Sweet Lemon (Mausami) Tree Pollination 

Sweet Lemon (Mausami) Trees are self-fertile. You will get fruit with only one plant. However, adding an additional Sweet Lemon (Mausami) Tree will drastically increase the size of your crop.

Planting & Care 

It’s Easy to Plant & Care for Your Sweet Lemon(Mausami) Tree

 

Outdoor Planting Instructions: If planting outdoors, choose a spot in your yard that receives at least 6 hours of sun every day. Make sure the soil is well-drained. Sweet Lemon(Mausami)’s do not do well in overly moist soils. Sandy, loamy soils are ideal. Dig a hole in the ground that is twice as wide as the root ball. Place your tree in the hole, with 1 inch of the root ball sticking out from the top of the soil. Water thoroughly after planting. Add a thick layer of mulch around the base of the tree, but keep the mulch 6 inches away from the tree trunk.

 

Container Planting Instructions: Plant your tree in a large pot that gives the roots room to grow. Plant in well-draining, loose soil and make sure your container has proper drainage holes. Adding equal parts sand, moss and vermiculite is the best combination for ideal growth. As your tree grows, if roots begin to come out of the drainage holes, you will need to repot your plant in a larger container.   You can keep your plant outside during the warmest months, but when temperatures begin to drop below 60 degrees Fahrenheit, you’ll need to begin training the tree to move indoors. Training is easy, simply bring your tree inside for 1 hour on the first day and increase the time inside by 2-3 hours each day. If you move your plant back outside during the summer, you’ll need to retrain it in the same way. Always keep your tree in the sunniest location possible, whether indoors or outdoors.

 

Watering: Water new plants twice a week until established. Once the tree is established, only water every 7-10 days. Never overwater your Sweet Lemon(Mausami) tree.

 

Fertilization: Use a citrus fertilizer in March, May and June. Follow the instructions on the package, but divide the amount by 3. When applying the fertilizer, water the tree lightly to dissolve the fertilizer into the soil.

 

Pruning: Prune in the spring when new growth emerges. Remove all dead and dying limbs or branches that grow from the bottom of the tree. During the first 2 years of growth, remove all the fruit once the blooms have died. This allows the tree the ability to use all the nutrients, and it encourages new growth.

 

Pests: When watering your tree, spray the leaves and branches with a hose to knock off any larva or eggs.  If you see any eggs, larva or worms sprayed off, be sure to put them in a sealed trash bag and throw them away to prevent them from re-inhabiting the tree. You may also spray your tree with insecticidal soap in Spring. If your tree becomes infested, you will need to use an insect oil to rid the tree of pests and prevent diseases.

Harvesting: Sweet Lemon(Mausami)s should be harvested as soon as they being to turn orange. They will continue to ripen on the branch, and can spoil very quickly, especially during the rainy season.

Storage: Sweet Lemon(Mausami)s can be kept at room temperature for up to a week, in the fridge for up to 2 weeks and in the freezer for a year. To freeze Sweet Lemon(Mausami)s, peel and cut them into wedges. Boil simple syrup and pour over wedges. Freeze in an airtight container.

LAND PREPARATION

Land should be ploughed, cross ploughed and leveled properly.

SEED

SEED RATE 
Minimum plant density of 111 plants/acre should be maintained.

SOWING

TIME OF SOWING
The best season for planting is from middle of June (with onset of monsoon) to end of September.
To minimize effect of strong wind during initial growth stage, plant Mango, Guava, Jamun, Aonla, Shisham or Mulberry on field boundaries.

SPACING
Spacing between plants should be kept between 6×6 m.

SOWING DEPTH
Pits of size 60×60×60 cm should be dug for planting seedlings.

METHOD OF SOWING
Propagation in Sweet Lemon (Mausami) is done by T budding method. It is usually budded on rough lemon (jambhiri, Soh-myndong or jatli khatti) rootstock. It is also budded on kharnakhatta rootstock.

Sow citrus seeds in nursery on bed of 2 m x 1 m size and with 15 cm distance between the rows. When seedlings are of 10-12 cm height, transplanting is to be done. Select healthy and uniform size seedling for transplantation purpose. Remove dwarf and weak seedlings. If needed, pruned roots slightly before planting. In nursery, Budding is done when plants are of pencil thickness. Shield budding or T shape budding is done for that, T shaped slot is made in bark of tree at distance of 15-20 cm from ground. Horizontal cut of about 1.5-2 cm long is given, and vertical cut of 2.5 cm long is made from middle of horizontal cut. Remove bud from bud stick and insert it into T shape slots, afterward wrapped it with plastic paper.
T budding is done during February-March and also in August- September.

INTERCROPS

Take intercrop in young and nonbearing orchards. Take pea, moong, mash, cowpea and gram as intercrop. Take intercrop up to four years.

PRUNING AND TRAINING

It is necessary for healthy growth of branches and plant. It can be done at any time but best time for pruning is after harvesting of fruits. Avoid pruning when plant is at active growth stage. Remove diseased, injured, dropping branches and dead wood periodically.

For eight years and above crop, apply cowdung@100 kg, Urea@1920 gm and SSP@2750 gm per Tree.

Apply whole amount of cowdung during December month whereas apply Urea in two parts; apply first of Urea in February, and second dose in April-May month. At time of applying first dose of Urea, apply whole dose of SSP fertilizer.

If fruit drop is observed, to control excessive fruit drop, take spray of 2,4-D@10 gm in 500 Ltr of water. Take first spray in March end, then in April end. Repeat the spray in August and September end. If cotton is planted in nearby field of citrus, avoid spraying of 2,4-D, instead take spray of GA3.

WEED CONTROL

To control weed, take post emergence spray of Glyphosate@1.6 Ltr/acre or Paraquat@1.2 Ltr per acre mixed in 200 Ltr of water.

IRRIGATION

It requires frequent watering at initial growth years. Apply irrigation at weekly intervals to 3-4 years old crop. For older tree apply irrigation at interval of 2-3 weeks depending upon soil type, weather conditions and rainfall. Avoid flood irrigation as it causes disease like root rot, collar rot etc. Always apply light irrigation with high frequency for optimum yield. Irrigation before sprouting and after fruit set is crucial stage of irrigation.

PLANT PROTECTION

Pest and their control:

Psylla: It attacked crop at any stage of growth. Nymphs are of orange color whereas adult of Psylla is of gray color. They suck sap from leaves, young shoots. It causes drying and curling of leaves. This pest causes die back, greening and citrus decline and ultimately results in heavy damage.

If infestation is observed on young shoots, take spray of Triazophos+ Deltamethrin@2 ml or Profenofos+ Cypermethrin@1 ml in 1 Ltr of water or Quinalphos@1 ml or Acephate@1 gm or Imidacloprid@5 ml/Ltr of water. If necessary repeat the spray with interval of 15 days.

Leaf Miner: It is serious pest of citrus. It can cause yield loss up to 20% depending upon severity. They attacked on tender leaves and shoot and make serpentine mines on leaves. In severe infection, defoliation is observed.

If infestation is observed, to control, take spray of Profenofos 50EC@60 ml/15 Ltr water 2-3 times at 8 days interval on new flesh. If necessary repeat the spray with interval of 15 days. Or take spray of Fenvalerate@500 ml or Trizophos@250 ml or Imidachloprid@200 ml or Chlorpyriphos@800 ml in 200 ltr of water.

 

Aphid: Serious and common pest of citrus. Adult and nymphs, both suck the sap thus weaken the plant. In severe infestation, they cause curling and deformation of young leaves. They secrete honey dew like substance and sooty, black mould is developed on affected parts.

If infestation is observed to control take spray of Dimethoate@10 ml or Methyl Demeton@10 ml per 10 ltr water on new flush.

 

Mite: If infestation is observed, to control Citrus Mite, spray with Dicofol@1.75 ml or Wettable Sulphur@3 gm/ltr of water. Take second spray after 15 days if needed.

Mealy Bug:  If infestations of sucking pests like Mealy bug is observed then to control spray with Chlorpyriphos 50EC @500 ml/100 ltr of water.

Leaf folder: Larvae web leaves together and feed inside it. It affects plant growth and plants become stunted.

If infestation is observed take spray of Chlorpyriphos@1250 ml or Quinalphos@800 ml in 200 ltr of water.

Whitefly and Blackfly: Serious pest of citrus crop. Adult and nymphs, both suck the sap thus weaken the plant. Affected plant gives yellowish appearance in severe infection curling of leaves if observed. They secrete honey dew like substance and Sooty, black mould is developed on affected parts. Black fly lay eggs on lower side of leaves, nymphs are of black color.

If infestation is observed, take spray with Acephate@1.25 gm or Quinalphos@1.5 ml or Imidacloprid@2 ml/ litre of water. If necessary take second spray at interval of 15 days.

 

Disease and their control:

Canker: Symptoms can be seen on leaves, branches and fruits. Initially yellow spots observed on leaves, it get enlarges and become brown, rough and raised on both side.
