we can use seeds or we can save the sowing and buy a stock of the vegetables that we want to grow.

In the case that you want to carry out the whole process, and therefore use seeds to start your garden, which is cheaper, it is important that you know how to prepare seedbeds. In the event that you decide to use a plant, you can skip the next paragraph and go directly to the transplant process.


How to prepare the seedlings step by step

  • First, you will need a container with holes to use. You can buy a seedbed in a store or make your own seedbed using recycled elements such as containers, tetrabriks, yogurts, finished toilet paper rollers, used plastic cups, etc. It is important that in all the containers you make holes in the lower part so that the irrigation water does not stagnate and produce fungus or rot the seeds.


  • Once we have the containers, it is time to place the soil or substrate. You can make your own fusion with two parts of soil and one of compost and we recommend that you can place drainage elements at the bottom of the containers, such as stones and a thin layer of sand.


  • Compact the substrate slightly, but without producing excessive pressure, that is, air and irrigation water can circulate.


  • Water the substrate with a sprayer or spray so that it remains humid but without producing an excess of water that creates ponding.


  • Place the seeds. At this point it is important to find the necessary information to carry out a correct sowing according to the type of plant you are going to use. Each of the seeds has specific characteristics and must be sown at a specific depth and must be alone or with more seeds in the same hole in the seedbed. Follow the guidelines and indications depending on the type you plant.
  • Create labels to know what you have planted in each hole and to make it easier to keep track of its growth and its needs.
  • Carry out the waterings periodically, at first with the sprayer and, later, when the seeds have germinated, with a little water directly. With the seedbeds it is easy to control the humidity and temperature of the soil, which enables good germination and growth.
  • Now is the time to triar the plants and remove the leftovers. If more than one germination has appeared in the same seedbed, it will be necessary to eliminate the weakest and let the strongest one grow.


  • Let it grow about 8cm or wait for about 4-6 leaves to emerge and proceed to transplant.

When and how to transplant?

If you have bought a plant, it is ready to be transplanted. If you have created your own seedbed, you will have to wait for the plants to exceed about 8 cm above the ground level or for them to already have 4 or 6 grown leaves.

  • For transplanting, it is important to carefully think about the location of each plant taking into account the associations and crop rotations . Therefore, before transplanting the plant to your garden you should make a small sketch of how you will organize your garden in a productive way.


  • Once you have the sketch, you must respect the appropriate distances so that each plant can develop in its entirety, leaving empty spaces between plant and plant. This is called a planting frame.


  • Make holes or holes in the ground approximately 12 cm deep.


  • Remove the seedling from its container carefully, open the roots of it a little and place it in the hole that you have dug.


  • Place soil around the hole created, tighten it generating pressure around the roots so that it is well supported.


  • Lightly water the surroundings of the plant, without wetting its leaves and press the soil a little more.

Once you have carried out the transplant, you will have to continue with periodic maintenance and care for your summer garden, since it is a delicate moment due to the high temperatures. You should dedicate time every three or four days, minimum.

Another care that you should take is watering. It is important to do it periodically and promote an adequate level of soil moisture .

With certain plants you should carry out the tutoring, since it is important both for their growth and to save space in the garden that they grow vertically. Thus, using some type of guide such as sticks or canes, you should tie the plants as they grow. Tomatoes or broad beans are a clear example of plants that must be trained.

Observe the earth and the reaction of plants to it. Perhaps they need an enrichment of this one due to lack of nutrients. Perhaps the soil is very acidic and the leaves turn yellow or pests may appear that you will have to fight. All these elements must be known and kept in mind in a summer garden.

Finally, and if you take proper care, you will be able to harvest and enjoy your own vegetables and greens and the reward will be very rewarding.
